Chapter 1. Introduction

The FreeBSD Ports Collection is the way almost everyone installs applications ("ports") on FreeBSD. Like everything else about FreeBSD, it is primarily a volunteer effort. It is important to keep this in mind when reading this document.

In FreeBSD, anyone may submit a new port, or volunteer to maintain an existing unmaintained port. No special commit privilege is needed.

Chapter 2. Making a New Port

Interested in making a new port, or upgrading existing ports? Great!

What follows are some guidelines for creating a new port for FreeBSD. To upgrade an existing port, read this, then read Upgrading a Port.

When this document is not sufficiently detailed, refer to /usr/ports/Mk/bsd.port.mk, which is included by all port Makefiles. Even those not hacking Makefiles daily can gain much knowledge from it. Additionally, specific questions can be sent to the FreeBSD ports mailing list.

Only a fraction of the variables (VAR) that can be overridden are mentioned in this document. Most (if not all) are documented at the start of /usr/ports/Mk/bsd.port.mk; the others probably ought to be. Note that this file uses a non-standard tab setting: Emacs and Vim will recognize the setting on loading the file. Both vi(1) and ex(1) can be set to use the correct value by typing :set tabstop=4 once the file has been loaded.

Looking for something easy to start with? Take a look at the list of requested ports and see if you can work on one (or more).

Chapter 3. Quick Porting

This section describes how to quickly create a new port. For applications where this quick method is not adequate, the full "Slow Porting" process is described in Slow Porting.

First, get the original tarball and put it into DISTDIR, which defaults to /usr/ports/distfiles.

These steps assume that the software compiled out-of-the-box. In other words, absolutely no changes were required for the application to work on a FreeBSD system. If anything had to be changed, refer to Slow Porting.

It is recommended to set the DEVELOPER make(1) variable in /etc/make.conf before getting into porting.

# echo DEVELOPER=yes >> /etc/make.conf

This setting enables the "developer mode" that displays deprecation warnings and activates some further quality checks on calling make.

3.1. Writing the Makefile

The minimal Makefile would look something like this:

PORTNAME=	oneko
DISTVERSION=	1.1b
CATEGORIES=	games
MASTER_SITES=	ftp://ftp.rediris.es/sites/ftp.freebsd.org/pub/FreeBSD/

MAINTAINER=	youremail@example.com
COMMENT=	Cat chasing a mouse all over the screen
WWW=		http://www.daidouji.com/oneko/

.include <bsd.port.mk>

Try to figure it out. A more detailed example is shown in the sample Makefile section.

3.2. Writing the Description Files

There are two description files that are required for any port, whether they actually package or not. They are pkg-descr and pkg-plist. Their pkg- prefix distinguishes them from other files.

3.2.1. pkg-descr

This is a longer description of the port. One to a few paragraphs concisely explaining what the port does is sufficient.

This is not a manual or an in-depth description on how to use or compile the port! Please be careful when copying from the README or manpage. Too often they are not a concise description of the port or are in an awkward format. For example, manpages have justified spacing, which looks particularly bad with monospaced fonts.

On the other hand, the content of pkg-descr must be longer than the COMMENT line from the Makefile. It must explain in more depth what the port is all about.

A well-written pkg-descr describes the port completely enough that users would not have to consult the documentation or visit the website to understand what the software does, how it can be useful, or what particularly nice features it has. Mentioning certain requirements like a graphical toolkit, heavy dependencies, runtime environment, or implementation languages help users decide whether this port will work for them.

The URL that used to be included as the last line of the pkg-descr file has been moved to the Makefile.

3.2.2. pkg-plist

This file lists all the files installed by the port. It is also called the "packing list" because the package is generated by packing the files listed here. The pathnames are relative to the installation prefix (usually /usr/local).

Here is a small example:

bin/oneko
man/man1/oneko.1.gz
lib/X11/app-defaults/Oneko
lib/X11/oneko/cat1.xpm
lib/X11/oneko/cat2.xpm
lib/X11/oneko/mouse.xpm

Refer to the pkg-create(8) manual page for details on the packing list.

It is recommended to keep all the filenames in this file sorted alphabetically. It will make verifying changes when upgrading the port much easier. The sorting should be applied after variable expansion takes place. The framework does this correctly when the package list is generated automatically.

Creating a packing list manually can be a very tedious task. If the port installs a large numbers of files, creating the packing list automatically might save time.

There is only one case when pkg-plist can be omitted from a port. If the port installs just a handful of files, list them in PLIST_FILES, within the port’s Makefile. For instance, we could get along without pkg-plist in the above oneko port by adding these lines to the Makefile:

PLIST_FILES=	bin/oneko \
		man/man1/oneko.1.gz \
		lib/X11/app-defaults/Oneko \
		lib/X11/oneko/cat1.xpm \
		lib/X11/oneko/cat2.xpm \
		lib/X11/oneko/mouse.xpm

Usage of PLIST_FILES should not be abused. When looking for the origin of a file, people usually try to grep through the pkg-plist files in the ports tree. Listing files in PLIST_FILES in the Makefile makes that search more difficult.

If a port needs to create an empty directory, or creates directories outside of ${PREFIX} during installation, refer to Cleaning Up Empty Directories for more information.

As PLIST_FILES is a make(1) variable, any entry with spaces must be quoted. For example, if using keywords described in pkg-create(8) and Expanding Package List with Keywords, the entry must be quoted.

PLIST_FILES=	"@sample ${ETCDIR}/oneko.conf.sample"

Later we will see how pkg-plist and PLIST_FILES can be used to fulfill more sophisticated tasks.

3.3. Creating the Checksum File

Just type make makesum. The ports framework will automatically generate distinfo. Do not try to generate the file manually.

3.4. Testing the Port

Make sure that the port rules do exactly what is desired, including packaging up the port. These are the important points to verify:

pkg-plist does not contain anything not installed by the port.
pkg-plist contains everything that is installed by the port.
The port can be installed using the install target. This verifies that the install script works correctly.
The port can be deinstalled properly using the deinstall target. This verifies that the deinstall script works correctly.
The port only has access to network resources during the fetch target phase. This is important for package builders, such as ports-mgmt/poudriere.
Make sure that make package can be run as a normal user (that is, not as root). If that fails, the software may need to be patched. See also fakeroot and uidfix.

Procedure: Recommended Test Ordering

make stage
make stage-qa
make package
make install
make deinstall
make package (as user)

Make certain no warnings are shown in any of the stages.

Thorough automated testing can be done with ports-mgmt/poudriere from the Ports Collection, see poudriere for more information. It maintains jails where all of the steps shown above can be tested without affecting the state of the host system.

3.5. Checking the Port with `portlint`

Please use portlint to see if the port conforms to our guidelines. The ports-mgmt/portlint program is part of the ports collection. In particular, check that the Makefile is in the right shape and the package is named appropriately.

Do not blindly follow the output of portlint. It is a static lint tool and sometimes gets things wrong.

3.6. Submitting the New Port

Before submitting the new port, read the DOs and DON’Ts section.

Once happy with the port, the only thing remaining is to put it in the main FreeBSD ports tree and make everybody else happy about it too.

We do not need the work directory or the pkgname.txz package, so delete them now.

Next, create a patch(1), file. Assuming the port is called oneko and is in the games category.

Example 1. Creating a .diff for a New Port

Add all the files with git add ., then review the diff with git diff. For example:

% git add .
% git diff --staged

Make sure that all required files are included, then commit the change to your local branch and generate a patch with git format-patch

% git commit
% git format-patch origin/main

Patch generated with git format-patch will include author identity and email addresses, making it easier for developers to apply (with git am) and give proper credit.

To make it easier for committers to apply the patch on their working copy of the ports tree, please generate the .diff from the base of your ports tree.

Submit oneko.diff with the bug submission form. Use product "Ports & Packages", component "Individual Port(s)", and follow the guidelines shown there. Add a short description of the program to the Description field of the PR (perhaps a short version of COMMENT), and remember to add oneko.diff as an attachment.

Giving a good description in the summary of the problem report makes the work of port committers and triagers a lot easier. The expected format for new ports is "[NEW PORT] category/portname short description of the port". Using this scheme makes it easier and faster to begin the work of committing the new port.

After submitting the port, please be patient. The time needed to include a new port in FreeBSD can vary from a few days to a few months. A simple search form of the Problem Report database can be searched at https://bugs.freebsd.org/bugzilla/query.cgi.

To get a listing of open port PRs, select Open and Ports & Packages in the search form, then click Search.

After looking at the new port, we will reply if necessary, and commit it to the tree. The submitter’s name will also be added to the list of Additional FreeBSD Contributors and other files.

Previously it was possible to submit patches for new ports using a shar(1) file; this is no longer the case with the evolution of git(1). Committers no longer accept shar(1) files as their use is prone to mistake and does not add the relevant entry in the category’s Makefile.

Chapter 4. Slow Porting

Okay, so it was not that simple, and the port required some modifications to get it to work. In this section, we will explain, step by step, how to modify it to get it to work with the ports paradigm.

4.1. How Things Work

First, this is the sequence of events which occurs when the user first types make in the port’s directory. Having bsd.port.mk in another window while reading this really helps to understand it.

But do not worry, not many people understand exactly how bsd.port.mk is working… :-)

The fetch target is run. The fetch target is responsible for making sure that the tarball exists locally in DISTDIR. If fetch cannot find the required files in DISTDIR it will look up the URL MASTER_SITES, which is set in the Makefile, as well as our FTP mirrors where we put distfiles as backup. It will then attempt to fetch the named distribution file with FETCH, assuming that the requesting site has direct access to the Internet. If that succeeds, it will save the file in DISTDIR for future use and proceed.
The extract target is run. It looks for the port’s distribution file (typically a compressed tarball) in DISTDIR and unpacks it into a temporary subdirectory specified by WRKDIR (defaults to work).
The patch target is run. First, any patches defined in PATCHFILES are applied. Second, if any patch files named patch-* are found in PATCHDIR (defaults to the files subdirectory), they are applied at this time in alphabetical order.
The configure target is run. This can do any one of many different things.
1. If it exists, scripts/configure is run.
2. If HAS_CONFIGURE or GNU_CONFIGURE is set, WRKSRC/configure is run.
The build target is run. This is responsible for descending into the port’s private working directory (WRKSRC) and building it.
The stage target is run. This puts the final set of built files into a temporary directory (STAGEDIR, see Staging). The hierarchy of this directory mirrors that of the system on which the package will be installed.
The package target is run. This creates a package using the files from the temporary directory created during the stage target and the port’s pkg-plist.
The install target is run. This installs the package created during the package target into the host system.

The above are the default actions. In addition, define targets pre-something or post-something, or put scripts with those names, in the scripts subdirectory, and they will be run before or after the default actions are done.

For example, if there is a post-extract target defined in the Makefile, and a file pre-build in the scripts subdirectory, the post-extract target will be called after the regular extraction actions, and pre-build will be executed before the default build rules are done. It is recommended to use Makefile targets if the actions are simple enough, because it will be easier for someone to figure out what kind of non-default action the port requires.

The default actions are done by the do-something targets from bsd.port.mk. For example, the commands to extract a port are in the target do-extract. If the default target does not do the job right, redefine the do-something target in the Makefile.

The "main" targets (for example, extract, configure, etc.) do nothing more than make sure all the stages up to that one are completed and call the real targets or scripts, and they are not intended to be changed. To fix the extraction, fix do-extract, but never ever change the way extract operates! Additionally, the target post-deinstall is invalid and is not run by the ports infrastructure.

Now that what goes on when the user types make install is better understood, let us go through the recommended steps to create the perfect port.

4.2. Getting the Original Sources

Get the original sources (normally) as a compressed tarball (foo.tar.gz or foo.tar.bz2) and copy it into DISTDIR. Always use mainstream sources when and where possible.

Set the variable MASTER_SITES to reflect where the original tarball resides. Shorthand definitions exist for most mainstream sites in bsd.sites.mk. Please use these sites-and the associated definitions-if at all possible, to help avoid the problem of having the same information repeated over again many times in the source base. As these sites tend to change over time, this becomes a maintenance nightmare for everyone involved. See MASTER_SITES for details.

If there is no FTP/HTTP site that is well-connected to the net, or can only find sites that have irritatingly non-standard formats, put a copy on a reliable FTP or HTTP server (for example, a home page).

If a convenient and reliable place to put the distfile cannot be found, we can "house" it ourselves on ftp.FreeBSD.org; however, this is the least-preferred solution. The distfile must be placed into ~/public_distfiles/ of someone’s freefall account. Ask the person who commits the port to do this. This person will also set MASTER_SITES to LOCAL/username where username is their FreeBSD cluster login.

If the port’s distfile changes all the time without any kind of version update by the author, consider putting the distfile on a home page and listing it as the first MASTER_SITES. Try to talk the port author out of doing this; it really does help to establish some kind of source code control. Hosting a specific version will prevent users from getting checksum mismatch errors, and also reduce the workload of maintainers of our FTP site. Also, if there is only one master site for the port, it is recommended to house a backup on a home page and list it as the second MASTER_SITES.

If the port requires additional patches that are available on the Internet, fetch them too and put them in DISTDIR. Do not worry if they come from a site other than where the main source tarball comes, we have a way to handle these situations (see the description of PATCHFILES below).

4.3. Modifying the Port

Unpack a copy of the tarball in a private directory and make whatever changes are necessary to get the port to compile properly under the current version of FreeBSD. Keep careful track of steps, as they will be needed to automate the process shortly. Everything, including the deletion, addition, or modification of files has to be doable using an automated script or patch file when the port is finished.

If the port requires significant user interaction/customization to compile or install, take a look at one of Larry Wall’s classic Configure scripts and perhaps do something similar. The goal of the new ports collection is to make each port as "plug-and-play" as possible for the end-user while using a minimum of disk space.

Unless explicitly stated, patch files, scripts, and other files created and contributed to the FreeBSD ports collection are assumed to be covered by the standard BSD copyright conditions.

4.4. Patching

In the preparation of the port, files that have been added or changed can be recorded with diff(1) for later feeding to patch(1). Doing this with a typical file involves saving a copy of the original file before making any changes using a .orig suffix.

% cp file file.orig

After all changes have been made, cd back to the port directory. Use make makepatch to generate updated patch files in the files directory.

Use BINARY_ALIAS to substitute hardcoded commands during the build and avoid patching build files. See Use BINARY_ALIAS to Rename Commands Instead of Patching the Build for more information.

4.4.1. General Rules for Patching

Patch files are stored in PATCHDIR, usually files/, from where they will be automatically applied. All patches must be relative to WRKSRC. Typically WRKSRC is a subdirectory of WRKDIR, the directory where the distfile is extracted. Use make -V WRKSRC to see the actual path. The patch names are to follow these rules:

Avoid having more than one patch modify the same file. For example, having both patch-foobar.c and patch-foobar.c2 making changes to ${WRKSRC}/foobar.c makes them fragile and difficult to debug.
When creating names for patch files, replace each underscore (_) with two underscores (__) and each slash (/) with one underscore (_). For example, to patch a file named src/freeglut_joystick.c, name the corresponding patch patch-src_freeglut__joystick.c. Do not name patches like patch-aa or patch-ab. Always use the path and file name in patch names. Using make makepatch automatically generates the correct names.
A patch may modify multiple files if the changes are related and the patch is named appropriately. For example, patch-add-missing-stdlib.h.
Only use characters [-+._a-zA-Z0-9] for naming patches. In particular, do not use :: as a path separator, use _ instead.

Minimize the amount of non-functional whitespace changes in patches. It is common in the Open Source world for projects to share large amounts of a code base, but obey different style and indenting rules. When taking a working piece of functionality from one project to fix similar areas in another, please be careful: the resulting patch may be full of non-functional changes. It not only increases the size of the ports repository but makes it hard to find out what exactly caused the problem and what was changed at all.

If a file must be deleted, do it in the post-extract target rather than as part of the patch.

4.4.2. Manual Patch Generation

Manual patch creation is usually not necessary. Automatic patch generation as described earlier in this section is the preferred method. However, manual patching may be required occasionally.

Patches are saved into files named patch-* where * indicates the pathname of the file that is patched, such as patch-Imakefile or patch-src-config.h. Patches with file names which do not start with patch- will not be applied automatically.

After the file has been modified, diff(1) is used to record the differences between the original and the modified version. -u causes diff(1) to produce "unified" diffs, the preferred form.

% diff -u file.orig file > patch-pathname-file

When generating patches for new, added files, -N is used to tell diff(1) to treat the non-existent original file as if it existed but was empty:

% diff -u -N newfile.orig newfile > patch-pathname-newfile

Using the recurse (-r) option to diff(1) to generate patches is fine, but please look at the resulting patches to make sure there is no unnecessary junk in there. In particular, diffs between two backup files, Makefiles when the port uses Imake or GNU configure, etc., are unnecessary and have to be deleted. If it was necessary to edit configure.in and run autoconf to regenerate configure, do not take the diffs of configure (it often grows to a few thousand lines!). Instead, define USES=autoreconf and take the diffs of configure.in.

4.4.3. Simple Automatic Replacements

Simple replacements can be performed directly from the port Makefile using the in-place mode of sed(1). This is useful when changes use the value of a variable:

post-patch:
	@${REINPLACE_CMD} -e 's|/usr/local|${PREFIX}|g' ${WRKSRC}/Makefile

Only use sed(1) to replace variable content. You must use patch files instead of sed(1) to replace static content.

Quite often, software being ported uses the CR/LF convention in source files. This may cause problems with further patching, compiler warnings, or script execution (like /bin/sh^M not found.) To quickly convert all files from CR/LF to just LF, add this entry to the port Makefile:

USES=	dos2unix

A list of specific files to convert can be given:

USES=	dos2unix
DOS2UNIX_FILES=	util.c util.h

Use DOS2UNIX_REGEX to convert a group of files across subdirectories. Its argument is a find(1)-compatible regular expression. More on the format is in re_format(7). This option is useful for converting all files of a given extension. For example, convert all source code files, leaving binary files intact:

USES=	dos2unix
DOS2UNIX_REGEX=	.*\.([ch]|cpp)

A similar option is DOS2UNIX_GLOB, which runs find for each element listed in it.

USES=	dos2unix
DOS2UNIX_GLOB=	*.c *.cpp *.h

The base directory for the conversion can be set. This is useful when there are multiple distfiles and several contain files which require line-ending conversion.

USES=	dos2unix
DOS2UNIX_WRKSRC=	${WRKDIR}

4.4.4. Patching Conditionally

Some ports need patches that are only applied for specific FreeBSD versions or when a particular option is enabled or disabled. Conditional patches are specified by placing the full paths to the patch files in EXTRA_PATCHES. Conditional patch file names usually start with extra- although this is not necessary. However, their file names must not start with patch-. If they do, they are applied unconditionally by the framework which is undesired for conditional patches.

Example 2. Applying a Patch for a Specific FreeBSD Version

.include <bsd.port.options.mk>

# Patch in the iconv const qualifier before this
.if ${OPSYS} == FreeBSD && ${OSVERSION} < 1100069
EXTRA_PATCHES=	${PATCHDIR}/extra-patch-fbsd10
.endif

.include <bsd.port.mk>

Example 3. Optionally Applying a Patch

When an option requires a patch, use opt_EXTRA_PATCHES and opt_EXTRA_PATCHES_OFF to make the patch conditional on the opt option. See Generic Variables Replacement for more information.

OPTIONS_DEFINE=	  FOO BAR
FOO_EXTRA_PATCHES=  ${PATCHDIR}/extra-patch-foo
BAR_EXTRA_PATCHES_OFF=	${PATCHDIR}/extra-patch-bar.c \
		${PATCHDIR}/extra-patch-bar.h

Example 4. Using EXTRA_PATCHES With a Directory

Sometimes, there are many patches that are needed for a feature, in this case, it is possible to point EXTRA_PATCHES to a directory, and it will automatically apply all files named patch-* in it.

Create a subdirectory in ${PATCHDIR}, and move the patches in it. For example:

% ls -l files/foo-patches
-rw-r--r--  1 root  wheel    350 Jan 16 01:27 patch-Makefile.in
-rw-r--r--  1 root  wheel   3084 Jan 18 15:37 patch-configure.ac

Then add this to the Makefile:

OPTIONS_DEFINE=	FOO
FOO_EXTRA_PATCHES=	${PATCHDIR}/foo-patches

The framework will then use all the files named patch-* in that directory.

4.5. Configuring

Include any additional customization commands in the configure script and save it in the scripts subdirectory. As mentioned above, it is also possible do this with Makefile targets and/or scripts with the name pre-configure or post-configure.

4.6. Handling User Input

If the port requires user input to build, configure, or install, set IS_INTERACTIVE in the Makefile. This will allow "overnight builds" to skip it. If the user sets the variable BATCH in their environment (and if the user sets the variable INTERACTIVE, then only those ports requiring interaction are built). This will save a lot of wasted time on the set of machines that continually build ports (see below).

It is also recommended that if there are reasonable default answers to the questions, PACKAGE_BUILDING be used to turn off the interactive script when it is set. This will allow us to build the packages for CDROMs and FTP.

Chapter 5. Configuring the Makefile

Configuring the Makefile is pretty simple, and again we suggest looking at existing examples before starting. Also, there is a sample Makefile in this handbook, so take a look and please follow the ordering of variables and sections in that template to make the port easier for others to read.

Consider these problems in sequence during the design of the new Makefile:

5.1. The Original Source

Does it live in DISTDIR as a standard gzipped tarball named something like foozolix-1.2.tar.gz? If so, go on to the next step. If not, the distribution file format might require overriding one or more of DISTVERSION, DISTNAME, EXTRACT_CMD, EXTRACT_BEFORE_ARGS, EXTRACT_AFTER_ARGS, EXTRACT_SUFX, or DISTFILES.

In the worst case, create a custom do-extract target to override the default. This is rarely, if ever, necessary.

5.2. Naming

The first part of the port’s Makefile names the port, describes its version number, and lists it in the correct category.

5.2.1. `PORTNAME`

Set PORTNAME to the base name of the software. It is used as the base for the FreeBSD package, and for DISTNAME.

The package name must be unique across the entire ports tree. Make sure that the PORTNAME is not already in use by an existing port, and that no other port already has the same PKGBASE. If the name has already been used, add either PKGNAMEPREFIX or PKGNAMESUFFIX.

5.2.2. Versions, `DISTVERSION` or `PORTVERSION`

Set DISTVERSION to the version number of the software.

PORTVERSION is the version used for the FreeBSD package. It will be automatically derived from DISTVERSION to be compatible with FreeBSD’s package versioning scheme. If the version contains letters, it might be needed to set PORTVERSION and not DISTVERSION.

Only one of PORTVERSION and DISTVERSION can be set at a time.

From time to time, some software will use a version scheme that is not compatible with how DISTVERSION translates in PORTVERSION.

When updating a port, it is possible to use pkg-version(8)'s -t argument to check if the new version is greater or lesser than before. See Using pkg-version\(8] to Compare Versions).

Example 5. Using pkg-version(8) to Compare Versions

pkg version -t takes two versions as arguments, it will respond with <, = or > if the first version is less, equal, or more than the second version, respectively.

% pkg version -t 1.2 1.3
< (1)
% pkg version -t 1.2 1.2
= (2)
% pkg version -t 1.2 1.2.0
= (3)
% pkg version -t 1.2 1.2.p1
> (4)
% pkg version -t 1.2.a1 1.2.b1
< (5)
% pkg version -t 1.2 1.2p1
< (6)

1	`1.2` is before `1.3`.
2	`1.2` and `1.2` are equal as they have the same version.
3	`1.2` and `1.2.0` are equal as nothing equals zero.
4	`1.2` is after `1.2.p1` as `.p1`, think "pre-release 1".
5	`1.2.a1` is before `1.2.b1`, think "alpha" and "beta", and `a` is before `b`.
6	`1.2` is before `1.2p1` as `2p1`, think "2, patch level 1" which is a version after any `2.X` but before `3`.

In here, the a, b, and p are used as if meaning "alpha", "beta" or "pre-release" and "patch level", but they are only letters and are sorted alphabetically, so any letter can be used, and they will be sorted appropriately.

Table 1. Examples of `DISTVERSION` and the Derived `PORTVERSION`
DISTVERSION	PORTVERSION
0.7.1d	0.7.1.d
10Alpha3	10.a3
3Beta7-pre2	3.b7.p2
8:f_17	8f.17

Example 6. Using DISTVERSION

When the version only contains numbers separated by dots, dashes or underscores, use DISTVERSION.

PORTNAME=   nekoto
DISTVERSION=	1.2-4

It will generate a PORTVERSION of 1.2.4.

Example 7. Using DISTVERSION When the Version Starts with a Letter or a Prefix

When the version starts or ends with a letter, or a prefix or a suffix that is not part of the version, use DISTVERSIONPREFIX, DISTVERSION, and DISTVERSIONSUFFIX.

If the version is v1.2-4:

PORTNAME=   nekoto
DISTVERSIONPREFIX=  v
DISTVERSION=	1_2_4

Some of the time, projects using GitHub will use their name in their versions. For example, the version could be nekoto-1.2-4:

PORTNAME=   nekoto
DISTVERSIONPREFIX=  nekoto-
DISTVERSION=	1.2_4

Those projects also sometimes use some string at the end of the version, for example, 1.2-4_RELEASE:

PORTNAME=   nekoto
DISTVERSION=	1.2-4
DISTVERSIONSUFFIX=  _RELEASE

Or they do both, for example, nekoto-1.2-4_RELEASE:

PORTNAME=   nekoto
DISTVERSIONPREFIX=  nekoto-
DISTVERSION=	1.2-4
DISTVERSIONSUFFIX=  _RELEASE

DISTVERSIONPREFIX and DISTVERSIONSUFFIX will not be used while constructing PORTVERSION, but only used in DISTNAME.

All will generate a PORTVERSION of 1.2.4.

Example 8. Using DISTVERSION When the Version Contains Letters Meaning "alpha", "beta", or "pre-release"

When the version contains numbers separated by dots, dashes or underscores, and letters are used to mean "alpha", "beta" or "pre-release", which is, before the version without the letters, use DISTVERSION.

PORTNAME=   nekoto
DISTVERSION=	1.2-pre4

PORTNAME=   nekoto
DISTVERSION=	1.2p4

Both will generate a PORTVERSION of 1.2.p4 which is before than 1.2. pkg-version(8) can be used to check that fact:

% pkg version -t 1.2.p4 1.2
<

Example 9. Not Using DISTVERSION When the Version Contains Letters Meaning "Patch Level"

When the version contains letters that are not meant as "alpha", "beta", or "pre", but more in a "patch level", and meaning after the version without the letters, use PORTVERSION.

PORTNAME=   nekoto
PORTVERSION=	1.2p4

In this case, using DISTVERSION is not possible because it would generate a version of 1.2.p4 which would be before 1.2 and not after. pkg-version(8) will verify this:

% pkg version -t 1.2 1.2.p4
> (1)
% pkg version -t 1.2 1.2p4
< (2)

1	`1.2` is after `1.2.p4`, which is wrong in this case.
2	`1.2` is before `1.2p4`, which is what was needed.

For some more advanced examples of setting PORTVERSION, when the software’s versioning is really not compatible with FreeBSD’s, or DISTNAME when the distribution file does not contain the version itself, see DISTNAME.

5.2.3. `PORTREVISION` and `PORTEPOCH`

5.2.3.1. `PORTREVISION`

PORTREVISION is a monotonically increasing value which is reset to 0 with every increase of DISTVERSION, typically every time there is a new official vendor release. If PORTREVISION is non-zero, the value is appended to the package name. Changes to PORTREVISION are used by automated tools like pkg-version(8) to determine that a new package is available.

PORTREVISION must be increased each time a change is made to the port that changes the generated package in any way. That includes changes that only affect a package built with non-default options.

Examples of when PORTREVISION must be bumped:

Addition of patches to correct security vulnerabilities, bugs, or to add new functionality to the port.
Changes to the port Makefile to enable or disable compile-time options in the package.
Changes in the packing list or the install-time behavior of the package. For example, a change to a script which generates initial data for the package, like ssh(1) host keys.
Version bump of a port’s shared library dependency (in this case, someone trying to install the old package after installing a newer version of the dependency will fail since it will look for the old libfoo.x instead of libfoo.(x+1)).
Silent changes to the port distfile which have significant functional differences. For example, changes to the distfile requiring a correction to distinfo with no corresponding change to DISTVERSION, where a diff -ru of the old and new versions shows non-trivial changes to the code.
Changes to MAINTAINER.

Examples of changes which do not require a PORTREVISION bump:

Style changes to the port skeleton with no functional change to what appears in the resulting package.
Changes to MASTER_SITES or other functional changes to the port which do not affect the resulting package.
Trivial patches to the distfile such as correction of typos, which are not important enough that users of the package have to go to the trouble of upgrading.
Build fixes which cause a package to become compilable where it was previously failing. As long as the changes do not introduce any functional change on any other platforms on which the port did previously build. Since PORTREVISION reflects the content of the package, if the package was not previously buildable then there is no need to increase PORTREVISION to mark a change.

A rule of thumb is to decide whether a change committed to a port is something which some people would benefit from having. Either because of an enhancement, fix, or by virtue that the new package will actually work at all. Then weigh that against that fact that it will cause everyone who regularly updates their ports tree to be compelled to update. If yes, PORTREVISION must be bumped.

People using binary packages will never see the update if PORTREVISION is not bumped. Without increasing PORTREVISION, the package builders have no way to detect the change and thus, will not rebuild the package.

5.2.3.2. `PORTEPOCH`

From time to time a software vendor or FreeBSD porter will do something silly and release a version of their software which is actually numerically less than the previous version. An example of this is a port which goes from foo-20000801 to foo-1.0 (the former will be incorrectly treated as a newer version since 20000801 is a numerically greater value than 1).

The results of version number comparisons are not always obvious. pkg version (see pkg-version(8)) can be used to test the comparison of two version number strings. For example:

% pkg version -t 0.031 0.29
>

The > output indicates that version 0.031 is considered greater than version 0.29, which may not have been obvious to the porter.

In situations such as this, PORTEPOCH must be increased. If PORTEPOCH is nonzero it is appended to the package name as described in section 0 above. PORTEPOCH must never be decreased or reset to zero, because that would cause comparison to a package from an earlier epoch to fail. For example, the package would not be detected as out of date. The new version number, 1.0,1 in the above example, is still numerically less than the previous version, 20000801, but the ,1 suffix is treated specially by automated tools and found to be greater than the implied suffix ,0 on the earlier package.

Dropping or resetting PORTEPOCH incorrectly leads to no end of grief. If the discussion above was not clear enough, please consult the FreeBSD ports mailing list.

It is expected that PORTEPOCH will not be used for the majority of ports, and that sensible use of DISTVERSION, or that use PORTVERSION carefully, can often preempt it becoming necessary if a future release of the software changes the version structure. However, care is needed by FreeBSD porters when a vendor release is made without an official version number - such as a code "snapshot" release. The temptation is to label the release with the release date, which will cause problems as in the example above when a new "official" release is made.

For example, if a snapshot release is made on the date 20000917, and the previous version of the software was version 1.2, do not use 20000917 for DISTVERSION. The correct way is a DISTVERSION of 1.2.20000917, or similar, so that the succeeding release, say 1.3, is still a numerically greater value.

5.2.3.3. Example of `PORTREVISION` and `PORTEPOCH` Usage

The gtkmumble port, version 0.10, is committed to the ports collection:

PORTNAME=	gtkmumble
DISTVERSION=	0.10

PKGNAME becomes gtkmumble-0.10.

A security hole is discovered which requires a local FreeBSD patch. PORTREVISION is bumped accordingly.

PORTNAME=	gtkmumble
DISTVERSION=	0.10
PORTREVISION=	1

PKGNAME becomes gtkmumble-0.10_1

A new version is released by the vendor, numbered 0.2 (it turns out the author actually intended 0.10 to actually mean 0.1.0, not "what comes after 0.9" - oops, too late now). Since the new minor version 2 is numerically less than the previous version 10, PORTEPOCH must be bumped to manually force the new package to be detected as "newer". Since it is a new vendor release of the code, PORTREVISION is reset to 0 (or removed from the Makefile).

PORTNAME=	gtkmumble
DISTVERSION=	0.2
PORTEPOCH=	1

PKGNAME becomes gtkmumble-0.2,1

The next release is 0.3. Since PORTEPOCH never decreases, the version variables are now:

PORTNAME=	gtkmumble
DISTVERSION=	0.3
PORTEPOCH=	1

PKGNAME becomes gtkmumble-0.3,1

If PORTEPOCH were reset to 0 with this upgrade, someone who had installed the gtkmumble-0.10_1 package would not detect the gtkmumble-0.3 package as newer, since 3 is still numerically less than 10. Remember, this is the whole point of PORTEPOCH in the first place.

5.2.4. `PKGNAMEPREFIX` and `PKGNAMESUFFIX`

Two optional variables, PKGNAMEPREFIX and PKGNAMESUFFIX, are combined with PORTNAME and PORTVERSION to form PKGNAME as ${PKGNAMEPREFIX}${PORTNAME}${PKGNAMESUFFIX}-${PORTVERSION}. Make sure this conforms to our guidelines for a good package name. In particular, the use of a hyphen (-) in PORTVERSION is not allowed. Also, if the package name has the language- or the -compiled.specifics part (see below), use PKGNAMEPREFIX and PKGNAMESUFFIX, respectively. Do not make them part of PORTNAME.

5.2.5. Package Naming Conventions

These are the conventions to follow when naming packages. This is to make the package directory easy to scan, as there are already thousands of packages and users are going to turn away if they hurt their eyes!

Package names take the form of language_region-name-compiled.specifics-version.numbers.

The package name is defined as ${PKGNAMEPREFIX}${PORTNAME}${PKGNAMESUFFIX}-${PORTVERSION}. Make sure to set the variables to conform to that format.

language_region-: FreeBSD strives to support the native language of its users. The language- part is a two letter abbreviation of the natural language defined by ISO-639 when the port is specific to a certain language. Examples are ja for Japanese, ru for Russian, vi for Vietnamese, zh for Chinese, ko for Korean and de for German.
If the port is specific to a certain region within the language area, add the two letter country code as well. Examples are en_US for US English and fr_CH for Swiss French.
The language- part is set in PKGNAMEPREFIX.

name: Make sure that the port’s name and version are clearly separated and placed into PORTNAME and DISTVERSION. The only reason for PORTNAME to contain a version part is if the upstream distribution is really named that way, as in the textproc/libxml2 or japanese/kinput2-freewnn ports. Otherwise, PORTNAME cannot contain any version-specific information. It is quite normal for several ports to have the same PORTNAME, as the www/apache* ports do; in that case, different versions (and different index entries) are distinguished by PKGNAMEPREFIX and PKGNAMESUFFIX values.
There is a tradition of naming Perl 5 modules by prepending p5- and converting the double-colon separator to a hyphen. For example, the Data::Dumper module becomes p5-Data-Dumper.

-compiled.specifics: If the port can be built with different hardcoded defaults (usually part of the directory name in a family of ports), the -compiled.specifics part states the compiled-in defaults. The hyphen is optional. Examples are paper size and font units.
The -compiled.specifics part is set in PKGNAMESUFFIX.

-version.numbers: The version string follows a dash (-) and is a period-separated list of integers and single lowercase alphabetics. In particular, it is not permissible to have another dash inside the version string. The only exception is the string pl (meaning "patchlevel"), which can be used only when there are no major and minor version numbers in the software. If the software version has strings like "alpha", "beta", "rc", or "pre", take the first letter and put it immediately after a period. If the version string continues after those names, the numbers follow the single alphabet without an extra period between them (for example, 1.0b2).
The idea is to make it easier to sort ports by looking at the version string. In particular, make sure version number components are always delimited by a period, and if the date is part of the string, use the dyyyy.mm.dd format, not dd.mm.yyyy or the non-Y2K compliant yy.mm.dd format. It is important to prefix the version with a letter, here d (for date), in case a release with an actual version number is made, which would be numerically less than yyyy.

Package name must be unique among all of the ports tree, check that there is not already a port with the same PORTNAME and if there is add one of PKGNAMEPREFIX or PKGNAMESUFFIX.

Here are some (real) examples on how to convert the name as called by the software authors to a suitable package name, for each line, only one of DISTVERSION or PORTVERSION is set in, depending on which would be used in the port’s Makefile:

Table 2. Package Naming Examples
Distribution Name	PKGNAMEPREFIX	PORTNAME	PKGNAMESUFFIX	DISTVERSION	PORTVERSION	Reason or comment
mule-2.2.2	(empty)	mule	(empty)	2.2.2		No changes required
mule-1.0.1	(empty)	mule	1	1.0.1		This is version 1 of mule, and version 2 already exists
EmiClock-1.0.2	(empty)	emiclock	(empty)	1.0.2		No uppercase names for single programs
rdist-1.3alpha	(empty)	rdist	(empty)	1.3alpha		Version will be `1.3.a`
es-0.9-beta1	(empty)	es	(empty)	0.9-beta1		Version will be `0.9.b1`
mailman-2.0rc3	(empty)	mailman	(empty)	2.0rc3		Version will be `2.0.r3`
v3.3beta021.src	(empty)	tiff	(empty)		3.3	What the heck was that anyway?
tvtwm	(empty)	tvtwm	(empty)		p11	No version in the filename, use what upstream says it is
piewm	(empty)	piewm	(empty)	1.0		No version in the filename, use what upstream says it is
xvgr-2.10pl1	(empty)	xvgr	(empty)		2.10.pl1	In that case, `pl1` means patch level, so using DISTVERSION is not possible.
gawk-2.15.6	ja-	gawk	(empty)	2.15.6		Japanese language version
psutils-1.13	(empty)	psutils	-letter	1.13		Paper size hardcoded at package build time
pkfonts	(empty)	pkfonts	300	1.0		Package for 300dpi fonts

If there is absolutely no trace of version information in the original source and it is unlikely that the original author will ever release another version, just set the version string to 1.0 (like the piewm example above). Otherwise, ask the original author or use the date string the source file was released on (dyyyy.mm.dd, or dyyyymmdd) as the version.

Use any letter. Here, d here stands for date, if the source is a Git repository, g followed by the commit date is commonly used, using s for snapshot is also common.

5.3. Categorization

5.3.1. `CATEGORIES`

When a package is created, it is put under /usr/ports/packages/All and links are made from one or more subdirectories of /usr/ports/packages. The names of these subdirectories are specified by the variable CATEGORIES. It is intended to make life easier for the user when he is wading through the pile of packages on the FTP site or the CDROM. Please take a look at the current list of categories and pick the ones that are suitable for the port.

This list also determines where in the ports tree the port is imported. If there is more than one category here, the port files must be put in the subdirectory with the name of the first category. See below for more discussion about how to pick the right categories.

5.3.2. Current List of Categories

Here is the current list of port categories. Those marked with an asterisk (*) are virtual categories-those that do not have a corresponding subdirectory in the ports tree. They are only used as secondary categories, and only for search purposes.

For non-virtual categories, there is a one-line description in COMMENT in that subdirectory’s Makefile.

5.3.3. Choosing the Right Category

As many of the categories overlap, choosing which of the categories will be the primary category of the port can be tedious. There are several rules that govern this issue. Here is the list of priorities, in decreasing order of precedence:

The first category must be a physical category (see above). This is necessary to make the packaging work. Virtual categories and physical categories may be intermixed after that.
Language specific categories always come first. For example, if the port installs Japanese X11 fonts, then the CATEGORIES line would read japanese x11-fonts.
Specific categories are listed before less-specific ones. For instance, an HTML editor is listed as www editors, not the other way around. Also, do not list net when the port belongs to any of irc, mail, news, security, or www, as net is included implicitly.
x11 is used as a secondary category only when the primary category is a natural language. In particular, do not put x11 in the category line for X applications.
Emacs modes are placed in the same ports category as the application supported by the mode, not in editors. For example, an Emacs mode to edit source files of some programming language goes into lang.
Ports installing loadable kernel modules also have the virtual category kld in their CATEGORIES line. This is one of the things handled automatically by adding USES=kmod.
misc does not appear with any other non-virtual category. If there is misc with something else in CATEGORIES, that means misc can safely be deleted and the port placed only in the other subdirectory.
If the port truly does not belong anywhere else, put it in misc.

If the category is not clearly defined, please put a comment to that effect in the port submission in the bug database so we can discuss it before we import it. As a committer, send a note to the FreeBSD ports mailing list so we can discuss it first. Too often, new ports are imported to the wrong category only to be moved right away.

5.3.4. Proposing a New Category

As the Ports Collection has grown over time, various new categories have been introduced. New categories can either be virtual categories-those that do not have a corresponding subdirectory in the ports tree- or physical categories-those that do. This section discusses the issues involved in creating a new physical category. Read it thoroughly before proposing a new one.

Our existing practice has been to avoid creating a new physical category unless either a large number of ports would logically belong to it, or the ports that would belong to it are a logically distinct group that is of limited general interest (for instance, categories related to spoken human languages), or preferably both.

The rationale for this is that such a change creates a fair amount of work for both the committers and also for all users who track changes to the Ports Collection. In addition, proposed category changes just naturally seem to attract controversy. (Perhaps this is because there is no clear consensus on when a category is "too big", nor whether categories should lend themselves to browsing (and thus what number of categories would be an ideal number), and so forth.)

Here is the procedure:

Propose the new category on FreeBSD ports mailing list. Include a detailed rationale for the new category, including why the existing categories are not sufficient, and the list of existing ports proposed to move. (If there are new ports pending in Bugzilla that would fit this category, list them too.) If you are the maintainer and/or submitter, respectively, mention that as it may help the case.
Participate in the discussion.
If it seems that there is support for the idea, file a PR which includes both the rationale and the list of existing ports that need to be moved. Ideally, this PR would also include these patches:
- Makefiles for the new ports once they are repocopied
- Makefile for the new category
- Makefile for the old ports' categories
- Makefiles for ports that depend on the old ports
- (for extra credit, include the other files that have to change, as per the procedure in the Committer’s Guide.)
Since it affects the ports infrastructure and involves moving and patching many ports but also possibly running regression tests on the build cluster, assign the PR to the Ports Management Team <portmgr@FreeBSD.org>.
If that PR is approved, a committer will need to follow the rest of the procedure that is outlined in the Committer’s Guide.

Proposing a new virtual category is similar to the above but much less involved, since no ports will actually have to move. In this case, the only patches to include in the PR would be those to add the new category to CATEGORIES of the affected ports.

5.3.5. Proposing Reorganizing All the Categories

Occasionally someone proposes reorganizing the categories with either a 2-level structure, or some other kind of keyword structure. To date, nothing has come of any of these proposals because, while they are very easy to make, the effort involved to retrofit the entire existing ports collection with any kind of reorganization is daunting to say the very least. Please read the history of these proposals in the mailing list archives before posting this idea. Furthermore, be prepared to be challenged to offer a working prototype.

5.4. The Distribution Files

The second part of the Makefile describes the files that must be downloaded to build the port, and where they can be downloaded.

5.4.1. `DISTNAME`

DISTNAME is the name of the port as called by the authors of the software. DISTNAME defaults to ${PORTNAME}-${DISTVERSIONPREFIX}${DISTVERSION}${DISTVERSIONSUFFIX}, and if not set, DISTVERSION defaults to ${PORTVERSION} so override DISTNAME only if necessary. DISTNAME is only used in two places. First, the distribution file list (DISTFILES) defaults to ${DISTNAME}${EXTRACT_SUFX}. Second, the distribution file is expected to extract into a subdirectory named WRKSRC, which defaults to work/${DISTNAME}.

Some vendor’s distribution names which do not fit into the ${PORTNAME}-${PORTVERSION}-scheme can be handled automatically by setting DISTVERSIONPREFIX, DISTVERSION, and DISTVERSIONSUFFIX. PORTVERSION will be derived from DISTVERSION automatically.

Only one of PORTVERSION and DISTVERSION can be set at a time. If DISTVERSION does not derive a correct PORTVERSION, do not use DISTVERSION.

If the upstream version scheme can be derived into a ports-compatible version scheme, set some variable to the upstream version, do not use DISTVERSION as the variable name. Set PORTVERSION to the computed version based on the variable you created, and set DISTNAME accordingly.

If the upstream version scheme cannot easily be coerced into a ports-compatible value, set PORTVERSION to a sensible value, and set DISTNAME with PORTNAME with the verbatim upstream version.

Example 10. Deriving PORTVERSION Manually

BIND9 uses a version scheme that is not compatible with the ports versions (it has - in its versions) and cannot be derived using DISTVERSION because after the 9.9.9 release, it will release a "patchlevels" in the form of 9.9.9-P1. DISTVERSION would translate that into 9.9.9.p1, which, in the ports versioning scheme means 9.9.9 pre-release 1, which is before 9.9.9 and not after. So PORTVERSION is manually derived from an ISCVERSION variable to output 9.9.9p1.

The order into which the ports framework, and pkg, will sort versions is checked using the -t argument of pkg-version(8):

% pkg version -t 9.9.9 9.9.9.p1
> (1)
% pkg version -t 9.9.9 9.9.9p1
< (2)

1	The `>` sign means that the first argument passed to `-t` is greater than the second argument. `9.9.9` is after `9.9.9.p1`.
2	The `<` sign means that the first argument passed to `-t` is less than the second argument. `9.9.9` is before `9.9.9p1`.

In the port Makefile, for example dns/bind99, it is achieved by:

PORTNAME=	bind
PORTVERSION=	${ISCVERSION:S/-P/P/:S/b/.b/:S/a/.a/:S/rc/.rc/}
CATEGORIES=	dns net
MASTER_SITES=	ISC/bind9/${ISCVERSION}
PKGNAMESUFFIX=	99
DISTNAME=	${PORTNAME}-${ISCVERSION}

MAINTAINER=	mat@FreeBSD.org
COMMENT=	BIND DNS suite with updated DNSSEC and DNS64
WWW=		https://www.isc.org/bind/

LICENSE=	ISCL

# ISC releases things like 9.8.0-P1 or 9.8.1rc1, which our versioning does not like
ISCVERSION=	9.9.9-P6

Define upstream version in ISCVERSION, with a comment saying why it is needed. Use ISCVERSION to get a ports-compatible PORTVERSION. Use ISCVERSION directly to get the correct URL for fetching the distribution file. Use ISCVERSION directly to name the distribution file.

Example 11. Derive DISTNAME from PORTVERSION

From time to time, the distribution file name has little or no relation to the version of the software.

In comms/kermit, only the last element of the version is present in the distribution file:

PORTNAME=	kermit
PORTVERSION=	9.0.304
CATEGORIES=	comms ftp net
MASTER_SITES=	ftp://ftp.kermitproject.org/kermit/test/tar/
DISTNAME=	cku${PORTVERSION:E}-dev20

The :E make(1) modifier returns the suffix of the variable, in this case, 304. The distribution file is correctly generated as cku304-dev20.tar.gz.

Example 12. Exotic Case 1

Sometimes, there is no relation between the software name, its version, and the distribution file it is distributed in.

From audio/libworkman:

PORTNAME=       libworkman
PORTVERSION=    1.4
CATEGORIES=     audio
MASTER_SITES=   LOCAL/jim
DISTNAME=       ${PORTNAME}-1999-06-20

Example 13. Exotic Case 2

In comms/librs232, the distribution file is not versioned, so using DIST_SUBDIR is needed:

PORTNAME=       librs232
PORTVERSION=    20160710
CATEGORIES=     comms
MASTER_SITES=   http://www.teuniz.net/RS-232/
DISTNAME=       RS-232
DIST_SUBDIR=	${PORTNAME}-${PORTVERSION}

PKGNAMEPREFIX and PKGNAMESUFFIX do not affect DISTNAME. Also note that if WRKSRC is equal to ${WRKDIR}/${DISTNAME} while the original source archive is named something other than ${PORTNAME}-${PORTVERSION}${EXTRACT_SUFX}, leave DISTNAME alone- defining only DISTFILES is easier than both DISTNAME and WRKSRC (and possibly EXTRACT_SUFX).

5.4.2. `MASTER_SITES`

Record the directory part of the FTP/HTTP-URL pointing at the original tarball in MASTER_SITES. Do not forget the trailing slash (/)!

The make macros will try to use this specification for grabbing the distribution file with FETCH if they cannot find it already on the system.

It is recommended that multiple sites are included on this list, preferably from different continents. This will safeguard against wide-area network problems.

MASTER_SITES must not be blank. It must point to the actual site hosting the distribution files. It cannot point to web archives, or the FreeBSD distribution files cache sites. The only exception to this rule is ports that do not have any distribution files. For example, meta-ports do not have any distribution files, so MASTER_SITES does not need to be set.

5.4.2.1. Using `MASTER_SITE_*` Variables

Shortcut abbreviations are available for popular archives like SourceForge (SOURCEFORGE), GNU (GNU), or Perl CPAN (PERL_CPAN). MASTER_SITES can use them directly:

MASTER_SITES=	GNU/make

The older expanded format still works, but all ports have been converted to the compact format. The expanded format looks like this:

MASTER_SITES=		${MASTER_SITE_GNU}
MASTER_SITE_SUBDIR=	make

These values and variables are defined in Mk/bsd.sites.mk. New entries are added often, so make sure to check the latest version of this file before submitting a port.

For any MASTER_SITE_FOO variable, the shorthand FOO can be used. For example, use:

MASTER_SITES=	FOO

If MASTER_SITE_SUBDIR is needed, use this:

MASTER_SITES=	FOO/bar

Some MASTER_SITE_* names are quite long, and for ease of use, shortcuts have been defined:

Table 3. Shortcuts for `MASTER_SITE_*` Macros
Macro	Shortcut
`PERL_CPAN`	`CPAN`
`GITHUB`	`GH`
`GITHUB_CLOUD`	`GHC`
`LIBREOFFICE_DEV`	`LODEV`
`NETLIB`	`NL`
`RUBYGEMS`	`RG`
`SOURCEFORGE`	`SF`

5.4.2.2. Magic MASTER_SITES Macros

Several "magic" macros exist for popular sites with a predictable directory structure. For these, just use the abbreviation and the system will choose a subdirectory automatically. For a port named Stardict, of version 1.2.3, and hosted on SourceForge, adding this line:

MASTER_SITES=	SF

infers a subdirectory named /project/stardict/stardict/1.2.3. If the inferred directory is incorrect, it can be overridden:

MASTER_SITES=	SF/stardict/WyabdcRealPeopleTTS/${PORTVERSION}

This can also be written as

MASTER_SITES=	SF
MASTER_SITE_SUBDIR=	stardict/WyabdcRealPeopleTTS/${PORTVERSION}

Table 4. Magic `MASTER_SITES` Macros
Macro	Assumed subdirectory

`SF`	`${PORTNAME:tl}/${PORTNAME:tl}/${PORTVERSION}`

5.4.3. `USE_GITHUB`

If the distribution file comes from a specific commit or tag on GitHub for which there is no officially released file, there is an easy way to set the right DISTNAME and MASTER_SITES automatically.

As of 2023-02-21 GitHub have announced that source downloads will be stable for a year. Please switch to release assets and if not available ask upstream to generate ones.

These variables are available:

Table 5. `USE_GITHUB` Description
Variable	Description	Default
`GH_ACCOUNT`	Account name of the GitHub user hosting the project	`${PORTNAME}`
`GH_PROJECT`	Name of the project on GitHub	`${PORTNAME}`
`GH_TAGNAME`	Name of the tag to download (2.0.1, hash, …) Using the name of a branch here is incorrect. It is also possible to use the hash of a commit id to do a snapshot.	`${DISTVERSIONPREFIX}${DISTVERSION}${DISTVERSIONSUFFIX}`
`GH_SUBDIR`	When the software needs an additional distribution file to be extracted within `${WRKSRC}`, this variable can be used. See the examples in Fetching Multiple Files from GitHub for more information.	(none)
`GH_TUPLE`	`GH_TUPLE` allows putting `GH_ACCOUNT`, `GH_PROJECT`, `GH_TAGNAME`, and `GH_SUBDIR` into a single variable. The format is account`:`project`:`tagname`:`group`/`subdir. The `/`subdir part is optional. It is helpful when there is more than one GitHub project from which to fetch.

Do not use GH_TUPLE for the default distribution file, as it has no default.

Example 14. Simple Use of USE_GITHUB

While trying to make a port for version 1.2.7 of pkg from the FreeBSD user on github, at https://github.com/freebsd/pkg/, The Makefile would end up looking like this (slightly stripped for the example):

PORTNAME=	pkg
DISTVERSION=	1.2.7

USE_GITHUB=	yes
GH_ACCOUNT=	freebsd

It will automatically have MASTER_SITES set to GH and WRKSRC to ${WRKDIR}/pkg-1.2.7.

Example 15. More Complete Use of USE_GITHUB

While trying to make a port for the bleeding edge version of pkg from the FreeBSD user on github, at https://github.com/freebsd/pkg/, the Makefile ends up looking like this (slightly stripped for the example):

PORTNAME=	pkg-devel
DISTVERSION=	1.3.0.a.20140411

USE_GITHUB=	yes
GH_ACCOUNT=	freebsd
GH_PROJECT=	pkg
GH_TAGNAME=	6dbb17b

It will automatically have MASTER_SITES set to GH and WRKSRC to ${WRKDIR}/pkg-6dbb17b.

20140411 is the date of the commit referenced in GH_TAGNAME, not the date the Makefile is edited, or the date the commit is made.

Example 16. Use of USE_GITHUB with DISTVERSIONPREFIX

From time to time, GH_TAGNAME is a slight variation from DISTVERSION. For example, if the version is 1.0.2, the tag is v1.0.2. In those cases, it is possible to use DISTVERSIONPREFIX or DISTVERSIONSUFFIX:

PORTNAME=	foo
DISTVERSIONPREFIX=	v
DISTVERSION=	1.0.2

USE_GITHUB=	yes

It will automatically set GH_TAGNAME to v1.0.2, while WRKSRC will be kept to ${WRKDIR}/foo-1.0.2.

Example 17. Using USE_GITHUB When Upstream Does Not Use Versions

If there never was a version upstream, do not invent one like 0.1 or 1.0. Create the port with a DISTVERSION of gYYYYMMDD, where g is for Git, and YYYYMMDD represents the date the commit referenced in GH_TAGNAME.

PORTNAME=	bar
DISTVERSION=	g20140411

USE_GITHUB=	yes
GH_TAGNAME=	c472d66b

This creates a versioning scheme that increases over time, and that is still before version 0 (see Using pkg-version\(8] to Compare Versions) for details on pkg-version(8)):

% pkg version -t g20140411 0
<

Which means using PORTEPOCH will not be needed in case upstream decides to cut versions in the future.

Example 18. Using USE_GITHUB to Access a Commit Between Two Versions

If the current version of the software uses a Git tag, and the port needs to be updated to a newer, intermediate version, without a tag, use git-describe(1) to find out the version to use:

% git describe --tags f0038b1
v0.7.3-14-gf0038b1

v0.7.3-14-gf0038b1 can be split into three parts:

v0.7.3: This is the last Git tag that appears in the commit history before the requested commit.
-14: This means that the requested commit, f0038b1, is the 14th commit after the v0.7.3 tag.
-gf0038b1: The -g means "Git", and the f0038b1 is the commit hash that this reference points to.

PORTNAME=	bar
DISTVERSIONPREFIX=  v
DISTVERSION=	0.7.3-14
DISTVERSIONSUFFIX=  -gf0038b1

USE_GITHUB=	yes

This creates a versioning scheme that increases over time (well, over commits), and does not conflict with the creation of a 0.7.4 version. (See Using pkg-version\(8] to Compare Versions) for details on pkg-version(8)):

% pkg version -t 0.7.3 0.7.3.14
<
% pkg version -t 0.7.3.14 0.7.4
<

If the requested commit is the same as a tag, a shorter description is shown by default. The longer version is equivalent:

% git describe --tags c66c71d
v0.7.3

% git describe --tags --long c66c71d
v0.7.3-0-gc66c71d

5.4.3.1. Fetching Multiple Files from GitHub

The USE_GITHUB framework also supports fetching multiple distribution files from different places in GitHub. It works in a way very similar to Multiple Distribution or Patches Files from Multiple Locations.

Multiple values are added to GH_ACCOUNT, GH_PROJECT, and GH_TAGNAME. Each different value is assigned a group. The main value can either have no group, or the :DEFAULT group. A value can be omitted if it is the same as the default as listed in USE_GITHUB Description.

GH_TUPLE can also be used when there are a lot of distribution files. It helps keep the account, project, tagname, and group information at the same place.

For each group, a ${WRKSRC_group} helper variable is created, containing the directory into which the file has been extracted. The ${WRKSRC_group} variables can be used to move directories around during post-extract, or add to CONFIGURE_ARGS, or whatever is needed so that the software builds correctly.

The :group part must be used for only one distribution file. It is used as a unique key and using it more than once will overwrite the previous values.

As this is only syntactic sugar above DISTFILES and MASTER_SITES, the group names must adhere to the restrictions on group names outlined in Multiple Distribution or Patches Files from Multiple Locations

When fetching multiple files from GitHub, sometimes the default distribution file is not fetched from GitHub. To disable fetching the default distribution, set:

USE_GITHUB=	nodefault

When using USE_GITHUB=nodefault, the Makefile must set DISTFILES in its top block. The definition should be:

DISTFILES=    ${DISTNAME}${EXTRACT_SUFX}

Example 19. Use of USE_GITHUB with Multiple Distribution Files

From time to time, there is a need to fetch more than one distribution file. For example, when the upstream git repository uses submodules. This can be done easily using groups in the GH_* variables:

PORTNAME=	foo
DISTVERSION=	1.0.2

USE_GITHUB=	yes
GH_ACCOUNT=	bar:icons,contrib
GH_PROJECT=	foo-icons:icons foo-contrib:contrib
GH_TAGNAME=	1.0:icons fa579bc:contrib
GH_SUBDIR=	ext/icons:icons

CONFIGURE_ARGS=	--with-contrib=${WRKSRC_contrib}

This will fetch three distribution files from github. The default one comes from foo/foo and is version 1.0.2. The second one, with the icons group, comes from bar/foo-icons and is in version 1.0. The third one comes from bar/foo-contrib and uses the Git commit fa579bc. The distribution files are named foo-foo-1.0.2_GH0.tar.gz, bar-foo-icons-1.0_GH0.tar.gz, and bar-foo-contrib-fa579bc_GH0.tar.gz.

All the distribution files are extracted in ${WRKDIR} in their respective subdirectories. The default file is still extracted in ${WRKSRC}, in this case, ${WRKDIR}/foo-1.0.2. Each additional distribution file is extracted in ${WRKSRC_group}. Here, for the icons group, it is called ${WRKSRC_icons} and it contains ${WRKDIR}/foo-icons-1.0. The file with the contrib group is called ${WRKSRC_contrib} and contains ${WRKDIR}/foo-contrib-fa579bc.

The software’s build system expects to find the icons in a ext/icons subdirectory in its sources, so GH_SUBDIR is used. GH_SUBDIR makes sure that ext exists, but that ext/icons does not already exist. Then it does this:

post-extract:
      @${MV} ${WRKSRC_icons} ${WRKSRC}/ext/icons

Example 20. Use of USE_GITHUB with Multiple Distribution Files Using GH_TUPLE

This is functionally equivalent to Use of USE_GITHUB with Multiple Distribution Files, but using GH_TUPLE:

PORTNAME=	foo
DISTVERSION=	1.0.2

USE_GITHUB=	yes
GH_TUPLE=	bar:foo-icons:1.0:icons/ext/icons \
		bar:foo-contrib:fa579bc:contrib

CONFIGURE_ARGS=	--with-contrib=${WRKSRC_contrib}

Grouping was used in the previous example with bar:icons,contrib. Some redundant information is present with GH_TUPLE because grouping is not possible.

Example 21. How to Use USE_GITHUB with Git Submodules?

Ports with GitHub as an upstream repository sometimes use submodules. See git-submodule(1) for more information.

The problem with submodules is that each is a separate repository. As such, they each must be fetched separately.

Using finance/moneymanagerex as an example, its GitHub repository is https://github.com/moneymanagerex/moneymanagerex/. It has a .gitmodules file at the root. This file describes all the submodules used in this repository, and lists additional repositories needed. This file will tell what additional repositories are needed:

[submodule "lib/wxsqlite3"]
	path = lib/wxsqlite3
	url = https://github.com/utelle/wxsqlite3.git
[submodule "3rd/mongoose"]
	path = 3rd/mongoose
	url = https://github.com/cesanta/mongoose.git
[submodule "3rd/LuaGlue"]
	path = 3rd/LuaGlue
	url = https://github.com/moneymanagerex/LuaGlue.git
[submodule "3rd/cgitemplate"]
	path = 3rd/cgitemplate
	url = https://github.com/moneymanagerex/html-template.git
[...]

The only information missing from that file is the commit hash or tag to use as a version. This information is found after cloning the repository:

% git clone --recurse-submodules https://github.com/moneymanagerex/moneymanagerex.git
Cloning into 'moneymanagerex'...

 fb66eb230d8aed21dec273b38c7c054dcb7d6b51 lib/wxsqlite3 (v3.4.0)
[...]

It can also be found on GitHub. Each subdirectory that is a submodule is shown as directory @ hash, for example, mongoose @ 2140e59.

While getting the information from GitHub seems more straightforward, the information found using git submodule status will provide more meaningful information. For example, here, lib/wxsqlite3's commit hash fb66eb2 correspond to v3.4.0. Both can be used interchangeably, but when a tag is available, use it.

Now that all the required information has been gathered, the Makefile can be written (only GitHub-related lines are shown):

PORTNAME=	moneymanagerex
DISTVERSIONPREFIX=	v
DISTVERSION=	1.3.0

USE_GITHUB=	yes
GH_TUPLE=	utelle:wxsqlite3:v3.4.0:wxsqlite3/lib/wxsqlite3 \
		moneymanagerex:LuaGlue:c51d11a:lua_glue/3rd/LuaGlue \
		moneymanagerex:html-template:cd434ee:html_template/3rd/cgitemplate \
		cesanta:mongoose:2140e59:mongoose/3rd/mongoose \
		[...]

5.4.4. `USE_GITLAB`

Similar to GitHub, if the distribution file comes from gitlab.com or is hosting the GitLab software, these variables are available for use and might need to be set.

Table 6. `USE_GITLAB` Description
Variable	Description	Default
`GL_SITE`	Site name hosting the GitLab project	https://gitlab.com/
`GL_ACCOUNT`	Account name of the GitLab user hosting the project	`${PORTNAME}`
`GL_PROJECT`	Name of the project on GitLab	`${PORTNAME}`
`GL_COMMIT`	The commit hash to download. Must be the full 160 bit, 40 character hex sha1 hash. This is a required variable for GitLab.	`(none)`
`GL_SUBDIR`	When the software needs an additional distribution file to be extracted within `${WRKSRC}`, this variable can be used. See the examples in Fetching Multiple Files from GitLab for more information.	(none)
`GL_TUPLE`	`GL_TUPLE` allows putting `GL_SITE`, `GL_ACCOUNT`, `GL_PROJECT`, `GL_COMMIT`, and `GL_SUBDIR` into a single variable. The format is site`:`account`:`project`:`commit`:`group`/`subdir. The site`:` and `/`subdir part is optional. It is helpful when there are more than one GitLab project from which to fetch.

Example 22. Simple Use of USE_GITLAB

While trying to make a port for version 1.14 of libsignon-glib from the accounts-sso user on gitlab.com, at https://gitlab.com/accounts-sso/libsignon-glib/, The Makefile would end up looking like this for fetching the distribution files:

PORTNAME=	libsignon-glib
DISTVERSION=	1.14

USE_GITLAB=	yes
GL_ACCOUNT=	accounts-sso
GL_COMMIT=	e90302e342bfd27bc8c9132ab9d0ea3d8723fd03

It will automatically have MASTER_SITES set to gitlab.com and WRKSRC to ${WRKDIR}/libsignon-glib-e90302e342bfd27bc8c9132ab9d0ea3d8723fd03-e90302e342bfd27bc8c9132ab9d0ea3d8723fd03.

Example 23. More Complete Use of USE_GITLAB

A more complete use of the above if port had no versioning and foobar from the foo user on project bar on a self hosted GitLab site https://gitlab.example.com/, the Makefile ends up looking like this for fetching distribution files:

PORTNAME=	foobar
DISTVERSION=	g20170906

USE_GITLAB=	yes
GL_SITE=	https://gitlab.example.com
GL_ACCOUNT=	foo
GL_PROJECT=	bar
GL_COMMIT=	9c1669ce60c3f4f5eb43df874d7314483fb3f8a6

It will have MASTER_SITES set to "https://gitlab.example.com" and WRKSRC to ${WRKDIR}/bar-9c1669ce60c3f4f5eb43df874d7314483fb3f8a6-9c1669ce60c3f4f5eb43df874d7314483fb3f8a6.

20170906 is the date of the commit referenced in GL_COMMIT, not the date the Makefile is edited, or the date the commit to the FreeBSD ports tree is made.

GL_SITE's protocol, port and webroot can all be modified in the same variable.

5.4.4.1. Fetching Multiple Files from GitLab

The USE_GITLAB framework also supports fetching multiple distribution files from different places from GitLab and GitLab hosted sites. It works in a way very similar to Multiple Distribution or Patches Files from Multiple Locations and Fetching Multiple Files from GitLab.

Multiple values are added to GL_SITE, GL_ACCOUNT, GL_PROJECT and GL_COMMIT. Each different value is assigned a group. USE_GITLAB Description.

GL_TUPLE can also be used when there are a lot of distribution files. It helps keep the site, account, project, commit, and group information at the same place.

The :group part must be used for only one distribution file. It is used as a unique key and using it more than once will overwrite the previous values.

When fetching multiple files using GitLab, sometimes the default distribution file is not fetched from a GitLab site. To disable fetching the default distribution, set:

USE_GITLAB=	nodefault

When using USE_GITLAB=nodefault, the Makefile must set DISTFILES in its top block. The definition should be:

DISTFILES=    ${DISTNAME}${EXTRACT_SUFX}

Example 24. Use of USE_GITLAB with Multiple Distribution Files

PORTNAME=	foo
DISTVERSION=	1.0.2

USE_GITLAB=	yes
GL_SITE=	https://gitlab.example.com:9434/gitlab:icons
GL_ACCOUNT=	bar:icons,contrib
GL_PROJECT=	foo-icons:icons foo-contrib:contrib
GL_COMMIT=	c189207a55da45305c884fe2b50e086fcad4724b ae7368cab1ca7ca754b38d49da064df87968ffe4:icons 9e4dd76ad9b38f33fdb417a4c01935958d5acd2a:contrib
GL_SUBDIR=	ext/icons:icons

CONFIGURE_ARGS= --with-contrib=${WRKSRC_contrib}

This will fetch two distribution files from gitlab.com and one from gitlab.example.com hosting GitLab. The default one comes from https://gitlab.com/foo/foo and commit is c189207a55da45305c884fe2b50e086fcad4724b. The second one, with the icons group, comes from https://gitlab.example.com:9434/gitlab/bar/foo-icons and commit is ae7368cab1ca7ca754b38d49da064df87968ffe4. The third one comes from https://gitlab.com/bar/foo-contrib and is commit 9e4dd76ad9b38f33fdb417a4c01935958d5acd2a. The distribution files are named foo-foo-c189207a55da45305c884fe2b50e086fcad4724b_GL0.tar.gz, bar-foo-icons-ae7368cab1ca7ca754b38d49da064df87968ffe4_GL0.tar.gz, and bar-foo-contrib-9e4dd76ad9b38f33fdb417a4c01935958d5acd2a_GL0.tar.gz.

All the distribution files are extracted in ${WRKDIR} in their respective subdirectories. The default file is still extracted in ${WRKSRC}, in this case, ${WRKDIR}/foo-c189207a55da45305c884fe2b50e086fcad4724b-c189207a55da45305c884fe2b50e086fcad4724b. Each additional distribution file is extracted in ${WRKSRC_group}. Here, for the icons group, it is called ${WRKSRC_icons} and it contains ${WRKDIR}/foo-icons-ae7368cab1ca7ca754b38d49da064df87968ffe4-ae7368cab1ca7ca754b38d49da064df87968ffe4. The file with the contrib group is called ${WRKSRC_contrib} and contains ${WRKDIR}/foo-contrib-9e4dd76ad9b38f33fdb417a4c01935958d5acd2a-9e4dd76ad9b38f33fdb417a4c01935958d5acd2a.

The software’s build system expects to find the icons in a ext/icons subdirectory in its sources, so GL_SUBDIR is used. GL_SUBDIR makes sure that ext exists, but that ext/icons does not already exist. Then it does this:

post-extract:
        @${MV} ${WRKSRC_icons} ${WRKSRC}/ext/icons

Example 25. Use of USE_GITLAB with Multiple Distribution Files Using GL_TUPLE

This is functionally equivalent to Use of USE_GITLAB with Multiple Distribution Files, but using GL_TUPLE:

PORTNAME=	foo
DISTVERSION=	1.0.2

USE_GITLAB=	yes
GL_COMMIT=	c189207a55da45305c884fe2b50e086fcad4724b
GL_TUPLE=	https://gitlab.example.com:9434/gitlab:bar:foo-icons:ae7368cab1ca7ca754b38d49da064df87968ffe4:icons/ext/icons \
		bar:foo-contrib:9e4dd76ad9b38f33fdb417a4c01935958d5acd2a:contrib

CONFIGURE_ARGS= --with-contrib=${WRKSRC_contrib}

Grouping was used in the previous example with bar:icons,contrib. Some redundant information is present with GL_TUPLE because grouping is not possible.

5.4.5. `EXTRACT_SUFX`

If there is one distribution file, and it uses an odd suffix to indicate the compression mechanism, set EXTRACT_SUFX.

For example, if the distribution file was named foo.tar.gzip instead of the more normal foo.tar.gz, write:

DISTNAME=	foo
EXTRACT_SUFX=	.tar.gzip

The USES=tar[:xxx], USES=lha or USES=zip automatically set EXTRACT_SUFX to the most common archives extensions as necessary, see Using USES Macros for more details. If neither of these are set then EXTRACT_SUFX defaults to .tar.gz.

As EXTRACT_SUFX is only used in DISTFILES, only set one of them..

5.4.6. `DISTFILES`

Sometimes the names of the files to be downloaded have no resemblance to the name of the port. For example, it might be called source.tar.gz or similar. In other cases the application’s source code might be in several different archives, all of which must be downloaded.

If this is the case, set DISTFILES to be a space separated list of all the files that must be downloaded.

DISTFILES=	source1.tar.gz source2.tar.gz

If not explicitly set, DISTFILES defaults to ${DISTNAME}${EXTRACT_SUFX}.

5.4.7. `EXTRACT_ONLY`

If only some of the DISTFILES must be extracted-for example, one of them is the source code, while another is an uncompressed document-list the filenames that must be extracted in EXTRACT_ONLY.

DISTFILES=	source.tar.gz manual.html
EXTRACT_ONLY=	source.tar.gz

When none of the DISTFILES need to be uncompressed, set EXTRACT_ONLY to the empty string.

EXTRACT_ONLY=

5.4.8. `PATCHFILES`

If the port requires some additional patches that are available by FTP or HTTP, set PATCHFILES to the names of the files and PATCH_SITES to the URL of the directory that contains them (the format is the same as MASTER_SITES).

If the patch is not relative to the top of the source tree (that is, WRKSRC) because it contains some extra pathnames, set PATCH_DIST_STRIP accordingly. For instance, if all the pathnames in the patch have an extra foozolix-1.0/ in front of the filenames, then set PATCH_DIST_STRIP=-p1.

Do not worry if the patches are compressed; they will be decompressed automatically if the filenames end with .Z, .gz, .bz2 or .xz.

If the patch is distributed with some other files, such as documentation, in a compressed tarball, using PATCHFILES is not possible. If that is the case, add the name and the location of the patch tarball to DISTFILES and MASTER_SITES. Then, use EXTRA_PATCHES to point to those files and bsd.port.mk will automatically apply them. In particular, do not copy patch files into ${PATCHDIR}. That directory may not be writable.

If there are multiple patches and they need mixed values for the strip parameter, it can be added alongside the patch name in PATCHFILES, e.g:

PATCHFILES=	patch1 patch2:-p1

This does not conflict with the master site grouping feature, adding a group also works:

PATCHFILES=	patch2:-p1:source2

The tarball will have been extracted alongside the regular source by then, so there is no need to explicitly extract it if it is a regular compressed tarball. Take extra care not to overwrite something that already exists in that directory if extracting it manually. Also, do not forget to add a command to remove the copied patch in the pre-clean target.

5.4.9. Multiple Distribution or Patches Files from Multiple Locations

(Consider this to be a somewhat "advanced topic"; those new to this document may wish to skip this section at first).

This section has information on the fetching mechanism known as both MASTER_SITES:n and MASTER_SITES_NN. We will refer to this mechanism as MASTER_SITES:n.

A little background first. OpenBSD has a neat feature inside DISTFILES and PATCHFILES which allows files and patches to be postfixed with :n identifiers. Here, n can be any word containing [0-9a-zA-Z_] and denote a group designation. For example:

DISTFILES=	alpha:0 beta:1

In OpenBSD, distribution file alpha will be associated with variable MASTER_SITES0 instead of our common MASTER_SITES and beta with MASTER_SITES1.

This is a very interesting feature which can decrease that endless search for the correct download site.

Just picture 2 files in DISTFILES and 20 sites in MASTER_SITES, the sites slow as hell where beta is carried by all sites in MASTER_SITES, and alpha can only be found in the 20th site. It would be such a waste to check all of them if the maintainer knew this beforehand, would it not? Not a good start for that lovely weekend!

Now that you have the idea, just imagine more DISTFILES and more MASTER_SITES. Surely our "distfiles survey meister" would appreciate the relief to network strain that this would bring.

In the next sections, information will follow on the FreeBSD implementation of this idea. We improved a bit on OpenBSD’s concept.

The group names cannot have dashes in them (-), in fact, they cannot have any characters out of the [a-zA-Z0-9_] range. This is because, while make(1) is ok with variable names containing dashes, sh(1) is not.

5.4.9.1. Simplified Information

This section explains how to quickly prepare fine grained fetching of multiple distribution files and patches from different sites and subdirectories. We describe here a case of simplified MASTER_SITES:n usage. This will be sufficient for most scenarios. More detailed information are available in Detailed Information.

Some applications consist of multiple distribution files that must be downloaded from a number of different sites. For example, Ghostscript consists of the core of the program, and then a large number of driver files that are used depending on the user’s printer. Some of these driver files are supplied with the core, but many others must be downloaded from a variety of different sites.

To support this, each entry in DISTFILES may be followed by a colon and a "group name". Each site listed in MASTER_SITES is then followed by a colon, and the group that indicates which distribution files are downloaded from this site.

For example, consider an application with the source split in two parts, source1.tar.gz and source2.tar.gz, which must be downloaded from two different sites. The port’s Makefile would include lines like Simplified Use of MASTER_SITES:n with One File Per Site.

Example 26. Simplified Use of MASTER_SITES:n with One File Per Site

MASTER_SITES=	ftp://ftp1.example.com/:source1 \
		http://www.example.com/:source2
DISTFILES=	source1.tar.gz:source1 \
		source2.tar.gz:source2

Multiple distribution files can have the same group. Continuing the previous example, suppose that there was a third distfile, source3.tar.gz, that is downloaded from ftp.example2.com. The Makefile would then be written like Simplified Use of MASTER_SITES:n with More Than One File Per Site.

Example 27. Simplified Use of MASTER_SITES:n with More Than One File Per Site

MASTER_SITES=	ftp://ftp.example.com/:source1 \
		http://www.example.com/:source2
DISTFILES=	source1.tar.gz:source1 \
		source2.tar.gz:source2 \
		source3.tar.gz:source2

5.4.9.2. Detailed Information

Okay, so the previous example did not reflect the new port’s needs? In this section we will explain in detail how the fine grained fetching mechanism MASTER_SITES:n works and how it can be used.

Elements can be postfixed with :n where n is `, that is, _n_ could conceptually be any alphanumeric string but we will limit it to `[a-zA-Z_][0-9a-zA-Z_] for now.
Moreover, string matching is case sensitive; that is, n is different from N.
However, these words cannot be used for postfixing purposes since they yield special meaning: default, all and ALL (they are used internally in item ii). Furthermore, DEFAULT is a special purpose word (check item 3).
Elements postfixed with :n belong to the group n, :m belong to group m and so forth.
Elements without a postfix are groupless, they all belong to the special group DEFAULT. Any elements postfixed with DEFAULT, is just being redundant unless an element belongs to both DEFAULT and other groups at the same time (check item 5).
These examples are equivalent but the first one is preferred:
```
MASTER_SITES=	alpha
```
```
MASTER_SITES=	alpha:DEFAULT
```
Groups are not exclusive, an element may belong to several different groups at the same time and a group can either have either several different elements or none at all.
When an element belongs to several groups at the same time, use the comma operator (,).
Instead of repeating it several times, each time with a different postfix, we can list several groups at once in a single postfix. For instance, :m,n,o marks an element that belongs to group m, n and o.
All these examples are equivalent but the last one is preferred:
```
MASTER_SITES=	alpha alpha:SOME_SITE
```
```
MASTER_SITES=	alpha:DEFAULT alpha:SOME_SITE
```
```
MASTER_SITES=	alpha:SOME_SITE,DEFAULT
```
```
MASTER_SITES=	alpha:DEFAULT,SOME_SITE
```
All sites within a given group are sorted according to MASTER_SORT_AWK. All groups within MASTER_SITES and PATCH_SITES are sorted as well.
Group semantics can be used in any of the variables MASTER_SITES, PATCH_SITES, MASTER_SITE_SUBDIR, PATCH_SITE_SUBDIR, DISTFILES, and PATCHFILES according to this syntax:
1. All MASTER_SITES, PATCH_SITES, MASTER_SITE_SUBDIR and PATCH_SITE_SUBDIR elements must be terminated with the forward slash / character. If any elements belong to any groups, the group postfix :n must come right after the terminator /. The MASTER_SITES:n mechanism relies on the existence of the terminator / to avoid confusing elements where a :n is a valid part of the element with occurrences where :n denotes group n. For compatibility purposes, since the / terminator was not required before in both MASTER_SITE_SUBDIR and PATCH_SITE_SUBDIR elements, if the postfix immediate preceding character is not a / then :n will be considered a valid part of the element instead of a group postfix even if an element is postfixed with :n. See both Detailed Use of MASTER_SITES:n in MASTER_SITE_SUBDIR and Detailed Use of MASTER_SITES:n with Comma Operator.
  Example 28. Detailed Use of MASTER_SITES:n in MASTER_SITE_SUBDIR
  MASTER_SITE_SUBDIR= old:n new/:NEW
  Directories within group DEFAULT → old:n
  Directories within group NEW → new
  Example 29. Detailed Use of MASTER_SITES:n with Comma Operator, Multiple Files, Multiple Sites and Multiple Subdirectories
  MASTER_SITES= http://site1/%SUBDIR%/ http://site2/:DEFAULT \ http://site3/:group3 http://site4/:group4 \ http://site5/:group5 http://site6/:group6 \ http://site7/:DEFAULT,group6 \ http://site8/%SUBDIR%/:group6,group7 \ http://site9/:group8 DISTFILES= file1 file2:DEFAULT file3:group3 \ file4:group4,group5,group6 file5:grouping \ file6:group7 MASTER_SITE_SUBDIR= directory-trial:1 directory-n/:groupn \ directory-one/:group6,DEFAULT \ directory
  The previous example results in this fine grained fetching. Sites are listed in the exact order they will be used.
  file1 will be fetched from
  MASTER_SITE_OVERRIDE
  http://site1/directory-trial:1/
  http://site1/directory-one/
  http://site1/directory/
  http://site2/
  http://site7/
  MASTER_SITE_BACKUP
  file2 will be fetched exactly as file1 since they both belong to the same group
  MASTER_SITE_OVERRIDE
  http://site1/directory-trial:1/
  http://site1/directory-one/
  http://site1/directory/
  http://site2/
  http://site7/
  MASTER_SITE_BACKUP
  file3 will be fetched from
  MASTER_SITE_OVERRIDE
  http://site3/
  MASTER_SITE_BACKUP
  file4 will be fetched from
  MASTER_SITE_OVERRIDE
  http://site4/
  http://site5/
  http://site6/
  http://site7/
  http://site8/directory-one/
  MASTER_SITE_BACKUP
  file5 will be fetched from
  MASTER_SITE_OVERRIDE
  MASTER_SITE_BACKUP
  file6 will be fetched from
  MASTER_SITE_OVERRIDE
  http://site8/
  MASTER_SITE_BACKUP
How do I group one of the special macros from bsd.sites.mk, for example, SourceForge (SF)?
This has been simplified as much as possible. See Detailed Use of MASTER_SITES:n with SourceForge (SF).
Example 30. Detailed Use of MASTER_SITES:n with SourceForge (SF)
MASTER_SITES= http://site1/ SF/something/1.0:sourceforge,TEST DISTFILES= something.tar.gz:sourceforge
something.tar.gz will be fetched from all sites within SourceForge.
How do I use this with PATCH*?
All examples were done with MASTER* but they work exactly the same for PATCH* ones as can be seen in Simplified Use of MASTER_SITES:n with PATCH_SITES.
Example 31. Simplified Use of MASTER_SITES:n with PATCH_SITES
PATCH_SITES= http://site1/ http://site2/:test PATCHFILES= patch1:test

5.4.9.3. What Does Change for Ports? What Does Not?

All current ports remain the same. The MASTER_SITES:n feature code is only activated if there are elements postfixed with :n like elements according to the aforementioned syntax rules, especially as shown in item 7.
The port targets remain the same: checksum, makesum, patch, configure, build, etc. With the obvious exceptions of do-fetch, fetch-list, master-sites and patch-sites.
- do-fetch: deploys the new grouping postfixed DISTFILES and PATCHFILES with their matching group elements within both MASTER_SITES and PATCH_SITES which use matching group elements within both MASTER_SITE_SUBDIR and PATCH_SITE_SUBDIR. Check Detailed Use of MASTER_SITES:n with Comma Operator.
- fetch-list: works like old fetch-list with the exception that it groups just like do-fetch.
- master-sites and patch-sites: (incompatible with older versions) only return the elements of group DEFAULT; in fact, they execute targets master-sites-default and patch-sites-default respectively.
  Furthermore, using target either master-sites-all or patch-sites-all is preferred to directly checking either MASTER_SITES or PATCH_SITES. Also, directly checking is not guaranteed to work in any future versions. Check item B for more information on these new port targets.
New port targets
1. There are master-sites-n and patch-sites-n targets which will list the elements of the respective group n within MASTER_SITES and PATCH_SITES respectively. For instance, both master-sites-DEFAULT and patch-sites-DEFAULT will return the elements of group DEFAULT, master-sites-test and patch-sites-test of group test, and thereon.
2. There are new targets master-sites-all and patch-sites-all which do the work of the old master-sites and patch-sites ones. They return the elements of all groups as if they all belonged to the same group with the caveat that it lists as many MASTER_SITE_BACKUP and MASTER_SITE_OVERRIDE as there are groups defined within either DISTFILES or PATCHFILES; respectively for master-sites-all and patch-sites-all.

5.4.10. `DIST_SUBDIR`

Do not let the port clutter /usr/ports/distfiles. If the port requires a lot of files to be fetched, or contains a file that has a name that might conflict with other ports (for example, Makefile), set DIST_SUBDIR to the name of the port (${PORTNAME} or ${PKGNAMEPREFIX}${PORTNAME} are fine). This will change DISTDIR from the default /usr/ports/distfiles to /usr/ports/distfiles/${DIST_SUBDIR}, and in effect puts everything that is required for the port into that subdirectory.

It will also look at the subdirectory with the same name on the backup master site at http://distcache.FreeBSD.org (Setting DISTDIR explicitly in Makefile will not accomplish this, so please use DIST_SUBDIR.)

This does not affect MASTER_SITES defined in the Makefile.

5.5. `MAINTAINER`

Set your mail-address here. Please. :-)

Only a single address without the comment part is allowed as a MAINTAINER value. The format used is user@hostname.domain. Please do not include any descriptive text such as a real name in this entry. That merely confuses the Ports infrastructure and most tools using it.

The maintainer is responsible for keeping the port up to date and making sure that it works correctly. For a detailed description of the responsibilities of a port maintainer, refer to The challenge for port maintainers.

A maintainer volunteers to keep a port in good working order. Maintainers have the primary responsibility for their ports, but not exclusive ownership. Ports exist for the benefit of the community and, in reality, belong to the community. What this means is that people other than the maintainer can make changes to a port. Large changes to the Ports Collection might require changes to many ports. The FreeBSD Ports Management Team or members of other teams might modify ports to fix dependency issues or other problems, like a version bump for a shared library update.

Some types of fixes have "blanket approval" from the Ports Management Team <portmgr@FreeBSD.org>, allowing any committer to fix those categories of problems on any port. These fixes do not need approval from the maintainer.

Blanket approval for most ports applies to fixes like infrastructure changes, or trivial and tested build and runtime fixes. The current list is available in Ports section of the Committer’s Guide.

Other changes to the port will be sent to the maintainer for review and approval before being committed. If the maintainer does not respond to an update request after two weeks (excluding major public holidays), then that is considered a maintainer timeout, and the update can be made without explicit maintainer approval. If the maintainer does not respond within three months, or if there have been three consecutive timeouts, then that maintainer is considered absent without leave, and all of their ports can be assigned back to the pool. Exceptions to this are anything maintained by the Ports Management Team <portmgr@FreeBSD.org>, or the Security Officer Team <security-officer@FreeBSD.org>. No unauthorized commits may ever be made to ports maintained by those groups.

We reserve the right to modify the maintainer’s submission to better match existing policies and style of the Ports Collection without explicit blessing from the submitter or the maintainer. Also, large infrastructural changes can result in a port being modified without the maintainer’s consent. These kinds of changes will never affect the port’s functionality.

The Ports Management Team <portmgr@FreeBSD.org> reserves the right to revoke or override anyone’s maintainership for any reason, and the Security Officer Team <security-officer@FreeBSD.org> reserves the right to revoke or override maintainership for security reasons.

5.6. `COMMENT`

The comment is a one-line description of a port shown by pkg info. Please follow these rules when composing it:

The COMMENT string should be 70 characters or less.
Do not include the package name or version number of software.
The comment must begin with a capital and end without a period.
Do not start with an indefinite article (that is, A or An).
Capitalize names such as Apache, JavaScript, or Perl.
Use a serial comma for lists of words: "green, red, and blue."
Check for spelling errors.

Here is an example:

COMMENT=	Cat chasing a mouse all over the screen

The COMMENT variable immediately follows the MAINTAINER variable in the Makefile.

5.7. Project website

Each port should point to a website that provides more information about the software.

Whenever possible, this should be the official project website maintained by the developers of the software.

WWW=		https://ffmpeg.org/

But it can also be a directory or resource in the source code repository:

WWW=		https://sourceforge.net/projects/mpd/

The WWW variable immediately follows the COMMENT variable in the Makefile.

If the same content can be accessed via HTTP and HTTPS, the URL starting with https:// shall be used. If the URI is the root of the website or directory, it must be terminated with a slash.

This information used to be placed into the last line of the pkg-descr file. It has been moved into the Makefile for easier maintenance and processing. Having a WWW: line at the end of the pkg-descr file is deprecated.

5.8. Licenses

Each port must document the license under which it is available. If it is not an OSI approved license it must also document any restrictions on redistribution.

5.8.1. `LICENSE`

A short name for the license or licenses if more than one license apply.

If it is one of the licenses listed in Predefined License List, only LICENSE_FILE and LICENSE_DISTFILES variables can be set.

If this is a license that has not been defined in the ports framework (see Predefined License List), the LICENSE_PERMS and LICENSE_NAME must be set, along with either LICENSE_FILE or LICENSE_TEXT. LICENSE_DISTFILES and LICENSE_GROUPS can also be set, but are not required.

The predefined licenses are shown in Predefined License List. The current list is always available in Mk/bsd.licenses.db.mk.

Example 32. Simplest Usage, Predefined Licenses

When the README of some software says "This software is under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version." but does not provide the license file, use this:

LICENSE=	LGPL21+

When the software provides the license file, use this:

LICENSE=	LGPL21+
LICENSE_FILE=	${WRKSRC}/COPYING

For the predefined licenses, the default permissions are dist-mirror dist-sell pkg-mirror pkg-sell auto-accept.

Permissions. use none if empty.

License Permissions List

dist-mirror: Redistribution of the distribution files is permitted. The distribution files will be added to the FreeBSD MASTER_SITE_BACKUP CDN.

no-dist-mirror: Redistribution of the distribution files is prohibited. This is equivalent to setting RESTRICTED. The distribution files will not be added to the FreeBSD MASTER_SITE_BACKUP CDN.

dist-sell: Selling of distribution files is permitted. The distribution files will be present on the installer images.

no-dist-sell: Selling of distribution files is prohibited. This is equivalent to setting NO_CDROM.

pkg-mirror: Free redistribution of package is permitted. The package will be distributed on the FreeBSD package CDN https://pkg.freebsd.org/.

no-pkg-mirror: Free redistribution of package is prohibited. Equivalent to setting NO_PACKAGE. The package will not be distributed from the FreeBSD package CDN https://pkg.freebsd.org/.

pkg-sell: Selling of package is permitted. The package will be present on the installer images.

no-pkg-sell: Selling of package is prohibited. This is equivalent to setting NO_CDROM. The package will not be present on the installer images.

auto-accept: License is accepted by default. Prompts to accept a license are not displayed unless the user has defined LICENSES_ASK. Use this unless the license states the user must accept the terms of the license.

no-auto-accept: License is not accepted by default. The user will always be asked to confirm the acceptance of this license. This must be used if the license states that the user must accept its terms.

When both permission and no-permission is present the no-permission will cancel permission.

When permission is not present, it is considered to be a no-permission.

Some missing permissions will prevent a port (and all ports depending on it) from being usable by package users:

A port without the auto-accept permission will never be be built and all the ports depending on it will be ignored.

A port without the pkg-mirror permission will be removed, as well as all the ports depending on it, after the build and they will ever end up being distributed.

Example 33. Nonstandard License

Read the terms of the license and translate those using the available permissions.

LICENSE=        UNKNOWN
LICENSE_NAME=   unknown
LICENSE_TEXT=   This program is NOT in public domain.\
                It can be freely distributed for non-commercial purposes only.
LICENSE_PERMS=  dist-mirror no-dist-sell pkg-mirror no-pkg-sell auto-accept

Example 34. Standard and Nonstandard Licenses

Read the terms of the license and express those using the available permissions. In case of doubt, please ask for guidance on the FreeBSD ports mailing list.

LICENSE=        WARSOW GPLv2
LICENSE_COMB=   multi
LICENSE_NAME_WARSOW=    Warsow Content License
LICENSE_FILE_WARSOW=    ${WRKSRC}/docs/license.txt
LICENSE_PERMS_WARSOW=   dist-mirror pkg-mirror auto-accept

When the permissions of the GPLv2 and the UNKNOWN licenses are mixed, the port ends up with dist-mirror dist-sell pkg-mirror pkg-sell auto-accept dist-mirror no-dist-sell pkg-mirror no-pkg-sell auto-accept. The no-permissions cancel the permissions. The resulting list of permissions are dist-mirror pkg-mirror auto-accept. The distribution files and the packages will not be available on the installer images.

5.8.3. `LICENSE_GROUPS` and `LICENSE_GROUPS_NAME`

Groups the license belongs.

Predefined License Groups List

FSF: Free Software Foundation Approved, see the FSF Licensing & Compliance Team.

GPL: GPL Compatible

OSI: OSI Approved, see the Open Source Initiative Open Source Licenses page.

COPYFREE: Comply with Copyfree Standard Definition, see the Copyfree Licenses page.

FONTS: Font licenses

5.8.4. `LICENSE_NAME` and `LICENSE_NAME_NAME`

Full name of the license.

Example 35. LICENSE_NAME

LICENSE=        UNRAR
LICENSE_NAME=   UnRAR License
LICENSE_FILE=   ${WRKSRC}/license.txt
LICENSE_PERMS=  dist-mirror dist-sell pkg-mirror pkg-sell auto-accept

5.8.5. `LICENSE_FILE` and `LICENSE_FILE_NAME`

Full path to the file containing the license text, usually ${WRKSRC}/some/file. If the file is not in the distfile, and its content is too long to be put in LICENSE_TEXT, put it in a new file in ${FILESDIR}.

Example 36. LICENSE_FILE

LICENSE=	GPLv3+
LICENSE_FILE=	${WRKSRC}/COPYING

5.8.6. `LICENSE_TEXT` and `LICENSE_TEXT_NAME`

Text to use as a license. Useful when the license is not in the distribution files and its text is short.

Example 37. LICENSE_TEXT

LICENSE=        UNKNOWN
LICENSE_NAME=   unknown
LICENSE_TEXT=   This program is NOT in public domain.\
                It can be freely distributed for non-commercial purposes only,\
                and THERE IS NO WARRANTY FOR THIS PROGRAM.
LICENSE_PERMS=  dist-mirror no-dist-sell pkg-mirror no-pkg-sell auto-accept

5.8.7. `LICENSE_DISTFILES` and `LICENSE_DISTFILES_NAME`

The distribution files to which the licenses apply. Defaults to all the distribution files.

Example 38. LICENSE_DISTFILES

Used when the distribution files do not all have the same license. For example, one has a code license, and another has some artwork that cannot be redistributed:

MASTER_SITES=   SF/some-game
DISTFILES=      ${DISTNAME}${EXTRACT_SUFX} artwork.zip

LICENSE=        BSD3CLAUSE ARTWORK
LICENSE_COMB=   dual
LICENSE_NAME_ARTWORK=      The game artwork license
LICENSE_TEXT_ARTWORK=      The README says that the files cannot be redistributed
LICENSE_PERMS_ARTWORK=     pkg-mirror pkg-sell auto-accept
LICENSE_DISTFILES_BSD3CLAUSE=   ${DISTNAME}${EXTRACT_SUFX}
LICENSE_DISTFILES_ARTWORK= artwork.zip

5.8.8. `LICENSE_COMB`

Set to multi if all licenses apply. Set to dual if any license applies. Defaults to single.

Example 39. Dual Licenses

When a port says "This software may be distributed under the GNU General Public License or the Artistic License", it means that either license can be used. Use this:

LICENSE=	ART10 GPLv1
LICENSE_COMB=   dual

If license files are provided, use this:

LICENSE=	ART10 GPLv1
LICENSE_COMB=   dual
LICENSE_FILE_ART10=     ${WRKSRC}/Artistic
LICENSE_FILE_GPLv1=     ${WRKSRC}/Copying

Example 40. Multiple Licenses

When part of a port has one license, and another part has a different license, use multi:

LICENSE=	GPLv2 LGPL21+
LICENSE_COMB=	multi

5.9. `PORTSCOUT`

Portscout is an automated distfile check utility for the FreeBSD Ports Collection, described in detail in Portscout: the FreeBSD Ports Distfile Scanner.

PORTSCOUT defines special conditions within which the Portscout distfile scanner is restricted.

Situations where PORTSCOUT is set include:

When distfiles have to be ignored for specific versions. For example, to exclude version 8.2 and version 8.3 from distfile version checks because they are known to be broken, add:
```
PORTSCOUT=	skipv:8.2,8.3
```
When distfile version checks have to be disabled completely. For example, if a port is not going to be updated ever again, add:
```
PORTSCOUT=	ignore:1
```
When specific versions or specific major and minor revisions of a distfile must be checked. For example, if only version 0.6.4 must be monitored because newer versions have compatibility issues with FreeBSD, add:
```
PORTSCOUT=	limit:^0\.6\.4
```
When URLs listing the available versions differ from the download URLs. For example, to limit distfile version checks to the download page for the databases/pgtune port, add:
```
PORTSCOUT=	site:http://www.renpy.org/dl/release/
```

5.10. Dependencies

Many ports depend on other ports. This is a very convenient feature of most Unix-like operating systems, including FreeBSD. Multiple ports can share a common dependency, rather than bundling that dependency with every port or package that needs it. There are seven variables that can be used to ensure that all the required bits will be on the user’s machine. There are also some pre-supported dependency variables for common cases, plus a few more to control the behavior of dependencies.

When software has extra dependencies that provide extra features, the base dependencies listed in *_DEPENDS should include the extra dependencies that would benefit most users. The base dependencies should never be a "minimal" dependency set. The goal is not to include every dependency possible. Only include those that will benefit most people.

5.10.1. `LIB_DEPENDS`

This variable specifies the shared libraries this port depends on. It is a list of lib:dir tuples where lib is the name of the shared library, dir is the directory in which to find it in case it is not available. For example,

LIB_DEPENDS=   libjpeg.so:graphics/jpeg

will check for a shared jpeg library with any version, and descend into the graphics/jpeg subdirectory of the ports tree to build and install it if it is not found.

The dependency is checked twice, once from within the build target and then from within the install target. Also, the name of the dependency is put into the package so that pkg install (see pkg-install(8)) will automatically install it if it is not on the user’s system.

5.10.2. `RUN_DEPENDS`

This variable specifies executables or files this port depends on during run-time. It is a list of path:dir[:target] tuples where path is the name of the executable or file, dir is the directory in which to find it in case it is not available, and target is the target to call in that directory. If path starts with a slash (/), it is treated as a file and its existence is tested with test -e; otherwise, it is assumed to be an executable, and which -s is used to determine if the program exists in the search path.

For example,

RUN_DEPENDS=	${LOCALBASE}/news/bin/innd:news/inn \
		xmlcatmgr:textproc/xmlcatmgr

will check if the file or directory /usr/local/news/bin/innd exists, and build and install it from the news/inn subdirectory of the ports tree if it is not found. It will also see if an executable called xmlcatmgr is in the search path, and descend into textproc/xmlcatmgr to build and install it if it is not found.

In this case, innd is actually an executable; if an executable is in a place that is not expected to be in the search path, use the full pathname.

The official search PATH used on the ports build cluster is

/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin

The dependency is checked from within the install target. Also, the name of the dependency is put into the package so that pkg install (see pkg-install(8)) will automatically install it if it is not on the user’s system. The target part can be omitted if it is the same as DEPENDS_TARGET.

A quite common situation is when RUN_DEPENDS is literally the same as BUILD_DEPENDS, especially if ported software is written in a scripted language or if it requires the same build and run-time environment. In this case, it is both tempting and intuitive to directly assign one to the other:

RUN_DEPENDS=	${BUILD_DEPENDS}

However, such assignment can pollute run-time dependencies with entries not defined in the port’s original BUILD_DEPENDS. This happens because of make(1)'s lazy evaluation of variable assignment. Consider a Makefile with USE_*, which are processed by ports/Mk/bsd.*.mk to augment initial build dependencies. For example, USES= gmake adds devel/gmake to BUILD_DEPENDS. To prevent such additional dependencies from polluting RUN_DEPENDS, create another variable with the current content of BUILD_DEPENDS and assign it to both BUILD_DEPENDS and RUN_DEPENDS:

MY_DEPENDS=	some:devel/some \
		other:lang/other
BUILD_DEPENDS=	${MY_DEPENDS}
RUN_DEPENDS=	${MY_DEPENDS}

Do not use := to assign BUILD_DEPENDS to RUN_DEPENDS or vice-versa. All variables are expanded immediately, which is exactly the wrong thing to do and almost always a failure.

5.10.3. `BUILD_DEPENDS`

This variable specifies executables or files this port requires to build. Like RUN_DEPENDS, it is a list of path:dir[:target] tuples. For example,

BUILD_DEPENDS=	unzip:archivers/unzip

will check for an executable called unzip, and descend into the archivers/unzip subdirectory of the ports tree to build and install it if it is not found.

"build" here means everything from extraction to compilation. The dependency is checked from within the extract target. The target part can be omitted if it is the same as DEPENDS_TARGET

5.10.4. `FETCH_DEPENDS`

This variable specifies executables or files this port requires to fetch. Like the previous two, it is a list of path:dir[:target] tuples. For example,

FETCH_DEPENDS=	ncftp2:net/ncftp2

will check for an executable called ncftp2, and descend into the net/ncftp2 subdirectory of the ports tree to build and install it if it is not found.

The dependency is checked from within the fetch target. The target part can be omitted if it is the same as DEPENDS_TARGET.

5.10.5. `EXTRACT_DEPENDS`

This variable specifies executables or files this port requires for extraction. Like the previous, it is a list of path:dir[:target] tuples. For example,

EXTRACT_DEPENDS=	unzip:archivers/unzip

will check for an executable called unzip, and descend into the archivers/unzip subdirectory of the ports tree to build and install it if it is not found.

The dependency is checked from within the extract target. The target part can be omitted if it is the same as DEPENDS_TARGET.

Use this variable only if the extraction does not already work (the default assumes tar) and cannot be made to work using USES=tar, USES=lha or USES=zip described in Using USES Macros.

5.10.6. `PATCH_DEPENDS`

This variable specifies executables or files this port requires to patch. Like the previous, it is a list of path:dir[:target] tuples. For example,

PATCH_DEPENDS=	${NONEXISTENT}:java/jfc:extract

will descend into the java/jfc subdirectory of the ports tree to extract it.

The dependency is checked from within the patch target. The target part can be omitted if it is the same as DEPENDS_TARGET.

5.10.7. `USES`

Parameters can be added to define different features and dependencies used by the port. They are specified by adding this line to the Makefile:

USES= feature[:arguments]

For the complete list of values, please see Using USES Macros.

USES cannot be assigned after inclusion of bsd.port.pre.mk.

5.10.8. `USE_*`

Several variables exist to define common dependencies shared by many ports. Their use is optional, but helps to reduce the verbosity of the port Makefiles. Each of them is styled as USE_*. These variables may be used only in the port Makefiles and ports/Mk/bsd.*.mk. They are not meant for user-settable options - use PORT_OPTIONS for that purpose.

It is always incorrect to set any USE_* in /etc/make.conf. For instance, setting

USE_GCC=X.Y

(where X.Y is version number) would add a dependency on gccXY for every port, including lang/gccXY itself!

Variable Means

USE_GCC

The port requires GCC (gcc or g++) to build. Some ports need a specific, old GCC version, some require modern, recent versions. It is typically set to yes (means always use stable, modern GCC from ports per GCC_DEFAULT in Mk/bsd.default-versions.mk). This is also the default value. The exact version can also be specified, with a value such as 10. GCC from the base system is used when it satisfies the requested version, otherwise an appropriate compiler is built from ports, and CC and CXX are adjusted accordingly. The :build argument following the version specifier adds only a build time dependency to the port.

For example:

USE_GCC=yes		# port requires a current version of GCC
USE_GCC=11:build	# port requires GCC 11 at build time only

USE_GCC=any is deprecated and should not be used in new ports

Variables related to gmake and configure are described in Building Mechanisms, while autoconf, automake and libtool are described in Using GNU Autotools. Perl related variables are described in Using Perl. X11 variables are listed in Using X11. Using Gnome deals with GNOME and Using KDE with KDE related variables. Using Java documents Java variables, while Web Applications contains information on Apache, PHP and PEAR modules. Python is discussed in Using Python, while Ruby in Using Ruby. Using SDL provides variables used for SDL applications and finally, Using Xfce contains information on Xfce.

5.10.9. Minimal Version of a Dependency

A minimal version of a dependency can be specified in any *_DEPENDS except LIB_DEPENDS using this syntax:

p5-Spiffy>=0.26:devel/p5-Spiffy

The first field contains a dependent package name, which must match the entry in the package database, a comparison sign, and a package version. The dependency is satisfied if p5-Spiffy-0.26 or newer is installed on the machine.

5.10.10. Notes on Dependencies

As mentioned above, the default target to call when a dependency is required is DEPENDS_TARGET. It defaults to install. This is a user variable; it is never defined in a port’s Makefile. If the port needs a special way to handle a dependency, use the :target part of *_DEPENDS instead of redefining DEPENDS_TARGET.

When running make clean, the port dependencies are automatically cleaned too. If this is not desirable, define NOCLEANDEPENDS in the environment. This may be particularly desirable if the port has something that takes a long time to rebuild in its dependency list, such as KDE, GNOME or Mozilla.

To depend on another port unconditionally, use the variable ${NONEXISTENT} as the first field of BUILD_DEPENDS or RUN_DEPENDS. Use this only when the source of the other port is needed. Compilation time can be saved by specifying the target too. For instance

BUILD_DEPENDS=	${NONEXISTENT}:graphics/jpeg:extract

will always descend to the jpeg port and extract it.

5.10.11. Circular Dependencies Are Fatal

Do not introduce any circular dependencies into the ports tree!

The ports building technology does not tolerate circular dependencies. If one is introduced, someone, somewhere in the world, will have their FreeBSD installation broken almost immediately, with many others quickly to follow. These can really be hard to detect. If in doubt, before making that change, make sure to run: cd /usr/ports; make index. That process can be quite slow on older machines, but it may be able to save a large number of people, including yourself, a lot of grief in the process.

5.10.12. Problems Caused by Automatic Dependencies

Dependencies must be declared either explicitly or by using the OPTIONS framework. Using other methods like automatic detection complicates indexing, which causes problems for port and package management.

Example 41. Wrong Declaration of an Optional Dependency

.include <bsd.port.pre.mk>

.if exists(${LOCALBASE}/bin/foo)
LIB_DEPENDS=	libbar.so:foo/bar
.endif

The problem with trying to automatically add dependencies is that files and settings outside an individual port can change at any time. For example: an index is built, then a batch of ports are installed. But one of the ports installs the tested file. The index is now incorrect, because an installed port unexpectedly has a new dependency. The index may still be wrong even after rebuilding if other ports also determine their need for dependencies based on the existence of other files.

Example 42. Correct Declaration of an Optional Dependency

OPTIONS_DEFINE=	BAR
BAR_DESC=	Calling cellphones via bar

BAR_LIB_DEPENDS=	libbar.so:foo/bar

Testing option variables is the correct method. It will not cause inconsistencies in the index of a batch of ports, provided the options were defined prior to the index build. Simple scripts can then be used to automate the building, installation, and updating of these ports and their packages.

5.11. Slave Ports and `MASTERDIR`

If the port needs to build slightly different versions of packages by having a variable (for instance, resolution, or paper size) take different values, create one subdirectory per package to make it easier for users to see what to do, but try to share as many files as possible between ports. Typically, by using variables cleverly, only a very short Makefile is needed in all but one of the directories. In the sole Makefile, use MASTERDIR to specify the directory where the rest of the files are. Also, use a variable as part of PKGNAMESUFFIX so the packages will have different names.

This will be best demonstrated by an example. This is part of print/pkfonts300/Makefile;

PORTNAME=	pkfonts${RESOLUTION}
PORTVERSION=	1.0
DISTFILES=	pk${RESOLUTION}.tar.gz

PLIST=		${PKGDIR}/pkg-plist.${RESOLUTION}

.if !defined(RESOLUTION)
RESOLUTION=	300
.else
.if ${RESOLUTION} != 118 && ${RESOLUTION} != 240 && \
	${RESOLUTION} != 300 && ${RESOLUTION} != 360 && \
	${RESOLUTION} != 400 && ${RESOLUTION} != 600
.BEGIN:
	@${ECHO_MSG} "Error: invalid value for RESOLUTION: \"${RESOLUTION}\""
	@${ECHO_MSG} "Possible values are: 118, 240, 300, 360, 400 and 600."
	@${FALSE}
.endif
.endif

print/pkfonts300 also has all the regular patches, package files, etc. Running make there, it will take the default value for the resolution (300) and build the port normally.

As for other resolutions, this is the entire print/pkfonts360/Makefile:

RESOLUTION=	360
MASTERDIR=	${.CURDIR}/../pkfonts300

.include	"${MASTERDIR}/Makefile"

(print/pkfonts118/Makefile, print/pkfonts600/Makefile, and all the other are similar). MASTERDIR definition tells bsd.port.mk that the regular set of subdirectories like FILESDIR and SCRIPTDIR are to be found under pkfonts300. The RESOLUTION=360 line will override the RESOLUTION=300 line in pkfonts300/Makefile and the port will be built with resolution set to 360.

5.12. Man Pages

If the port anchors its man tree somewhere other than PREFIX, use MANDIRS to specify those directories. Note that the files corresponding to manual pages must be placed in pkg-plist along with the rest of the files. The purpose of MANDIRS is to enable automatic compression of manual pages, therefore the file names are suffixed with .gz.

5.13. Info Files

If the package needs to install GNU info files, list them in INFO (without the trailing .info), one entry per document. These files are assumed to be installed to PREFIX/INFO_PATH. Change INFO_PATH if the package uses a different location. However, this is not recommended. These entries contain just the path relative to PREFIX/INFO_PATH. For example, lang/gcc34 installs info files to PREFIX/INFO_PATH/gcc34, and INFO will be something like this:

INFO=	gcc34/cpp gcc34/cppinternals gcc34/g77 ...

Appropriate installation/de-installation code will be automatically added to the temporary pkg-plist before package registration.

5.14. Makefile Options

Many applications can be built with optional or differing configurations. Examples include choice of natural (human) language, GUI versus command-line, or type of database to support. Users may need a different configuration than the default, so the ports system provides hooks the port author can use to control which variant will be built. Supporting these options properly will make users happy, and effectively provide two or more ports for the price of one.

5.14.1. `OPTIONS`

5.14.1.1. Background

OPTIONS_* give the user installing the port a dialog showing the available options, and then saves those options to ${PORT_DBDIR}/${OPTIONS_NAME}/options. The next time the port is built, the options are reused. PORT_DBDIR defaults to /var/db/ports. OPTIONS_NAME is to the port origin with an underscore as the space separator, for example, for dns/bind99 it will be dns_bind99.

When the user runs make config (or runs make build for the first time), the framework checks for ${PORT_DBDIR}/${OPTIONS_NAME}/options. If that file does not exist, the values of OPTIONS_* are used, and a dialog box is displayed where the options can be enabled or disabled. Then options is saved and the configured variables are used when building the port.

If a new version of the port adds new OPTIONS, the dialog will be presented to the user with the saved values of old OPTIONS prefilled.

make showconfig shows the saved configuration. Use make rmconfig to remove the saved configuration.

5.14.1.2. Syntax

OPTIONS_DEFINE contains a list of OPTIONS to be used. These are independent of each other and are not grouped:

OPTIONS_DEFINE=	OPT1 OPT2

Once defined, OPTIONS are described (optional, but strongly recommended):

OPT1_DESC=	Describe OPT1
OPT2_DESC=	Describe OPT2
OPT3_DESC=	Describe OPT3
OPT4_DESC=	Describe OPT4
OPT5_DESC=	Describe OPT5
OPT6_DESC=	Describe OPT6

ports/Mk/bsd.options.desc.mk has descriptions for many common OPTIONS. While often useful, override them if the description is insufficient for the port.

When describing options, view it from the perspective of the user: "What functionality does it change?" and "Why would I want to enable this?" Do not just repeat the name. For example, describing the NLS option as "include NLS support" does not help the user, who can already see the option name but may not know what it means. Describing it as "Native Language Support via gettext utilities" is much more helpful.

Option names are always in all uppercase. They cannot use mixed case or lowercase.

OPTIONS can be grouped as radio choices, where only one choice from each group is allowed:

OPTIONS_SINGLE=		SG1
OPTIONS_SINGLE_SG1=	OPT3 OPT4

There must be one of each OPTIONS_SINGLE group selected at all times for the options to be valid. One option of each group must be added to OPTIONS_DEFAULT.

OPTIONS can be grouped as radio choices, where none or only one choice from each group is allowed:

OPTIONS_RADIO=		RG1
OPTIONS_RADIO_RG1=	OPT7 OPT8

OPTIONS can also be grouped as "multiple-choice" lists, where at least one option must be enabled:

OPTIONS_MULTI=		MG1
OPTIONS_MULTI_MG1=	OPT5 OPT6

OPTIONS can also be grouped as "multiple-choice" lists, where none or any option can be enabled:

OPTIONS_GROUP=		GG1
OPTIONS_GROUP_GG1=	OPT9 OPT10

OPTIONS are unset by default, unless they are listed in OPTIONS_DEFAULT:

OPTIONS_DEFAULT=	OPT1 OPT3 OPT6

OPTIONS definitions must appear before the inclusion of bsd.port.options.mk. PORT_OPTIONS values can only be tested after the inclusion of bsd.port.options.mk. Inclusion of bsd.port.pre.mk can be used instead, too, and is still widely used in ports written before the introduction of bsd.port.options.mk. But be aware that some variables will not work as expected after the inclusion of bsd.port.pre.mk, typically some USE_* flags.

Example 43. Simple Use of OPTIONS

OPTIONS_DEFINE=	FOO BAR
OPTIONS_DEFAULT=FOO

FOO_DESC=	Option foo support
BAR_DESC=	Feature bar support

# Will add --with-foo / --without-foo
FOO_CONFIGURE_WITH=	foo
BAR_RUN_DEPENDS=	bar:bar/bar

.include <bsd.port.mk>

Example 44. Check for Unset Port OPTIONS

.if ! ${PORT_OPTIONS:MEXAMPLES}
CONFIGURE_ARGS+=--without-examples
.endif

The form shown above is discouraged. The preferred method is using a configure knob to really enable and disable the feature to match the option:

# Will add --with-examples / --without-examples
EXAMPLES_CONFIGURE_WITH=	examples

Example 45. Practical Use of OPTIONS

OPTIONS_DEFINE=		EXAMPLES
OPTIONS_DEFAULT=	PGSQL LDAP SSL

OPTIONS_SINGLE=		BACKEND
OPTIONS_SINGLE_BACKEND=	MYSQL PGSQL BDB

OPTIONS_MULTI=		AUTH
OPTIONS_MULTI_AUTH=	LDAP PAM SSL

EXAMPLES_DESC=		Install extra examples
MYSQL_DESC=		Use MySQL as backend
PGSQL_DESC=		Use PostgreSQL as backend
BDB_DESC=		Use Berkeley DB as backend
LDAP_DESC=		Build with LDAP authentication support
PAM_DESC=		Build with PAM support
SSL_DESC=		Build with OpenSSL support

# Will add USE_PGSQL=yes
PGSQL_USE=	pgsql=yes
# Will add --enable-postgres / --disable-postgres
PGSQL_CONFIGURE_ENABLE=	postgres

ICU_LIB_DEPENDS=	libicuuc.so:devel/icu

# Will add --with-examples / --without-examples
EXAMPLES_CONFIGURE_WITH=	examples

# Check other OPTIONS

.include <bsd.port.mk>

5.14.1.3. Default Options

These options are always on by default.

DOCS - build and install documentation.
NLS - Native Language Support.
EXAMPLES - build and install examples.
IPV6 - IPv6 protocol support.

There is no need to add these to OPTIONS_DEFAULT. To have them active, and show up in the options selection dialog, however, they must be added to OPTIONS_DEFINE.

5.14.2. Feature Auto-Activation

When using a GNU configure script, keep an eye on which optional features are activated by auto-detection. Explicitly disable optional features that are not needed by adding --without-xxx or --disable-xxx in CONFIGURE_ARGS.

Example 46. Wrong Handling of an Option

.if ${PORT_OPTIONS:MFOO}
LIB_DEPENDS+=		libfoo.so:devel/foo
CONFIGURE_ARGS+=	--enable-foo
.endif

In the example above, imagine a library libfoo is installed on the system. The user does not want this application to use libfoo, so he toggled the option off in the make config dialog. But the application’s configure script detects the library present in the system and includes its support in the resulting executable. Now when the user decides to remove libfoo from the system, the ports system does not protest (no dependency on libfoo was recorded) but the application breaks.

Example 47. Correct Handling of an Option

FOO_LIB_DEPENDS=		libfoo.so:devel/foo
# Will add --enable-foo / --disable-foo
FOO_CONFIGURE_ENABLE=	foo

Under some circumstances, the shorthand conditional syntax can cause problems with complex constructs. The errors are usually Malformed conditional, an alternative syntax can be used.

.if !empty(VARIABLE:MVALUE)

as an alternative to

.if ${VARIABLE:MVALUE}

5.14.3. Options Helpers

There are some macros to help simplify conditional values which differ based on the options set. For easier access, a comprehensive list is provided:

PLIST_SUB, SUB_LIST: For automatic %%OPT%% and %%NOOPT%% generation, see OPTIONS_SUB.
For more complex usage, see Generic Variables Replacement.
CONFIGURE_ARGS: For --enable-x and --disable-x, see OPT_CONFIGURE_ENABLE.
For --with-x and --without-x, see OPT_CONFIGURE_WITH.
For all other cases, see OPT_CONFIGURE_ON and OPT_CONFIGURE_OFF.
CMAKE_ARGS: For arguments that are booleans (on, off, true, false, 0, 1) see OPT_CMAKE_BOOL and OPT_CMAKE_BOOL_OFF.
For all other cases, see OPT_CMAKE_ON and OPT_CMAKE_OFF.
MESON_ARGS: For arguments that take true or false, see OPT_MESON_TRUE and OPT_MESON_FALSE.
For arguments that take yes or no, use OPT_MESON_YES and OPT_MESON_NO.
For arguments that take enabled or disabled, see OPT_MESON_ENABLED and OPT_MESON_DISABLED.
For all other cases, use OPT_MESON_ON and OPT_MESON_OFF.
QMAKE_ARGS: See OPT_QMAKE_ON and OPT_QMAKE_OFF.
USE_*: See OPT_USE and OPT_USE_OFF.
*_DEPENDS: See Dependencies.
* (Any variable): The most used variables have direct helpers, see Generic Variables Replacement.
For any variable without a specific helper, see OPT_VARS and OPT_VARS_OFF.
Options dependencies: When an option need another option to work, see OPT_IMPLIES.
Options conflicts: When an option cannot work if another is also enabled, see OPT_PREVENTS and OPT_PREVENTS_MSG.
Build targets: When an option need some extra processing, see Additional Build Targets.

5.14.3.1. `OPTIONS_SUB`

If OPTIONS_SUB is set to yes then each of the options added to OPTIONS_DEFINE will be added to PLIST_SUB and SUB_LIST, for example:

OPTIONS_DEFINE=	OPT1
OPTIONS_SUB=	yes

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
PLIST_SUB+=	OPT1="" NO_OPT1="@comment "
SUB_LIST+=	OPT1="" NO_OPT1="@comment "
.else
PLIST_SUB+=	OPT1="@comment " NO_OPT1=""
SUB_LIST+=	OPT1="@comment " NO_OPT1=""
.endif

The value of OPTIONS_SUB is ignored. Setting it to any value will add PLIST_SUB and SUB_LIST entries for all options.

5.14.3.2. `OPT_USE` and `OPT_USE_OFF`

When option OPT is selected, for each key=value pair in OPT_USE, value is appended to the corresponding USE_KEY. If value has spaces in it, replace them with commas and they will be changed back to spaces during processing. OPT_USE_OFF works the same way, but when OPT is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_USES=	xorg
OPT1_USE=	mysql=yes xorg=x11,xextproto,xext,xrandr
OPT1_USE_OFF=	openssl=yes

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
USE_MYSQL=	yes
USES+=		xorg
USE_XORG=	x11 xextproto xext xrandr
.else
USE_OPENSSL=	yes
.endif

5.14.3.3. `CONFIGURE_ARGS` Helpers

5.14.3.3.1. `OPT_CONFIGURE_ENABLE`

When option OPT is selected, for each entry in OPT_CONFIGURE_ENABLE then --enable-entry is appended to CONFIGURE_ARGS. When option OPT is not selected, --disable-entry is appended to CONFIGURE_ARGS. An optional argument can be specified with an = symbol. This argument is only appended to the --enable-entry configure option. For example:

OPTIONS_DEFINE=	OPT1 OPT2
OPT1_CONFIGURE_ENABLE=	test1 test2
OPT2_CONFIGURE_ENABLE=	test2=exhaustive

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
CONFIGURE_ARGS+=	--enable-test1 --enable-test2
.else
CONFIGURE_ARGS+=	--disable-test1 --disable-test2
.endif

.if ${PORT_OPTIONS:MOPT2}
CONFIGURE_ARGS+=	--enable-test2=exhaustive
.else
CONFIGURE_ARGS+=	--disable-test2
.endif

5.14.3.3.2. `OPT_CONFIGURE_WITH`

When option OPT is selected, for each entry in OPT_CONFIGURE_WITH then --with-_entry is appended to CONFIGURE_ARGS. When option OPT is not selected, --without-entry is appended to CONFIGURE_ARGS. An optional argument can be specified with an = symbol. This argument is only appended to the --with-entry configure option. For example:

OPTIONS_DEFINE=	OPT1 OPT2
OPT1_CONFIGURE_WITH=	test1
OPT2_CONFIGURE_WITH=	test2=exhaustive

is equivalent to:

OPTIONS_DEFINE=	OPT1 OPT2

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
CONFIGURE_ARGS+=	--with-test1
.else
CONFIGURE_ARGS+=	--without-test1
.endif

.if ${PORT_OPTIONS:MOPT2}
CONFIGURE_ARGS+=	--with-test2=exhaustive
.else
CONFIGURE_ARGS+=	--without-test2
.endif

5.14.3.3.3. `OPT_CONFIGURE_ON` and `OPT_CONFIGURE_OFF`

When option OPT is selected, the value of OPT_CONFIGURE_ON, if defined, is appended to CONFIGURE_ARGS. OPT_CONFIGURE_OFF works the same way, but when OPT is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_CONFIGURE_ON=	--add-test
OPT1_CONFIGURE_OFF=	--no-test

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
CONFIGURE_ARGS+=	--add-test
.else
CONFIGURE_ARGS+=	--no-test
.endif

Most of the time, the helpers in OPT_CONFIGURE_ENABLE and OPT_CONFIGURE_WITH provide a shorter and more comprehensive functionality.

5.14.3.4. `CMAKE_ARGS` Helpers

5.14.3.4.1. `OPT_CMAKE_ON` and `OPT_CMAKE_OFF`

When option OPT is selected, the value of OPT_CMAKE_ON, if defined, is appended to CMAKE_ARGS. OPT_CMAKE_OFF works the same way, but when OPT is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_CMAKE_ON=	-DTEST:BOOL=true -DDEBUG:BOOL=true
OPT1_CMAKE_OFF=	-DOPTIMIZE:BOOL=true

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
CMAKE_ARGS+=	-DTEST:BOOL=true -DDEBUG:BOOL=true
.else
CMAKE_ARGS+=	-DOPTIMIZE:BOOL=true
.endif

See OPT_CMAKE_BOOL and OPT_CMAKE_BOOL_OFF for a shorter helper when the value is boolean.

5.14.3.4.2. `OPT_CMAKE_BOOL` and `OPT_CMAKE_BOOL_OFF`

When option OPT is selected, for each entry in OPT_CMAKE_BOOL then -D_entry_:BOOL=true is appended to CMAKE_ARGS. When option OPT is not selected, -D_entry_:BOOL=false is appended to CONFIGURE_ARGS. OPT_CMAKE_BOOL_OFF is the opposite, -D_entry_:BOOL=false is appended to CMAKE_ARGS when the option is selected, and -D_entry_:BOOL=true when the option is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_CMAKE_BOOL=	TEST DEBUG
OPT1_CMAKE_BOOL_OFF=	OPTIMIZE

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
CMAKE_ARGS+=	-DTEST:BOOL=true -DDEBUG:BOOL=true \
		-DOPTIMIZE:BOOL=false
.else
CMAKE_ARGS+=	-DTEST:BOOL=false -DDEBUG:BOOL=false \
		-DOPTIMIZE:BOOL=true
.endif

5.14.3.5. `MESON_ARGS` Helpers

5.14.3.5.1. `OPT_MESON_ON` and `OPT_MESON_OFF`

When option OPT is selected, the value of OPT_MESON_ON, if defined, is appended to MESON_ARGS. OPT_MESON_OFF works the same way, but when OPT is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_MESON_ON=	-Dopt=1
OPT1_MESON_OFF=	-Dopt=2

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
MESON_ARGS+=	-Dopt=1
.else
MESON_ARGS+=	-Dopt=2
.endif

5.14.3.5.2. `OPT_MESON_TRUE` and `OPT_MESON_FALSE`

When option OPT is selected, for each entry in OPT_MESON_TRUE then -D_entry_=true is appended to MESON_ARGS. When option OPT is not selected, -D_entry_=false is appended to MESON_ARGS. OPT_MESON_FALSE is the opposite, -D_entry_=false is appended to MESON_ARGS when the option is selected, and -D_entry_=true when the option is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_MESON_TRUE=	test debug
OPT1_MESON_FALSE=	optimize

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
MESON_ARGS+=	-Dtest=true -Ddebug=true \
		-Doptimize=false
.else
MESON_ARGS+=	-Dtest=false -Ddebug=false \
		-Doptimize=true
.endif

5.14.3.5.3. `OPT_MESON_YES` and `OPT_MESON_NO`

When option OPT is selected, for each entry in OPT_MESON_YES then -D_entry_=yes is appended to MESON_ARGS. When option OPT is not selected, -D_entry_=no is appended to MESON_ARGS. OPT_MESON_NO is the opposite, -D_entry_=no is appended to MESON_ARGS when the option is selected, and -D_entry_=yes when the option is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_MESON_YES=	test debug
OPT1_MESON_NO=	optimize

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
MESON_ARGS+=	-Dtest=yes -Ddebug=yes \
		-Doptimize=no
.else
MESON_ARGS+=	-Dtest=no -Ddebug=no \
		-Doptimize=yes
.endif

5.14.3.5.4. `OPT_MESON_ENABLED` and `OPT_MESON_DISABLED`

When option OPT is selected, for each entry in OPT_MESON_ENABLED then -D_entry_=enabled is appended to MESON_ARGS. When option OPT is not selected, -D_entry_=disabled is appended to MESON_ARGS. OPT_MESON_DISABLED is the opposite, -D_entry_=disabled is appended to MESON_ARGS when the option is selected, and -D_entry_=enabled when the option is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_MESON_ENABLED=	test
OPT1_MESON_DISABLED=	debug

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
MESON_ARGS+=	-Dtest=enabled -Ddebug=disabled
.else
MESON_ARGS+=	-Dtest=disabled -Ddebug=enabled
.endif

5.14.3.6. `OPT_QMAKE_ON` and `OPT_QMAKE_OFF`

When option OPT is selected, the value of OPT_QMAKE_ON, if defined, is appended to QMAKE_ARGS. OPT_QMAKE_OFF works the same way, but when OPT is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_QMAKE_ON=	-DTEST:BOOL=true
OPT1_QMAKE_OFF=	-DPRODUCTION:BOOL=true

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
QMAKE_ARGS+=	-DTEST:BOOL=true
.else
QMAKE_ARGS+=	-DPRODUCTION:BOOL=true
.endif

5.14.3.7. `OPT_IMPLIES`

Provides a way to add dependencies between options.

When OPT is selected, all the options listed in this variable will be selected too. Using the OPT_CONFIGURE_ENABLE described earlier to illustrate:

OPTIONS_DEFINE=	OPT1 OPT2
OPT1_IMPLIES=	OPT2

OPT1_CONFIGURE_ENABLE=	opt1
OPT2_CONFIGURE_ENABLE=	opt2

Is equivalent to:

OPTIONS_DEFINE=	OPT1 OPT2

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
CONFIGURE_ARGS+=	--enable-opt1
.else
CONFIGURE_ARGS+=	--disable-opt1
.endif

.if ${PORT_OPTIONS:MOPT2} || ${PORT_OPTIONS:MOPT1}
CONFIGURE_ARGS+=	--enable-opt2
.else
CONFIGURE_ARGS+=	--disable-opt2
.endif

Example 48. Simple Use of OPT_IMPLIES

This port has a X11 option, and a GNOME option that needs the X11 option to be selected to build.

OPTIONS_DEFINE=	X11 GNOME
OPTIONS_DEFAULT=	X11

X11_USES=	xorg
X11_USE=	xorg=xi,xextproto
GNOME_USE=	gnome=gtk30
GNOME_IMPLIES=	X11

5.14.3.8. `OPT_PREVENTS` and `OPT_PREVENTS_MSG`

Provides a way to add conflicts between options.

When OPT is selected, all the options listed in OPT_PREVENTS must be un-selected. If OPT_PREVENTS_MSG is set and a conflict is triggered, its content will be shown explaining why they conflict. For example:

OPTIONS_DEFINE=	OPT1 OPT2
OPT1_PREVENTS=	OPT2
OPT1_PREVENTS_MSG=	OPT1 and OPT2 enable conflicting options

Is roughly equivalent to:

OPTIONS_DEFINE=	OPT1 OPT2

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT2} && ${PORT_OPTIONS:MOPT1}
BROKEN=	Option OPT1 conflicts with OPT2 (select only one)
.endif

The only difference is that the first one will write an error after running make config, suggesting changing the selected options.

Example 49. Simple Use of OPT_PREVENTS

This port has X509 and SCTP options. Both options add patches, but the patches conflict with each other, so they cannot be selected at the same time.

OPTIONS_DEFINE=	X509 SCTP

SCTP_PATCHFILES=	${PORTNAME}-6.8p1-sctp-2573.patch.gz:-p1
SCTP_CONFIGURE_WITH=	sctp

X509_PATCH_SITES=	http://www.roumenpetrov.info/openssh/x509/:x509
X509_PATCHFILES=	${PORTNAME}-7.0p1+x509-8.5.diff.gz:-p1:x509
X509_PREVENTS=		SCTP
X509_PREVENTS_MSG=	X509 and SCTP patches conflict

5.14.3.9. `OPT_VARS` and `OPT_VARS_OFF`

Provides a generic way to set and append to variables.

Before using OPT_VARS and OPT_VARS_OFF, see if there is already a more specific helper available in Generic Variables Replacement.

When option OPT is selected, and OPT_VARS defined, key=value and key+=value pairs are evaluated from OPT_VARS. An = cause the existing value of KEY to be overwritten, an += appends to the value. OPT_VARS_OFF works the same way, but when OPT is not selected.

OPTIONS_DEFINE=	OPT1 OPT2 OPT3
OPT1_VARS=	also_build+=bin1
OPT2_VARS=	also_build+=bin2
OPT3_VARS=	bin3_build=yes
OPT3_VARS_OFF=	bin3_build=no

MAKE_ARGS=	ALSO_BUILD="${ALSO_BUILD}" BIN3_BUILD="${BIN3_BUILD}"

is equivalent to:

OPTIONS_DEFINE=	OPT1 OPT2

MAKE_ARGS=	ALSO_BUILD="${ALSO_BUILD}" BIN3_BUILD="${BIN3_BUILD}"

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
ALSO_BUILD+=	bin1
.endif

.if ${PORT_OPTIONS:MOPT2}
ALSO_BUILD+=	bin2
.endif

.if ${PORT_OPTIONS:MOPT2}
BIN3_BUILD=	yes
.else
BIN3_BUILD=	no
.endif

Values containing whitespace must be enclosed in quotes:

OPT_VARS=	foo="bar baz"

This is due to the way make(1) variable expansion deals with whitespace. When OPT_VARS= foo=bar baz is expanded, the variable ends up containing two strings, foo=bar and baz. But the submitter probably intended there to be only one string, foo=bar baz. Quoting the value prevents whitespace from being used as a delimiter.

Also, do not add extra spaces after the var= sign and before the value, it would also be split into two strings. This will not work:

OPT_VARS=	foo=	bar

5.14.3.10. Dependencies, `OPT_DEPTYPE` and `OPT_DEPTYPE_OFF`

For any of these dependency types:

PKG_DEPENDS
EXTRACT_DEPENDS
PATCH_DEPENDS
FETCH_DEPENDS
BUILD_DEPENDS
LIB_DEPENDS
RUN_DEPENDS

When option OPT is selected, the value of OPT_DEPTYPE, if defined, is appended to DEPTYPE. OPT_DEPTYPE_OFF works the same, but when OPT is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_LIB_DEPENDS=	liba.so:devel/a
OPT1_LIB_DEPENDS_OFF=	libb.so:devel/b

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
LIB_DEPENDS+=	liba.so:devel/a
.else
LIB_DEPENDS+=	libb.so:devel/b
.endif

5.14.3.11. Generic Variables Replacement, `OPT_VARIABLE` and `OPT_VARIABLE_OFF`

For any of these variables:

ALL_TARGET
BINARY_ALIAS
BROKEN
CATEGORIES
CFLAGS
CONFIGURE_ENV
CONFLICTS
CONFLICTS_BUILD
CONFLICTS_INSTALL
CPPFLAGS
CXXFLAGS
DESKTOP_ENTRIES
DISTFILES
EXTRACT_ONLY
EXTRA_PATCHES
GH_ACCOUNT
GH_PROJECT
GH_SUBDIR
GH_TAGNAME
GH_TUPLE
GL_ACCOUNT
GL_COMMIT
GL_PROJECT
GL_SITE
GL_SUBDIR
GL_TUPLE
IGNORE
INFO
INSTALL_TARGET
LDFLAGS
LIBS
MAKE_ARGS
MAKE_ENV
MASTER_SITES
PATCHFILES
PATCH_SITES
PLIST_DIRS
PLIST_FILES
PLIST_SUB
PORTDOCS
PORTEXAMPLES
SUB_FILES
SUB_LIST
TEST_TARGET
USES

When option OPT is selected, the value of OPT_ABOVEVARIABLE, if defined, is appended to ABOVEVARIABLE. OPT_ABOVEVARIABLE_OFF works the same way, but when OPT is not selected. For example:

OPTIONS_DEFINE=	OPT1
OPT1_USES=	gmake
OPT1_CFLAGS_OFF=	-DTEST

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MOPT1}
USES+=		gmake
.else
CFLAGS+=	-DTEST
.endif

Some variables are not in this list, in particular PKGNAMEPREFIX and PKGNAMESUFFIX. This is intentional. A port must not change its name when its option set changes.

Some of these variables, at least ALL_TARGET, DISTFILES and INSTALL_TARGET, have their default values set after the options are processed.

With these lines in the Makefile:

ALL_TARGET=	all

DOCS_ALL_TARGET=	doc

If the DOCS option is enabled, ALL_TARGET will have a final value of all doc; if the option is disabled, it would have a value of all.

With only the options helper line in the Makefile:

DOCS_ALL_TARGET=	doc

If the DOCS option is enabled, ALL_TARGET will have a final value of doc; if the option is disabled, it would have a value of all.

5.14.3.12. Additional Build Targets, `target-OPT-on` and `target-OPT-off`

These Makefile targets can accept optional extra build targets:

pre-fetch
do-fetch
post-fetch
pre-extract
do-extract
post-extract
pre-patch
do-patch
post-patch
pre-configure
do-configure
post-configure
pre-build
do-build
post-build
pre-install
do-install
post-install
post-stage
pre-package
do-package
post-package

When option OPT is selected, the target TARGET-OPT-on, if defined, is executed after TARGET. TARGET-OPT-off works the same way, but when OPT is not selected. For example:

OPTIONS_DEFINE=	OPT1

post-patch-OPT1-on:
	@${REINPLACE_CMD} -e '/opt1/s|/usr/bin/|${EXAMPLESDIR}/|' ${WRKSRC}/Makefile

post-patch-OPT1-off:
	@${REINPLACE_CMD} -e '/opt1/s|/usr/bin/|${PREFIX}/bin/|' ${WRKSRC}/Makefile

is equivalent to:

OPTIONS_DEFINE=	OPT1

.include <bsd.port.options.mk>

post-patch:
.if ${PORT_OPTIONS:MOPT1}
	@${REINPLACE_CMD} -e '/opt1/s|/usr/bin/|${EXAMPLESDIR}/|' ${WRKSRC}/Makefile
.else
	@${REINPLACE_CMD} -e '/opt1/s|/usr/bin/|${PREFIX}/bin/|' ${WRKSRC}/Makefile
.endif

5.15. Specifying the Working Directory

Each port is extracted into a working directory, which must be writable. The ports system defaults to having DISTFILES unpack in to a directory called ${DISTNAME}. In other words, if the Makefile has:

PORTNAME=	foo
DISTVERSION=	1.0

then the port’s distribution files contain a top-level directory, foo-1.0, and the rest of the files are located under that directory.

A number of variables can be overridden if that is not the case.

5.15.1. `WRKSRC`

The variable lists the name of the directory that is created when the application’s distfiles are extracted. If our previous example extracted into a directory called foo (and not foo-1.0) write:

WRKSRC=	${WRKDIR}/foo

or possibly

WRKSRC=	${WRKDIR}/${PORTNAME}

5.15.2. `WRKSRC_SUBDIR`

If the source files needed for the port are in a subdirectory of the extracted distribution file, set WRKSRC_SUBDIR to that directory.

WRKSRC_SUBDIR=	src

5.15.3. `NO_WRKSUBDIR`

If the port does not extract in to a subdirectory at all, then set NO_WRKSUBDIR to indicate that.

NO_WRKSUBDIR=	yes

Because WRKDIR is the only directory that is supposed to be writable during the build, and is used to store many files recording the status of the build, the port’s extraction will be forced into a subdirectory.

5.16. Conflict Handling

There are three different variables to register a conflict between packages and ports: CONFLICTS, CONFLICTS_INSTALL and CONFLICTS_BUILD.

The conflict variables automatically set the variable IGNORE, which is more fully documented in Marking a Port Not Installable with BROKEN.

When removing one of several conflicting ports, it is advisable to retain CONFLICTS in those other ports for a few months to cater for users who only update once in a while.

CONFLICTS_INSTALL: If the package cannot coexist with other packages (because of file conflicts, runtime incompatibilities, etc.). CONFLICTS_INSTALL check is done after the build stage and prior to the install stage.

CONFLICTS_BUILD: If the port cannot be built when other specific ports are already installed. Build conflicts are not recorded in the resulting package.

CONFLICTS: If the port cannot be built if a certain port is already installed and the resulting package cannot coexist with the other package. CONFLICTS check is done prior to the build stage and prior to the install stage.

Each space-separated item in the CONFLICTS* variable values is matched against packages except the one being built, using shell globbing rules. This allows listing all flavors of a port in a conflict list instead of having to take pains to exclude the flavor being built from that list. For example, if git-lite is installed, CONFLICTS_INSTALL=git git-lite would allow to perform:

% make -C devel/git FLAVOR=lite all deinstall install

But the following command would report a conflict, since the package base name installed is git-lite, while git would be built, but cannot be installed in addition to git-lite:

% make -C devel/git FLAVOR=default all deinstall install

Without that feature, the Makefile would need one _flavor__CONFLICTS_INSTALL for each flavor, listing every other flavor.

The most common content of one of these variable is the package base of another port. The package base is the package name without the appended version, it can be obtained by running make -V PKGBASE.

Example 50. Basic usage of CONFLICTS*

dns/bind99 cannot be installed if dns/bind910 is present because they install same files. First gather the package base to use:

% make -C dns/bind99 -V PKGBASE
bind99
% make -C dns/bind910 -V PKGBASE
bind910

Then add to the Makefile of dns/bind99:

CONFLICTS_INSTALL=	bind910

And add to the Makefile of dns/bind910:

CONFLICTS_INSTALL=	bind99

Sometimes, only certain versions of another port are incompatible. When this is the case, use the full package name including the version. If necessary, use shell globs like * and ? so that all necessary versions are matched.

Example 51. Using CONFLICTS* With Globs.

From versions from 2.0 and up-to 2.4.1_2, deskutils/gnotime used to install a bundled version of databases/qof.

To reflect this past, the Makefile of databases/qof contains:

CONFLICTS_INSTALL=	gnotime-2.[0-3]* \
			gnotime-2.4.0* gnotime-2.4.1 \
			gnotime-2.4.1_[12]

The first entry match versions 2.0 through 2.3, the second all the revisions of 2.4.0, the third the exact 2.4.1 version, and the last the first and second revisions of the 2.4.1 version.

deskutils/gnotime does not have any conflicts line because its current version does not conflict with anything else.

The variable DISABLE_CONFLICTS may be temporarily set when making targets that are not affected by conflicts. The variable is not to be set in port Makefiles.

% make -DDISABLE_CONFLICTS patch

5.17. Installing Files

The install phase is very important to the end user because it adds files to their system. All the additional commands run in the port Makefile's *-install targets should be echoed to the screen. Do not silence these commands with @ or .SILENT.

5.17.1. `INSTALL_*` Macros

Use the macros provided in bsd.port.mk to ensure correct modes of files in the port’s *-install targets. Set ownership directly in pkg-plist with the corresponding entries, such as @(owner,group,), @owner owner, and @group group. These operators work until overridden, or until the end of pkg-plist, so remember to reset them after they are no longer needed. The default ownership is root:wheel. See Base Keywords for more information.

INSTALL_PROGRAM is a command to install binary executables.
INSTALL_SCRIPT is a command to install executable scripts.
INSTALL_LIB is a command to install shared libraries (but not static libraries).
INSTALL_KLD is a command to install kernel loadable modules. Some architectures do not like having the modules stripped, so use this command instead of INSTALL_PROGRAM.
INSTALL_DATA is a command to install sharable data, including static libraries.
INSTALL_MAN is a command to install manpages and other documentation (it does not compress anything).

These variables are set to the install(1) command with the appropriate flags for each situation.

Do not use INSTALL_LIB to install static libraries, because stripping them renders them useless. Use INSTALL_DATA instead.

5.17.2. Stripping Binaries and Shared Libraries

Installed binaries should be stripped. Do not strip binaries manually unless absolutely required. The INSTALL_PROGRAM macro installs and strips a binary at the same time. The INSTALL_LIB macro does the same thing to shared libraries.

When a file must be stripped, but neither INSTALL_PROGRAM nor INSTALL_LIB macros are desirable, ${STRIP_CMD} strips the program or shared library. This is typically done within the post-install target. For example:

post-install:
	${STRIP_CMD} ${STAGEDIR}${PREFIX}/bin/xdl

When multiple files need to be stripped:

post-install:
.for l in geometry media body track world
	${STRIP_CMD} ${STAGEDIR}${PREFIX}/lib/lib${PORTNAME}-${l}.so.0
.endfor

Use file(1) on a file to determine if it has been stripped. Binaries are reported by file(1) as stripped, or not stripped. Additionally, strip(1) will detect programs that have already been stripped and exit cleanly.

When WITH_DEBUG is defined, elf files must not be stripped.

The variables (STRIP_CMD, INSTALL_PROGRAM, INSTALL_LIB, …) and USES provided by the framework handle this automatically.

Some software, add -s to their LDFLAGS, in this case, either remove -s if WITH_DEBUG is set, or remove it unconditionally and use STRIP_CMD in post-install.

5.17.3. Installing a Whole Tree of Files

Sometimes, a large number of files must be installed while preserving their hierarchical organization. For example, copying over a whole directory tree from WRKSRC to a target directory under PREFIX. Note that PREFIX, EXAMPLESDIR, DATADIR, and other path variables must always be prepended with STAGEDIR to respect staging (see Staging).

Two macros exist for this situation. The advantage of using these macros instead of cp is that they guarantee proper file ownership and permissions on target files. The first macro, COPYTREE_BIN, will set all the installed files to be executable, thus being suitable for installing into PREFIX/bin. The second macro, COPYTREE_SHARE, does not set executable permissions on files, and is therefore suitable for installing files under PREFIX/share target.

post-install:
	${MKDIR} ${STAGEDIR}${EXAMPLESDIR}
	(cd ${WRKSRC}/examples && ${COPYTREE_SHARE} . ${STAGEDIR}${EXAMPLESDIR})

This example will install the contents of the examples directory in the vendor distfile to the proper examples location of the port.

post-install:
	${MKDIR} ${STAGEDIR}${DATADIR}/summer
	(cd ${WRKSRC}/temperatures && ${COPYTREE_SHARE} "June July August" ${STAGEDIR}${DATADIR}/summer)

And this example will install the data of summer months to the summer subdirectory of a DATADIR.

Additional find arguments can be passed via the third argument to COPYTREE_* macros. For example, to install all files from the first example except Makefiles, one can use these commands.

post-install:
	${MKDIR} ${STAGEDIR}${EXAMPLESDIR}
	(cd ${WRKSRC}/examples && \
	${COPYTREE_SHARE} . ${STAGEDIR}${EXAMPLESDIR} "! -name Makefile")

These macros do not add the installed files to pkg-plist. They must be added manually. For optional documentation (PORTDOCS, see Install Additional Documentation) and examples (PORTEXAMPLES), the %%PORTDOCS%% or %%PORTEXAMPLES%% prefixes must be prepended in pkg-plist.

5.17.4. Install Additional Documentation

If the software has some documentation other than the standard man and info pages that is useful for the user, install it under DOCSDIR. This can be done, like the previous item, in the post-install target.

Create a new directory for the port. The directory name is DOCSDIR. This usually equals PORTNAME. However, if the user might want different versions of the port to be installed at the same time, the whole PKGNAME can be used.

Since only the files listed in pkg-plist are installed, it is safe to always install documentation to STAGEDIR (see Staging). Hence .if blocks are only needed when the installed files are large enough to cause significant I/O overhead.

post-install:
	${MKDIR} ${STAGEDIR}${DOCSDIR}
	${INSTALL_DATA} ${WRKSRC}/docs/xvdocs.ps ${STAGEDIR}${DOCSDIR}

On the other hand, if there is a DOCS option in the port, install the documentation in a post-install-DOCS-on target. These targets are described in Additional Build Targets.

Here are some handy variables and how they are expanded by default when used in the Makefile:

DATADIR gets expanded to PREFIX/share/PORTNAME.
DATADIR_REL gets expanded to share/PORTNAME.
DOCSDIR gets expanded to PREFIX/share/doc/PORTNAME.
DOCSDIR_REL gets expanded to share/doc/PORTNAME.
EXAMPLESDIR gets expanded to PREFIX/share/examples/PORTNAME.
EXAMPLESDIR_REL gets expanded to share/examples/PORTNAME.

The DOCS option only controls additional documentation installed in DOCSDIR. It does not apply to standard man pages and info pages. Things installed in EXAMPLESDIR are controlled by the EXAMPLES option.

These variables are exported to PLIST_SUB. Their values will appear there as pathnames relative to PREFIX if possible. That is, share/doc/PORTNAME will be substituted for %%DOCSDIR%% in the packing list by default, and so on. (See more on pkg-plist substitution here.)

All conditionally installed documentation files and directories are included in pkg-plist with the %%PORTDOCS%% prefix, for example:

%%PORTDOCS%%%%DOCSDIR%%/AUTHORS
%%PORTDOCS%%%%DOCSDIR%%/CONTACT

As an alternative to enumerating the documentation files in pkg-plist, a port can set the variable PORTDOCS to a list of file names and shell glob patterns to add to the final packing list. The names will be relative to DOCSDIR. Therefore, a port that utilizes PORTDOCS, and uses a non-default location for its documentation, must set DOCSDIR accordingly. If a directory is listed in PORTDOCS or matched by a glob pattern from this variable, the entire subtree of contained files and directories will be registered in the final packing list. If the DOCS option has been unset then files and directories listed in PORTDOCS would not be installed or added to port packing list. Installing the documentation at PORTDOCS as shown above remains up to the port itself. A typical example of utilizing PORTDOCS:

PORTDOCS=	README.* ChangeLog docs/*

The equivalents of PORTDOCS for files installed under DATADIR and EXAMPLESDIR are PORTDATA and PORTEXAMPLES, respectively.

The contents of pkg-message are displayed upon installation. See the section on using pkg-message for details. pkg-message does not need to be added to pkg-plist.

5.17.5. Subdirectories Under `PREFIX`

Try to let the port put things in the right subdirectories of PREFIX. Some ports lump everything and put it in the subdirectory with the port’s name, which is incorrect. Also, many ports put everything except binaries, header files and manual pages in a subdirectory of lib, which does not work well with the BSD paradigm. Many of the files must be moved to one of these directories: etc (setup/configuration files), libexec (executables started internally), sbin (executables for superusers/managers), info (documentation for info browser) or share (architecture independent files). See hier(7) for details; the rules governing /usr pretty much apply to /usr/local too. The exception are ports dealing with USENET "news". They may use PREFIX/news as a destination for their files.

5.18. Use `BINARY_ALIAS` to Rename Commands Instead of Patching the Build

When BINARY_ALIAS is defined it will create symlinks of the given commands in a directory which will be prepended to PATH.

Use it to substitute hardcoded commands the build phase relies on without having to patch any build files.

Example 52. Using BINARY_ALIAS to Make gsed Available as sed

Some ports expect sed to behave like GNU sed and use features that sed(1) does not provide. GNU sed is available from textproc/gsed on FreeBSD.

Use BINARY_ALIAS to substitute sed with gsed for the duration of the build:

BUILD_DEPENDS=	gsed:textproc/gsed
...
BINARY_ALIAS=	sed=gsed

Example 53. Using BINARY_ALIAS to Provide Aliases for Hardcoded python3 Commands

A port that has a hardcoded reference to python3 in its build scripts will need to have it available in PATH at build time. Use BINARY_ALIAS to create an alias that points to the right Python 3 binary:

USES=	python:3.4+,build
...
BINARY_ALIAS=	python3=${PYTHON_CMD}

See Using Python for more information about USES=python.

Binary aliases are created after the dependencies provided via BUILD_DEPENDS and LIB_DEPENDS are processed and before the configure target. This leads to various limitations. For example, programs installed via TEST_DEPENDS cannot be used to create a binary alias as test dependencies specified this way are processed after binary aliases are created.

Chapter 6. Special Considerations

This section explains the most common things to consider when creating a port.

6.1. Splitting long files

Sometimes, port Makefiles can be really long. For example, rust ports can have a very long CARGO_CRATES list. In other cases, the Makefile might have code that varies depending on the architecture. In such cases, it can be convenient to split the original Makefile into several files. bsd.port.mk automatically includes some types of Makefiles into the main port Makefile.

These are the files that the framework handles automatically if they are found:

Makefile.crates. An example can be found in audio/ebur128.
Makefile.inc. An example can be found in net/ntp.
Makefile.${ARCH}-${OPSYS}
Makefile.${OPSYS}. An example can be found in net/cvsup-static.
Makefile.${ARCH}
Makefile.local

It is also usual practice to split the packaging list of the port into several files if the list varies a lot from one architecture to another or depends on the selected flavor. In this case, the pkg-plist file for each architecture is named following the pattern pkg-plist.${ARCH} or pkg-plist.${FLAVOR}. The framework does not create the packaging list automatically if multiple pkg-plist files exist. It is the responsibility of the porter to select the proper pkg-plist and assign it to the PLIST variable. Examples on how to deal with this can be found in audio/logitechmediaserver and deskutils/libportal.

6.2. Staging

bsd.port.mk expects ports to work with a "stage directory". This means that a port must not install files directly to the regular destination directories (that is, under PREFIX, for example) but instead into a separate directory from which the package is then built. In many cases, this does not require root privileges, making it possible to build packages as an unprivileged user. With staging, the port is built and installed into the stage directory, STAGEDIR. A package is created from the stage directory and then installed on the system. Automake tools refer to this concept as DESTDIR, but in FreeBSD, DESTDIR has a different meaning (see PREFIX and DESTDIR).

No port really needs to be root. It can mostly be avoided by using USES=uidfix. If the port still runs commands like chown(8), chgrp(1), or forces owner or group with install(1) then use USES=fakeroot to fake those calls. Some patching of the port’s Makefiles will be needed.

Meta ports, or ports that do not install files themselves but only depend on other ports, must avoid needlessly extracting the mtree(8) to the stage directory. This is the basic directory layout of the package, and these empty directories will be seen as orphans. To prevent mtree(8) extraction, add this line:

NO_MTREE=	yes

Metaports should use USES=metaport. It sets up defaults for ports that do not fetch, build, or install anything.

Staging is enabled by prepending STAGEDIR to paths used in the pre-install, do-install, and post-install targets (see the examples through the book). Typically, this includes PREFIX, ETCDIR, DATADIR, EXAMPLESDIR, DOCSDIR, and so on. Directories should be created as part of the post-install target. Avoid using absolute paths whenever possible.

Ports that install kernel modules must prepend STAGEDIR to their destination, by default /boot/modules.

6.2.1. Handling Symbolic Links

When creating a symbolic link, relative ones are strongly recommended. Use ${RLN} to create relative symbolic links. It uses install(1) under the hood to automatically figure out the relative link to create.

Example 54. Create Relative Symbolic Links Automatically

${RLN} uses install(1)'s relative symbolic feature which frees the porter of computing the relative path.

${RLN} ${STAGEDIR}${PREFIX}/lib/libfoo.so.42 ${STAGEDIR}${PREFIX}/lib/libfoo.so
${RLN} ${STAGEDIR}${PREFIX}/libexec/foo/bar ${STAGEDIR}${PREFIX}/bin/bar
${RLN} ${STAGEDIR}/var/cache/foo ${STAGEDIR}${PREFIX}/share/foo

Will generate:

% ls -lF ${STAGEDIR}${PREFIX}/lib
lrwxr-xr-x  1 nobody  nobody    181 Aug  3 11:27 libfoo.so@ -> libfoo.so.42
-rwxr-xr-x  1 nobody  nobody     15 Aug  3 11:24 libfoo.so.42*
% ls -lF ${STAGEDIR}${PREFIX}/bin
lrwxr-xr-x  1 nobody  nobody    181 Aug  3 11:27 bar@ -> ../libexec/foo/bar
% ls -lF ${STAGEDIRDIR}${PREFIX}/share
lrwxr-xr-x  1 nobody  nobody    181 Aug  3 11:27 foo@ -> ../../../var/cache/foo

6.3. Bundled Libraries

This section explains why bundled dependencies are considered bad and what to do about them.

6.3.1. Why Bundled Libraries Are Bad

Some software requires the porter to locate third-party libraries and add the required dependencies to the port. Other software bundles all necessary libraries into the distribution file. The second approach seems easier at first, but there are some serious drawbacks:

This list is loosely based on the Fedora and Gentoo wikis, both licensed under the CC-BY-SA 3.0 license.

Security: If vulnerabilities are found in the upstream library and fixed there, they might not be fixed in the library bundled with the port. One reason could be that the author is not aware of the problem. This means that the porter must fix them, or upgrade to a non-vulnerable version, and send a patch to the author. This all takes time, which results in software being vulnerable longer than necessary. This in turn makes it harder to coordinate a fix without unnecessarily leaking information about the vulnerability.
Bugs: This problem is similar to the problem with security in the last paragraph, but generally less severe.
Forking: It is easier for the author to fork the upstream library once it is bundled. While convenient on first sight, it means that the code diverges from upstream making it harder to address security or other problems with the software. A reason for this is that patching becomes harder.
Another problem of forking is that because code diverges from upstream, bugs get solved over and over again instead of just once at a central location. This defeats the idea of open source software in the first place.
Symbol collision: When a library is installed on the system, it might collide with the bundled version. This can cause immediate errors at compile or link time. It can also cause errors when running the program which might be harder to track down. The latter problem could be caused because the versions of the two libraries are incompatible.
Licensing: When bundling projects from different sources, license issues can arise more easily, especially when licenses are incompatible.
Waste of resources: Bundled libraries waste resources on several levels. It takes longer to build the actual application, especially if these libraries are already present on the system. At run-time, they can take up unnecessary memory when the system-wide library is already loaded by one program and the bundled library is loaded by another program.
Waste of effort: When a library needs patches for FreeBSD, these patches have to be duplicated again in the bundled library. This wastes developer time because the patches might not apply cleanly. It can also be hard to notice that these patches are required in the first place.

6.3.2. What to do About Bundled Libraries

Whenever possible, use the unbundled version of the library by adding a LIB_DEPENDS to the port. If such a port does not exist yet, consider creating it.

Only use bundled libraries if the upstream has a good track record on security and using unbundled versions leads to overly complex patches.

In some very special cases, for example emulators, like Wine, a port has to bundle libraries, because they are in a different architecture, or they have been modified to fit the software’s use. In that case, those libraries should not be exposed to other ports for linking. Add BUNDLE_LIBS=yes to the port’s Makefile. This will tell pkg(8) to not compute provided libraries. Always ask the Ports Management Team <portmgr@FreeBSD.org> before adding this to a port.

6.4. Shared Libraries

If the port installs one or more shared libraries, define a USE_LDCONFIG make variable, which will instruct a bsd.port.mk to run ${LDCONFIG} -m on the directory where the new library is installed (usually PREFIX/lib) during post-install target to register it into the shared library cache. This variable, when defined, will also facilitate addition of an appropriate @exec /sbin/ldconfig -m and @unexec /sbin/ldconfig -R pair into pkg-plist, so that a user who installed the package can start using the shared library immediately and de-installation will not cause the system to still believe the library is there.

USE_LDCONFIG=	yes

The default directory can be overridden by setting USE_LDCONFIG to a list of directories into which shared libraries are to be installed. For example, if the port installs shared libraries into PREFIX/lib/foo and PREFIX/lib/bar use this in Makefile:

USE_LDCONFIG=	${PREFIX}/lib/foo ${PREFIX}/lib/bar

Please double-check, often this is not necessary at all or can be avoided through -rpath or setting LD_RUN_PATH during linking (see lang/mosml for an example), or through a shell-wrapper which sets LD_LIBRARY_PATH before invoking the binary, like www/seamonkey does.

When installing 32-bit libraries on a 64-bit system, use USE_LDCONFIG32 instead.

If the software uses autotools, and specifically libtool, add USES=libtool.

When the major library version number increments in the update to the new port version, all other ports that link to the affected library must have their PORTREVISION incremented, to force recompilation with the new library version.

6.5. Ports with Distribution Restrictions or Legal Concerns

Licenses vary, and some of them place restrictions on how the application can be packaged, whether it can be sold for profit, and so on.

It is the responsibility of a porter to read the licensing terms of the software and make sure that the FreeBSD project will not be held accountable for violating them by redistributing the source or compiled binaries either via FTP/HTTP or CD-ROM. If in doubt, please contact the FreeBSD ports mailing list.

In situations like this, the variables described in the next sections can be set.

6.5.1. `NO_PACKAGE`

This variable indicates that we may not generate a binary package of the application. For instance, the license may disallow binary redistribution, or it may prohibit distribution of packages created from patched sources.

However, the port’s DISTFILES may be freely mirrored on FTP/HTTP. They may also be distributed on a CD-ROM (or similar media) unless NO_CDROM is set as well.

If the binary package is not generally useful, and the application must always be compiled from the source code, use NO_PACKAGE. For example, if the application has configuration information that is site specific hard coded into it at compile time, set NO_PACKAGE.

Set NO_PACKAGE to a string describing the reason why the package cannot be generated.

6.5.2. `NO_CDROM`

This variable alone indicates that, although we are allowed to generate binary packages, we may put neither those packages nor the port’s DISTFILES onto a CD-ROM (or similar media) for resale. However, the binary packages and the port’s DISTFILES will still be available via FTP/HTTP.

If this variable is set along with NO_PACKAGE, then only the port’s DISTFILES will be available, and only via FTP/HTTP.

Set NO_CDROM to a string describing the reason why the port cannot be redistributed on CD-ROM. For instance, use this if the port’s license is for "non-commercial" use only.

6.5.3. `NOFETCHFILES`

Files defined in NOFETCHFILES are not fetchable from any of MASTER_SITES. An example of such a file is when the file is supplied on CD-ROM by the vendor.

Tools which check for the availability of these files on MASTER_SITES have to ignore these files and not report about them.

6.5.4. `RESTRICTED`

Set this variable alone if the application’s license permits neither mirroring the application’s DISTFILES nor distributing the binary package in any way.

Do not set NO_CDROM or NO_PACKAGE along with RESTRICTED, since the latter variable implies the former ones.

Set RESTRICTED to a string describing the reason why the port cannot be redistributed. Typically, this indicates that the port contains proprietary software and that the user will need to manually download the DISTFILES, possibly after registering for the software or agreeing to accept the terms of an EULA.

6.5.5. `RESTRICTED_FILES`

When RESTRICTED or NO_CDROM is set, this variable defaults to ${DISTFILES} ${PATCHFILES}, otherwise it is empty. If only some of the distribution files are restricted, then set this variable to list them.

6.5.6. `LEGAL_TEXT`

If the port has legal concerns not addressed by the above variables, set LEGAL_TEXT to a string explaining the concern. For example, if special permission was obtained for FreeBSD to redistribute the binary, this variable must indicate so.

6.5.7. /usr/ports/LEGAL and `LEGAL`

A port which sets any of the above variables must also be added to /usr/ports/LEGAL. The first column is a glob which matches the restricted distfiles. The second column is the port’s origin. The third column is the output of make -VLEGAL.

6.5.8. Examples

The preferred way to state "the distfiles for this port must be fetched manually" is as follows:

.if !exists(${DISTDIR}/${DISTNAME}${EXTRACT_SUFX})
IGNORE=	may not be redistributed because of licensing reasons. Please visit some-website to accept their license and download ${DISTFILES} into ${DISTDIR}
.endif

This both informs the user, and sets the proper metadata on the user’s machine for use by automated programs.

Note that this stanza must be preceded by an inclusion of bsd.port.pre.mk.

6.6. Building Mechanisms

6.6.1. Building Ports in Parallel

The FreeBSD ports framework supports parallel building using multiple make sub-processes, which allows SMP systems to utilize all of their available CPU power, allowing port builds to be faster and more effective.

This is achieved by passing -jX flag to make(1) running on vendor code. This is the default build behavior of ports. Unfortunately, not all ports handle parallel building well and it may be required to explicitly disable this feature by adding the MAKE_JOBS_UNSAFE=yes variable. It is used when a port is known to be broken with -jX due to race conditions causing intermittent build failures.

When setting MAKE_JOBS_UNSAFE, it is very important to explain either with a comment in the Makefile, or at least in the commit message, why the port does not build when enabling. Otherwise, it is almost impossible to either fix the problem, or test if it has been fixed when committing an update at a later date.

6.6.2. `make`, `gmake`, and `imake`

Several differing make implementations exist. Ported software often requires a particular implementation, like GNU make, known in FreeBSD as gmake.

If the port uses GNU make, add gmake to USES.

MAKE_CMD can be used to reference the specific command configured by the USES setting in the port’s Makefile. Only use MAKE_CMD within the application Makefiles in WRKSRC to call the make implementation expected by the ported software.

If the port is an X application that uses imake to create Makefiles from Imakefiles, set USES= imake. See the USES=imake section of Using USES Macros for more details.

If the port’s source Makefile has something other than all as the main build target, set ALL_TARGET accordingly. The same goes for install and INSTALL_TARGET.

6.6.3. `configure` Script

If the port uses the configure script to generate Makefile from Makefile.in, set GNU_CONFIGURE=yes. To give extra arguments to the configure script (the default argument is --prefix=${PREFIX} --infodir=${PREFIX}/${INFO_PATH} --mandir=${PREFIX}/man --build=${CONFIGURE_TARGET}), set those extra arguments in CONFIGURE_ARGS. Extra environment variables can be passed using CONFIGURE_ENV.

Table 9. Variables for Ports That Use `configure`
Variable	Means
`GNU_CONFIGURE`	The port uses `configure` script to prepare build.
`HAS_CONFIGURE`	Same as `GNU_CONFIGURE`, except default configure target is not added to `CONFIGURE_ARGS`.
`CONFIGURE_ARGS`	Additional arguments passed to `configure` script.
`CONFIGURE_ENV`	Additional environment variables to be set for `configure` script run.
`CONFIGURE_TARGET`	Override default configure target. Default value is `${MACHINE_ARCH}-portbld-freebsd${OSREL}`.

6.6.4. Using `cmake`

For ports that use CMake, define USES= cmake.

Table 10. Variables for Ports That Use `cmake`
Variable	Means
`CMAKE_ARGS`	Port specific CMake flags to be passed to the `cmake` binary.
`CMAKE_ON`	For each entry in `CMAKE_ON`, an enabled boolean value is added to `CMAKE_ARGS`. See `CMAKE_ON` and `CMAKE_OFF`.
`CMAKE_OFF`	For each entry in `CMAKE_OFF`, a disabled boolean value is added to `CMAKE_ARGS`. See `CMAKE_ON` and `CMAKE_OFF`.
`CMAKE_BUILD_TYPE`	Type of build (CMake predefined build profiles). Default is `Release`, or `Debug` if `WITH_DEBUG` is set.
`CMAKE_SOURCE_PATH`	Path to the source directory. Default is `${WRKSRC}`.
`CONFIGURE_ENV`	Additional environment variables to be set for the `cmake` binary.

Table 11. Variables the Users Can Define for `cmake` Builds
Variable	Means
`CMAKE_NOCOLOR`	Disables color build output. Default not set, unless `BATCH` or `PACKAGE_BUILDING` are set.

CMake supports these build profiles: Debug, Release, RelWithDebInfo and MinSizeRel. Debug and Release profiles respect system *FLAGS, RelWithDebInfo and MinSizeRel will set CFLAGS to -O2 -g and -Os -DNDEBUG correspondingly. The lower-cased value of CMAKE_BUILD_TYPE is exported to PLIST_SUB and must be used if the port installs *.cmake depending on the build type (see devel/kf5-kcrash for an example). Please note that some projects may define their own build profiles and/or force particular build type by setting CMAKE_BUILD_TYPE in CMakeLists.txt. To make a port for such a project respect CFLAGS and WITH_DEBUG, the CMAKE_BUILD_TYPE definitions must be removed from those files.

Most CMake-based projects support an out-of-source method of building. The out-of-source build for a port is the default setting. An in-source build can be requested by using the :insource suffix. With out-of-source builds, CONFIGURE_WRKSRC, BUILD_WRKSRC and INSTALL_WRKSRC will be set to ${WRKDIR}/.build and this directory will be used to keep all files generated during configuration and build stages, leaving the source directory intact.

Example 55. USES= cmake Example

This snippet demonstrates the use of CMake for a port. CMAKE_SOURCE_PATH is not usually required, but can be set when the sources are not located in the top directory, or if only a subset of the project is intended to be built by the port.

USES=			cmake
CMAKE_SOURCE_PATH=	${WRKSRC}/subproject

Example 56. CMAKE_ON and CMAKE_OFF

When adding boolean values to CMAKE_ARGS, it is easier to use the CMAKE_ON and CMAKE_OFF variables instead. This:

CMAKE_ON=	VAR1 VAR2
CMAKE_OFF=	VAR3

Is equivalent to:

CMAKE_ARGS=	-DVAR1:BOOL=TRUE -DVAR2:BOOL=TRUE -DVAR3:BOOL=FALSE

This is only for the default values off CMAKE_ARGS. The helpers described in OPT_CMAKE_BOOL and OPT_CMAKE_BOOL_OFF use the same semantics, but for optional values.

6.6.5. Using `scons`

If the port uses SCons, define USES=scons.

To make third party SConstruct respect everything that is passed to SCons in the environment (that is, most importantly, CC/CXX/CFLAGS/CXXFLAGS), patch SConstruct so build Environment is constructed like this:

env = Environment(**ARGUMENTS)

It may be then modified with env.Append and env.Replace.

6.6.6. Building Rust Applications with `cargo`

For ports that use Cargo, define USES=cargo.

Table 12. Variables the Users Can Define for `cargo` Builds
Variable	Default	Description
`CARGO_CRATES`		List of crates the port depends on. Each entry needs to have a format like `cratename-semver` for example, `libc-0.2.40`. Port maintainers can generate this list from Cargo.lock using `make cargo-crates`. Manually bumping crate versions is possible but be mindful of transitive dependencies. If the list generated by `make cargo-crates` is big, it might be convenient to place it inside a `Makefile.crates` file in the top-level port directory. If present, the ports framework sources that file automatically. This help keep the main port Makefile within a manageable size.
`CARGO_FEATURES`		List of application features to build (space separated list). To deactivate all default features add the special token `--no-default-features` to `CARGO_FEATURES`. Manually passing it to `CARGO_BUILD_ARGS`, `CARGO_INSTALL_ARGS`, and `CARGO_TEST_ARGS` is not needed.
`CARGO_CARGOTOML`	`${WRKSRC}/Cargo.toml`	The path to the Cargo.toml to use.
`CARGO_CARGOLOCK`	`${WRKSRC}/Cargo.lock`	The path to the Cargo.lock to use for `make cargo-crates`. It is possible to specify more than one lock file when necessary.
`CARGO_ENV`		A list of environment variables to pass to Cargo similar to `MAKE_ENV`.
`RUSTFLAGS`		Flags to pass to the Rust compiler.
`CARGO_CONFIGURE`	`yes`	Use the default `do-configure`.
`CARGO_UPDATE_ARGS`		Extra arguments to pass to Cargo during the configure phase. Valid arguments can be looked up with `cargo update --help`.
`CARGO_BUILDDEP`	`yes`	Add a build dependency on lang/rust.
`CARGO_CARGO_BIN`	`${LOCALBASE}/bin/cargo`	Location of the `cargo` binary.
`CARGO_BUILD`	`yes`	Use the default `do-build`.
`CARGO_BUILD_ARGS`		Extra arguments to pass to Cargo during the build phase. Valid arguments can be looked up with `cargo build --help`.
`CARGO_INSTALL`	`yes`	Use the default `do-install`.
`CARGO_INSTALL_ARGS`		Extra arguments to pass to Cargo during the install phase. Valid arguments can be looked up with `cargo install --help`.
`CARGO_INSTALL_PATH`	`.`	Path to the crate to install. This is passed to `cargo install` via its `--path` argument. When multiple paths are specified `cargo install` is run multiple times.
`CARGO_TEST`	`yes`	Use the default `do-test`.
`CARGO_TEST_ARGS`		Extra arguments to pass to Cargo during the test phase. Valid arguments can be looked up with `cargo test --help`.
`CARGO_TARGET_DIR`	`${WRKDIR}/target`	Location of the cargo output directory.
`CARGO_DIST_SUBDIR`	rust/crates	Directory relative to `DISTDIR` where the crate distribution files will be stored.
`CARGO_VENDOR_DIR`	`${WRKSRC}/cargo-crates`	Location of the vendor directory where all crates will be extracted to. Try to keep this under `PATCH_WRKSRC`, so that patches can be applied easily.
`CARGO_USE_GITHUB`	`no`	Enable fetching of crates locked to specific Git commits on GitHub via `GH_TUPLE`. This will try to patch all Cargo.toml under `WRKDIR` to point to the offline sources instead of fetching them from a Git repository during the build.
`CARGO_USE_GITLAB`	`no`	Same as `CARGO_USE_GITHUB` but for GitLab instances and `GL_TUPLE`.

Example 57. Creating a Port for a Simple Rust Application

Creating a Cargo based port is a three stage process. First we need to provide a ports template that fetches the application distribution file:

PORTNAME=	tokei
DISTVERSIONPREFIX=	v
DISTVERSION=	7.0.2
CATEGORIES=	devel

MAINTAINER=	tobik@FreeBSD.org
COMMENT=	Display statistics about your code
WWW=		https://github.com/XAMPPRocky/tokei/

USES=		cargo
USE_GITHUB=	yes
GH_ACCOUNT=	Aaronepower

.include <bsd.port.mk>

Generate an initial distinfo:

% make makesum
=> Aaronepower-tokei-v7.0.2_GH0.tar.gz doesn't seem to exist in /usr/ports/distfiles/.
=> Attempting to fetch https://codeload.github.com/Aaronepower/tokei/tar.gz/v7.0.2?dummy=/Aaronepower-tokei-v7.0.2_GH0.tar.gz
fetch: https://codeload.github.com/Aaronepower/tokei/tar.gz/v7.0.2?dummy=/Aaronepower-tokei-v7.0.2_GH0.tar.gz: size of remote file is not known
Aaronepower-tokei-v7.0.2_GH0.tar.gz                     45 kB  239 kBps 00m00s

Now the distribution file is ready to use and we can go ahead and extract crate dependencies from the bundled Cargo.lock:

% make cargo-crates
CARGO_CRATES=   aho-corasick-0.6.4 \
                ansi_term-0.11.0 \
                arrayvec-0.4.7 \
                atty-0.2.9 \
                bitflags-1.0.1 \
                byteorder-1.2.2 \
                [...]

The output of this command needs to be pasted directly into the Makefile:

PORTNAME=	tokei
DISTVERSIONPREFIX=	v
DISTVERSION=	7.0.2
CATEGORIES=	devel

MAINTAINER=	tobik@FreeBSD.org
COMMENT=	Display statistics about your code
WWW=		https://github.com/XAMPPRocky/tokei/

USES=		cargo
USE_GITHUB=	yes
GH_ACCOUNT=	Aaronepower

CARGO_CRATES=   aho-corasick-0.6.4 \
                ansi_term-0.11.0 \
                arrayvec-0.4.7 \
                atty-0.2.9 \
                bitflags-1.0.1 \
                byteorder-1.2.2 \
                [...]

.include <bsd.port.mk>

distinfo needs to be regenerated to contain all the crate distribution files:

% make makesum
=> rust/crates/aho-corasick-0.6.4.tar.gz doesn't seem to exist in /usr/ports/distfiles/.
=> Attempting to fetch https://crates.io/api/v1/crates/aho-corasick/0.6.4/download?dummy=/rust/crates/aho-corasick-0.6.4.tar.gz

=> rust/crates/bitflags-1.0.1.tar.gz doesn't seem to exist in /usr/ports/distfiles/.
[...]

The port is now ready for a test build and further adjustments like creating a plist, writing a description, adding license information, options, etc. as normal.

If you are not testing your port in a clean environment like with poudriere, remember to run make clean before any testing.

Example 58. Enabling Additional Application Features

Some applications define additional features in their Cargo.toml. They can be compiled in by setting CARGO_FEATURES in the port.

Here we enable Tokei’s json and yaml features:

CARGO_FEATURES=	json yaml

Example 59. Encoding Application Features As Port Options

An example [features] section in Cargo.toml could look like this:

[features]
pulseaudio_backend = ["librespot-playback/pulseaudio-backend"]
portaudio_backend = ["librespot-playback/portaudio-backend"]
default = ["pulseaudio_backend"]

pulseaudio_backend is a default feature. It is always enabled unless we explicitly turn off default features by adding --no-default-features to CARGO_FEATURES. Here we turn the portaudio_backend and pulseaudio_backend features into port options:

CARGO_FEATURES=	--no-default-features

OPTIONS_DEFINE=	PORTAUDIO PULSEAUDIO

PORTAUDIO_VARS=		CARGO_FEATURES+=portaudio_backend
PULSEAUDIO_VARS=	CARGO_FEATURES+=pulseaudio_backend

Example 60. Listing Crate Licenses

Crates have their own licenses. It is important to know what they are when adding a LICENSE block to the port (see Licenses). The helper target cargo-crates-licenses will try to list all the licenses of all crates defined in CARGO_CRATES.

% make cargo-crates-licenses
aho-corasick-0.6.4  Unlicense/MIT
ansi_term-0.11.0    MIT
arrayvec-0.4.7      MIT/Apache-2.0
atty-0.2.9          MIT
bitflags-1.0.1      MIT/Apache-2.0
byteorder-1.2.2     Unlicense/MIT
[...]

The license names make cargo-crates-licenses outputs are SPDX 2.1 licenses expression which do not match the license names defined in the ports framework. They need to be translated to the names from Predefined License List.

6.6.7. Using `meson`

For ports that use Meson, define USES=meson.

Table 13. Variables for Ports That Use `meson`
Variable	Description
`MESON_ARGS`	Port specific Meson flags to be passed to the `meson` binary.
`MESON_BUILD_DIR`	Path to the build directory relative to `WRKSRC`. Default is `_build`.

Example 61. USES=meson Example

This snippet demonstrates the use of Meson for a port.

USES=		meson
MESON_ARGS=	-Dfoo=enabled

6.6.8. Building Go Applications

For ports that use Go, define USES=go. Refer to go for a list of variables that can be set to control the build process.

Example 62. Creating a Port for a Go Modules Based Application

In most cases, it is sufficient to set the GO_MODULE variable to the value specified by the module directive in go.mod:

PORTNAME=       hey
DISTVERSIONPREFIX=	v
DISTVERSION=    0.1.4
CATEGORIES=     benchmarks

MAINTAINER=     dmgk@FreeBSD.org
COMMENT=        Tiny program that sends some load to a web application
WWW=            https://github.com/rakyll/hey/

LICENSE=        APACHE20
LICENSE_FILE=   ${WRKSRC}/LICENSE

USES=           go:modules
GO_MODULE=      github.com/rakyll/hey

PLIST_FILES=    bin/hey

.include <bsd.port.mk>

If the "easy" way is not adequate or more control over dependencies is needed, the full porting process is described below.

Creating a Go-based port is a five-stage process. First we need to provide a ports template that fetches the application distribution file:

PORTNAME=	ghq
DISTVERSIONPREFIX=	v
DISTVERSION=	0.12.5
CATEGORIES=	devel

MAINTAINER=	tobik@FreeBSD.org
COMMENT=	Remote repository management made easy
WWW=		https://github.com/x-motemen/ghq/

USES=		go:modules
USE_GITHUB=	yes
GH_ACCOUNT=	motemen

.include <bsd.port.mk>

Generate an initial distinfo:

% make makesum
===>  License MIT accepted by the user
=> motemen-ghq-v0.12.5_GH0.tar.gz doesn't seem to exist in /usr/ports/distfiles/.
=> Attempting to fetch https://codeload.github.com/motemen/ghq/tar.gz/v0.12.5?dummy=/motemen-ghq-v0.12.5_GH0.tar.gz
fetch: https://codeload.github.com/motemen/ghq/tar.gz/v0.12.5?dummy=/motemen-ghq-v0.12.5_GH0.tar.gz: size of remote file is not known
motemen-ghq-v0.12.5_GH0.tar.gz                          32 kB  177 kBps    00s

Now the distribution file is ready to use and we can extract the required Go module dependencies. This step requires having ports-mgmt/modules2tuple installed:

% make gomod-vendor
[...]
GH_TUPLE=	\
		Songmu:gitconfig:v0.0.2:songmu_gitconfig/vendor/github.com/Songmu/gitconfig \

The output of this command needs to be pasted directly into the Makefile:

.include <bsd.port.mk>

distinfo needs to be regenerated to contain all the distribution files:

[...]

The port is now ready for a test build and further adjustments like creating a plist, writing a description, adding license information, options, etc. as normal.

If you are not testing your port in a clean environment like with poudriere, remember to run make clean before any testing.

Example 63. Setting Output Binary Name or Installation Path

Some ports need to install the resulting binary under a different name or to a path other than the default ${PREFIX}/bin. This can be done by using GO_TARGET tuple syntax, for example:

GO_TARGET=  ./cmd/ipfs:ipfs-go

will install ipfs binary as ${PREFIX}/bin/ipfs-go and

GO_TARGET=  ./dnscrypt-proxy:${PREFIX}/sbin/dnscrypt-proxy

will install dnscrypt-proxy to ${PREFIX}/sbin.

6.6.9. Building Haskell Applications with `cabal`

For ports that use Cabal, build system defines USES=cabal. Refer to cabal for a list of variables that can be set to control the build process.

Example 64. Creating a Port for a Hackage-hosted Haskell Application

When preparing a Haskell Cabal port, devel/hs-cabal-install and ports-mgmt/hs-cabal2tuple programs are required, so make sure they are installed beforehand. First we need to define common ports variables that allow cabal-install to fetch the package distribution file:

PORTNAME=	ShellCheck
DISTVERSION=	0.6.0
CATEGORIES=	devel

MAINTAINER=	haskell@FreeBSD.org
COMMENT=	Shell script analysis tool
WWW=		https://www.shellcheck.net/

USES=		cabal

.include <bsd.port.mk>

This minimal Makefile fetches the distribution file with the cabal-extract helper target:

% make cabal-extract
[...]
Downloading the latest package list from hackage.haskell.org
cabal get ShellCheck-0.6.0
Downloading  ShellCheck-0.6.0
Downloaded   ShellCheck-0.6.0
Unpacking to ShellCheck-0.6.0/

Now that we have ShellCheck.cabal package description file under ${WRKSRC}, we can use cabal-configure to generate the build plan:

% make cabal-configure
[...]
Resolving dependencies...
Build profile: -w ghc-8.10.7 -O1
In order, the following would be built (use -v for more details):
 - Diff-0.4.1 (lib) (requires download & build)
 - OneTuple-0.3.1 (lib) (requires download & build)
[...]

Once done, a list of required dependencies can generated:

% make make-use-cabal
USE_CABAL=	QuickCheck-2.12.6.1 \
		hashable-1.3.0.0 \
		integer-logarithms-1.0.3 \
[...]

Haskell packages may contain revisions, just like FreeBSD ports. Revisions can affect .cabal files only. Note additional version numbers after the _ symbol. Put newly generated USE_CABAL list instead of an old one.

Finally, distinfo needs to be regenerated to contain all the distribution files:

% make makesum
=> ShellCheck-0.6.0.tar.gz doesn't seem to exist in /usr/local/poudriere/ports/git/distfiles/cabal.
=> Attempting to fetch https://hackage.haskell.org/package/ShellCheck-0.6.0/ShellCheck-0.6.0.tar.gz
ShellCheck-0.6.0.tar.gz                                136 kB  642 kBps    00s
=> QuickCheck-2.12.6.1/QuickCheck-2.12.6.1.tar.gz doesn't seem to exist in /usr/local/poudriere/ports/git/distfiles/cabal.
=> Attempting to fetch https://hackage.haskell.org/package/QuickCheck-2.12.6.1/QuickCheck-2.12.6.1.tar.gz
QuickCheck-2.12.6.1/QuickCheck-2.12.6.1.tar.gz          65 kB  361 kBps    00s
[...]

The port is now ready for a test build and further adjustments like creating a plist, writing a description, adding license information, options, etc. as normal.

If you are not testing your port in a clean environment like with poudriere, remember to run make clean before any testing.

Some Haskell ports install various data files under share/${PORTNAME}. For such cases special handling is required on the port side. The port should define the CABAL_WRAPPER_SCRIPTS knob listing each executable that is going to use data files. Moreover, in rare cases the program being ported uses data files of other Haskell packages, in which case the FOO_DATADIR_VARS comes to the rescue.

Example 65. Handling Data Files in a Haskell Port

devel/hs-profiteur is a Haskell application that generates a single-page HTML with some content.

PORTNAME=	profiteur

[...]

USES=		cabal

USE_CABAL=	OneTuple-0.3.1_2 \
		QuickCheck-2.14.2 \
		[...]

.include <bsd.port.mk>

It installs HTML templates under share/profiteur, so we need to add CABAL_WRAPPER_SCRIPTS knob:

[...]

USE_CABAL=	OneTuple-0.3.1_2 \
		QuickCheck-2.14.2 \
		[...]


CABAL_WRAPPER_SCRIPTS=		${CABAL_EXECUTABLES}

.include <bsd.port.mk>

The program also tries to access the jquery.js file, which is a part of js-jquery-3.3.1 Haskell package. For that file to be found, we need to make the wrapper script to look for js-jquery data files in share/profiteur too. We use profiteur_DATADIR_VARS for this:

[...]

CABAL_WRAPPER_SCRIPTS=		${CABAL_EXECUTABLES}
profiteur_DATADIR_VARS=		js-jquery

.include <bsd.port.mk>

Now the port will install the actual binary into libexec/cabal/profiteur and the script into bin/profiteur.

There is no easy way to find out a proper value for the FOO_DATADIR_VARS knob apart from running the program and checking that everything works. Luckily, the need to use FOO_DATADIR_VARS is very rare.

Another corner case when porting complex Haskell programs is the presence of VCS dependencies in the cabal.project file.

Example 66. Porting Haskell Applications with VCS Dependencies

net-p2p/cardano-node is an extremely complex piece of software. In its cabal.project there are a lot of blocks like this:

[...]
source-repository-package
  type: git
  location: https://github.com/input-output-hk/cardano-crypto
  tag: f73079303f663e028288f9f4a9e08bcca39a923e
[...]

Dependencies of type source-repository-package are automatically pulled in by cabal during the build process. Unfortunately, this makes use of the network after the fetch stage. This is disallowed by the ports framework. These sources need to be listed in the port’s Makefile. The make-use-cabal helper target can make it easy for packages hosted on GitHub. Running this target after the usual cabal-extract and cabal-configure will produce not only the USE_CABAL knob, but also GH_TUPLE:

% make make-use-cabal
USE_CABAL=	Diff-0.4.1 \
		Glob-0.10.2_3 \
		HUnit-1.6.2.0 \
		[...]

GH_TUPLE=		input-output-hk:cardano-base:0f3a867493059e650cda69e20a5cbf1ace289a57:cardano_base/dist-newstyle/src/cardano-b_-c8db9876882556ed \
		input-output-hk:cardano-crypto:f73079303f663e028288f9f4a9e08bcca39a923e:cardano_crypto/dist-newstyle/src/cardano-c_-253fd88117badd8f \
		[...]

It might be useful to separate the GH_TUPLE items coming from make-use-cabal from the other ones to make it easy to update the port:

GH_TUPLE=	input-output-hk:cardano-base:0f3a867493059e650cda69e20a5cbf1ace289a57:cardano_base/dist-newstyle/src/cardano-b_-c8db9876882556ed \
		input-output-hk:cardano-crypto:f73079303f663e028288f9f4a9e08bcca39a923e:cardano_crypto/dist-newstyle/src/cardano-c_-253fd88117badd8f \
		[...]

GH_TUPLE+=	bitcoin-core:secp256k1:ac83be33d0956faf6b7f61a60ab524ef7d6a473a:secp

Haskell ports with VCS dependencies also require the following hack for the time being:

BINARY_ALIAS=	git=true

6.7. Using GNU Autotools

If a port needs any of the GNU Autotools software, add USES=autoreconf. See autoreconf for more information.

6.8. Using GNU `gettext`

6.8.1. Basic Usage

If the port requires gettext, set USES= gettext, and the port will inherit a dependency on libintl.so from devel/gettext. Other values for gettext usage are listed in USES=gettext.

A rather common case is a port using gettext and configure. Generally, GNU configure should be able to locate gettext automatically.

USES=	gettext
GNU_CONFIGURE=	yes

If it ever fails to, hints at the location of gettext can be passed in CPPFLAGS and LDFLAGS using localbase as follows:

USES=	gettext localbase:ldflags
GNU_CONFIGURE=	yes

6.8.2. Optional Usage

Some software products allow for disabling NLS. For example, through passing --disable-nls to configure. In that case, the port must use gettext conditionally, depending on the status of the NLS option. For ports of low to medium complexity, use this idiom:

GNU_CONFIGURE=		yes

OPTIONS_DEFINE=		NLS
OPTIONS_SUB=		yes

NLS_USES=		gettext
NLS_CONFIGURE_ENABLE=	nls

.include <bsd.port.mk>

Or using the older way of using options:

GNU_CONFIGURE=		yes

OPTIONS_DEFINE=		NLS

.include <bsd.port.options.mk>

.if ${PORT_OPTIONS:MNLS}
USES+=			gettext
PLIST_SUB+=		NLS=""
.else
CONFIGURE_ARGS+=	--disable-nls
PLIST_SUB+=		NLS="@comment "
.endif

.include <bsd.port.mk>

The next item on the to-do list is to arrange so that the message catalog files are included in the packing list conditionally. The Makefile part of this task is already provided by the idiom. It is explained in the section on advanced pkg-plist practices. In a nutshell, each occurrence of %%NLS%% in pkg-plist will be replaced by "`@comment " if NLS is disabled, or by a null string if NLS is enabled. Consequently, the lines prefixed by `%%NLS%% will become mere comments in the final packing list if NLS is off; otherwise the prefix will be just left out. Then insert %%NLS%% before each path to a message catalog file in pkg-plist. For example:

%%NLS%%share/locale/fr/LC_MESSAGES/foobar.mo
%%NLS%%share/locale/no/LC_MESSAGES/foobar.mo

In high complexity cases, more advanced techniques may be needed, such as dynamic packing list generation.

6.8.3. Handling Message Catalog Directories

There is a point to note about installing message catalog files. The target directories for them, which reside under LOCALBASE/share/locale, must not be created and removed by a port. The most popular languages have their respective directories listed in PORTSDIR/Templates/BSD.local.dist. The directories for many other languages are governed by the devel/gettext port. Consult its pkg-plist and see whether the port is going to install a message catalog file for a unique language.

6.9. Using Perl

If MASTER_SITES is set to CPAN, the correct subdirectory is usually selected automatically. If the default subdirectory is wrong, CPAN/Module can be used to change it. MASTER_SITES can also be set to the old MASTER_SITE_PERL_CPAN, then the preferred value of MASTER_SITE_SUBDIR is the top-level hierarchy name. For example, the recommended value for p5-Module-Name is Module. The top-level hierarchy can be examined at cpan.org. This keeps the port working when the author of the module changes.

The exception to this rule is when the relevant directory does not exist or the distfile does not exist in that directory. In such case, using author’s id as MASTER_SITE_SUBDIR is allowed. The CPAN:AUTHOR macro can be used, which will be translated to the hashed author directory. For example, CPAN:AUTHOR will be converted to authors/id/A/AU/AUTHOR.

When a port needs Perl support, it must set USES=perl5 with the optional USE_PERL5 described in the perl5 USES description.

`PERL`	The full path of the Perl 5 interpreter, either in the system or installed from a port, but without the version number. Use this when the software needs the path to the Perl interpreter. To replace "`#!`"lines in scripts, use `shebangfix`.
`PERL_VERSION`	The full version of Perl installed (for example, `5.8.9`).
`PERL_LEVEL`	The installed Perl version as an integer of the form `MNNNPP` (for example, `500809`).
`PERL_ARCH`	Where Perl stores architecture dependent libraries. Defaults to `${ARCH}-freebsd`.
`PERL_PORT`	Name of the Perl port that is installed (for example, `perl5`).
`SITE_PERL`	Directory name where site specific Perl packages go. This value is added to `PLIST_SUB`.

Ports of Perl modules which do not have an official website must link to cpan.org in the WWW line of Makefile. The preferred URL form is https://search.cpan.org/dist/Module-Name/ (including the trailing slash).

Do not use ${SITE_PERL} in dependency declarations. Doing so assumes that perl5.mk has been included, which is not always true. Ports depending on this port will have incorrect dependencies if this port’s files move later in an upgrade. The right way to declare Perl module dependencies is shown in the example below.

Example 67. Perl Dependency Example

p5-IO-Tee>=0.64:devel/p5-IO-Tee

For Perl ports that install manual pages, the macro PERL5_MAN3 and PERL5_MAN1 can be used inside pkg-plist. For example,

lib/perl5/5.14/man/man1/event.1.gz
lib/perl5/5.14/man/man3/AnyEvent::I3.3.gz

can be replaced with

%%PERL5_MAN1%%/event.1.gz
%%PERL5_MAN3%%/AnyEvent::I3.3.gz

There are no PERL5_MAN_x_ macros for the other sections (x in 2 and 4 to 9) because those get installed in the regular directories.

Example 68. A Port Which Only Requires Perl to Build

As the default USE_PERL5 value is build and run, set it to:

USES=		perl5
USE_PERL5=	build

Example 69. A Port Which Also Requires Perl to Patch

From time to time, using sed(1) for patching is not enough. When using perl(1) is easier, use:

USES=		perl5
USE_PERL5=	patch build run

Example 70. A Perl Module Which Needs ExtUtils::MakeMaker to Build

Most Perl modules come with a Makefile.PL configure script. In this case, set:

USES=		perl5
USE_PERL5=	configure

Example 71. A Perl Module Which Needs Module::Build to Build

When a Perl module comes with a Build.PL configure script, it can require Module::Build, in which case, set

USES=		perl5
USE_PERL5=	modbuild

If it instead requires Module::Build::Tiny, set

USES=		perl5
USE_PERL5=	modbuildtiny

6.10. Using X11

6.10.1. X.Org Components

The X11 implementation available in The Ports Collection is X.Org. If the application depends on X components, add USES= xorg and set USE_XORG to the list of required components. A full list can be found in xorg.

The Mesa Project is an effort to provide free OpenGL implementation. To specify a dependency on various components of this project, use USES= gl and USE_GL. See gl for a full list of available components. For backwards compatibility, the value of yes maps to glu.

Example 72. USE_XORG Example

USES=		gl xorg
USE_GL=		glu
USE_XORG=	xrender xft xkbfile xt xaw

Table 15. Variables for Ports That Use X
`USES= imake`	The port uses `imake`.
`XMKMF`	Set to the path of `xmkmf` if not in the `PATH`. Defaults to `xmkmf -a`.

Example 73. Using X11-Related Variables

# Use some X11 libraries
USES=		xorg
USE_XORG=	x11 xpm

6.10.2. Ports That Require Motif

If the port requires a Motif library, define USES= motif in the Makefile. Default Motif implementation is x11-toolkits/open-motif. Users can choose x11-toolkits/lesstif instead by setting WANT_LESSTIF in their make.conf. Similarly x11-toolkits/open-motif-devel can be chosen by setting WANT_OPEN_MOTIF_DEVEL in make.conf.

MOTIFLIB will be set by motif.mk to reference the appropriate Motif library. Please patch the source of the port to use ${MOTIFLIB} wherever the Motif library is referenced in the original Makefile or Imakefile.

There are two common cases:

If the port refers to the Motif library as -lXm in its Makefile or Imakefile, substitute ${MOTIFLIB} for it.
If the port uses XmClientLibs in its Imakefile, change it to ${MOTIFLIB} ${XTOOLLIB} ${XLIB}.

Note that MOTIFLIB (usually) expands to -L/usr/local/lib -lXm -lXp or /usr/local/lib/libXm.a, so there is no need to add -L or -l in front.

6.10.3. X11 Fonts

If the port installs fonts for the X Window System, put them in LOCALBASE/lib/X11/fonts/local.

6.10.4. Getting a Fake `DISPLAY` with Xvfb

Some applications require a working X11 display for compilation to succeed. This poses a problem for machines that operate headless. When this variable is used, the build infrastructure will start the virtual framebuffer X server. The working DISPLAY is then passed to the build. See USES=display for the possible arguments.

USES=	display

6.10.5. Desktop Entries

Desktop entries (a Freedesktop standard) provide a way to automatically adjust desktop features when a new program is installed, without requiring user intervention. For example, newly-installed programs automatically appear in the application menus of compatible desktop environments. Desktop entries originated in the GNOME desktop environment, but are now a standard and also work with KDE and Xfce. This bit of automation provides a real benefit to the user, and desktop entries are encouraged for applications which can be used in a desktop environment.

6.10.5.1. Using Predefined .desktop Files

Ports that include predefined *.desktop must include those files in pkg-plist and install them in the $LOCALBASE/share/applications directory. The INSTALL_DATA macro is useful for installing these files.

6.10.5.2. Updating Desktop Database

If a port has a MimeType entry in its portname.desktop, the desktop database must be updated after install and deinstall. To do this, define USES= desktop-file-utils.

6.10.5.3. Creating Desktop Entries with `DESKTOP_ENTRIES`

Desktop entries can be easily created for applications by using DESKTOP_ENTRIES. A file named name.desktop will be created, installed, and added to pkg-plist automatically. Syntax is:

DESKTOP_ENTRIES=	"NAME" "COMMENT" "ICON" "COMMAND" "CATEGORY" StartupNotify

The list of possible categories is available on the Freedesktop website. StartupNotify indicates whether the application is compatible with startup notifications. These are typically a graphic indicator like a clock that appear at the mouse pointer, menu, or panel to give the user an indication when a program is starting. A program that is compatible with startup notifications clears the indicator after it has started. Programs that are not compatible with startup notifications would never clear the indicator (potentially confusing and infuriating the user), and must have StartupNotify set to false so the indicator is not shown at all.

Example:

DESKTOP_ENTRIES=	"ToME" "Roguelike game based on JRR Tolkien's work" \
			"${DATADIR}/xtra/graf/tome-128.png" \
			"tome -v -g" "Application;Game;RolePlaying;" \
			false

DESKTOP_ENTRIES are installed in the directory pointed to by the DESKTOPDIR variable. DESKTOPDIR defaults to ${PREFIX}/share/applications

6.11. Using GNOME

6.11.1. Introduction

This chapter explains the GNOME framework as used by ports. The framework can be loosely divided into the base components, GNOME desktop components, and a few special macros that simplify the work of port maintainers.

6.11.2. Using `USE_GNOME`

Adding this variable to the port allows the use of the macros and components defined in bsd.gnome.mk. The code in bsd.gnome.mk adds the needed build-time, run-time or library dependencies or the handling of special files. GNOME applications under FreeBSD use the USE_GNOME infrastructure. Include all the needed components as a space-separated list. The USE_GNOME components are divided into these virtual lists: basic components, GNOME 3 components and legacy components. If the port needs only GTK3 libraries, this is the shortest way to define it:

USE_GNOME=	gtk30

USE_GNOME components automatically add the dependencies they need. Please see GNOME Components for an exhaustive list of all USE_GNOME components and which other components they imply and their dependencies.

Here is an example Makefile for a GNOME port that uses many of the techniques outlined in this document. Please use it as a guide for creating new ports.

PORTNAME=	regexxer
DISTVERSION=	0.10
CATEGORIES=	devel textproc gnome
MASTER_SITES=	GNOME

MAINTAINER=	kwm@FreeBSD.org
COMMENT=	Interactive tool for performing search and replace operations
WWW=		http://regexxer.sourceforge.net/

USES=		gettext gmake localbase:ldflags pathfix pkgconfig tar:xz
GNU_CONFIGURE=	yes
USE_GNOME=	gnomeprefix intlhack gtksourceviewmm3

GLIB_SCHEMAS=	org.regexxer.gschema.xml

.include <bsd.port.mk>

The USE_GNOME macro without any arguments does not add any dependencies to the port. USE_GNOME cannot be set after bsd.port.pre.mk.

6.11.3. Variables

This section explains which macros are available and how they are used. Like they are used in the above example. The GNOME Components has a more in-depth explanation. USE_GNOME has to be set for these macros to be of use.

GLIB_SCHEMAS

List of all the glib schema files the port installs. The macro will add the files to the port plist and handle the registration of these files on install and deinstall.

The glib schema files are written in XML and end with the gschema.xml extension. They are installed in the share/glib-2.0/schemas/ directory. These schema files contain all application config values with their default settings. The actual database used by the applications is built by glib-compile-schema, which is run by the GLIB_SCHEMAS macro.

GLIB_SCHEMAS=foo.gschema.xml

Do not add glib schemas to the pkg-plist. If they are listed in pkg-plist, they will not be registered and the applications might not work properly.

GCONF_SCHEMAS

List all the gconf schema files. The macro will add the schema files to the port plist and will handle their registration on install and deinstall.

GConf is the XML-based database that virtually all GNOME applications use for storing their settings. These files are installed into the etc/gconf/schemas directory. This database is defined by installed schema files that are used to generate %gconf.xml key files. For each schema file installed by the port, there must be an entry in the Makefile:

GCONF_SCHEMAS=my_app.schemas my_app2.schemas my_app3.schemas

Gconf schemas are listed in the GCONF_SCHEMAS macro rather than pkg-plist. If they are listed in pkg-plist, they will not be registered and the applications might not work properly.

INSTALLS_OMF

Open Source Metadata Framework (OMF) files are commonly used by GNOME 2 applications. These files contain the application help file information, and require special processing by ScrollKeeper/rarian. To properly register OMF files when installing GNOME applications from packages, make sure that omf files are listed in pkg-plist and that the port Makefile has INSTALLS_OMF defined:

INSTALLS_OMF=yes

When set, bsd.gnome.mk automatically scans pkg-plist and adds appropriate @exec and @unexec directives for each .omf to track in the OMF registration database.

6.12. GNOME Components

For further help with a GNOME port, look at some of the existing ports for examples. The FreeBSD GNOME page has contact information if more help is needed. The components are divided into GNOME components that are currently in use and legacy components. If the component supports argument, they are listed between parenthesis in the description. The first is the default. "Both" is shown if the component defaults to adding to both build and run dependencies.

6.13. Using Qt

For ports that are part of Qt itself, see qt-dist.

6.13.1. Ports That Require Qt

The Ports Collection provides support for Qt 5 and Qt 6 with USES+=qt:5 and USES+=qt:6 respectively. Set USE_QT to the list of required Qt components (libraries, tools, plugins).

The Qt framework exports a number of variables which can be used by ports, some of them listed below:

Table 20. Variables Provided to Ports That Use Qt
`QMAKE`	Full path to `qmake` binary.
`LRELEASE`	Full path to `lrelease` utility.

6.13.2. Component Selection

Individual Qt tool and library dependencies must be specified in USE_QT. Every component can be suffixed with _build or _run, the suffix indicating whether the dependency on the component is at buildtime or runtime. If unsuffixed, the component will be depended on at both build- and runtime. Usually, library components are specified unsuffixed, tool components are mostly specified with the _build suffix and plugin components are specified with the _run suffix. The most commonly used components are listed below (all available components are listed in _USE_QT_ALL, which is generated from _USE_QT_COMMON and _USE_QT[56]_ONLY in /usr/ports/Mk/Uses/qt.mk):

Example 74. Selecting Qt 5 Components

In this example, the ported application uses the Qt 5 graphical user interface library, the Qt 5 core library, all of the Qt 5 code generation tools and Qt 5’s Makefile generator. Since the gui library implies a dependency on the core library, core does not need to be specified. The Qt 5 code generation tools moc, uic and rcc, as well as the Makefile generator qmake are only needed at buildtime, thus they are specified with the _build suffix:

USES=	qt:5
USE_QT=	gui buildtools_build qmake_build

6.13.3. Using `qmake`

If the application provides a qmake project file (*.pro), define USES= qmake along with USE_QT. USES= qmake already implies a build dependency on qmake, therefore the qmake component can be omitted from USE_QT. Similar to CMake, qmake supports out-of-source builds, which can be enabled by specifying the outsource argument (see USES= qmake example). Also see Possible Arguments for USES qmake.

Table 24. Possible Arguments for `USES= qmake`
Variable	Description
`no_configure`	Do not add the configure target. This is implied by `HAS_CONFIGURE=yes` and `GNU_CONFIGURE=yes`. It is required when the build only needs the environment setup from `USES= qmake`, but otherwise runs `qmake` on its own.
`no_env`	Suppress modification of the configure and make environments. It is only required when `qmake` is used to configure the software and the build fails to understand the environment setup by `USES= qmake`.
`norecursive`	Do not pass the `-recursive` argument to `qmake`.
`outsource`	Perform an out-of-source build.

Table 25. Variables for Ports That Use `qmake`
Variable	Description
`QMAKE_ARGS`	Port specific qmake flags to be passed to the `qmake` binary.
`QMAKE_ENV`	Environment variables to be set for the `qmake` binary. The default is `${CONFIGURE_ENV}`.
`QMAKE_SOURCE_PATH`	Path to qmake project files (.pro). The default is `${WRKSRC}` if an out-of-source build is requested, empty otherwise.

When using USES= qmake, these settings are deployed:

CONFIGURE_ARGS+=	--with-qt-includes=${QT_INCDIR} \
			--with-qt-libraries=${QT_LIBDIR} \
			--with-extra-libs=${LOCALBASE}/lib \
			--with-extra-includes=${LOCALBASE}/include

CONFIGURE_ENV+=	QTDIR="${QT_PREFIX}" QMAKE="${QMAKE}" \
		MOC="${MOC}" RCC="${RCC}" UIC="${UIC}" \
		QMAKESPEC="${QMAKESPEC}"

PLIST_SUB+=	QT_INCDIR=${QT_INCDIR_REL} \
		QT_LIBDIR=${QT_LIBDIR_REL} \
		QT_PLUGINDIR=${QT_PLUGINDIR_REL}

Some configure scripts do not support the arguments above. To suppress modification of CONFIGURE_ENV and CONFIGURE_ARGS, set USES= qmake:no_env.

Example 75. USES= qmake Example

This snippet demonstrates the use of qmake for a Qt 5 port:

USES=	qmake:outsource qt:5
USE_QT=	buildtools_build

Qt applications are often written to be cross-platform and often X11/Unix is not the platform they are developed on, which in turn leads to certain loose ends, like:

Missing additional include paths. Many applications come with system tray icon support, but neglect to look for includes and/or libraries in the X11 directories. To add directories to `qmake’s include and library search paths via the command line, use:
```
QMAKE_ARGS+=	INCLUDEPATH+=${LOCALBASE}/include \
		LIBS+=-L${LOCALBASE}/lib
```
Bogus installation paths. Sometimes data such as icons or .desktop files are by default installed into directories which are not scanned by XDG-compatible applications. editors/texmaker is an example for this - look at patch-texmaker.pro in the files directory of that port for a template on how to remedy this directly in the qmake project file.

If the application depends on KDE, set USES+=kde:5 and USE_KDE to the list of required components. _build and _run suffixes can be used to force components dependency type (for example, baseapps_run). If no suffix is set, a default dependency type will be used. To force both types, add the component twice with both suffixes (for example, ecm_build ecm_run). Available components are listed below (up-to-date components are also listed in /usr/ports/Mk/Uses/kde.mk):

Example 76. USE_KDE Example

This is a simple example for a KDE port. USES= cmake instructs the port to utilize CMake, a configuration tool widely used by KDE projects (see Using cmake for detailed usage). USE_KDE brings dependency on KDE libraries. Required KDE components and other dependencies can be determined through the configure log. USE_KDE does not imply USE_QT. If a port requires some Qt components, specify them in USE_QT.

USES=		cmake kde:5 qt:5
USE_KDE=	ecm
USE_QT=		core buildtools_build qmake_build

6.15. Using LXQt

Applications depending on LXQt should set USES+= lxqt and set USE_LXQT to the list of required components from the table below

Table 27. Available LXQt Components
Name	Description
`buildtools`	Helpers for additional CMake modules
`libfmqt`	Libfm Qt bindings
`lxqt`	LXQt core library
`qtxdg`	Qt implementation of freedesktop.org XDG specifications

Example 77. USE_LXQT Example

This is a simple example, USE_LXQT adds a dependency on LXQt libraries. Required LXQt components and other dependencies can be determined from the configure log.

USES=	cmake lxqt qt:5 tar:xz
USE_QT=		core dbus widgets buildtools_build qmake_build
USE_LXQT=	buildtools libfmqt

6.16. Using Java

6.16.1. Variable Definitions

If the port needs a Java™ Development Kit (JDK™) to either build, run or even extract the distfile, then define USE_JAVA.

There are several JDKs in the ports collection, from various vendors, and in several versions. If the port must use a particular version, specify it using the JAVA_VERSION variable. The most current version is java/openjdk18, with java/openjdk17, java/openjdk16, java/openjdk15, java/openjdk14, java/openjdk13, java/openjdk12, java/openjdk11, java/openjdk8, and java/openjdk7 also available.

Table 28. Variables Which May be Set by Ports That Use Java
Variable	Means
`USE_JAVA`	Define for the remaining variables to have any effect.
`JAVA_VERSION`	List of space-separated suitable Java versions for the port. An optional `+` allows specifying a range of versions (allowed values: `8[+] 11[+] 17[+] 18[+] 19[+] 20[+] 21[+]`).
`JAVA_OS`	List of space-separated suitable JDK port operating systems for the port (allowed values: `native linux`).
`JAVA_VENDOR`	List of space-separated suitable JDK port vendors for the port (allowed values: `openjdk oracle`).
`JAVA_BUILD`	When set, add the selected JDK port to the build dependencies.
`JAVA_RUN`	When set, add the selected JDK port to the run dependencies.
`JAVA_EXTRACT`	When set, add the selected JDK port to the extract dependencies.

Below is the list of all settings a port will receive after setting USE_JAVA:

Table 29. Variables Provided to Ports That Use Java
Variable	Value
`JAVA_PORT`	The name of the JDK port (for example, `java/openjdk6`).
`JAVA_PORT_VERSION`	The full version of the JDK port (for example, `1.6.0`). Only the first two digits of this version number are needed, use `${JAVA_PORT_VERSION:C/^([0-9])\.([0-9])(.*)$/\1.\2/}`.
`JAVA_PORT_OS`	The operating system used by the JDK port (for example, `'native'`).
`JAVA_PORT_VENDOR`	The vendor of the JDK port (for example, `'openjdk'`).
`JAVA_PORT_OS_DESCRIPTION`	Description of the operating system used by the JDK port (for example, `'Native'`).
`JAVA_PORT_VENDOR_DESCRIPTION`	Description of the vendor of the JDK port (for example, `'OpenJDK BSD Porting Team'`).
`JAVA_HOME`	Path to the installation directory of the JDK (for example, '/usr/local/openjdk6').
`JAVAC`	Path to the Java compiler to use (for example, '/usr/local/openjdk6/bin/javac').
`JAR`	Path to the `jar` tool to use (for example, '/usr/local/openjdk6/bin/jar' or '/usr/local/bin/fastjar').
`APPLETVIEWER`	Path to the `appletviewer` utility (for example, '/usr/local/openjdk6/bin/appletviewer').
`JAVA`	Path to the `java` executable. Use this for executing Java programs (for example, '/usr/local/openjdk6/bin/java').
`JAVADOC`	Path to the `javadoc` utility program.
`JAVAH`	Path to the `javah` program.
`JAVAP`	Path to the `javap` program.
`JAVA_KEYTOOL`	Path to the `keytool` utility program.
`JAVA_N2A`	Path to the `native2ascii` tool.
`JAVA_POLICYTOOL`	Path to the `policytool` program.
`JAVA_SERIALVER`	Path to the `serialver` utility program.
`RMIC`	Path to the RMI stub/skeleton generator, `rmic`.
`RMIREGISTRY`	Path to the RMI registry program, `rmiregistry`.
`RMID`	Path to the RMI daemon program `rmid`.
`JAVA_CLASSES`	Path to the archive that contains the JDK class files, ${JAVA_HOME}/jre/lib/rt.jar.

Use the java-debug make target to get information for debugging the port. It will display the value of many of the previously listed variables.

Additionally, these constants are defined so all Java ports may be installed in a consistent way:

Table 30. Constants Defined for Ports That Use Java
Constant	Value
`JAVASHAREDIR`	The base directory for everything related to Java. Default: ${PREFIX}/share/java.
`JAVAJARDIR`	The directory where JAR files is installed. Default: ${JAVASHAREDIR}/classes.
`JAVALIBDIR`	The directory where JAR files installed by other ports are located. Default: ${LOCALBASE}/share/java/classes.

The related entries are defined in both PLIST_SUB (documented in Changing pkg-plist Based on Make Variables) and SUB_LIST.

6.16.2. Building with Ant

When the port is to be built using Apache Ant, it has to define USE_ANT. Ant is thus considered to be the sub-make command. When no do-build target is defined by the port, a default one will be set that runs Ant according to MAKE_ENV, MAKE_ARGS and ALL_TARGET. This is similar to the USES= gmake mechanism, which is documented in Building Mechanisms.

6.16.3. Best Practices

When porting a Java library, the port has to install the JAR file(s) in ${JAVAJARDIR}, and everything else under ${JAVASHAREDIR}/${PORTNAME} (except for the documentation, see below). To reduce the packing file size, reference the JAR file(s) directly in the Makefile. Use this statement (where myport.jar is the name of the JAR file installed as part of the port):

PLIST_FILES+=	${JAVAJARDIR}/myport.jar

When porting a Java application, the port usually installs everything under a single directory (including its JAR dependencies). The use of ${JAVASHAREDIR}/${PORTNAME} is strongly encouraged in this regard. It is up the porter to decide whether the port installs the additional JAR dependencies under this directory or uses the already installed ones (from ${JAVAJARDIR}).

When porting a Java™ application that requires an application server such as www/tomcat7 to run the service, it is quite common for a vendor to distribute a .war. A .war is a Web application ARchive and is extracted when called by the application. Avoid adding a .war to pkg-plist. It is not considered best practice. An application server will expand war archive, but not clean it up properly if the port is removed. A more desirable way of working with this file is to extract the archive, then install the files, and lastly add these files to pkg-plist.

TOMCATDIR=	${LOCALBASE}/apache-tomcat-7.0
WEBAPPDIR=	myapplication

post-extract:
	@${MKDIR} ${WRKDIR}/${PORTDIRNAME}
	@${TAR} xf ${WRKDIR}/myapplication.war -C ${WRKDIR}/${PORTDIRNAME}

do-install:
	cd ${WRKDIR} && \
	${INSTALL} -d -o ${WWWOWN} -g ${WWWGRP} ${TOMCATDIR}/webapps/${PORTDIRNAME}
	cd ${WRKDIR}/${PORTDIRNAME} && ${COPYTREE_SHARE} \* ${WEBAPPDIR}/${PORTDIRNAME}

Regardless of the type of port (library or application), the additional documentation is installed in the same location as for any other port. The Javadoc tool is known to produce a different set of files depending on the version of the JDK that is used. For ports that do not enforce the use of a particular JDK, it is therefore a complex task to specify the packing list (pkg-plist). This is one reason why porters are strongly encouraged to use PORTDOCS. Moreover, even if the set of files that will be generated by javadoc can be predicted, the size of the resulting pkg-plist advocates for the use of PORTDOCS.

The default value for DATADIR is ${PREFIX}/share/${PORTNAME}. It is a good idea to override DATADIR to ${JAVASHAREDIR}/${PORTNAME} for Java ports. Indeed, DATADIR is automatically added to PLIST_SUB (documented in Changing pkg-plist Based on Make Variables) so use %%DATADIR%% directly in pkg-plist.

As for the choice of building Java ports from source or directly installing them from a binary distribution, there is no defined policy at the time of writing. However, people from the FreeBSD Java Project encourage porters to have their ports built from source whenever it is a trivial task.

All the features that have been presented in this section are implemented in bsd.java.mk. If the port needs more sophisticated Java support, please first have a look at the bsd.java.mk Git log as it usually takes some time to document the latest features. Then, if the needed support that is lacking would be beneficial to many other Java ports, feel free to discuss it on the freebsd-java.

Although there is a java category for PRs, it refers to the JDK porting effort from the FreeBSD Java project. Therefore, submit the Java port in the ports category as for any other port, unless the issue is related to either a JDK implementation or bsd.java.mk.

Similarly, there is a defined policy regarding the CATEGORIES of a Java port, which is detailed in Categorization.

6.17. Web Applications, Apache and PHP

6.17.1. Apache

Table 31. Variables for Ports That Use Apache
`USE_APACHE`	The port requires Apache. Possible values: `yes` (gets any version), `22`, `24`, `22-24`, `22+`, etc. The default APACHE version is `22`. More details are available in ports/Mk/bsd.apache.mk and at wiki.freebsd.org/Apache/.
`APXS`	Full path to the `apxs` binary. Can be overridden in the port.
`HTTPD`	Full path to the `httpd` binary. Can be overridden in the port.
`APACHE_VERSION`	The version of present Apache installation (read-only variable). This variable is only available after inclusion of bsd.port.pre.mk. Possible values: `22`, `24`.
`APACHEMODDIR`	Directory for Apache modules. This variable is automatically expanded in pkg-plist.
`APACHEINCLUDEDIR`	Directory for Apache headers. This variable is automatically expanded in pkg-plist.
`APACHEETCDIR`	Directory for Apache configuration files. This variable is automatically expanded in pkg-plist.

Table 32. Useful Variables for Porting Apache Modules
`MODULENAME`	Name of the module. Default value is `PORTNAME`. Example: `mod_hello`
`SHORTMODNAME`	Short name of the module. Automatically derived from `MODULENAME`, but can be overridden. Example: `hello`
`AP_FAST_BUILD`	Use `apxs` to compile and install the module.
`AP_GENPLIST`	Also automatically creates a pkg-plist.
`AP_INC`	Adds a directory to a header search path during compilation.
`AP_LIB`	Adds a directory to a library search path during compilation.
`AP_EXTRAS`	Additional flags to pass to `apxs`.

6.17.2. Web Applications

Web applications must be installed into PREFIX/www/appname. This path is available both in Makefile and in pkg-plist as WWWDIR, and the path relative to PREFIX is available in Makefile as WWWDIR_REL.

The user and group of web server process are available as WWWOWN and WWWGRP, in case the ownership of some files needs to be changed. The default values of both are www. Use WWWOWN?= myuser and WWWGRP?= mygroup if the port needs different values. This allows the user to override them easily.

Use WWWOWN and WWWGRP sparingly. Remember that every file the web server can write to is a security risk waiting to happen.

Do not depend on Apache unless the web app explicitly needs Apache. Respect that users may wish to run a web application on a web server other than Apache.

6.17.3. PHP

PHP web applications declare their dependency on it with USES=php. See php for more information.

6.17.4. PEAR Modules

Porting PEAR modules is a very simple process.

Add USES=pear to the port’s Makefile. The framework will install the relevant files in the right places and automatically generate the plist at install time.

Example 78. Example Makefile for PEAR Class

PORTNAME=       Date
DISTVERSION=	1.4.3
CATEGORIES=	devel www pear

MAINTAINER=	someone@example.org
COMMENT=	PEAR Date and Time Zone Classes
WWW=		https://pear.php.net/package/Date/

USES=	pear

.include <bsd.port.mk>

PEAR modules will automatically be flavorized using PHP flavors.

If a non default PEAR_CHANNEL is used, the build and run-time dependencies will automatically be added.

PEAR modules do not need to defined PKGNAMESUFFIX it is automatically filled in using PEAR_PKGNAMEPREFIX. If a port needs to add to PKGNAMEPREFIX, it must also use PEAR_PKGNAMEPREFIX to differentiate between different flavors.

6.17.4.1. Horde Modules

In the same way, porting Horde modules is a simple process.

Add USES=horde to the port’s Makefile. The framework will install the relevant files in the right places and automatically generate the plist at install time.

The USE_HORDE_BUILD and USE_HORDE_RUN variables can be used to add buildtime and runtime dependencies on other Horde modules. See Mk/Uses/horde.mk for a complete list of available modules.

Example 79. Example Makefile for Horde Module

PORTNAME=	Horde_Core
DISTVERSION=	2.14.0
CATEGORIES=	devel www pear

MAINTAINER=	horde@FreeBSD.org
COMMENT=	Horde Core Framework libraries
WWW=		https://pear.horde.org/

OPTIONS_DEFINE=	KOLAB SOCKETS
KOLAB_DESC=	Enable Kolab server support
SOCKETS_DESC=	Depend on sockets PHP extension

USES=	horde
USE_PHP=	session

USE_HORDE_BUILD=	Horde_Role
USE_HORDE_RUN=	Horde_Role Horde_History Horde_Pack \
		Horde_Text_Filter Horde_View

KOLAB_USE=	HORDE_RUN=Horde_Kolab_Server,Horde_Kolab_Session
SOCKETS_USE=	PHP=sockets

.include <bsd.port.mk>

As Horde modules are also PEAR modules they will also automatically be flavorized using PHP flavors.

6.18. Using Python

The Ports Collection supports parallel installation of multiple Python versions. Ports must use a correct python interpreter, according to the user-settable PYTHON_VERSION. Most prominently, this means replacing the path to python executable in scripts with the value of PYTHON_CMD.

Ports that install files under PYTHON_SITELIBDIR must use the pyXY- package name prefix, so their package name embeds the version of Python they are installed into.

PKGNAMEPREFIX=	${PYTHON_PKGNAMEPREFIX}

Table 33. Most Useful Variables for Ports That Use Python
`USES=python`	The port needs Python. The minimal required version can be specified with values such as `3.10+`. Version ranges can also be specified by separating two version numbers with a dash: `USES=python:3.8-3.9`. Note that `USES=python` does not cover Python 2.7, it needs to be requested explicitly with `USES=python:2.7+`.
`USE_PYTHON=distutils`	Use Python distutils for configuring, compiling, and installing. This is required when the port comes with setup.py. This overrides the `do-build` and `do-install` targets and may also override `do-configure` if `GNU_CONFIGURE` is not defined. Additionally, it implies `USE_PYTHON=flavors`.
`USE_PYTHON=autoplist`	Create the packaging list automatically. This also requires `USE_PYTHON=distutils` to be set.
`USE_PYTHON=concurrent`	The port will use an unique prefix, typically `PYTHON_PKGNAMEPREFIX` for certain directories, such as `EXAMPLESDIR` and `DOCSDIR` and also will append a suffix, the python version from `PYTHON_VER`, to binaries and scripts to be installed. This allows ports to be installed for different Python versions at the same time, which otherwise would install conflicting files.
`USE_PYTHON=flavors`	The port does not use distutils but still supports multiple Python versions. `FLAVORS` will be set to the supported Python versions. See `USES`=python and Flavors for more information.
`USE_PYTHON=optsuffix`	If the current Python version is not the default version, the port will gain `PKGNAMESUFFIX=${PYTHON_PKGNAMESUFFIX}`. Only useful with flavors.
`PYTHON_PKGNAMEPREFIX`	Used as a `PKGNAMEPREFIX` to distinguish packages for different Python versions. Example: `py27-`
`PYTHON_SITELIBDIR`	Location of the site-packages tree, that contains installation path of Python (usually `LOCALBASE`). `PYTHON_SITELIBDIR` can be very useful when installing Python modules.
`PYTHONPREFIX_SITELIBDIR`	The PREFIX-clean variant of PYTHON_SITELIBDIR. Always use `%%PYTHON_SITELIBDIR%%` in pkg-plist when possible. The default value of `%%PYTHON_SITELIBDIR%%` is `lib/python%%PYTHON_VERSION%%/site-packages`
`PYTHON_CMD`	Python interpreter command line, including version number.

Table 34. Python Module Dependency Helpers
`PYNUMERIC`	Dependency line for numeric extension.
`PYNUMPY`	Dependency line for the new numeric extension, numpy. (PYNUMERIC is deprecated by upstream vendor).
`PYXML`	Dependency line for XML extension (not needed for Python 2.0 and higher as it is also in base distribution).
`PY_ENUM34`	Conditional dependency on devel/py-enum34 depending on the Python version.
`PY_ENUM_COMPAT`	Conditional dependency on devel/py-enum-compat depending on the Python version.
`PY_PATHLIB`	Conditional dependency on devel/py-pathlib depending on the Python version.
`PY_IPADDRESS`	Conditional dependency on net/py-ipaddress depending on the Python version.
`PY_FUTURES`	Conditional dependency on devel/py-futures depending on the Python version.

A complete list of available variables can be found in /usr/ports/Mk/Uses/python.mk.

All dependencies to Python ports using Python flavors (either with USE_PYTHON=distutils or USE_PYTHON=flavors) must have the Python flavor appended to their origin using @${PY_FLAVOR}. See Makefile for a Simple Python Module.

Example 80. Makefile for a Simple Python Module

PORTNAME=	sample
DISTVERSION=	1.2.3
CATEGORIES=	devel

MAINTAINER=	fred.bloggs@example.com
COMMENT=	Python sample module
WWW=		https://example.com/project/sample/

RUN_DEPENDS=	${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}

USES=		python
USE_PYTHON=	autoplist distutils

.include <bsd.port.mk>

Some Python applications claim to have DESTDIR support (which would be required for staging) but it is broken (Mailman up to 2.1.16, for instance). This can be worked around by recompiling the scripts. This can be done, for example, in the post-build target. Assuming the Python scripts are supposed to reside in PYTHONPREFIX_SITELIBDIR after installation, this solution can be applied:

(cd ${STAGEDIR}${PREFIX} \
  && ${PYTHON_CMD} ${PYTHON_LIBDIR}/compileall.py \
   -d ${PREFIX} -f ${PYTHONPREFIX_SITELIBDIR:S;${PREFIX}/;;})

This recompiles the sources with a path relative to the stage directory, and prepends the value of PREFIX to the file name recorded in the byte-compiled output file by -d. -f is required to force recompilation, and the :S;${PREFIX}/;; strips prefixes from the value of PYTHONPREFIX_SITELIBDIR to make it relative to PREFIX.

6.19. Using Tcl/Tk

The Ports Collection supports parallel installation of multiple Tcl/Tk versions. Ports should try to support at least the default Tcl/Tk version and higher with USES=tcl. It is possible to specify the desired version of tcl by appending :_xx_, for example, USES=tcl:85.

Table 35. The Most Useful Read-Only Variables for Ports That Use Tcl/Tk
`TCL_VER`	chosen major.minor version of Tcl
`TCLSH`	full path of the Tcl interpreter
`TCL_LIBDIR`	path of the Tcl libraries
`TCL_INCLUDEDIR`	path of the Tcl C header files
`TCL_PKG_LIB_PREFIX`	Library prefix, as per TIP595
`TCL_PKG_STUB_POSTFIX`	Stub library postfix
`TK_VER`	chosen major.minor version of Tk
`WISH`	full path of the Tk interpreter
`TK_LIBDIR`	path of the Tk libraries
`TK_INCLUDEDIR`	path of the Tk C header files

See the USES=tcl and USES=tk of Using USES Macros for a full description of those variables. A complete list of those variables is available in /usr/ports/Mk/Uses/tcl.mk.

6.20. Using SDL

USE_SDL is used to autoconfigure the dependencies for ports which use an SDL based library like devel/sdl12 and graphics/sdl_image.

These SDL libraries for version 1.2 are recognized:

These SDL libraries for version 2.0 are recognized:

Therefore, if a port has a dependency on net/sdl_net and audio/sdl_mixer, the syntax will be:

USE_SDL=	net mixer

The dependency devel/sdl12, which is required by net/sdl_net and audio/sdl_mixer, is automatically added as well.

Using USE_SDL with entries for SDL 1.2, it will automatically:

Add a dependency on sdl12-config to BUILD_DEPENDS
Add the variable SDL_CONFIG to CONFIGURE_ENV
Add the dependencies of the selected libraries to LIB_DEPENDS

Using USE_SDL with entries for SDL 2.0, it will automatically:

Add a dependency on sdl2-config to BUILD_DEPENDS
Add the variable SDL2_CONFIG to CONFIGURE_ENV
Add the dependencies of the selected libraries to LIB_DEPENDS

6.21. Using wxWidgets

This section describes the status of the wxWidgets libraries in the ports tree and its integration with the ports system.

6.21.1. Introduction

There are many versions of the wxWidgets libraries which conflict between them (install files under the same name). In the ports tree this problem has been solved by installing each version under a different name using version number suffixes.

The obvious disadvantage of this is that each application has to be modified to find the expected version. Fortunately, most of the applications call the wx-config script to determine the necessary compiler and linker flags. The script is named differently for every available version. Majority of applications respect an environment variable, or accept a configure argument, to specify which wx-config script to call. Otherwise they have to be patched.

6.21.2. Version Selection

To make the port use a specific version of wxWidgets there are two variables available for defining (if only one is defined the other will be set to a default value):

Table 36. Variables to Select wxWidgets Versions
Variable	Description	Default value
`USE_WX`	List of versions the port can use	All available versions
`USE_WX_NOT`	List of versions the port cannot use	None

The available wxWidgets versions and the corresponding ports in the tree are:

Table 37. Available wxWidgets Versions
Version	Port
`2.8`	x11-toolkits/wxgtk28
`3.0`	x11-toolkits/wxgtk30

The variables in Variables to Select wxWidgets Versions can be set to one or more of these combinations separated by spaces:

Table 38. wxWidgets Version Specifications
Description	Example
Single version	`2.8`
Ascending range	`2.8+`
Descending range	`3.0-`
Full range (must be ascending)	`2.8-3.0`

There are also some variables to select the preferred versions from the available ones. They can be set to a list of versions, the first ones will have higher priority.

Table 39. Variables to Select Preferred wxWidgets Versions
Name	Designed for
`WANT_WX_VER`	the port
`WITH_WX_VER`	the user

6.21.3. Component Selection

There are other applications that, while not being wxWidgets libraries, are related to them. These applications can be specified in WX_COMPS. These components are available:

Table 40. Available wxWidgets Components
Name	Description	Version restriction
`wx`	main library	none
`contrib`	contributed libraries	`none`
`python`	wxPython (Python bindings)	`2.8-3.0`

The dependency type can be selected for each component by adding a suffix separated by a semicolon. If not present then a default type will be used (see Default wxWidgets Dependency Types). These types are available:

Table 41. Available wxWidgets Dependency Types
Name	Description
`build`	Component is required for building, equivalent to `BUILD_DEPENDS`
`run`	Component is required for running, equivalent to `RUN_DEPENDS`
`lib`	Component is required for building and running, equivalent to `LIB_DEPENDS`

The default values for the components are detailed in this table:

Table 42. Default wxWidgets Dependency Types
Component	Dependency type
`wx`	`lib`
`contrib`	`lib`
`python`	`run`
`mozilla`	`lib`
`svg`	`lib`

Example 81. Selecting wxWidgets Components

This fragment corresponds to a port which uses wxWidgets version 2.4 and its contributed libraries.

USE_WX=		2.8
WX_COMPS=	wx contrib

6.21.4. Detecting Installed Versions

To detect an installed version, define WANT_WX. If it is not set to a specific version then the components will have a version suffix. HAVE_WX will be filled after detection.

Example 82. Detecting Installed wxWidgets Versions and Components

This fragment can be used in a port that uses wxWidgets if it is installed, or an option is selected.

WANT_WX=	yes

.include <bsd.port.pre.mk>

.if defined(WITH_WX) || !empty(PORT_OPTIONS:MWX) || !empty(HAVE_WX:Mwx-2.8)
USE_WX=			2.8
CONFIGURE_ARGS+=	--enable-wx
.endif

This fragment can be used in a port that enables wxPython support if it is installed or if an option is selected, in addition to wxWidgets, both version 2.8.

USE_WX=		2.8
WX_COMPS=	wx
WANT_WX=	2.8

.include <bsd.port.pre.mk>

.if defined(WITH_WXPYTHON) || !empty(PORT_OPTIONS:MWXPYTHON) || !empty(HAVE_WX:Mpython)
WX_COMPS+=		python
CONFIGURE_ARGS+=	--enable-wxpython
.endif

6.21.5. Defined Variables

These variables are available in the port (after defining one from Variables to Select wxWidgets Versions).

Table 43. Variables Defined for Ports That Use wxWidgets
Name	Description
`WX_CONFIG`	The path to the wxWidgets`wx-config` script (with different name)
`WXRC_CMD`	The path to the wxWidgets`wxrc` program (with different name)
`WX_VERSION`	The wxWidgets version that is going to be used (for example, `2.6`)

6.21.6. Processing in bsd.port.pre.mk

Define WX_PREMK to be able to use the variables right after including bsd.port.pre.mk.

When defining WX_PREMK, then the version, dependencies, components and defined variables will not change if modifying the wxWidgets port variables after including bsd.port.pre.mk.

Example 83. Using wxWidgets Variables in Commands

This fragment illustrates the use of WX_PREMK by running the wx-config script to obtain the full version string, assign it to a variable and pass it to the program.

USE_WX=		2.8
WX_PREMK=	yes

.include <bsd.port.pre.mk>

.if exists(${WX_CONFIG})
VER_STR!=	${WX_CONFIG} --release

PLIST_SUB+=	VERSION="${VER_STR}"
.endif

The wxWidgets variables can be safely used in commands when they are inside targets without the need of WX_PREMK.

6.21.7. Additional `configure` Arguments

Some GNU configure scripts cannot find wxWidgets with just the WX_CONFIG environment variable set, requiring additional arguments. WX_CONF_ARGS can be used for provide them.

Table 44. Legal Values for `WX_CONF_ARGS`
Possible value	Resulting argument
`absolute`	`--with-wx-config=${WX_CONFIG}`
`relative`	`--with-wx=${LOCALBASE} --with-wx-config=${WX_CONFIG:T}`

6.22. Using Lua

This section describes the status of the Lua libraries in the ports tree and its integration with the ports system.

6.22.1. Introduction

There are many versions of the Lua libraries and corresponding interpreters, which conflict between them (install files under the same name). In the ports tree this problem has been solved by installing each version under a different name using version number suffixes.

The obvious disadvantage of this is that each application has to be modified to find the expected version. But it can be solved by adding some additional flags to the compiler and linker.

Applications that use Lua should normally build for just one version. However, loadable modules for Lua are built in a separate flavor for each Lua version that they support, and dependencies on such modules should specify the flavor using the @${LUA_FLAVOR} suffix on the port origin.

6.22.2. Version Selection

A port using Lua should have a line of this form:

USES=	lua

If a specific version of Lua, or range of versions, is needed, it can be specified as a parameter in the form XY (which may be used multiple times), XY+, -XY, or XY-ZA. The default version of Lua as set via DEFAULT_VERSIONS will be used if it falls in the requested range, otherwise the closest requested version to the default will be used. For example:

USES=	lua:52-53

Note that no attempt is made to adjust the version selection based on the presence of any already-installed Lua version.

The XY+ form of version specification should not be used without careful consideration; the Lua API changes to some extent in every version, and configuration tools like CMake or Autoconf will often fail to work on future versions of Lua until updated to do so.

6.22.3. Configuration and Compiler flags

Software that uses Lua may have been written to auto-detect the Lua version in use. In general ports should override this assumption, and force the use of the specific Lua version selected as described above. Depending on the software being ported, this might require any or all of:

Using LUA_VER as part of a parameter to the software’s configuration script via CONFIGURE_ARGS or CONFIGURE_ENV (or equivalent for other build systems);
Adding -I${LUA_INCDIR}, -L${LUA_LIBDIR}, and -llua-${LUA_VER} to CFLAGS, LDFLAGS, LIBS respectively as appropriate;
Patch the software’s configuration or build files to select the correct version.

6.22.4. Version Flavors

A port which installs a Lua module (rather than an application that simply makes use of Lua) should build a separate flavor for each supported Lua version. This is done by adding the module parameter:

USES=	lua:module

A version number or range of versions can be specified as well; use a comma to separate parameters.

Since each flavor must have a different package name, the variable LUA_PKGNAMEPREFIX is provided which will be set to an appropriate value; the intended usage is:

PKGNAMEPREFIX=	${LUA_PKGNAMEPREFIX}

Module ports should normally install files only to LUA_MODLIBDIR, LUA_MODSHAREDIR, LUA_DOCSDIR, and LUA_EXAMPLESDIR, all of which are set up to refer to version-specific subdirectories. Installing any other files must be done with care to avoid conflicts between versions.

A port (other than a Lua module) which wishes to build a separate package for each Lua version should use the flavors parameter:

USES=	lua:flavors

This operates the same way as the module parameter described above, but without the assumption that the package should be documented as a Lua module (so LUA_DOCSDIR and LUA_EXAMPLESDIR are not defined by default). However, the port may choose to define LUA_DOCSUBDIR as a suitable subdirectory name (usually the port’s PORTNAME as long as this does not conflict with the PORTNAME of any module), in which case the framework will define both LUA_DOCSDIR and LUA_EXAMPLESDIR.

As with module ports, a flavored port should avoid installing files that would conflict between versions. Typically this is done by adding LUA_VER_STR as a suffix to program names (e.g. using uniquefiles), and otherwise using either LUA_VER or LUA_VER_STR as part of any other files or subdirectories used outside of LUA_MODLIBDIR and LUA_MODSHAREDIR.

6.22.5. Defined Variables

These variables are available in the port.

Table 45. Variables Defined for Ports That Use Lua
Name	Description
`LUA_VER`	The Lua version that is going to be used (for example, `5.4`)
`LUA_VER_STR`	The Lua version without the dots (for example, `54`)
`LUA_FLAVOR`	The flavor name corresponding to the selected Lua version, to be used for specifying dependencies
`LUA_BASE`	The prefix that should be used to locate Lua (and components) that are already installed
`LUA_PREFIX`	The prefix where Lua (and components) are to be installed by this port
`LUA_INCDIR`	The directory where Lua header files are installed
`LUA_LIBDIR`	The directory where Lua libraries are installed
`LUA_REFMODLIBDIR`	The directory where Lua module libraries (.so) that are already installed are to be found
`LUA_REFMODSHAREDIR`	The directory where Lua modules (.lua) that are already installed are to be found
`LUA_MODLIBDIR`	The directory where Lua module libraries (.so) are to be installed by this port
`LUA_MODSHAREDIR`	The directory where Lua modules (.lua) are to be installed by this port
`LUA_PKGNAMEPREFIX`	The package name prefix used by Lua modules
`LUA_CMD`	The name of the Lua interpreter (e.g. `lua54`)
`LUAC_CMD`	The name of the Lua compiler (e.g. `luac54`)

These additional variables are available for ports that specified the module parameter:

Table 46. Variables Defined for Lua Module Ports
Name	Description
`LUA_DOCSDIR`	the directory to which the module’s documentation should be installed.
`LUA_EXAMPLESDIR`	the directory to which the module’s example files should be installed.

6.23. Using Guile

This section describes the status of Guile in the ports tree and its integration with the ports system.

6.23.1. Introduction

There are multiple versions of the Guile libraries and corresponding interpreters, which conflict between them (install files under the same name). In the ports tree this problem has been solved by installing each version under a different name using version number suffixes. In most cases, applications should detect the correct version from the configuration variables provided and use pkg-config to determine the name and associated paths. However, some applications (especially those using their own configuration rules for cmake or meson) will always try to use the latest available version. In this case, either patch the port or declare a build conflict (see the conflicts option below) to ensure that the correct dependency is generated when building outside of poudriere.

Applications that use Guile should normally build for just one version, preferably the one specified in DEFAULT_VERSIONS, or failing that the latest version that they support. However, Guile or Scheme libraries, or extension modules for Guile are built in a separate flavor for each Guile version that they support, and dependencies on such ports should specify the flavor using the @${GUILE_FLAVOR} suffix on the port origin.

6.23.2. Version Selection

A port using Guile should define USES=guile:arg,arg… with appropriate arguments as follows:

Table 47. Arguments Defined for Ports That Use Guile
Name	Description
`X.Y`	Declare compatibility with Guile version `X.Y`. Currently available versions are `1.8` (obsolete), `2.2` and `3.0`. Multiple versions may be specified.
`flavors`	Create a flavor for every Guile version specified. The version specified by `DEFAULT_VERSIONS` will become the default flavor. Flavor names are of the form `guileXY`.
`build`	Add the Guile interpreter as a build dependency only, rather than a library dependency. `build` and `run` may both be specified.
`run`	Add the Guile interpreter as a runtime dependency only, rather than a library dependency. `build` and `run` may both be specified.
`alias`	Add `BINARY_ALIAS` values for the interpreter and tools.
`conflicts`	Declare `CONFLICTS_BUILD` for Guile versions newer than the one selected. Use this when the port cannot be configured to use a specific Guile version.

Some additional arguments are available for handling unusual cases; see Mk/Uses/guile.mk for details.

Unless build or run is specified, then LIB_DEPENDS receives both the libguile library dependency and also any additional dependencies required by the guile version, e.g. libgc. Normally the port should not need any additional dependencies related to its use of Guile.

6.23.3. Configuration flags

Software that uses Guile should be using the pkg-config mechanism to obtain compiler and linker flags. Some older or esoteric ports may be using guile-config or obtaining values directly from guile instead, which should also work (the alias argument may be useful in some of these cases).

The framework tries to inform the port of the desired Guile version using the following methods:

GUILE_EFFECTIVE_VERSION is added to CONFIGURE_ENV;
The full path to the Guile binary is specified in the GUILE variable in CONFIGURE_ENV and MAKE_ENV;
If the alias option is used, the desired Guile version’s binaries are the ones aliased;
If the alias option is not used, paths to the desired Guile version’s tools (guild, guile-config, etc.) are added to CONFIGURE_ENV and MAKE_ENV as variables GUILD, GUILE_CONFIG, etc.

For some ports, it may be necessary to specify the version in additional ways, such as via CONFIGURE_ARGS or MESON_ARGS, depending on the port.

If none of these methods cause the port to select the specified Guile version when other versions are present, then preferably patch it to do so. If that is not feasible, specify the conflicts option to prevent building the port under conditions where it will detect the wrong version.

6.23.4. Version Flavors

A port which installs a Guile extension or library, or a Scheme library that precompiles for Guile, should build a separate flavor for each supported Guile version. This is done by adding the flavors option.

Since each flavor must have a different package name, such ports must set PKGNAMESUFFIX, typically:

PKGNAMESUFFIX=	-${FLAVOR}

Such ports must install Scheme files to GUILE_SITE_DIR rather than to GUILE_GLOBAL_SITE_DIR even when the files are not version-specific. This often requires patching the port.

Additionally, if such a port installs a .pc file, it must be placed in GUILE_PKGCONFIG_PATH rather than in the global pkgconfig directory. This allows dependent ports to find a correct configuration for the specific Guile version in use.

If a Guile extension port installs a .so file, then it must usually be placed in the Guile-version-specific extensions directory. USE_LDCONFIG should usually not be used.

Any other files installed by a flavored port must likewise be in version-specific directories or use version-specific filenames. For documentation and examples, GUILE_DOCS_DIR and GUILE_EXAMPLES_DIR specify suitable locations in which the port should create a subdirectory, see below.

6.23.5. Defined Variables

These variables are available in the port.

Table 48. Variables Defined for Ports That Use Guile
Name	Sample Value	Description
`GUILE_VER`	`3.0`	Guile version in use.
`GUILE_SFX`	`3`	Short suffix used on some names. Use only with care; may be non-unique or may change in the future.
`GUILE_FLAVOR`	`guile30`	Flavor name corresponding to the selected version.
`GUILE_PORT`	`lang/guile3`	Port origin of the specified Guile version.
`GUILE_PREFIX`	`${PREFIX}`	Directory prefix to be used for installation.
`GUILE_CMD`	`guile-3.0`	Name of the Guile interpreter, with version suffix.
`GUILE_CMDPATH`	`${LOCALBASE}/bin/guile-3.0`	Full path to the Guile interpreter.
`GUILD_CMD`	`guild-3.0`	Name of the Guild tool, with version suffix.
`GUILD_CMDPATH`	`${LOCALBASE}/bin/guild-3.0`	Full path to the Guild tool.
`GUILE__CMD` `GUILE__CMDPATH`		Like `GUILE_CMD` and `GUILE_CMDPATH`, but for other tool binaries.
`GUILE_PKGCONFIG_PATH`	`${LOCALBASE}/libdata/pkgconfig/guile/3.0`	Where packages using `flavors` should install `.pc` files.
`GUILE_INFO_PATH`	`share/info/guile3`	A suitable value for `INFO_PATH` for ports using the `flavors` option.

The following are defined as variables and as PLIST_SUB entries. The variable form is suffixed with _DIR and is a full path (prefixed with GUILE_PREFIX).

Table 49. Path Substitutions Defined for Ports That Use Guile
Name	Sample Value	Description
`GUILE_GLOBAL_SITE`	`share/guile/site`	Site directory shared by all guile versions; this should not usually be used.
`GUILE_SITE`	`share/guile/3.0/site`	Site directory for the selected Guile version.
`GUILE_SITE_CCACHE`	`lib/guile/3.0/site-ccache`	Directory for compiled bytecode files.
`GUILE_DOCS`	`share/doc/guile30`	Parent directory for version-specific documentation.
`GUILE_EXAMPLES`	`share/examples/guile30`	Parent directory for version-specific examples.

6.23.6. Examples

Example 86. Makefile for an application using Guile

This example shows how to reference a Guile library required at build and run time. Notice that the reference must specify a flavor. This example assumes that the application is using pkg-config to locate dependencies.

PORTNAME=	sample
DISTVERSION=	1.2.3
CATEGORIES=	whatever

MAINTAINER=	fred.bloggs@example.com
COMMENT=	Sample
WWW=		https://example.com/guile_sample/sample/

BUILD_DEPENDS=	guile-lib-${GUILE_FLAVOR}>=0.2.5:devel/guile-lib@${GUILE_FLAVOR}
RUN_DEPENDS=	guile-lib-${GUILE_FLAVOR}>=0.2.5:devel/guile-lib@${GUILE_FLAVOR}

USES=		guile:2.2,3.0 pkgconfig

.include <bsd.port.mk>

6.24. Using `iconv`

FreeBSD has a native iconv in the operating system.

For software that needs iconv, define USES=iconv.

When a port defines USES=iconv, these variables will be available:

Variable name Purpose Port iconv (when using WCHAR_T or //TRANSLIT extensions) Base iconv

ICONV_CMD

Directory where the iconv binary resides

${LOCALBASE}/bin/iconv

/usr/bin/iconv

ICONV_LIB

ld argument to link to libiconv (if needed)

-liconv

(empty)

ICONV_PREFIX

Directory where the iconv implementation resides (useful for configure scripts)

${LOCALBASE}

/usr

ICONV_CONFIGURE_ARG

Preconstructed configure argument for configure scripts

--with-libiconv-prefix=${LOCALBASE}

(empty)

ICONV_CONFIGURE_BASE

Preconstructed configure argument for configure scripts

--with-libiconv=${LOCALBASE}

(empty)

These two examples automatically populate the variables with the correct value for systems using converters/libiconv or the native iconv respectively:

Example 87. Simple iconv Usage

USES=		iconv
LDFLAGS+=	-L${LOCALBASE}/lib ${ICONV_LIB}

Example 88. iconv Usage with configure

USES=		iconv
CONFIGURE_ARGS+=${ICONV_CONFIGURE_ARG}

As shown above, ICONV_LIB is empty when a native iconv is present. This can be used to detect the native iconv and respond appropriately.

Sometimes a program has an ld argument or search path hardcoded in a Makefile or configure script. This approach can be used to solve that problem:

Example 89. Fixing Hardcoded -liconv

USES=		iconv

post-patch:
	@${REINPLACE_CMD} -e 's/-liconv/${ICONV_LIB}/' ${WRKSRC}/Makefile

In some cases it is necessary to set alternate values or perform operations depending on whether there is a native iconv. bsd.port.pre.mk must be included before testing the value of ICONV_LIB:

Example 90. Checking for Native iconv Availability

USES=		iconv

.include <bsd.port.pre.mk>

post-patch:
.if empty(ICONV_LIB)
	# native iconv detected
	@${REINPLACE_CMD} -e 's|iconv||' ${WRKSRC}/Config.sh
.endif

.include <bsd.port.post.mk>

6.25. Using Xfce

Ports that need Xfce libraries or applications set USES=xfce.

Specific Xfce library and application dependencies are set with values assigned to USE_XFCE. They are defined in /usr/ports/Mk/Uses/xfce.mk. The possible values are:

Values of USE_XFCE

garcon: sysutils/garcon
libexo: x11/libexo
libgui: x11-toolkits/libxfce4gui
libmenu: x11/libxfce4menu
libutil: x11/libxfce4util
panel: x11-wm/xfce4-panel
thunar: x11-fm/thunar
xfconf: x11/xfce4-conf

Example 91. USES=xfce Example

USES=		xfce
USE_XFCE=	libmenu

Example 92. Using Xfce’s Own GTK2 Widgets

In this example, the ported application uses the GTK2-specific widgets x11/libxfce4menu and x11/xfce4-conf.

USES=		xfce:gtk2
USE_XFCE=	libmenu xfconf

Xfce components included this way will automatically include any dependencies they need. It is no longer necessary to specify the entire list. If the port only needs x11-wm/xfce4-panel, use:

USES=		xfce
USE_XFCE=	panel

There is no need to list the components x11-wm/xfce4-panel needs itself like this:

USES=		xfce
USE_XFCE=	libexo libmenu libutil panel

However, Xfce components and non-Xfce dependencies of the port must be included explicitly. Do not count on an Xfce component to provide a sub-dependency other than itself for the main port.

6.26. Using Budgie

Applications or libraries depending on the Budgie desktop should set USES= budgie and set USE_BUDGIE to the list of required components.

Name Description

libbudgie

Desktop core (library)

libmagpie

Budgie’s X11 window manager and compositor library

raven

All-in-one center in panel for accessing different applications widgets

screensaver

Desktop-specific screensaver

All application widgets communicate through the org.budgie_desktop.Raven service.

The default dependency is lib- and run-time, it can be changed with :build or :run, for example:

USES=		budgie
USE_BUDGIE=	screensaver:build

Example 93. USE_BUDGIE Example

USES=		budgie gettext gnome meson pkgconfig
USE_BUDGIE=	libbudgie

6.27. Using Databases

Use one of the USES macros from Database USES Macros to add a dependency on a database.

Table 50. Database `USES` Macros
Database	USES Macro
Berkeley DB	`bdb`
MariaDB, MySQL, Percona	`mysql`
PostgreSQL	`pgsql`
SQLite	`sqlite`

Example 94. Using Berkeley DB 6

USES=	bdb:6

See bdb for more information.

Example 95. Using MySQL

When a port needs the MySQL client library add

USES=	mysql

See mysql for more information.

Example 96. Using PostgreSQL

When a port needs the PostgreSQL server version 9.6 or later add

USES=		pgsql:9.6+
WANT_PGSQL=	server

See pgsql for more information.

Example 97. Using SQLite 3

USES=	sqlite:3

See sqlite for more information.

6.28. Starting and Stopping Services (`rc` Scripts)

rc.d scripts are used to start services on system startup, and to give administrators a standard way of stopping, starting and restarting the service. Ports integrate into the system rc.d framework. Details on its usage can be found in the rc.d Handbook chapter. Detailed explanation of the available commands is provided in rc(8) and rc.subr(8). Finally, there is an article on practical aspects of rc.d scripting.

With a mythical port called doorman, which needs to start a doormand daemon. Add the following to the Makefile:

USE_RC_SUBR=	doormand

Multiple scripts may be listed and will be installed. Scripts must be placed in the files subdirectory and a .in suffix must be added to their filename. Standard SUB_LIST expansions will be ran against this file. Use of the %%PREFIX%% and %%LOCALBASE%% expansions is strongly encouraged as well. More on SUB_LIST in the relevant section.

As of FreeBSD 6.1-RELEASE, local rc.d scripts (including those installed by ports) are included in the overall rcorder(8) of the base system.

An example simple rc.d script to start the doormand daemon:

#!/bin/sh

# PROVIDE: doormand
# REQUIRE: LOGIN
# KEYWORD: shutdown
#
# Add these lines to /etc/rc.conf.local or /etc/rc.conf
# to enable this service:
#
# doormand_enable (bool):	Set to NO by default.
#				Set it to YES to enable doormand.
# doormand_config (path):	Set to %%PREFIX%%/etc/doormand/doormand.cf
#				by default.

. /etc/rc.subr

name=doormand
rcvar=doormand_enable

load_rc_config $name

: ${doormand_enable:="NO"}
: ${doormand_config="%%PREFIX%%/etc/doormand/doormand.cf"}

command=%%PREFIX%%/sbin/${name}
pidfile=/var/run/${name}.pid

command_args="-p $pidfile -f $doormand_config"

run_rc_command "$1"

Unless there is a very good reason to start the service earlier, or it runs as a particular user (other than root), all ports scripts must use:

REQUIRE: LOGIN

If the startup script launches a daemon that must be shutdown, the following will trigger a stop of the service on system shutdown:

KEYWORD: shutdown

If the script is not starting a persistent service this is not necessary.

For optional configuration elements the "=" style of default variable assignment is preferable to the ":=" style here, since the former sets a default value only if the variable is unset, and the latter sets one if the variable is unset or null. A user might very well include something like:

doormand_flags=""

in their rc.conf.local, and a variable substitution using ":=" would inappropriately override the user’s intention. The _enable variable is not optional, and must use the ":" for the default.

Ports must not start and stop their services when installing and deinstalling. Do not abuse the plist keywords described in the @preexec command,@postexec command,@preunexec command,@postunexec command section by running commands that modify the currently running system, including starting or stopping services.

6.28.1. Pre-Commit Checklist

Before contributing a port with an rc.d script, and more importantly, before committing one, please consult this checklist to be sure that it is ready.

The devel/rclint port can check for most of these, but it is not a substitute for proper review.

If this is a new file, does it have a .sh extension? If so, that must be changed to just file.in since rc.d files may not end with that extension.
Do the name of the file (minus .in), the PROVIDE line, and $ name all match? The file name matching PROVIDE makes debugging easier, especially for rcorder(8) issues. Matching the file name and `$`name makes it easier to figure out which variables are relevant in rc.conf[.local]. It is also a policy for all new scripts, including those in the base system.
Is the REQUIRE line set to LOGIN? This is mandatory for scripts that run as a non-root user. If it runs as root, is there a good reason for it to run prior to LOGIN? If not, it must run after so that local scrips can be loosely grouped to a point in rcorder(8) after most everything in the base is already running.
Does the script start a persistent service? If so, it must have KEYWORD: shutdown.
Make sure there is no KEYWORD: FreeBSD present. This has not been necessary nor desirable for years. It is also an indication that the new script was copy/pasted from an old script, so extra caution must be given to the review.
If the script uses an interpreted language like perl, python, or ruby, make certain that command_interpreter is set appropriately, for example, for Perl, by adding PERL=${PERL} to SUB_LIST and using %%PERL%%. Otherwise,
```
# service name stop
```
will probably not work properly. See service(8) for more information.
Have all occurrences of /usr/local been replaced with %%PREFIX%%?
Do the default variable assignments come after load_rc_config?
Are there default assignments to empty strings? They should be removed, but double-check that the option is documented in the comments at the top of the file.
Are things that are set in variables actually used in the script?
Are options listed in the default name`_flags` things that are actually mandatory? If so, they must be in command_args. -d is a red flag (pardon the pun) here, since it is usually the option to "daemonize" the process, and therefore is actually mandatory.
_name__flags must never be included in command_args (and vice versa, although that error is less common).
Does the script execute any code unconditionally? This is frowned on. Usually these things must be dealt with through a start_precmd.
All boolean tests must use the checkyesno function. No hand-rolled tests for [Yy][Ee][Ss], etc.
If there is a loop (for example, waiting for something to start) does it have a counter to terminate the loop? We do not want the boot to be stuck forever if there is an error.
Does the script create files or directories that need specific permissions, for example, a pid that needs to be owned by the user that runs the process? Rather than the traditional touch(1)/chown(8)/chmod(1) routine, consider using install(1) with the proper command line arguments to do the whole procedure with one step.

6.29. Adding Users and Groups

Some ports require a particular user account to be present, usually for daemons that run as that user. For these ports, choose a unique UID from 50 to 999 and register it in ports/UIDs (for users) and ports/GIDs (for groups). The unique identification should be the same for users and groups.

Please include a patch against these two files when requiring a new user or group to be created for the port.

Then use USERS and GROUPS in Makefile, and the user will be automatically created when installing the port.

USERS=	pulse
GROUPS=	pulse pulse-access pulse-rt

The current list of reserved UIDs and GIDs can be found in ports/UIDs and ports/GIDs.

6.30. Ports That Rely on Kernel Sources

Some ports (such as kernel loadable modules) need the kernel source files so that the port can compile. Here is the correct way to determine if the user has them installed:

USES=	kmod

Apart from this check, the kmod feature takes care of most items that these ports need to take into account.

6.31. Go Libraries

Ports must not package or install Go libs or source code. Go ports must fetch the required deps at the normal fetch time and should only install the programs and things users need, not the things Go developers would need.

Ports should (in order of preference):

Use vendored dependencies included with the package source.
Fetch the versions of deps specified by upstream (in the case of go.mod, vendor.json or similar).
As a last resort (deps are not included nor versions specified exactly) fetch versions of dependencies available at the time of upstream development/release.

6.32. Haskell Libraries

Just like in case of Go language, Ports must not package or install Haskell libraries. Haskell ports must link statically to their dependencies and fetch all distribution files on fetch stage.

6.33. Shell Completion Files

Many modern shells (including bash, fish, tcsh and zsh) support parameter and/or option tab-completion. This support usually comes from completion files, which contain the definitions for how tab completion will work for a certain command. Ports sometimes ship with their own completion files, or porters may have created them themselves.

When available, completion files should always be installed. It is not necessary to make an option for it. If an option is used, though, always enable it in OPTIONS_DEFAULT.

Table 51. Full shell completion file names
`bash`	${PREFIX}/etc/bash_completion.d or ${PREFIX}/share/bash-completion/completions	(any unique file names in one of these folders)
`fish`	${PREFIX}/share/fish/completions/${PORTNAME}.fish
`zsh`	${PREFIX}/share/zsh/site-functions/_${PORTNAME}

Do not register any dependencies on the shells themselves.

Chapter 7. Flavors

7.1. An Introduction to Flavors

Flavors are a way to have multiple variations of a port. The port is built multiple times, with variations.

For example, a port can have a normal version with many features and quite a few dependencies, and a light "lite" version with only basic features and minimal dependencies.

Another example could be, a port can have a GTK flavor and a QT flavor, depending on which toolkit it uses.

7.2. Using FLAVORS

To declare a port having multiple flavors, add FLAVORS to its Makefile. The first flavor in FLAVORS is the default flavor.

It can help simplify the logic of the Makefile to also define FLAVOR as:

FLAVOR?=	${FLAVORS:[1]}

To distinguish flavors from options, which are always uppercase letters, flavor names can only contain lowercase letters, numbers, and the underscore _.

Example 98. Basic Flavors Usage

If a port has a "lite" slave port, the slave port can be removed, and the port can be converted to flavors with:

FLAVORS=	default lite
lite_PKGNAMESUFFIX=	-lite
[...]
.if ${FLAVOR:U} != lite
[enable non lite features]
.endif

Example 99. Another Basic Flavors Usage

If a port has a -nox11 slave port, the slave port can be removed, and the port can be converted to flavors with:

FLAVORS=	x11 nox11
FLAVOR?=	${FLAVORS:[1]}
nox11_PKGNAMESUFFIX=	-nox11
[...]
.if ${FLAVOR} == x11
[enable x11 features]
.endif

Example 100. More Complex Flavors Usage

Here is a slightly edited excerpt of what is present in devel/libpeas, a port that uses the Python flavors. With the default Python 2 and 3 versions being 2.7 and 3.6, it will automatically get FLAVORS=py27 py36

USES=		gnome python
USE_PYTHON=	flavors

.if ${FLAVOR:Upy27:Mpy2*}
USE_GNOME=	pygobject3

CONFIGURE_ARGS+=	--enable-python2 --disable-python3

BUILD_WRKSRC=	${WRKSRC}/loaders/python
INSTALL_WRKSRC=	${WRKSRC}/loaders/python
.else # py3*
USE_GNOME+=	py3gobject3

CONFIGURE_ARGS+=	--disable-python2 --enable-python3 \
			ac_cv_path_PYTHON3_CONFIG=${LOCALBASE}/bin/python${PYTHON_VER}-config

BUILD_WRKSRC=	${WRKSRC}/loaders/python3
INSTALL_WRKSRC=	${WRKSRC}/loaders/python3
.endif

py34_PLIST=	${.CURDIR}/pkg-plist-py3
py35_PLIST=	${.CURDIR}/pkg-plist-py3
py36_PLIST=	${.CURDIR}/pkg-plist-py3

This port does not use USE_PYTHON=distutils but needs Python flavors anyway. To guard against FLAVOR being empty, which would cause a make(1) error, use ${FLAVOR:U} in string comparisons instead of ${FLAVOR}. The Gnome Python gobject3 bindings have two different names, one for Python 2, pygobject3 and one for Python 3, py3gobject3. The configure script has to run in ${WRKSRC}, but we are only interested in building and installing the Python 2 or Python 3 parts of the software, so set the build and install base directories appropriately. Hint about the correct Python 3 config script path name. The packing list is different when the built with Python 3. As there are three possible Python 3 versions, set PLIST for all three using the helper.

7.2.1. Flavors Helpers

To make the Makefile easier to write, a few flavors helpers exist.

This list of helpers will set their variable:

flavor_PKGNAMEPREFIX
flavor_PKGNAMESUFFIX
flavor_PLIST
flavor_DESCR

This list of helpers will append to their variable:

flavor_CONFLICTS
flavor_CONFLICTS_BUILD
flavor_CONFLICTS_INSTALL
flavor_PKG_DEPENDS
flavor_EXTRACT_DEPENDS
flavor_PATCH_DEPENDS
flavor_FETCH_DEPENDS
flavor_BUILD_DEPENDS
flavor_LIB_DEPENDS
flavor_RUN_DEPENDS
flavor_TEST_DEPENDS

Example 101. Flavor Specific PKGNAME

As all packages must have a different package name, flavors must change theirs, using flavor_PKGNAMEPREFIX and flavor_PKGNAMESUFFIX makes this easy:

FLAVORS=	normal lite
lite_PKGNAMESUFFIX=	-lite

7.3. `USES=php` and Flavors

When using php with one of these arguments, phpize, ext, zend, or pecl, the port will automatically have FLAVORS filled in with the PHP versions it supports.

Example 102. Simple USES=php Extension

This will generate package for all the supported versions:

PORTNAME=	some-ext
PORTVERSION=	0.0.1
PKGNAMEPREFIX=	${PHP_PKGNAMEPREFIX}

USES=		php:ext

This will generate package for all the supported versions but 7.2:

PORTNAME=	some-ext
PORTVERSION=	0.0.1
PKGNAMEPREFIX=	${PHP_PKGNAMEPREFIX}

USES=		php:ext
IGNORE_WITH_PHP=	72

7.3.1. PHP Flavors with PHP Applications

PHP applications can also be flavorized.

This allows generating packages for all PHP versions, so that users can use them with whatever version they need on their servers.

PHP applications that are flavorized must append PHP_PKGNAMESUFFIX to their package names.

Example 103. Flavorizing a PHP Application

Adding Flavors support to a PHP application is straightforward:

PKGNAMESUFFIX=	${PHP_PKGNAMESUFFIX}

USES=	php:flavors

When adding a dependency on a PHP flavored port, use @${PHP_FLAVOR}. Never use FLAVOR directly.

7.4. `USES=python` and Flavors

When using python and USE_PYTHON=distutils, the port will automatically have FLAVORS filled in with the Python versions it supports.

Example 104. Simple USES=python

Supposing the current Python supported versions are 2.7, 3.4, 3.5, and 3.6, and the default Python 2 and 3 versions are 2.7 and 3.6, a port with:

USES=	python
USE_PYTHON=	distutils

Will get these flavors: py27, and py36.

USES=	python
USE_PYTHON=	distutils allflavors

Will get these flavors: py27, py34, py35 and py36.

Example 105. USES=python with Version Requirements

Supposing the current Python supported versions are 2.7, 3.4, 3.5, and 3.6, and the default Python 2 and 3 versions are 2.7 and 3.6, a port with:

USES=	python:-3.5
USE_PYTHON=	distutils

Will get this flavor: py27.

USES=	python:-3.5
USE_PYTHON=	distutils allflavors

Will get these flavors: py27, py34, and py35.

USES=	python:3.4+
USE_PYTHON=	distutils

Will get this flavor: py36.

USES=	python:3.4+
USE_PYTHON=	distutils allflavors

Will get these flavors: py34, py35, and py36.

PY_FLAVOR is available to depend on the correct version of Python modules. All dependencies on flavored Python ports should use PY_FLAVOR, and not FLAVOR directly..

Example 106. For a Port Not Using distutils

If the default Python 3 version is 3.6, the following will set PY_FLAVOR to py36:

RUN_DEPENDS=	${PYTHON_PKGNAMEPREFIX}mutagen>0:audio/py-mutagen@${PY_FLAVOR}

USES=	python:3.5+

7.5. `USES=lua` and Flavors

When using lua:module or lua:flavors, the port will automatically have FLAVORS filled in with the Lua versions it supports. However, it is not expected that ordinary applications (rather than Lua modules) should use this feature; most applications that embed or otherwise use Lua should simply use USES=lua.

LUA_FLAVOR is available (and must be used) to depend on the correct version of dependencies regardless of whether the port used the flavors or module parameters.

See Using Lua for further information.

7.6. `USES=guile` and Flavors

When using guile:flavors, the port will automatically have FLAVORS filled in with the Guile versions it supports. However, it is not expected that ordinary applications should use this feature; it is primarily intended for use by libraries and extensions, such as guile-lib or guile-cairo.

GUILE_FLAVOR is available (and must be used) to depend on the correct version of flavored dependencies regardless of whether the port used the flavors parameter or not.

See Using Guile for further information.

Chapter 8. Advanced pkg-plist Practices

8.1. Changing pkg-plist Based on Make Variables

Some ports, particularly the p5- ports, need to change their pkg-plist depending on what options they are configured with (or version of perl, in the case of p5- ports). To make this easy, any instances in pkg-plist of %%OSREL%%, %%PERL_VER%%, and %%PERL_VERSION%% will be substituted appropriately. The value of %%OSREL%% is the numeric revision of the operating system (for example, 4.9). %%PERL_VERSION%% and %%PERL_VER%% is the full version number of perl (for example, 5.8.9). Several other %%VARS%% related to port’s documentation files are described in the relevant section.

To make other substitutions, set PLIST_SUB with a list of VAR=VALUE pairs and instances of %%VAR%% will be substituted with VALUE in pkg-plist.

For instance, if a port installs many files in a version-specific subdirectory, use a placeholder for the version so that pkg-plist does not have to be regenerated every time the port is updated. For example, set:

OCTAVE_VERSION=	${PORTREVISION}
PLIST_SUB=	OCTAVE_VERSION=${OCTAVE_VERSION}

in the Makefile and use %%OCTAVE_VERSION%% wherever the version shows up in pkg-plist. When the port is upgraded, it will not be necessary to edit dozens (or in some cases, hundreds) of lines in pkg-plist.

If files are installed conditionally on the options set in the port, the usual way of handling it is prefixing pkg-plist lines with a %%OPT%% for lines needed when the option is enabled, or %%NO_OPT%% when the option is disabled, and adding OPTIONS_SUB=yes to the Makefile. See OPTIONS_SUB for more information.

For instance, if there are files that are only installed when the X11 option is enabled, and Makefile has:

OPTIONS_DEFINE=	X11
OPTIONS_SUB=	yes

In pkg-plist, put %%X11%% in front of the lines only being installed when the option is enabled, like this :

%%X11%%bin/foo-gui

This substitution will be done between the pre-install and do-install targets, by reading from PLIST and writing to TMPPLIST (default: WRKDIR/.PLIST.mktmp). So if the port builds PLIST on the fly, do so in or before pre-install. Also, if the port needs to edit the resulting file, do so in post-install to a file named TMPPLIST.

Another way of modifying a port’s packing list is based on setting the variables PLIST_FILES and PLIST_DIRS. The value of each variable is regarded as a list of pathnames to write to TMPPLIST along with PLIST contents. While names listed in PLIST_FILES and PLIST_DIRS are subject to %%VAR%% substitution as described above, it is better to use the ${VAR} directly. Except for that, names from PLIST_FILES will appear in the final packing list unchanged, while @dir will be prepended to names from PLIST_DIRS. To take effect, PLIST_FILES and PLIST_DIRS must be set before TMPPLIST is written, that is, in pre-install or earlier.

From time to time, using OPTIONS_SUB is not enough. In those cases, adding a specific TAG to PLIST_SUB inside the Makefile with a special value of @comment, makes package tools to ignore the line. For instance, if some files are only installed when the X11 option is on and the architecture is i386:

.include <bsd.port.pre.mk>

.if ${PORT_OPTIONS:MX11} && ${ARCH} == "i386"
PLIST_SUB+=	X11I386=""
.else
PLIST_SUB+=	X11I386="@comment "
.endif

8.2. Empty Directories

8.2.1. Cleaning Up Empty Directories

When being de-installed, a port has to remove empty directories it created. Most of these directories are removed automatically by pkg(8), but for directories created outside of ${PREFIX}, or empty directories, some more work needs to be done. This is usually accomplished by adding @dir lines for those directories. Subdirectories must be deleted before deleting parent directories.

[...]
@dir /var/games/oneko/saved-games
@dir /var/games/oneko

8.2.2. Creating Empty Directories

Empty directories created during port installation need special attention. They must be present when the package is created. If they are not created by the port code, create them in the Makefile:

post-install:
	${MKDIR} ${STAGEDIR}${PREFIX}/some/directory

Add the directory to pkg-plist like any other. For example:

@dir some/directory

8.3. Configuration Files

If the port installs configuration files to PREFIX/etc (or elsewhere) do not list them in pkg-plist. That will cause pkg delete to remove files that have been carefully edited by the user, and a re-installation will wipe them out.

Instead, install sample files with a filename.sample extension. The @sample macro automates this, see Expanding Package List with Keywords for what it does exactly. For each sample file, add a line to pkg-plist:

@sample etc/orbit.conf.sample

If there is a very good reason not to install a working configuration file by default, only list the sample filename in pkg-plist, without the @sample followed by a space part, and add a message pointing out that the user must copy and edit the file before the software will work.

When a port installs its configuration in a subdirectory of ${PREFIX}/etc, use ETCDIR, which defaults to ${PREFIX}/etc/${PORTNAME}, it can be overridden in the ports Makefile if there is a convention for the port to use some other directory. The %%ETCDIR%% macro will be used in its stead in pkg-plist.

The sample configuration files should always have the .sample suffix. If for some historical reason using the standard suffix is not possible, or if the sample files come from some other directory, use this construct:

@sample etc/orbit.conf-dist etc/orbit.conf

@sample %%EXAMPLESDIR%%/orbit.conf etc/orbit.conf

The format is @sample sample-file actual-config-file.

8.4. Dynamic Versus Static Package List

A static package list is a package list which is available in the Ports Collection either as pkg-plist (with or without variable substitution), or embedded into the Makefile via PLIST_FILES and PLIST_DIRS. Even if the contents are auto-generated by a tool or a target in the Makefile before the inclusion into the Ports Collection by a committer (for example, using make makeplist), this is still considered a static list, since it is possible to examine it without having to download or compile the distfile.

A dynamic package list is a package list which is generated at the time the port is compiled based upon the files and directories which are installed. It is not possible to examine it before the source code of the ported application is downloaded and compiled, or after running a make clean.

While the use of dynamic package lists is not forbidden, maintainers should use static package lists wherever possible, as it enables users to grep(1) through available ports to discover, for example, which port installs a certain file. Dynamic lists should be primarily used for complex ports where the package list changes drastically based upon optional features of the port (and thus maintaining a static package list is infeasible), or ports which change the package list based upon the version of dependent software used. For example, ports which generate docs with Javadoc.

8.5. Automated Package List Creation

First, make sure the port is almost complete, with only pkg-plist missing. Running make makeplist will show an example for pkg-plist. The output of makeplist must be double checked for correctness as it tries to automatically guess a few things, and can get it wrong.

User configuration files should be installed as filename.sample, as it is described in Configuration Files. info/dir must not be listed and appropriate install-info lines must be added as noted in the info files section. Any libraries installed by the port must be listed as specified in the shared libraries section.

8.5.1. Expanding `PLIST_SUB` with Regular Expressions

Strings to be replaced sometimes need to be very specific to avoid undesired replacements. This is a common problem with shorter values.

To address this problem, for each PLACEHOLDER=value, a PLACEHOLDER_regex=regex can be set, with the regex part matching value more precisely.

Example 107. Using PLIST_SUB with Regular Expressions

Perl ports can install architecture dependent files in a specific tree. On FreeBSD to ease porting, this tree is called mach. For example, a port that installs a file whose path contains mach could have that part of the path string replaced with the wrong values. Consider this Makefile:

PORTNAME=	Machine-Build
DISTVERSION=	1
CATEGORIES=	devel perl5
MASTER_SITES=	CPAN
PKGNAMEPREFIX=	p5-

MAINTAINER=	perl@FreeBSD.org
COMMENT=	Building machine
WWW=		https://search.cpan.org/dist/Machine-Build

USES=		perl5
USE_PERL5=	configure

PLIST_SUB=	PERL_ARCH=mach

The files installed by the port are:

/usr/local/bin/machine-build
/usr/local/lib/perl5/site_perl/man/man1/machine-build.1.gz
/usr/local/lib/perl5/site_perl/man/man3/Machine::Build.3.gz
/usr/local/lib/perl5/site_perl/Machine/Build.pm
/usr/local/lib/perl5/site_perl/mach/5.20/Machine/Build/Build.so

Running make makeplist wrongly generates:

bin/%%PERL_ARCH%%ine-build
%%PERL5_MAN1%%/%%PERL_ARCH%%ine-build.1.gz
%%PERL5_MAN3%%/Machine::Build.3.gz
%%SITE_PERL%%/Machine/Build.pm
%%SITE_PERL%%/%%PERL_ARCH%%/%%PERL_VER%%/Machine/Build/Build.so

Change the PLIST_SUB line from the Makefile to:

PLIST_SUB=	PERL_ARCH=mach \
		PERL_ARCH_regex=\bmach\b

Now make makeplist correctly generates:

bin/machine-build
%%PERL5_MAN1%%/machine-build.1.gz
%%PERL5_MAN3%%/Machine::Build.3.gz
%%SITE_PERL%%/Machine/Build.pm
%%SITE_PERL%%/%%PERL_ARCH%%/%%PERL_VER%%/Machine/Build/Build.so

8.6. Expanding Package List with Keywords

All keywords can also take optional arguments in parentheses. The arguments are owner, group, and mode. This argument is used on the file or directory referenced. To change the owner, group, and mode of a configuration file, use:

@sample(games,games,640) etc/config.sample

The arguments are optional. If only the group and mode need to be changed, use:

@sample(,games,660) etc/config.sample

If a keyword is used on an optional entry, it must to be added after the helper:

%%FOO%%@sample etc/orbit.conf.sample

This is because the options plist helpers are used to comment out the line, so they need to be put first. See OPTIONS_SUB for more information.

8.6.1. `@desktop-file-utils`

Will run update-desktop-database -q after installation and deinstallation. Never use directly, add USES=desktop-file-utils to the Makefile.

8.6.2. `@fc` directory

Add a @dir entry for the directory passed as an argument, and run fc-cache -fs on that directory after installation and deinstallation.

8.6.3. `@fontsdir` directory

Add a @dir entry for the directory passed as an argument, and run mkfontscale and mkfontdir on that directory after installation and deinstallation. Additionally, on deinstallation, it removes the fonts.scale and fonts.dir cache files if they are empty.

8.6.4. `@info` file

Add the file passed as argument to the plist, and updates the info document index on installation and deinstallation. Additionally, it removes the index if empty on deinstallation. This should never be used manually, but always through INFO. See Info Files for more information.

8.6.5. `@kld` directory

Runs kldxref on the directory on installation and deinstallation. Additionally, on deinstallation, it will remove the directory if empty.

8.6.6. `@rmtry` file

Will remove the file on deinstallation, and not give an error if the file is not there.

8.6.7. `@sample` file [file]

This is used to handle installation of configuration files, through example files bundled with the package. The "actual", non-sample, file is either the second filename, if present, or the first filename without the .sample extension.

This does three things. First, add the first file passed as argument, the sample file, to the plist. Then, on installation, if the actual file is not found, copy the sample file to the actual file. And finally, on deinstallation, remove the actual file if it has not been modified. See Configuration Files for more information.

8.6.8. `@shared-mime-info` directory

Runs update-mime-database on the directory on installation and deinstallation.

8.6.9. `@shell` file

Add the file passed as argument to the plist.

On installation, add the full path to file to /etc/shells, while making sure it is not added twice. On deinstallation, remove it from /etc/shells.

8.6.10. `@terminfo`

Do not use by itself. If the port installs *.terminfo files, add USES=terminfo to its Makefile.

On installation and deinstallation, if tic is present, refresh ${PREFIX}/shared/misc/terminfo.db from the *.terminfo files in ${PREFIX}/shared/misc.

8.6.11. Base Keywords

There are a few keywords that are hardcoded, and documented in pkg-create(8). For the sake of completeness, they are also documented here.

8.6.11.1. `@` [file]

The empty keyword is a placeholder to use when the file’s owner, group, or mode need to be changed. For example, to set the group of the file to games and add the setgid bit, add:

@(,games,2755) sbin/daemon

8.6.11.2. `@preexec` command, `@postexec` command, `@preunexec` command, `@postunexec` command

Execute command as part of the package installation or deinstallation process.

@preexec command: Execute command as part of the pre-install scripts.
@postexec command: Execute command as part of the post-install scripts.
@preunexec command: Execute command as part of the pre-deinstall scripts.
@postunexec command: Execute command as part of the post-deinstall scripts.

If command contains any of these sequences somewhere in it, they are expanded inline. For these examples, assume that @cwd is set to /usr/local and the last extracted file was bin/emacs.

%F: Expand to the last filename extracted (as specified). In the example case bin/emacs.
%D: Expand to the current directory prefix, as set with @cwd. In the example case /usr/local.
%B: Expand to the basename of the fully qualified filename, that is, the current directory prefix plus the last filespec, minus the trailing filename. In the example case, that would be /usr/local/bin.
%f: Expand to the filename part of the fully qualified name, or the converse of %B. In the example case, emacs.

These keywords are here to help you set up the package so that it is as ready to use as possible. They must not be abused to start services, stop services, or run any other commands that will modify the currently running system.

8.6.11.3. `@mode` mode

Set default permission for all subsequently extracted files to mode. Format is the same as that used by chmod(1). Use without an arg to set back to default permissions (mode of the file while being packed).

This must be a numeric mode, like 644, 4755, or 600. It cannot be a relative mode like u+s.

8.6.11.4. `@owner` user

Set default ownership for all subsequent files to user. Use without an argument to set back to default ownership (root).

8.6.11.5. `@group` group

Set default group ownership for all subsequent files to group. Use without an arg to set back to default group ownership (wheel).

8.6.11.6. `@comment` string

This line is ignored when packing.

8.6.11.7. `@dir` directory

Declare directory name. By default, directories created under PREFIX by a package installation are automatically removed. Use this when an empty directory under PREFIX needs to be created, or when the directory needs to have non default owner, group, or mode. Directories outside of PREFIX need to be registered. For example, /var/db/${PORTNAME} needs to have a @dir entry whereas ${PREFIX}/shared/${PORTNAME} does not if it contains files or uses the default owner, group, and mode.

8.6.11.8. `@exec` command, `@unexec` command (Deprecated)

Execute command as part of the installation or deinstallation process. Please use @preexec command instead.

8.6.11.9. `@dirrm` directory (Deprecated)

Declare directory name to be deleted at deinstall time. By default, directories created under PREFIX by a package installation are deleted when the package is deinstalled.

8.6.11.10. `@dirrmtry` directory (Deprecated)

Declare directory name to be removed, as for @dirrm, but does not issue a warning if the directory cannot be removed.

8.6.12. Creating New Keywords

Package list files can be extended by keywords that are defined in the ${PORTSDIR}/Keywords directory. The settings for each keyword are stored in a UCL file named keyword.ucl. The file must contain at least one of these sections:

attributes
action
pre-install
post-install
pre-deinstall
post-deinstall
pre-upgrade
post-upgrade

8.6.12.1. `attributes`

Changes the owner, group, or mode used by the keyword. Contains an associative array where the possible keys are owner, group, and mode. The values are, respectively, a user name, a group name, and a file mode. For example:

attributes: { owner: "games", group: "games", mode: 0555 }

8.6.12.2. `action`

Defines what happens to the keyword’s parameter. Contains an array where the possible values are:

setprefix: Set the prefix for the next plist entries.
dir: Register a directory to be created on install and removed on deinstall.
dirrm: Register a directory to be deleted on deinstall. Deprecated.
dirrmtry: Register a directory to try and deleted on deinstall. Deprecated.
file: Register a file.
setmode: Set the mode for the next plist entries.
setowner: Set the owner for the next plist entries.
setgroup: Set the group for the next plist entries.
comment: Does not do anything, equivalent to not entering an action section.
ignore_next: Ignore the next entry in the plist.

8.6.12.3. `arguments`

If set to true, adds argument handling, splitting the whole line, %@, into numbered arguments, %1, %2, and so on. For example, for this line:

@foo some.content other.content

%1 and %2 will contain:

some.content
other.content

It also affects how the action entry works. When there is more than one argument, the argument number must be specified. For example:

actions: [file(1)]

8.6.12.4. `pre-install`, `post-install`, `pre-deinstall`, `post-deinstall`, `pre-upgrade`, `post-upgrade`

These keywords contains a sh(1) script to be executed before or after installation, deinstallation, or upgrade of the package. In addition to the usual @exec %foo placeholders described in @preexec command, there is a new one, %@, which represents the argument of the keyword.

8.6.12.5. Custom Keyword Examples

Example 108. Example of a @dirrmtryecho Keyword

This keyword does two things, it adds a @dirrmtry directory line to the packing list, and echoes the fact that the directory is removed when deinstalling the package.

actions: [dirrmtry]
post-deinstall: <<EOD
  echo "Directory %D/%@ removed."
EOD

Example 109. Real Life Example, How @sample is Implemented

This keyword does three things. It adds the first filename passed as an argument to @sample to the packing list, it adds to the post-install script instructions to copy the sample to the actual configuration file if it does not already exist, and it adds to the post-deinstall instructions to remove the configuration file if it has not been modified.

actions: [file(1)]
arguments: true
post-install: <<EOD
  case "%1" in
  /*) sample_file="%1" ;;
  *) sample_file="%D/%1" ;;
  esac
  target_file="${sample_file%.sample}"
  set -- %@
  if [ $# -eq 2 ]; then
      target_file=${2}
  fi
  case "${target_file}" in
  /*) target_file="${target_file}" ;;
  *) target_file="%D/${target_file}" ;;
  esac
  if ! [ -f "${target_file}" ]; then
    /bin/cp -p "${sample_file}" "${target_file}" && \
      /bin/chmod u+w "${target_file}"
  fi
EOD
pre-deinstall: <<EOD
  case "%1" in
  /*) sample_file="%1" ;;
  *) sample_file="%D/%1" ;;
  esac
  target_file="${sample_file%.sample}"
  set -- %@
  if [ $# -eq 2 ]; then
      set -- %@
      target_file=${2}
  fi
  case "${target_file}" in
  /*) target_file="${target_file}" ;;
  *) target_file="%D/${target_file}" ;;
  esac
  if cmp -s "${target_file}" "${sample_file}"; then
    rm -f "${target_file}"
  else
    echo "You may need to manually remove ${target_file} if it is no longer needed."
  fi
EOD

Chapter 9. pkg-*

There are some tricks we have not mentioned yet about the pkg-* files that come in handy sometimes.

9.1. pkg-message

To display a message when the package is installed, place the message in pkg-message. This capability is often useful to display additional installation steps to be taken after a pkg install or pkg upgrade.

pkg-message must contain only information that is vital to setup and operation on FreeBSD, and that is unique to the port in question.
Setup information should only be shown on initial install. Upgrade instructions should be shown only when upgrading from the relevant version.
Do not surround the messages with either whitespace or lines of symbols (like ----------, , or ==========). Leave the formatting to pkg(8).
Committers have blanket approval to constrain existing messages to install or upgrade ranges using the UCL format specifications.
Please be sure to refer to the proper tools for handling services.
- Use service name start to start a service rather than using /usr/local/etc/rc.d/name start
- Use sysrc name_enable=YES to change options in rc.conf

pkg-message supports two formats:

raw: A regular plain text file. Its message is only displayed on install.
UCL: If the file starts with “[” then it is considered to be a UCL file. The UCL format is described on libucl’s GitHub page.

Do not add an entry for pkg-message in pkg-plist.

9.1.1. UCL in pkg-message

The format is the following. It should be an array of objects. The objects themselves can have these keywords:

message: The actual message to be displayed. This keyword is mandatory.
type: When the message should be displayed.
maximum_version: Only if type is upgrade. Display if upgrading from a version strictly lower than the version specified.
minimum_version: Only if type is upgrade. Display if upgrading from a version strictly greater than the version specified.

The maximum_version and minimum_version keywords can be combined.

The type keyword can have three values:

install: The message should only be displayed when the package is installed.
remove: The message should only be displayed when the package is removed.
upgrade: the message should only be displayed during an upgrade of the package..

To preserve the compatibility with non UCL pkg-message files, the first line of a UCL pkg-message MUST be a single “[”, and the last line MUST be a single “]”.

Example 110. UCL Short Strings

The message is delimited by double quotes ", this is used for simple single line strings:

[
{ type: install
  message: "Simple message"
}
]

Example 111. UCL Multiline Strings

Multiline strings use the standard here document notation. The multiline delimiter must start just after << symbols without any whitespace and it must consist of capital letters only. To finish a multiline string, add the delimiter string on a line of its own without any whitespace. The message from UCL Short Strings can be written as:

[
{ type: install
  message: <<EOM
Simple message
EOM
}
]

Example 112. Display a Message on Install/Deinstall

When a message only needs to be displayed on installation or uninstallation, set the type:

[
{
  type: remove
  message: "package being removed."
}
{ type: install, message: "package being installed."}
]

Example 113. Display a Message on Upgrade

When a port is upgraded, the message displayed can be even more tailored to the port’s needs.

[
{
  type: upgrade
  message: "Package is being upgraded."
}
{
  type: upgrade
  maximum_version: "1.0"
  message: "Upgrading from before 1.0 need to do this."
}
{
  type: upgrade
  minimum_version: "1.0"
  message: "Upgrading from after 1.0 should do that."
}
{
  type: upgrade
  maximum_version: "3.0"
  minimum_version: "1.0"
  message: "Upgrading from > 1.0 and < 3.0 remove that file."
}
]

When displaying a message on upgrade, it is important to limit when it is being shown to the user. Most of the time it is by using maximum_version to limit its usage to upgrades from before a certain version when something specific needs to be done.

9.2. pkg-install, pkg-pre-install, and pkg-post-install

If the port needs to execute commands when the binary package is installed with pkg add or pkg install, use pkg-install. It is run twice by pkg, the first time as ${SH} pkg-install ${PKGNAME} PRE-INSTALL before the package is installed, and the second time as ${SH} pkg-install ${PKGNAME} POST-INSTALL after it has been installed. $2 can be tested to determine which mode the script is being run in. The PKG_PREFIX environment variable is set to the package installation directory.

If using pkg-pre-install or pkg-post-install instead, the script is run only once (before or after installing the package), with the single argument ${PKGNAME}. Using pkg-pre-install.lua or pkg-post-install.lua will run a lua script instead of a shell script. Lua scripts run by pkg provide some extensions and a few restrictions, both explained in pkg-lua-script(5).

Using pkg-pre-install (or pkg-pre-install.lua) and pkg-post-install (or pkg-post-install.lua) is preferred to using pkg-install.

These scripts are automatically added to the packing list.

These scripts are here to simplify package configuration after installation. They must not be abused to start services, stop services, or run any other commands that will modify the currently running system.

9.3. pkg-deinstall, pkg-pre-deinstall, and pkg-post-deinstall

These scripts execute when a package is removed.

The pkg-deinstall script is run twice by pkg delete. The first time as ${SH} pkg-deinstall ${PKGNAME} DEINSTALL before the port is de-installed and the second time as ${SH} pkg-deinstall ${PKGNAME} POST-DEINSTALL after the port has been de-installed. $2 can be tested to determine which mode the script is being run in. The PKG_PREFIX environment variable is set to the package installation directory.

If using pkg-pre-deinstall or pkg-post-deinstall instead, the script is run only once (before or after deinstalling the package), with the single argument ${PKGNAME}. Using pkg-pre-deinstall.lua or pkg-post-deinstall.lua will run a lua script instead of a shell script. Lua scripts run by pkg provide some extensions and a few restrictions, both explained in pkg-lua-script(5).

Using pkg-pre-deinstall (or pkg-pre-deinstall.lua) and pkg-post-deinstall (or pkg-post-deinstall.lua) is preferred to using pkg-deinstall.

These scripts are automatically added to the packing list.

These scripts are here to simplify cleanup after package deinstallation. They must not be abused to start services, stop services, or run any other commands that will modify the currently running system.

9.4. Changing the Names of pkg-*

All the names of pkg-* are defined using variables that can be changed in the Makefile if needed. This is especially useful when sharing the same pkg-* files among several ports or when it is necessary to write to one of these files. See writing to places other than WRKDIR for why it is a bad idea to write directly into the directory containing the pkg-* files.

Here is a list of variable names and their default values. (PKGDIR defaults to ${MASTERDIR}.)

Variable Default value

DESCR

${PKGDIR}/pkg-descr

PLIST

${PKGDIR}/pkg-plist

PKGINSTALL

${PKGDIR}/pkg-install

PKGPREINSTALL

${PKGDIR}/pkg-pre-install

PKGPOSTINSTALL

${PKGDIR}/pkg-post-install

PKGDEINSTALL

${PKGDIR}/pkg-deinstall

PKGPREDEINSTALL

${PKGDIR}/pkg-pre-deinstall

PKGPOSTDEINSTALL

${PKGDIR}/pkg-post-deinstall

PKGMESSAGE

${PKGDIR}/pkg-message

9.5. Making Use of `SUB_FILES` and `SUB_LIST`

SUB_FILES and SUB_LIST are useful for dynamic values in port files, such as the installation PREFIX in pkg-message.

SUB_FILES specifies a list of files to be automatically modified. Each file in the SUB_FILES list must have a corresponding file.in present in FILESDIR. A modified version will be created as ${WRKDIR}/file. Files defined as a value of USE_RC_SUBR are automatically added to SUB_FILES. For the files pkg-message, pkg-install, and pkg-deinstall, the corresponding Makefile variable is automatically set to point to the processed version.

SUB_LIST is a list of VAR=VALUE pairs. For each pair, %%VAR%% will be replaced with VALUE in each file listed in SUB_FILES. Several common pairs are automatically defined: PREFIX, LOCALBASE, DATADIR, DOCSDIR, EXAMPLESDIR, WWWDIR, and ETCDIR. Any line beginning with @comment followed by a space, will be deleted from resulting files after a variable substitution.

This example replaces %%ARCH%% with the system architecture in a pkg-message:

SUB_FILES=	pkg-message
SUB_LIST=	ARCH=${ARCH}

Note that for this example, pkg-message.in must exist in FILESDIR.

Example of a good pkg-message.in:

Now it is time to configure this package.
Copy %%PREFIX%%/shared/examples/putsy/%%ARCH%%.conf into your home directory
as .putsy.conf and edit it.

Chapter 10. Testing the Port

10.1. Running `make describe`

Several of the FreeBSD port maintenance tools, such as portupgrade(1), rely on a database called /usr/ports/INDEX which keeps track of such items as port dependencies. INDEX is created by the top-level ports/Makefile via make index, which descends into each port subdirectory and executes make describe there. Thus, if make describe fails in any port, no one can generate INDEX, and many people will quickly become unhappy.

It is important to be able to generate this file no matter what options are present in make.conf, so please avoid doing things such as using .error statements when (for instance) a dependency is not satisfied. (See Avoid Use of the .error Construct.)

If make describe produces a string rather than an error message, everything is probably safe. See bsd.port.mk for the meaning of the string produced.

Also note that running a recent version of portlint (as specified in the next section) will cause make describe to be run automatically.

10.2. Running `make test`

Even if the port builds fine, it is a good idea to ensure that the software correctly does what it is supposed to do. If the original upstream project provides tests along with the software, it is a good idea to run them and check everything works as expected.

A port can enable tests automatically by using the TEST_TARGET variable. When set, this variable contains the name of the testing target of the port. This is usually just test but other names include tests, check or for specific cases things like run_tests.py.

In addition to the TEST_TARGET variable the framework provides the following variables to control the tests execution:

TEST_WRKSRC is the directory to do the tests in.
TEST_ENV contains additional variables to be passed to the test stage.
TEST_ARGS contains any extra arguments passed to the test stage.

Examples of use of these variables can be found in cad/xyce, www/libjwt and others.

Please make sure that tests do not break when updating a port.

10.3. Portclippy / Portfmt

Those tools come from ports-mgmt/portfmt.

Portclippy is a linter that checks if variables in the Makefile are in the correct order according to Order of Variables in Port Makefiles.

Portfmt is a tool for automatically formatting Makefile.

10.4. Portlint

Do check the port with portlint before submitting or committing it. portlint warns about many common errors, both functional and stylistic. For a new port, portlint -A is the most thorough; for an existing port, portlint -C is sufficient.

Since portlint uses heuristics to try to figure out errors, it can produce false positive warnings. In addition, occasionally something that is flagged as a problem really cannot be done in any other way due to limitations in the ports framework. When in doubt, the best thing to do is ask on FreeBSD ports mailing list.

10.5. Port Tools

The ports-mgmt/porttools program is part of the Ports Collection.

port is the front-end script, which can help simplify the testing job. Whenever a new port or an update to an existing one needs testing, use port test to test the port, including the portlint checking. This command also detects and lists any files that are not listed in pkg-plist. For example:

# port test /usr/ports/net/csup

10.6. `PREFIX` and `DESTDIR`

PREFIX determines where the port will be installed. It defaults to /usr/local, but can be set by the user to a custom path like /opt. The port must respect the value of this variable.

DESTDIR, if set by the user, determines the complete alternative environment, usually a jail or an installed system mounted somewhere other than /. A port will actually install into DESTDIR/PREFIX, and register with the package database in DESTDIR/var/db/pkg. DESTDIR is handled automatically by the ports infrastructure with chroot(8). There is no need for modifications or any extra care to write DESTDIR-compliant ports.

The value of PREFIX will be set to LOCALBASE (defaulting to /usr/local). If USE_LINUX_PREFIX is set, PREFIX will be LINUXBASE (defaulting to /compat/linux).

Avoiding hard-coded /usr/local paths in the source makes the port much more flexible and able to cater to the needs of other sites. Often, this can be accomplished by replacing occurrences of /usr/local in the port’s various Makefiles with ${PREFIX}. This variable is automatically passed down to every stage of the build and install processes.

Make sure the application is not installing things in /usr/local instead of PREFIX. A quick test for such hard-coded paths is:

% make clean; make package PREFIX=/var/tmp/`make -V PORTNAME`

If anything is installed outside of PREFIX, the package creation process will complain that it cannot find the files.

In addition, it is worth checking the same with the stage directory support (see Staging):

% make stage && make check-plist && make stage-qa && make package

check-plist checks for files missing from the plist, and files in the plist that are not installed by the port.
stage-qa checks for common problems like bad shebang, symlinks pointing outside the stage directory, setuid files, and non-stripped libraries…

These tests will not find hard-coded paths inside the port’s files, nor will it verify that LOCALBASE is being used to correctly refer to files from other ports. The temporarily installed port in /var/tmp/make -V PORTNAME must be tested for proper operation to make sure there are no problems with paths.

PREFIX must not be set explicitly in a port’s Makefile. Users installing the port may have set PREFIX to a custom location, and the port must respect that setting.

Refer to programs and files from other ports with the variables mentioned above, not explicit pathnames. For instance, if the port requires a macro PAGER to have the full pathname of less, do not use a literal path of /usr/local/bin/less. Instead, use ${LOCALBASE}:

-DPAGER=\"${LOCALBASE}/bin/less\"

The path with LOCALBASE is more likely to still work if the system administrator has moved the whole /usr/local tree somewhere else.

All these tests are done automatically when running poudriere testport or poudriere bulk -t. It is highly recommended that every ports contributor install and test their ports with it. See poudriere for more information.

10.7. poudriere

For a ports contributor, poudriere is one of the most important and helpful testing and build tools. Its main features include:

Bulk building of the entire ports tree, specific subsets of the ports tree, or a single port including its dependencies
Automatic packaging of build results
Generation of build log files per port
Providing a signed pkg(8) repository
Testing of port builds before submitting a patch to the FreeBSD bug tracker or committing to the ports tree
Testing for successful ports builds using different options

Because poudriere performs its building in a clean jail(8) environment and uses zfs(8) features, it has several advantages over traditional testing on the host system:

No pollution of the host environment: No leftover files, no accidental removals, no changes of existing configuration files.
Verify pkg-plist for missing or superfluous entries
Ports committers sometimes ask for a poudriere log alongside a patch submission to assess whether the patch is ready for integration into the ports tree

It is also quite straightforward to set up and use, has no dependencies, and will run on any supported FreeBSD release. This section shows how to install, configure, and run poudriere as part of the normal workflow of a ports contributor.

The examples in this section show a default file layout, as standard in FreeBSD. Substitute any local changes accordingly. The ports tree, represented by ${PORTSDIR}, is located in /usr/ports. Both ${LOCALBASE} and ${PREFIX} are /usr/local by default.

10.7.1. Installing poudriere

poudriere is available in the ports tree in ports-mgmt/poudriere. It can be installed using pkg(8) or from ports:

# pkg install poudriere

# make -C /usr/ports/ports-mgmt/poudriere install clean

There is also a work-in-progress version of poudriere which will eventually become the next release. It is available in ports-mgmt/poudriere-devel. This development version is used for the official FreeBSD package builds, so it is well tested. It often has newer interesting features. A ports committer will want to use the development version because it is what is used in production, and has all the new features that will make sure everything is exactly right. A contributor will not necessarily need those as the most important fixes are backported to released version. The main reason for the use of the development version to build the official package is because it is faster, in a way that will shorten a full build from 18 hours to 17 hours when using a high end 32 CPU server with 128GB of RAM. Those optimizations will not matter a lot when building ports on a desktop machine.

10.7.2. Setting Up poudriere

The port installs a default configuration file, /usr/local/etc/poudriere.conf. Each parameter is documented in the configuration file.

Here is a minimal example config file:

ZPOOL=zroot
BASEFS=/usr/local/poudriere
DISTFILES_CACHE=/usr/ports/distfiles
RESOLV_CONF=/etc/resolv.conf

ZPOOL: The name of the ZFS storage pool which poudriere shall use. Must be listed in the output of zpool status.
BASEFS: The root mount point for poudriere file systems. This entry will cause poudriere to mount tank/poudriere to /poudriere.
DISTFILES_CACHE: Defines where distfiles are stored. In this example, poudriere and the host share the distfiles storage directory. This avoids downloading tarballs which are already present on the system. Please create this directory if it does not already exist so that poudriere can find it.
RESOLV_CONF: Use the host /etc/resolv.conf inside jails for DNS. This is needed so jails can resolve the URLs of distfiles when downloading. It is not needed when using a proxy. Refer to the default configuration file for proxy configuration.

10.7.3. Creating poudriere Jails

Create the base jails which poudriere will use for building:

# poudriere jail -c -j 131Ramd64 -v 13.1-RELEASE -a amd64

Fetch a 13.1-RELEASE for amd64 from the FTP server given by FREEBSD_HOST in poudriere.conf, create the zfs file system tank/poudriere/jails/131Ramd64, mount it on /poudriere/jails/131Ramd64 and extract the 13.1-RELEASE tarballs into this file system.

# poudriere jail -c -j 12i386 -v stable/12 -a i386 -m git+https

Create tank/poudriere/jails/12i386, mount it on /poudriere/jails/12i386, then check out the tip of the Git branch of FreeBSD-12-STABLE from GIT_HOST in poudriere.conf or the default git.freebsd.org into /poudriere/jails/12i386/usr/src, then complete a buildworld and install it into /poudriere/jails/12i386.

While it is possible to build a newer version of FreeBSD on an older version, most of the time it will not run. For example, if a stable/13 jail is needed, the host will have to run stable/13 too. Running 13.1-RELEASE is not enough.

To create a poudriere jail for 14.0-CURRENT:

# poudriere jail -c -j 14amd64 -v main -a amd64 -m git+https

In order to run a 14.0-CURRENT poudriere jail the host must be running 14.0-CURRENT. In general, newer kernels can build and run older jails. For instance, a 14.0-CURRENT kernel can build and run a 12.4-STABLE if the COMPAT_FREEBSD12 kernel option was compiled in (on by default in 14.0-CURRENTGENERIC kernel config).

A list of jails currently known to poudriere can be shown with poudriere jail -l:

# poudriere jail -l
JAILNAME             VERSION              ARCH    METHOD
131Ramd64            13.1-RELEASE         amd64   ftp
12i386               12.4-STABLE          i386    git+https

10.7.4. Keeping poudriere Jails Updated

Managing updates is very straightforward. The command:

# poudriere jail -u -j JAILNAME

updates the specified jail to the latest version available. For FreeBSD releases, update to the latest patchlevel with freebsd-update(8). For FreeBSD versions built from source, update to the latest git revision in the branch.

For jails employing a git+* method, it is helpful to add -J NumberOfParallelBuildJobs to speed up the build by increasing the number of parallel compile jobs used. For example, if the building machine has 6 CPUs, use:

# poudriere jail -u -J 6 -j JAILNAME

10.7.5. Setting Up Ports Trees for Use with poudriere

There are multiple ways to use ports trees in poudriere. The most straightforward way is to have poudriere create a default ports tree for itself, using Git:

# poudriere ports -c -m git+https -B main

These commands create tank/poudriere/ports/default, mount it on /poudriere/ports/default, and populate it using Git. Afterward it is included in the list of known ports trees:

# poudriere ports -l
PORTSTREE METHOD    TIMESTAMP           PATH
default   git+https 2020-07-20 04:23:56 /poudriere/ports/default

Note that the "default" ports tree is special. Each of the build commands explained later will implicitly use this ports tree unless specifically specified otherwise. To use another tree, add -p treename to the commands.

The best way to deal with local modifications for a ports contributor is to use Git. As with the creation of jails, it is possible to use a different method for creating the ports tree. To add an additional ports tree for testing local modifications and ports development, checking out the tree via git (as described above) is preferable.

10.7.6. Using Manually Managed Ports Trees with poudriere

Depending on the workflow, it can be extremely helpful to use ports trees which are maintained manually. For instance, if there is a local copy of the ports tree in /work/ports, point poudriere to the location:

# poudriere ports -c -m null -M /work/ports -p development

This will be listed in the table of known trees:

# poudriere ports -l
PORTSTREE   METHOD    TIMESTAMP           PATH
development null      2020-07-20 05:06:33 /work/ports

The dash or null in the METHOD column means that poudriere will not update or change this ports tree, ever. It is completely up to the user to maintain this tree, including all local modifications that may be used for testing new ports and submitting patches.

10.7.7. Keeping poudriere Ports Trees Updated

As straightforward as with jails described earlier:

# poudriere ports -u -p PORTSTREE

Will update the given PORTSTREE, one tree given by the output of poudriere -l, to the latest revision available on the official servers.

Ports trees without a method, see Using Manually Managed Ports Trees with poudriere, cannot be updated like this and must be updated manually by the porter.

10.7.8. Testing Ports

After jails and ports trees have been set up, the result of a contributor’s modifications to the ports tree can be tested.

For example, local modifications to the www/firefox port located in /work/ports/www/firefox can be tested in the previously created 13.1-RELEASE jail:

# poudriere testport -j 131Ramd64 -p development -o www/firefox

This will build all dependencies of Firefox. If a dependency has been built previously and is still up-to-date, the pre-built package is installed. If a dependency has no up-to-date package, one will be built with default options in a jail. Then Firefox itself is built.

The complete build of every port is logged to /poudriere/data/logs/bulk/131Ri386-development/build-time/logs.

The directory name 131Ri386-development is derived from the arguments to -j and -p, respectively. For convenience, a symbolic link /poudriere/data/logs/bulk/131Ri386-development/latest is also maintained. The link points to the latest build-time directory. Also in this directory is an index.html for observing the build process with a web browser.

By default, poudriere cleans up the jails and leaves log files in the directories mentioned above. To ease investigation, jails can be kept running after the build by adding -i to testport:

# poudriere testport -j 131Ramd64 -p development -i -o www/firefox

After the build completes, and regardless of whether it was successful, a shell is provided within the jail. The shell is used to investigate further. poudriere can be told to leave the jail running after the build finishes with -I. poudriere will show the command to run when the jail is no longer needed. It is then possible to jexec(8) into it:

# poudriere testport -j 131Ramd64 -p development -I -o www/firefox
[...]
====>> Installing local Pkg repository to /usr/local/etc/pkg/repos
====>> Leaving jail 131Ramd64-development-n running, mounted at /poudriere/data/.m/131Ramd64-development/ref for interactive run testing
====>> To enter jail: jexec 131Ramd64-development-n env -i TERM=$TERM /usr/bin/login -fp root
====>> To stop jail: poudriere jail -k -j 131Ramd64 -p development
# jexec 131Ramd64-development-n env -i TERM=$TERM /usr/bin/login -fp root
# [do some stuff in the jail]
# exit
# poudriere jail -k -j 131Ramd64 -p development
====>> Umounting file systems

An integral part of the FreeBSD ports build infrastructure is the ability to tweak ports to personal preferences with options. These can be tested with poudriere as well. Adding the -c:

# poudriere testport -c -o www/firefox

Presents the port configuration dialog before the port is built. The ports given after -o in the format category/portname will use the specified options, all dependencies will use the default options. Testing dependent ports with non-default options can be accomplished using sets, see Using Sets.

When testing ports where pkg-plist is altered during build depending on the selected options, it is recommended to perform a test run with all options selected and one with all options deselected.

10.7.9. Using Sets

For all actions involving builds, a so-called set can be specified using -z setname. A set refers to a fully independent build. This allows, for instance, usage of testport with non-standard options for the dependent ports.

To use sets, poudriere expects an existing directory structure similar to PORT_DBDIR, defaults to /var/db/ports in its configuration directory. This directory is then nullfs(5)-mounted into the jails where the ports and their dependencies are built. Usually a suitable starting point can be obtained by recursively copying the existing PORT_DBDIR to /usr/local/etc/poudriere.d/jailname-portname-setname-options. This is described in detail in poudriere(8). For instance, testing www/firefox in a specific set named devset, add the -z devset parameter to the testport command:

# poudriere testport -j 131Ramd64 -p development -z devset -o www/firefox

This will look for the existence of these directories in this order:

/usr/local/etc/poudriere.d/131Ramd64-development-devset-options
/usr/local/etc/poudriere.d/131Ramd64-devset-options
/usr/local/etc/poudriere.d/131Ramd64-development-options
/usr/local/etc/poudriere.d/devset-options
/usr/local/etc/poudriere.d/development-options
/usr/local/etc/poudriere.d/131Ramd64-options
/usr/local/etc/poudriere.d/options

From this list, poudriere nullfs(5)-mounts the first existing directory tree into the /var/db/ports directory of the build jails. Hence, all custom options are used for all the ports during this run of testport.

After the directory structure for a set is provided, the options for a particular port can be altered. For example:

# poudriere options -c www/firefox -z devset

The configuration dialog for www/firefox is shown, and options can be edited. The selected options are saved to the devset set.

poudriere is very flexible in the option configuration. poudriere can be set for particular jails, ports trees, and for multiple ports by one command. Refer to poudriere(8) for details.

10.7.10. Providing a Custom make.conf File

Similar to using sets, poudriere will also use a custom make.conf if it is provided. No special command line argument is necessary. Instead, poudriere looks for existing files matching a name scheme derived from the command line. For instance:

# poudriere testport -j 131Ramd64 -p development -z devset -o www/firefox

causes poudriere to check for the existence of these files in this order:

/usr/local/etc/poudriere.d/make.conf
/usr/local/etc/poudriere.d/devset-make.conf
/usr/local/etc/poudriere.d/development-make.conf
/usr/local/etc/poudriere.d/131Ramd64-make.conf
/usr/local/etc/poudriere.d/131Ramd64-development-make.conf
/usr/local/etc/poudriere.d/131Ramd64-devset-make.conf
/usr/local/etc/poudriere.d/131Ramd64-development-devset-make.conf

Unlike with sets, all of the found files will be appended, in that order, into one make.conf inside the build jails. It is hence possible to have general make variables, intended to affect all builds in /usr/local/etc/poudriere.d/make.conf. Special variables, intended to affect only certain jails or sets can be set in specialised make.conf files, such as /usr/local/etc/poudriere.d/131Ramd64-development-devset-make.conf.

Example 114. Using make.conf to Change Default Perl

To build a set with a non default Perl version, for example, 5.20, using a set named perl5-20, create a perl5-20-make.conf with this line:

DEFAULT_VERSIONS+= perl=5.20

Note the use of += so that if the variable is already set in the default make.conf its content will not be overwritten.

10.7.11. Pruning no Longer Needed Distfiles

poudriere comes with a built-in mechanism to remove outdated distfiles that are no longer used by any port of a given tree. The command

# poudriere distclean -p portstree

will scan the distfiles folder, DISTFILES_CACHE in poudriere.conf, versus the ports tree given by the -p portstree argument and prompt for removal of those distfiles. To skip the prompt and remove all unused files unconditionally, the -y argument can be added:

# poudriere distclean -p portstree -y

10.8. Debugging ports

Sometimes things go wrong and the port fails at run time. The framework provides some facilities to help in debugging ports. These helpers are limited since the way of debugging a port heavily depends on the technology used. The following variables help with debugging ports:

WITH_DEBUG. If set, ports are built with debugging symbols.
WITH_DEBUG_PORTS. Specifies a list of ports to be built with WITH_DEBUG set.
DEBUG_FLAGS. Used to specify additional flags to CFLAGS. Defaults to -g.

When WITH_DEBUG is set, either globally or for a list of ports, the resulting binaries are not stripped.

These variables can be specified in make.conf or in the command line:

# cd category/port && make -DWITH_DEBUG DEBUG_FLAGSS="-g -O0"

If the port is built using ports-mgmt/poudriere the debugging variables must be specified in poudriere’s make.conf and not in /etc/make.conf. Refer to ports-mgmt/poudriere documentation for details.

Please refer to the debugging information in the Developer’s Handbook for more details about the debugging tools available.

Chapter 11. Upgrading a Port

When a port is not the most recent version available from the authors, update the local working copy of /usr/ports. The port might have already been updated to the new version.

When working with more than a few ports, it will probably be easier to use Git to keep the whole ports collection up-to-date, as described in Using the Ports Collection. This will have the added benefit of tracking all the port’s dependencies.

The next step is to see if there is an update already pending. To do this, there are two options. There is a searchable interface to the FreeBSD Problem Report (PR) or bug database. Select Ports & Packages in the Product multiple select menu, and enter the name of the port in the Summary field.

If there is no pending PR, the next step is to send an email to the port’s maintainer, as shown by make maintainer. That person may already be working on an upgrade, or have a reason to not upgrade the port right now (because of, for example, stability problems of the new version), and there is no need to duplicate their work. Note that unmaintained ports are listed with a maintainer of ports@FreeBSD.org, which is just the general ports mailing list, so sending mail there probably will not help in this case.

If the maintainer asks you to do the upgrade or there is no maintainer, then help out FreeBSD by preparing the update! Please do this by using the diff(1) command in the base system.

To create a suitable diff for a single patch, copy the file that needs patching to something.orig, save the changes to something and then create the patch:

% diff -u something.orig something > something.diff

Otherwise, either use the git diff method (Using Git to Make Patches) or copy the contents of the port to an entire different directory and use the result of the recursive diff(1) output of the new and old ports directories (for example, if the modified port directory is called superedit and the original is in our tree as superedit.bak, then save the result of diff -ruN superedit.bak superedit). Either unified or context diff is fine, but port committers generally prefer unified diffs. Note the use of the -N option-this is the accepted way to force diff to properly deal with the case of new files being added or old files being deleted. Before sending us the diff, please examine the output to make sure all the changes make sense. (In particular, make sure to first clean out the work directories with make clean).

If some files have been added, copied, moved, or removed, add this information to the problem report so that the committer picking up the patch will know what git(1) commands to run.

To simplify common operations with patch files, use make makepatch as described in Patching. Other tools exists, like /usr/ports/Tools/scripts/patchtool.py. Before using it, please read /usr/ports/Tools/scripts/README.patchtool.

If the port is unmaintained, and you are actively using it, please consider volunteering to become its maintainer. FreeBSD has over 4000 ports without maintainers, and this is an area where more volunteers are always needed. (For a detailed description of the responsibilities of maintainers, refer to the section in the Developer’s Handbook.)

To submit the diff, use the bug submit form (product Ports & Packages, component Individual Port(s)). Always include the category with the port name, followed by colon, and brief description of the issue. Examples: category/portname: add FOO option; category/portname: Update to X.Y. Please mention any added or deleted files in the message, as they have to be explicitly specified to git(1) when doing a commit. Do not compress or encode the diff.

Before submitting the bug, review the Writing the problem report section in the Problem Reports article. It contains far more information about how to write useful problem reports.

If the upgrade is motivated by security concerns or a serious fault in the currently committed port, please notify the Ports Management Team <portmgr@FreeBSD.org> to request immediate rebuilding and redistribution of the port’s package. Unsuspecting users of pkg will otherwise continue to install the old version via pkg install for several weeks.

Please use diff(1) or git diff to create updates to existing ports. Other formats include the whole file and make it impossible to see just what has changed. When diffs are not included, the entire update might be ignored.

Now that all of that is done, read about how to keep up-to-date in Keeping Up.

11.1. Using Git to Make Patches

When possible, please submit a git(1) patch or diff. They are easier to handle than diffs between "new and old" directories. It is easier to see what has changed, and to update the diff if something was modified in the Ports Collection since the work on it began, or if the committer asks for something to be fixed. Also, a patch generated with git-format-patch(1) or git-diff(1) can be easily applied with git-am(1) or git-apply(1) and will save some time for the committer. Finally, the git patch generated by git-format-patch(1) includes your author information and commit messages. These will be recorded in the log of the repository and this is the recommended way to submit your changes.

% git clone https://git.FreeBSD.org/ports.git ~/my_wrkdir  (1) (2)
% cd ~/my_wrkdir

1	This can be anywhere, of course. Building ports is not limited to within /usr/ports/.
2	git.FreeBSD.org is the FreeBSD public Git server. See FreeBSD Git Repository URL Table for more information.

While in the port directory, make any changes that are needed. If adding, moving, or removing a file, use git to track these changes:

% git add new_file
% git mv old_name new_name
% git rm deleted_file

Make sure to check the port using the checklist in Testing the Port and Checking the Port with portlint.

Also, update the checksum reference in distinfo with make makesum.

Before making the patch, fetch the latest repository and rebase the changes on top of it. Watch and follow the output carefully. If any of the files failed to rebase, it means that the upstream files changed while you were editing the same file, and the conflicts need to be resolved manually.

% git fetch origin main
% git rebase origin/main

Check the changes staged for the patch:

% git status
% git diff --staged

The last step is to make an unified diff or patch of the changes:

To generate a patch with git-format-patch(1):

% git checkout -b my_branch
% git commit
% git format-patch main

This will generate a patch named like 0001-foo.patch. This is the preferred way as it would include author identity, and it is also easier when you are making a series of changes that are not meant to be squashed together.

Alternatively, to generate an unified diff with git-diff(1):

% git diff --staged > ../`make -VPKGNAME`.diff

This will generate a diff named like foo-1.2.3.diff. Where foo is replaced with the first line of the commit message, i.e., the subject of the commit message.

After patch has been created, you can switch to the main branch for starting other developments.

% git checkout main

Once the patch is accepted and merged, you can delete the local development branch if you want:

% git branch -D my_branch

If files have been added, moved, or removed, include the git(1) add, mv, and rm commands that were used. git mv must be run before the patch can be applied. git add or git rm must be run after the patch is applied.

Send the patch following the problem report submission guidelines.

11.2. UPDATING and MOVED

11.2.1. /usr/ports/UPDATING

If upgrading the port requires special steps like changing configuration files or running a specific program, it must be documented in this file. The format of an entry in this file is:

YYYYMMDD:
  AFFECTS: users of portcategory/portname
  AUTHOR: Your name <Your email address>

  Special instructions

When including exact portmaster, portupgrade, and/or pkg instructions, please make sure to get the shell escaping right. For example, do not use:

# pkg delete -g -f docbook-xml* docbook-sk* docbook[2345]??-* docbook-4*

As shown, the command will only work with bourne shells. Instead, use the form shown below, which will work with both bourne shell and c-shell:

# pkg delete -g -f docbook-xml\* docbook-sk\* docbook\[2345\]\?\?-\* docbook-4\*

It is recommended that the AFFECTS line contains a glob matching all the ports affected by the entry so that automated tools can parse it as easily as possible. If an update concerns all the existing BIND 9 versions the AFFECTS content must be users of dns/bind9*, it must not be users of BIND 9

11.2.2. /usr/ports/MOVED

This file is used to list moved or removed ports. Each line in the file is made up of the name of the port, where the port was moved, when, and why. If the port was removed, the section detailing where it was moved can be left blank. Each section must be separated by the | (pipe) character, like so:

old name|new name (blank for deleted)|date of move|reason

The date must be entered in the form YYYY-MM-DD. New entries are added to the end of the list to keep it in chronological order, with the oldest entry at the top of the list.

If a port was removed but has since been restored, delete the line in this file that states that it was removed.

If a port was renamed and then renamed back to its original name, add a new one with the intermediate name to the old name, and remove the old entry as to not create a loop.

Any changes must be validated with Tools/scripts/MOVEDlint.awk.

If using a ports directory other than /usr/ports, use:

% cd /home/user/ports
% env PORTSDIR=$PWD Tools/scripts/MOVEDlint.awk

Chapter 12. Security

12.1. Why Security is So Important

Bugs are occasionally introduced to the software. Arguably, the most dangerous of them are those opening security vulnerabilities. From the technical viewpoint, such vulnerabilities are to be closed by exterminating the bugs that caused them. However, the policies for handling mere bugs and security vulnerabilities are very different.

A typical small bug affects only those users who have enabled some combination of options triggering the bug. The developer will eventually release a patch followed by a new version of the software, free of the bug, but the majority of users will not take the trouble of upgrading immediately because the bug has never vexed them. A critical bug that may cause data loss represents a graver issue. Nevertheless, prudent users know that a lot of possible accidents, besides software bugs, are likely to lead to data loss, and so they make backups of important data; in addition, a critical bug will be discovered really soon.

A security vulnerability is all different. First, it may remain unnoticed for years because often it does not cause software malfunction. Second, a malicious party can use it to gain unauthorized access to a vulnerable system, to destroy or alter sensitive data; and in the worst case the user will not even notice the harm caused. Third, exposing a vulnerable system often assists attackers to break into other systems that could not be compromised otherwise. Therefore closing a vulnerability alone is not enough: notify the audience of it in the most clear and comprehensive manner, which will allow them to evaluate the danger and take appropriate action.

12.2. Fixing Security Vulnerabilities

While on the subject of ports and packages, a security vulnerability may initially appear in the original distribution or in the port files. In the former case, the original software developer is likely to release a patch or a new version instantly. Update the port promptly with respect to the author’s fix. If the fix is delayed for some reason, either mark the port as FORBIDDEN or introduce a patch file to the port. In the case of a vulnerable port, just fix the port as soon as possible. In either case, follow the standard procedure for submitting changes unless having rights to commit it directly to the ports tree.

Being a ports committer is not enough to commit to an arbitrary port. Remember that ports usually have maintainers, must be respected.

Please make sure that the port’s revision is bumped as soon as the vulnerability has been closed. That is how the users who upgrade installed packages on a regular basis will see they need to run an update. Besides, a new package will be built and distributed over FTP and WWW mirrors, replacing the vulnerable one. Bump PORTREVISION unless DISTVERSION has changed in the course of correcting the vulnerability. That is, bump PORTREVISION if adding a patch file to the port, but do not bump it if updating the port to the latest software version and thus already touched DISTVERSION. Please refer to the corresponding section for more information.

12.3. Keeping the Community Informed

12.3.1. The VuXML Database

A very important and urgent step to take as early after a security vulnerability is discovered as possible is to notify the community of port users about the jeopardy. Such notification serves two purposes. First, if the danger is really severe it will be wise to apply an instant workaround. For example, stop the affected network service or even deinstall the port completely until the vulnerability is closed. Second, a lot of users tend to upgrade installed packages only occasionally. They will know from the notification that they must update the package without delay as soon as a corrected version is available.

Given the huge number of ports in the tree, a security advisory cannot be issued on each incident without creating a flood and losing the attention of the audience when it comes to really serious matters. Therefore security vulnerabilities found in ports are recorded in the FreeBSD VuXML database. The Security Officer Team members also monitor it for issues requiring their intervention.

Committers can update the VuXML database themselves, assisting the Security Officer Team and delivering crucial information to the community more quickly. Those who are not committers or have discovered an exceptionally severe vulnerability should not hesitate to contact the Security Officer Team directly, as described on the FreeBSD Security Information page.

The VuXML database is an XML document. Its source file vuln.xml is kept right inside the port security/vuxml. Therefore the file’s full pathname will be PORTSDIR/security/vuxml/vuln.xml. Each time a security vulnerability is discovered in a port, please add an entry for it to that file. Until familiar with VuXML, the best thing to do is to find an existing entry fitting the case at hand, then copy it and use it as a template.

12.3.2. A Short Introduction to VuXML

The full-blown XML format is complex, and far beyond the scope of this book. However, to gain basic insight on the structure of a VuXML entry only the notion of tags is needed. XML tag names are enclosed in angle brackets. Each opening <tag> must have a matching closing </tag>. Tags may be nested. If nesting, the inner tags must be closed before the outer ones. There is a hierarchy of tags, that is, more complex rules of nesting them. This is similar to HTML. The major difference is that XML is eXtensible, that is, based on defining custom tags. Due to its intrinsic structure XML puts otherwise amorphous data into shape. VuXML is particularly tailored to mark up descriptions of security vulnerabilities.

Now consider a realistic VuXML entry:

<vuln vid="f4bc80f4-da62-11d8-90ea-0004ac98a7b9"> (1)
  <topic>Several vulnerabilities found in Foo</topic> (2)

The tag names are supposed to be self-explanatory so we shall take a closer look only at fields which needs to be filled in:

1	This is the top-level tag of a VuXML entry. It has a mandatory attribute, `vid`, specifying a universally unique identifier (UUID) for this entry (in quotes). Generate a UUID for each new VuXML entry (and do not forget to substitute it for the template UUID unless writing the entry from scratch). Use uuidgen(1) to generate a VuXML UUID.
2	This is a one-line description of the issue found.
3	The names of packages affected are listed there. Multiple names can be given since several packages may be based on a single master port or software product. This may include stable and development branches, localized versions, and slave ports featuring different choices of important build-time configuration options.
4	Affected versions of the package(s) are specified there as one or more ranges using a combination of `<lt>`, `<le>`, `<eq>`, `<ge>`, and `<gt>` elements. Check that the version ranges given do not overlap. In a range specification, `` (asterisk) denotes the smallest version number. In particular, `2.` is less than `2.a`. Therefore an asterisk may be used for a range to match all possible `alpha`, `beta`, and `RC` versions. For instance, `<ge>2.</ge><lt>3.</lt>` will selectively match every `2.x` version while `<ge>2.0</ge><lt>3.0</lt>` will not since the latter misses `2.r3` and matches `3.b`. The above example specifies that affected are versions `1.6` and up to but not including `1.9`, versions `2.x` before `2.4_1`, and version `3.0b1`.
5	Several related package groups (essentially, ports) can be listed in the `<affected>` section. This can be used if several software products (say FooBar, FreeBar and OpenBar) grow from the same code base and still share its bugs and vulnerabilities. Note the difference from listing multiple names within a single <package> section.
6	The version ranges have to allow for `PORTEPOCH` and `PORTREVISION` if applicable. Please remember that according to the collation rules, a version with a non-zero `PORTEPOCH` is greater than any version without `PORTEPOCH`, for example, `3.0,1` is greater than `3.1` or even than `8.9`.
7	This is a summary of the issue. XHTML is used in this field. At least enclosing `<p>` and `</p>` has to appear. More complex mark-up may be used, but only for the sake of accuracy and clarity: No eye candy please.
8	This section contains references to relevant documents. As many references as apply are encouraged.
9	This is a FreeBSD security advisory.
10	This is a FreeBSD problem report.
11	This is a MITRE CVE identifier.
12	This is a US-CERT vulnerability note.
13	This is a US-CERT Technical Cyber Security Alert.
14	This is a URL to an archived posting in a mailing list. The attribute `msgid` is optional and may specify the message ID of the posting.
15	This is a generic URL. Only it if none of the other reference categories apply.
16	This is the date when the issue was disclosed (YYYY-MM-DD).
17	This is the date when the entry was added (YYYY-MM-DD).
18	This is the date when any information in the entry was last modified (YYYY-MM-DD). New entries must not include this field. Add it when editing an existing entry.

12.3.3. Testing Changes to the VuXML Database

This example describes a new entry for a vulnerability in the package dropbear that has been fixed in version dropbear-2013.59.

As a prerequisite, install a fresh version of security/vuxml port.

First, check whether there already is an entry for this vulnerability. If there were such an entry, it would match the previous version of the package, 2013.58:

% pkg audit dropbear-2013.58

If there is none found, add a new entry for this vulnerability.

% cd ${PORTSDIR}/security/vuxml
% make newentry

If the vulnerability has a MITRE CVE identifier, the following command can be used instead:

% cd ${PORTSDIR}/security/vuxml
% make newentry CVE_ID=CVE-YYYY-XXXXX

where CVE-YYYYY-XXXX is a valid CVE identifier.

If the vulnerability is a FreeBSD Security Advisory, the following command can be used instead:

% cd ${PORTSDIR}/security/vuxml
% make newentry SA_ID=FreeBSD-SA-YY-XXXXXX.asc

where FreeBSD-SA-YY-XXXXXX.asc is a published FreeBSD Security Advisory.

Verify its syntax and formatting:

% make validate

The previous command generates the vuln-flat.xml file. It can also be generated with:

% make vuln-flat.xml

At least one of these packages needs to be installed: textproc/libxml2, textproc/jade.

Verify that the <affected> section of the entry will match the correct packages:

% pkg audit -f ${PORTSDIR}/security/vuxml/vuln-flat.xml dropbear-2013.58

Make sure that the entry produces no spurious matches in the output.

Now check whether the right package versions are matched by the entry:

% pkg audit -f ${PORTSDIR}/security/vuxml/vuln-flat.xml dropbear-2013.58 dropbear-2013.59
dropbear-2012.58 is vulnerable:
dropbear -- exposure of sensitive information, DoS
CVE: CVE-2013-4434
CVE: CVE-2013-4421
WWW: https://portaudit.FreeBSD.org/8c9b48d1-3715-11e3-a624-00262d8b701d.html

1 problem(s) in the installed packages found.

The former version matches while the latter one does not.

Chapter 13. Dos and Don’ts

13.1. Introduction

Here is a list of common dos and don’ts that are encountered during the porting process. Check the port against this list, but also check ports in the PR database that others have submitted. Submit any comments on ports as described in Bug Reports and General Commentary. Checking ports in the PR database will both make it faster for us to commit them, and prove that you know what you are doing.

13.2. `WRKDIR`

Do not write anything to files outside WRKDIR. WRKDIR is the only place that is guaranteed to be writable during the port build (see installing ports from a CDROM for an example of building ports from a read-only tree). The pkg-* files can be modified by redefining a variable rather than overwriting the file.

13.3. `WRKDIRPREFIX`

Make sure the port honors WRKDIRPREFIX. Most ports do not have to worry about this. In particular, when referring to a WRKDIR of another port, note that the correct location is ${WRKDIRPREFIX}${PORTSDIR}/subdir/name/work not ${PORTSDIR}/subdir/name/work or ${.CURDIR}/../../subdir/name/work or some such.

13.4. Differentiating Operating Systems and OS Versions

Some code needs modifications or conditional compilation based upon what version of FreeBSD Unix it is running under. The preferred way to tell FreeBSD versions apart are the __FreeBSD_version and __FreeBSD__ macros defined in sys/param.h. If this file is not included add the code,

#include <sys/param.h>

to the proper place in the .c file.

__FreeBSD__ is defined in all versions of FreeBSD as their major version number. For example, in FreeBSD 9.x, __FreeBSD__ is defined to be 9.

#if __FreeBSD__ >= 9
#  if __FreeBSD_version >= 901000
	 /* 9.1+ release specific code here */
#  endif
#endif

A complete list of __FreeBSD_version values is available in __FreeBSD_version Values.

13.5. Writing Something After bsd.port.mk

Do not write anything after the .include <bsd.port.mk> line. It usually can be avoided by including bsd.port.pre.mk somewhere in the middle of the Makefile and bsd.port.post.mk at the end.

Include either the bsd.port.pre.mk/bsd.port.post.mk pair or bsd.port.mk only; do not mix these two usages.

bsd.port.pre.mk only defines a few variables, which can be used in tests in the Makefile, bsd.port.post.mk defines the rest.

Here are some important variables defined in bsd.port.pre.mk (this is not the complete list, please read bsd.port.mk for the complete list).

Variable Description

ARCH

The architecture as returned by uname -m (for example, i386)

OPSYS

The operating system type, as returned by uname -s (for example, FreeBSD)

OSREL

The release version of the operating system (for example, 2.1.5 or 2.2.7)

OSVERSION

The numeric version of the operating system; the same as __FreeBSD_version.

LOCALBASE

The base of the "local" tree (for example, /usr/local)

PREFIX

Where the port installs itself (see more on PREFIX).

When MASTERDIR is needed, always define it before including bsd.port.pre.mk.

Here are some examples of things that can be added after bsd.port.pre.mk:

# no need to compile lang/perl5 if perl5 is already in system
.if ${OSVERSION} > 300003
BROKEN=	perl is in system
.endif

Always use tab instead of spaces after BROKEN=.

13.6. Use the `exec` Statement in Wrapper Scripts

If the port installs a shell script whose purpose is to launch another program, and if launching that program is the last action performed by the script, make sure to launch the program using the exec statement, for instance:

#!/bin/sh
exec %%LOCALBASE%%/bin/java -jar %%DATADIR%%/foo.jar "$@"

The exec statement replaces the shell process with the specified program. If exec is omitted, the shell process remains in memory while the program is executing, and needlessly consumes system resources.

13.7. Do Things Rationally

The Makefile should do things in a simple and reasonable manner. Making it a couple of lines shorter or more readable is always better. Examples include using a make .if construct instead of a shell if construct, not redefining do-extract if redefining EXTRACT* is enough, and using GNU_CONFIGURE instead of CONFIGURE_ARGS += --prefix=${PREFIX}.

If a lot of new code is needed to do something, there may already be an implementation of it in bsd.port.mk. While hard to read, there are a great many seemingly-hard problems for which bsd.port.mk already provides a shorthand solution.

13.8. Respect Both `CC` and `CXX`

The port must respect both CC and CXX. What we mean by this is that the port must not set the values of these variables absolutely, overriding existing values; instead, it may append whatever values it needs to the existing values. This is so that build options that affect all ports can be set globally.

If the port does not respect these variables, please add NO_PACKAGE=ignores either cc or cxx to the Makefile.

Here is an example of a Makefile respecting both CC and CXX. Note the ?=:

CC?= gcc

CXX?= g++

Here is an example which respects neither CC nor CXX:

CC= gcc

CXX= g++

Both CC and CXX can be defined on FreeBSD systems in /etc/make.conf. The first example defines a value if it was not previously set in /etc/make.conf, preserving any system-wide definitions. The second example clobbers anything previously defined.

13.9. Respect `CFLAGS`

The port must respect CFLAGS. What we mean by this is that the port must not set the value of this variable absolutely, overriding the existing value. Instead, it may append whatever values it needs to the existing value. This is so that build options that affect all ports can be set globally.

If it does not, please add NO_PACKAGE=ignores cflags to the Makefile.

Here is an example of a Makefile respecting CFLAGS. Note the +=:

CFLAGS+= -Wall -Werror

Here is an example which does not respect CFLAGS:

CFLAGS= -Wall -Werror

CFLAGS is defined on FreeBSD systems in /etc/make.conf. The first example appends additional flags to CFLAGS, preserving any system-wide definitions. The second example clobbers anything previously defined.

Remove optimization flags from the third party Makefiles. The system CFLAGS contains system-wide optimization flags. An example from an unmodified Makefile:

CFLAGS= -O3 -funroll-loops -DHAVE_SOUND

Using system optimization flags, the Makefile would look similar to this example:

CFLAGS+= -DHAVE_SOUND

13.10. Verbose Build Logs

Make the port build system display all commands executed during the build stage. Complete build logs are crucial to debugging port problems.

Non-informative build log example (bad):

  CC     source1.o
  CC     source2.o
  CCLD   someprogram

Verbose build log example (good):

cc -O2 -pipe -I/usr/local/include -c -o source1.o source1.c
cc -O2 -pipe -I/usr/local/include -c -o source2.o source2.c
cc -o someprogram source1.o source2.o -L/usr/local/lib -lsomelib

Some build systems such as CMake, ninja, and GNU configure are set up for verbose logging by the ports framework. In other cases, ports might need individual tweaks.

13.11. Feedback

Do send applicable changes and patches to the upstream maintainer for inclusion in the next release of the code. This makes updating to the next release that much easier.

13.12. README.html

README.html is not part of the port, but generated by make readme. Do not include this file in patches or commits.

If make readme fails, make sure that the default value of ECHO_MSG has not been modified by the port.

13.13. Marking a Port Not Installable with `BROKEN`, `FORBIDDEN`, or `IGNORE`

In certain cases, users must be prevented from installing a port. There are several variables that can be used in a port’s Makefile to tell the user that the port cannot be installed. The value of these make variables will be the reason that is shown to users for why the port refuses to install itself. Please use the correct make variable. Each variable conveys radically different meanings, both to users and to automated systems that depend on Makefiles, such as the ports build cluster, and FreshPorts.

13.13.1. Variables

BROKEN is reserved for ports that currently do not compile, install, deinstall, or run correctly. Use it for ports where the problem is believed to be temporary.
If instructed, the build cluster will still attempt to try to build them to see if the underlying problem has been resolved. (However, in general, the cluster is run without this.)
For instance, use BROKEN when a port:
- does not compile
- fails its configuration or installation process
- installs files outside of ${PREFIX}
- does not remove all its files cleanly upon deinstall (however, it may be acceptable, and desirable, for the port to leave user-modified files behind)
- has runtime issues on systems where it is supposed to run fine.
FORBIDDEN is used for ports that contain a security vulnerability or induce grave concern regarding the security of a FreeBSD system with a given port installed (for example, a reputably insecure program or a program that provides easily exploitable services). Mark ports as FORBIDDEN as soon as a particular piece of software has a vulnerability and there is no released upgrade. Ideally upgrade ports as soon as possible when a security vulnerability is discovered so as to reduce the number of vulnerable FreeBSD hosts (we like being known for being secure), however sometimes there is a noticeable time gap between disclosure of a vulnerability and an updated release of the vulnerable software. Do not mark a port FORBIDDEN for any reason other than security.

IGNORE is reserved for ports that must not be built for some other reason. Use it for ports where the problem is believed to be structural. The build cluster will not, under any circumstances, build ports marked as IGNORE. For instance, use IGNORE when a port:

does not work on the installed version of FreeBSD
has a distfile which may not be automatically fetched due to licensing restrictions

does not work with some other currently installed port (for instance, the port depends on www/drupal7 but www/drupal8 is installed)

If a port would conflict with a currently installed port (for example, if they install a file in the same place that performs a different function), use CONFLICTS instead. CONFLICTS will set IGNORE by itself.

13.13.2. Implementation Notes

Do not quote the values of BROKEN, IGNORE, and related variables. Due to the way the information is shown to the user, the wording of messages for each variable differ:

BROKEN=	fails to link with base -lcrypto

IGNORE=	unsupported on recent versions

resulting in this output from make describe:

===>  foobar-0.1 is marked as broken: fails to link with base -lcrypto.

===>  foobar-0.1 is unsupported on recent versions.

13.14. Architectural Considerations

13.14.1. General Notes on Architectures

FreeBSD runs on many more processor architectures than just the well-known x86-based ones. Some ports have constraints which are particular to one or more of these architectures.

For the list of supported architectures, run:

cd ${SRCDIR}; make targets

The values are shown in the form TARGET/TARGET_ARCH. The ports read-only makevar ARCH is set based on the value of TARGET_ARCH. Port Makefiles should test the value of this Makevar.

13.14.2. Marking a Port as Architecture Neutral

Ports that do not have any architecture-dependent files or requirements are identified by setting NO_ARCH=yes.

Packages built from such ports have their architecture string ending in :* (wildcard architecture) as opposed to, for example, freebsd:13:x86:64 (amd64 architecture).

NO_ARCH is meant to indicate that there is no need to build a package for each of the supported architectures. The goal is to reduce the amount of resources spent on building and distributing the packages such as network bandwidth and disk space on mirrors and on distribution media. Currently, however, our package infrastructure (e.g., package managers, mirrors, and package builders) is not set up to fully benefit from NO_ARCH.

13.14.3. Marking a Port as Ignored Only On Certain Architectures

To mark a port as IGNOREd only on certain architectures, there are two other convenience variables that will automatically set IGNORE: ONLY_FOR_ARCHS and NOT_FOR_ARCHS. Examples:
```
ONLY_FOR_ARCHS=	i386 amd64
```
```
NOT_FOR_ARCHS=	ia64 sparc64
```
A custom IGNORE message can be set using ONLY_FOR_ARCHS_REASON and NOT_FOR_ARCHS_REASON. Per architecture entries are possible with ONLY_FOR_ARCHS_REASON_ARCH and NOT_FOR_ARCHS_REASON_ARCH.

If a port fetches i386 binaries and installs them, set IA32_BINARY_PORT. If this variable is set, /usr/lib32 must be present for IA32 versions of libraries and the kernel must support IA32 compatibility. If one of these two dependencies is not satisfied, IGNORE will be set automatically.

13.14.4. Cluster-Specific Considerations

Some ports attempt to tune themselves to the exact machine they are being built on by specifying -march=native to the compiler. This should be avoided: either list it under an off-by-default option, or delete it entirely.
Otherwise, the default package produced by the build cluster might not run on every single machine of that ARCH.

13.15. Marking a Port for Removal with `DEPRECATED` or `EXPIRATION_DATE`

Do remember that BROKEN and FORBIDDEN are to be used as a temporary resort if a port is not working. Permanently broken ports will be removed from the tree entirely.

When it makes sense to do so, users can be warned about a pending port removal with DEPRECATED and EXPIRATION_DATE. The former is a string stating why the port is scheduled for removal; the latter is a string in ISO 8601 format (YYYY-MM-DD). Both will be shown to the user.

It is possible to set DEPRECATED without an EXPIRATION_DATE (for instance, recommending a newer version of the port), but the converse does not make any sense.

When marking a port as DEPRECATED, if there are any alternative ports that can be used as a replacement for the one being deprecated, it is convenient to mention them in the commit message.

There is no set policy on how much notice to give. Current practice seems to be one month for security-related issues and two months for build issues. This also gives any interested committers a little time to fix the problems.

13.16. Avoid Use of the `.error` Construct

The correct way for a Makefile to signal that the port cannot be installed due to some external factor (for instance, the user has specified an illegal combination of build options) is to set a non-blank value to IGNORE. This value will be formatted and shown to the user by make install.

It is a common mistake to use .error for this purpose. The problem with this is that many automated tools that work with the ports tree will fail in this situation. The most common occurrence of this is seen when trying to build /usr/ports/INDEX (see Running make describe). However, even more trivial commands such as make maintainer also fail in this scenario. This is not acceptable.

Example 115. How to Avoid Using .error

The first of the next two Makefile snippets will cause make index to fail, while the second one will not:

.error "option is not supported"

IGNORE=option is not supported

13.17. Usage of sysctl

The usage of sysctl is discouraged except in targets. This is because the evaluation of any makevars, such as used during make index, then has to run the command, further slowing down that process.

Only use sysctl(8) through SYSCTL, as it contains the fully qualified path and can be overridden, if one has such a special need.

13.18. Rerolling Distfiles

Sometimes the authors of software change the content of released distfiles without changing the file’s name. Verify that the changes are official and have been performed by the author. It has happened in the past that the distfile was silently altered on the download servers with the intent to cause harm or compromise end user security.

Put the old distfile aside, download the new one, unpack them and compare the content with diff(1). If there is nothing suspicious, update distinfo.

Be sure to summarize the differences in the PR and commit log, so that other people know that nothing bad has happened.

Contact the authors of the software and confirm the changes with them.

13.19. Use POSIX Standards

FreeBSD ports generally expect POSIX compliance. Some software and build systems make assumptions based on a particular operating system or environment that can cause problems when used in a port.

Do not use /proc if there are any other ways of getting the information. For example, setprogname(argv[0]) in main() and then getprogname(3) to know the executable name.

Do not rely on behavior that is undocumented by POSIX.

Do not record timestamps in the critical path of the application if it also works without. Getting timestamps may be slow, depending on the accuracy of timestamps in the OS. If timestamps are really needed, determine how precise they have to be and use an API which is documented to just deliver the needed precision.

A number of simple syscalls (for example gettimeofday(2), getpid(2)) are much faster on Linux® than on any other operating system due to caching and the vsyscall performance optimizations. Do not rely on them being cheap in performance-critical applications. In general, try hard to avoid syscalls if possible.

Do not rely on Linux®-specific socket behavior. In particular, default socket buffer sizes are different (call setsockopt(2) with SO_SNDBUF and SO_RCVBUF, and while Linux®'s send(2) blocks when the socket buffer is full, FreeBSD’s will fail and set ENOBUFS in errno.

If relying on non-standard behavior is required, encapsulate it properly into a generic API, do a check for the behavior in the configure stage, and stop if it is missing.

Check the man pages to see if the function used is a POSIX interface (in the "STANDARDS" section of the man page).

Do not assume that /bin/sh is bash. Ensure that a command line passed to system(3) will work with a POSIX compliant shell.

A list of common bashisms is available here.

Check that headers are included in the POSIX or man page recommended way. For example, sys/types.h is often forgotten, which is not as much of a problem for Linux® as it is for FreeBSD.

13.20. Miscellanea

Always double-check pkg-descr and pkg-plist. If reviewing a port and a better wording can be achieved, do so.

Please be careful to note any legal issues! Do not let us illegally distribute software!

Chapter 14. A Sample Makefile

Here is a sample Makefile that can be used to create a new port. Make sure to remove all the extra comments (ones between brackets).

The format shown is the recommended one for ordering variables, empty lines between sections, and so on. This format is designed so that the most important information is easy to locate. We recommend using portlint to check the Makefile.

[section to describe the port itself and the master site - PORTNAME
 and PORTVERSION or the DISTVERSION* variables are always first,
 followed by CATEGORIES, and then MASTER_SITES, which can be followed
 by MASTER_SITE_SUBDIR.  PKGNAMEPREFIX and PKGNAMESUFFIX, if needed,
 will be after that.  Then comes DISTNAME, EXTRACT_SUFX and/or
 DISTFILES, and then EXTRACT_ONLY, as necessary.]

Chapter 15. Order of Variables in Port Makefiles

The first sections of the Makefile must always come in the same order. This standard makes it so everyone can easily read any port without having to search for variables in a random order.

The sections and variables described here are mandatory in a ordinary port. In a slave port, many sections and variables can be skipped.

Each following block must be separated from the previous block by a single blank line.

In the following blocks, only set the variables that are required by the port. Define these variables in the order they are shown here.

15.1. `PORTNAME` Block

This block is the most important. It defines the port name, version, distribution file location, and category. The variables must be in this order:

Only one of PORTVERSION and DISTVERSION can be used.

15.2. `PATCHFILES` Block

This block is optional. The variables are:

15.3. `MAINTAINER` Block

This block is mandatory. The variables are:

15.4. `LICENSE` Block

This block is optional, although it is highly recommended. The variables are:

LICENSE
LICENSE_COMB
LICENSE_GROUPS or LICENSE_GROUPS_NAME
LICENSE_NAME or LICENSE_NAME_NAME
LICENSE_TEXT or LICENSE_TEXT_NAME
LICENSE_FILE or LICENSE_FILE_NAME
LICENSE_PERMS or LICENSE_PERMS_NAME_
LICENSE_DISTFILES or LICENSE_DISTFILES_NAME

If there are multiple licenses, sort the different LICENSE_VAR_NAME variables by license name.

15.5. Generic `BROKEN`/`IGNORE`/`DEPRECATED` Messages

This block is optional. The variables are:

BROKEN_* and IGNORE_* can be any generic variables, for example, IGNORE_amd64, BROKEN_FreeBSD_10, etc. With the exception of variables that depend on a USES, place those in USES and USE_x. For instance, IGNORE_WITH_PHP only works if php is set, and BROKEN_SSL only if ssl is set.

If the port is marked BROKEN when some conditions are met, and such conditions can only be tested after including bsd.port.options.mk or bsd.port.pre.mk, then those variables should be set later, in The Rest of the Variables.

15.6. The Dependencies Block

This block is optional. The variables are:

15.7. Flavors

This block is optional.

Start this section with defining FLAVORS. Continue with the possible Flavors helpers. See Using FLAVORS for more Information.

Constructs setting variables not available as helpers using .if ${FLAVOR:U} == foo should go in their respective sections below.

15.8. `USES` and `USE_x`

Start this section with defining USES, and then possible USE_x.

Keep related variables close together. For example, if using USE_GITHUB, always put the GH_* variables right after it.

15.9. Standard bsd.port.mk Variables

This section block is for variables that can be defined in bsd.port.mk that do not belong in any of the previous section blocks.

Order is not important, however try to keep similar variables together. For example uid and gid variables USERS and GROUPS. Configuration variables CONFIGURE_* and *_CONFIGURE. List of files, and directories PORTDOCS and PORTEXAMPLES.

15.10. Options and Helpers

If the port uses the options framework, define OPTIONS_DEFINE and OPTIONS_DEFAULT first, then the other OPTIONS_* variables first, then the *_DESC descriptions, then the options helpers. Try and sort all of those alphabetically.

Example 116. Options Variables Order Example

The FOO and BAR options do not have a standard description, so one need to be written. The other options already have one in Mk/bsd.options.desc.mk so writing one is not needed. The DOCS and EXAMPLES use target helpers to install their files, they are shown here for completeness, though they belong in The Targets, so other variables and targets could be inserted before them.

OPTIONS_DEFINE=	DOCS EXAMPLES FOO BAR
OPTIONS_DEFAULT=	FOO
OPTIONS_RADIO=	SSL
OPTIONS_RADIO_SSL=    OPENSSL GNUTLS
OPTIONS_SUB=	yes

BAR_DESC=		Enable bar support
FOO_DESC=		Enable foo support

BAR_CONFIGURE_WITH=	bar=${LOCALBASE}
FOO_CONFIGURE_ENABLE=	foo
GNUTLS_CONFIGURE_ON=	--with-ssl=gnutls
OPENSSL_CONFIGURE_ON=	--with-ssl=openssl

post-install-DOCS-on:
      ${MKDIR} ${STAGEDIR}${DOCSDIR}
      cd ${WRKSRC}/doc && ${COPYTREE_SHARE} . ${STAGEDIR}${DOCSDIR}

post-install-EXAMPLES-on:
      ${MKDIR} ${STAGEDIR}${EXAMPLESDIR}
      cd ${WRKSRC}/ex && ${COPYTREE_SHARE} . ${STAGEDIR}${EXAMPLESDIR}

15.11. The Rest of the Variables

And then, the rest of the variables that are not mentioned in the previous blocks.

15.12. The Targets

After all the variables are defined, the optional make(1) targets can be defined. Keep pre- before post- and in the same order as the different stages run:

fetch
extract
patch
configure
build
install
test

When using options helpers target keep them alphabetically sorted, but keep the -on before the -off. When also using the main target, keep the main target before the optional ones:

post-install:
	# install generic bits

post-install-DOCS-on:
	# Install documentation

post-install-X11-on:
	# Install X11 related bits

post-install-X11-off:
	# Install bits that should be there if X11 is disabled

Chapter 16. Keeping Up

The FreeBSD Ports Collection is constantly changing. Here is some information on how to keep up.

16.1. FreshPorts

One of the easiest ways to learn about updates that have already been committed is by subscribing to FreshPorts. Multiple ports can be monitored. Maintainers are strongly encouraged to subscribe, because they will receive notification of not only their own changes, but also any changes that any other FreeBSD committer has made. (These are often necessary to keep up with changes in the underlying ports framework-although it would be most polite to receive an advance heads-up from those committing such changes, sometimes this is overlooked or impractical. Also, in some cases, the changes are very minor in nature. We expect everyone to use their best judgement in these cases.)

To use FreshPorts, an account is required. Those with registered email addresses at @FreeBSD.org will see the opt-in link on the right-hand side of the web pages. Those who already have a FreshPorts account but are not using a @FreeBSD.org email address can change the email to @FreeBSD.org, subscribe, then change it back again.

FreshPorts also has a sanity test feature which automatically tests each commit to the FreeBSD ports tree. If subscribed to this service, a committer will receive notifications of any errors which FreshPorts detects during sanity testing of their commits.

16.2. The Web Interface to the Source Repository

It is possible to browse the files in the source repository by using a web interface. Changes that affect the entire port system are now documented in the CHANGES file. Changes that affect individual ports are now documented in the UPDATING file. However, the definitive answer to any question is undoubtedly to read the source code of bsd.port.mk, and associated files.

16.3. The FreeBSD Ports Mailing List

As a ports maintainer, consider subscribing to FreeBSD ports mailing list. Important changes to the way ports work will be announced there, and then committed to CHANGES.

If the volume of messages on this mailing list is too high, consider following FreeBSD ports announce mailing list which contains only announcements.

16.4. The FreeBSD Port Building Cluster

One of the least-publicized strengths of FreeBSD is that an entire cluster of machines is dedicated to continually building the Ports Collection, for each of the major OS releases and for each Tier-1 architecture.

Individual ports are built unless they are specifically marked with IGNORE. Ports that are marked with BROKEN will still be attempted, to see if the underlying problem has been resolved. (This is done by passing TRYBROKEN to the port’s Makefile.)

16.5. Portscout: the FreeBSD Ports Distfile Scanner

The build cluster is dedicated to building the latest release of each port with distfiles that have already been fetched. However, as the Internet continually changes, distfiles can quickly go missing. Portscout, the FreeBSD Ports distfile scanner, attempts to query every download site for every port to find out if each distfile is still available. Portscout can generate HTML reports and send emails about newly available ports to those who request them. Unless not otherwise subscribed, maintainers are asked to check periodically for changes, either by hand or using the RSS feed.

Portscout’s first page gives the email address of the port maintainer, the number of ports the maintainer is responsible for, the number of those ports with new distfiles, and the percentage of those ports that are out-of-date. The search function allows for searching by email address for a specific maintainer, and for selecting whether only out-of-date ports are shown.

Upon clicking on a maintainer’s email address, a list of all of their ports is displayed, along with port category, current version number, whether or not there is a new version, when the port was last updated, and finally when it was last checked. A search function on this page allows the user to search for a specific port.

Clicking on a port name in the list displays the FreshPorts port information.

Additional documentation is available in the Portscout repository.

Chapter 17. Using `USES` Macros

17.1. An Introduction to `USES`

USES macros make it easy to declare requirements and settings for a port. They can add dependencies, change building behavior, add metadata to packages, and so on, all by selecting simple, preset values.

Each section in this chapter describes a possible value for USES, along with its possible arguments. Arguments are appended to the value after a colon (:). Multiple arguments are separated by commas (,).

Example 117. Using Multiple Values

USES=	bison perl

Example 118. Adding an Argument

USES=	tar:xz

Example 119. Adding Multiple Arguments

USES=	drupal:7,theme

Example 120. Mixing it All Together

USES=	pgsql:9.3+ cpe python:2.7,build

17.2. `7z`

Possible arguments: (none), p7zip, partial

Extract using 7z(1) instead of bsdtar(1) and sets EXTRACT_SUFX=.7z. The p7zip option forces a dependency on the 7z from archivers/p7zip if the one from the base system is not able to extract the files. EXTRACT_SUFX is not changed if the partial option is used, this can be used if the main distribution file does not have a .7z extension.

17.3. `ada`

Possible arguments: (none), 6, 12, (run)

Depends on an Ada-capable compiler, and sets CC accordingly. Defaults to use gcc6-aux from ports.

17.4. `autoreconf`

Possible arguments: (none), build

Runs autoreconf. It encapsulates the aclocal, autoconf, autoheader, automake, autopoint, and libtoolize commands. Each command applies to ${AUTORECONF_WRKSRC}/configure.ac or its old name, ${AUTORECONF_WRKSRC}/configure.in. If configure.ac defines subdirectories with their own configure.ac using AC_CONFIG_SUBDIRS, autoreconf will recursively update those as well. The :build argument only adds build time dependencies on those tools but does not run autoreconf. A port can set AUTORECONF_WRKSRC if WRKSRC does not contain the path to configure.ac.

17.5. `blaslapack`

Possible arguments: (none), atlas, netlib (default), gotoblas, openblas

Adds dependencies on Blas / Lapack libraries.

17.6. `bdb`

Possible arguments: (none), 48, 5 (default), 6

Add dependency on the Berkeley DB library. Default to databases/db5. It can also depend on databases/db48 when using the :48 argument or databases/db6 with :6. It is possible to declare a range of acceptable values, :48+ finds the highest installed version, and falls back to 4.8 if nothing else is installed. INVALID_BDB_VER can be used to specify versions which do not work with this port. The framework exposes the following variables to the port:

BDB_LIB_NAME: The name of the Berkeley DB library. For example, when using databases/db5, it contains db-5.3.
BDB_LIB_CXX_NAME: The name of the Berkeley DBC++ library. For example, when using databases/db5, it contains db_cxx-5.3.
BDB_INCLUDE_DIR: The location of the Berkeley DB include directory. For example, when using databases/db5, it will contain ${LOCALBASE}/include/db5.
BDB_LIB_DIR: The location of the Berkeley DB library directory. For example, when using databases/db5, it contains ${LOCALBASE}/lib.
BDB_VER: The detected Berkeley DB version. For example, if using USES=bdb:48+ and Berkeley DB 5 is installed, it contains 5.

databases/db48 is deprecated and unsupported. It must not be used by any port.

17.7. `bison`

Possible arguments: (none), build, run, both

Uses devel/bison By default, with no arguments or with the build argument, it implies bison is a build-time dependency, run implies a run-time dependency, and both implies both run-time and build-time dependencies.

17.8. `budgie`

Possible arguments: (none)

Provide support for the Budgie desktop environment. Use USE_BUDGIE to select the components needed for the port. See Using Budgie for more information.

17.9. `cabal`

Ports should not be created for Haskell libraries, see Haskell Libraries for more information.

Possible arguments: (none), hpack, nodefault

Sets default values and targets used to build Haskell software using Cabal. A build dependency on the Haskell compiler port (lang/ghc) is added. If there is some other version of GHC already listed in the BUILD_DEPENDS variable (for example, lang/ghc810), it would be used instead. If the hpack argument is given, a build dependency on devel/hs-hpack is added and hpack is invoked at configuration step to generate .cabal file. If the nodefault argument is given, the framework will not try to pull the main distribution file from the Hackage. This argument is implicitly added if USE_GITHUB or USE_GITLAB is present.

The framework provides the following variables:

CABAL_REVISION

Haskell packages hosted on Hackage may have revisions. Set this knob to an integer number to pull in revised package description.

USE_CABAL

If the software uses Haskell dependencies, list them in this variable. Each item should be present on Hackage and be listed in form packagename-0.1.2. Dependencies can have revisions too, which are specified after the _ symbol. Automatic generation of the dependency list is supported, see Building Haskell Applications with cabal.

CABAL_FLAGS

List of flags to be passed to cabal-install during the configuring and building stage. The flags are passed verbatim. This variable is usually used to enable or disable flags that are declared in the .cabal file. Pass foo to enable the foo flag and -foo to disable it.

CABAL_EXECUTABLES

List of executable files installed by the port. Default value: ${PORTNAME}. Consult the .cabal file of the project being ported to get a list of possible values for this variable. Each value corresponds to an executable stanza in the .cabal file. Items from this list are automatically added to pkg-plist.

SKIP_CABAL_PLIST

If defined, do not add items from ${CABAL_EXECUTABLES} to pkg-plist.

opt_USE_CABAL

Adds items to ${USE_CABAL} depending on opt option.

opt_CABAL_EXECUTABLES

Adds items to ${CABAL_EXECUTABLES} depending on opt option.

opt_CABAL_FLAGS

If opt is enabled, append the value to ${CABAL_FLAGS}. Otherwise, append -value to disable the flag. Note that this behavior is slightly different from the plain CABAL_FLAGS as it does not accept values starting with -.

CABAL_WRAPPER_SCRIPTS

A subset of ${CABAL_EXECUTABLES} containing Haskell programs to be wrapped into a shell script that sets *_datadir environment variables before running the program. This also causes the actual Haskell binary to be installed under libexec/cabal/ directory. This knob is needed for Haskell programs that install their data files under share/ directory.

FOO_DATADIR_VARS

List of extra Haskell packages, whose data files should be accessible by the executable named FOO. The executable should be a part of ${CABAL_WRAPPER_SCRIPTS}. Haskell packages listed there should not have a version suffix.

CABAL_PROJECT

Some Haskell projects may already have a cabal.project file, which is also generated by the ports framework. If that is the case, use this variable to specify what to do with the original cabal.project. Setting this variable to remove will cause the original file to be removed. Setting this variable to append will:

Move the original file to cabal.project.${PORTNAME} during the extract stage.
Concatenate the original cabal.project.${PORTNAME} and the generated cabal.project into a single file after the patch stage. Using append makes it possible to perform patching on the original file before it gets merged.

17.10. `cargo`

Possible arguments: (none)

Uses Cargo for configuring, building, and testing. It can be used to port Rust applications that use the Cargo build system. For more information see Building Rust Applications with cargo.

17.11. `charsetfix`

Possible arguments: (none)

Prevents the port from installing charset.alias. This must be installed only by converters/libiconv. CHARSETFIX_MAKEFILEIN can be set to a path relative to WRKSRC if charset.alias is not installed by ${WRKSRC}/Makefile.in.

17.12. `cmake`

Possible arguments: (none), insource, noninja, run, testing

Use CMake for configuring the port and generating a build system.

By default an out-of-source build is performed, leaving the sources in WRKSRC free from build artifacts. With the insource argument, an in-source build will be performed instead. This argument should be an exception, used only when a regular out-of-source build does not work.

By default Ninja (devel/ninja) is used for the build. In some cases this does not work correctly. With the noninja argument, the build will use regular make for builds. This argument should only be used if a Ninja-based build does not work.

With the run argument, a run dependency is registered in addition to a build dependency.

With the testing argument, a test-target is added that uses CTest. When running tests the port will be re-configured for testing and re-built.

For more information see Using cmake.

17.13. `compiler`

Possible arguments: (none), env (default, implicit), C++17-lang, C++14-lang, C++11-lang, gcc-C++11-lib, C++11-lib, C++0x, c11, nestedfct, features

Determines which compiler to use based on any given wishes. Use C++17-lang if the port needs a C++17-capable compiler, C++14-lang if the port needs a C++14-capable compiler, C++11-lang if the port needs a C++11-capable compiler, gcc-C++11-lib if the port needs the g++ compiler with a C++11 library, or C++11-lib if the port needs a C++11-ready standard library. If the port needs a compiler understanding C++0X, C11 or nested functions, the corresponding parameters should be used.

Use features to request a list of features supported by the default compiler. After including bsd.port.pre.mk the port can inspect the results using these variables:

COMPILER_TYPE: the default compiler on the system, either gcc or clang
ALT_COMPILER_TYPE: the alternative compiler on the system, either gcc or clang. Only set if two compilers are present in the base system.
COMPILER_VERSION: the first two digits of the version of the default compiler.
ALT_COMPILER_VERSION: the first two digits of the version of the alternative compiler, if present.
CHOSEN_COMPILER_TYPE: the chosen compiler, either gcc or clang
COMPILER_FEATURES: the features supported by the default compiler. It currently lists the C++ library.

17.14. `cpe`

Possible arguments: (none)

Include Common Platform Enumeration (CPE) information in package manifest as a CPE 2.3 formatted string. See the CPE specification for details. To add CPE information to a port, follow these steps:

Search for the official CPE entry for the software product either by using the NVD’s CPE search engine or in the official CPE dictionary (warning, very large XML file). Do not ever make up CPE data.
Add cpe to USES and compare the result of make -V CPE_STR to the CPE dictionary entry. Continue one step at a time until make -V CPE_STR is correct.
If the product name (second field, defaults to PORTNAME) is incorrect, define CPE_PRODUCT.
If the vendor name (first field, defaults to CPE_PRODUCT) is incorrect, define CPE_VENDOR.
If the version field (third field, defaults to PORTVERSION) is incorrect, define CPE_VERSION.
If the update field (fourth field, defaults to empty) is incorrect, define CPE_UPDATE.
If it is still not correct, check Mk/Uses/cpe.mk for additional details, or contact the Ports Security Team <ports-secteam@FreeBSD.org>.
Derive as much as possible of the CPE name from existing variables such as PORTNAME and PORTVERSION. Use variable modifiers to extract the relevant portions from these variables rather than hardcoding the name.
Always run make -V CPE_STR and check the output before committing anything that changes PORTNAME or PORTVERSION or any other variable which is used to derive CPE_STR.

17.15. `cran`

Possible arguments: (none), auto-plist, compiles

Uses the Comprehensive R Archive Network. Specify auto-plist to automatically generate pkg-plist. Specify compiles if the port has code that need to be compiled.

17.16. `desktop-file-utils`

Possible arguments: (none)

Uses update-desktop-database from devel/desktop-file-utils. An extra post-install step will be run without interfering with any post-install steps already in the port Makefile. A line with @desktop-file-utils will be added to the plist. Only use this macro if the port provides a .desktop file which contains a MimeType entry.

17.17. `desthack`

Possible arguments: (none)

Changes the behavior of GNU configure to properly support DESTDIR in case the original software does not.

17.18. `display`

Possible arguments: (none), ARGS

Set up a virtual display environment. If the environment variable DISPLAY is not set, then Xvfb is added as a build dependency, and CONFIGURE_ENV is extended with the port number of the currently running instance of Xvfb. The ARGS parameter defaults to install and controls the phase around which to start and stop the virtual display.

17.19. `dos2unix`

Possible arguments: (none)

The port has files with line endings in DOS format which need to be converted. Several variables can be set to control which files will be converted. The default is to convert all files, including binaries. See Simple Automatic Replacements for examples.

DOS2UNIX_REGEX: match file names based on a regular expression.
DOS2UNIX_FILES: match literal file names.
DOS2UNIX_GLOB: match file names based on a glob pattern.
DOS2UNIX_WRKSRC: the directory from which to start the conversions. Defaults to ${WRKSRC}.

17.20. `drupal`

Possible arguments: 7, module, theme

Automate installation of a port that is a Drupal theme or module. Use with the version of Drupal that the port is expecting. For example, USES=drupal:7,module says that this port creates a Drupal 7 module. A Drupal 7 theme can be specified with USES=drupal:7,theme.

17.21. `ebur128`

Possible arguments: (none), build, lib, run, test

Adds a dependency on audio/ebur128. It allows to transparently depend on the rust or legacy variants by using DEFAULT_VERSIONS in make.conf. For instance, to use the legacy version, use DEFAULT_VERSIONS+=ebur128=legacy

When no arguments are used, the behavior is the same as if the lib argument was provided. The rest of the arguments provide the corresponding category of dependency.

17.22. `eigen`

Possible arguments: 2, 3, build (default), run

Add dependency on math/eigen.

17.23. `elfctl`

Possible arguments: (none)

USES=           elfctl
ELF_FEATURES=	featurelist:path/to/file1 \
		featurelist:path/to/file1 \
		featurelist:path/to/file2

The format of featurelist is described in elfctl(1). The file paths are relative to ${BUILD_WRKSRC}.

17.24. `erlang`

Possible arguments: (none), enc, rebar, rebar3

Adds a build and run time dependency on lang/erlang. Depending on the argument, it adds additional build dependencies. enc adds a dependency on devel/erlang-native-compiler, rebar adds a dependency on devel/rebar and rebar3 adds a dependency on devel/rebar3.

In addition, the following variables are available to the port:

ERL_APP_NAME: Erlang app name as installed in Erlang’s lib dir (minus version)

Add a dependency to the client library of the Firebird database.

17.28. `fonts`

Possible arguments: (none), fc, fontsdir (default), none

Adds a runtime dependency on tools needed to register fonts. Depending on the argument, add a @fc` ${FONTSDIR}` line, @fontsdir` ${FONTSDIR}` line, or no line if the argument is none, to the plist. FONTSDIR defaults to ${PREFIX}/share/fonts/${FONTNAME} and FONTNAME to ${PORTNAME}. Add FONTSDIR to PLIST_SUB and SUB_LIST

17.29. `fortran`

Possible arguments: gcc (default)

Uses the GNU Fortran compiler.

17.30. `fuse`

Possible arguments: 2 (default), 3

The port will depend on the FUSE library and handle the dependency on the kernel module depending on the version of FreeBSD.

17.31. `gem`

Possible arguments: (none), noautoplist

Handle building with RubyGems. If noautoplist is used, the packing list is not generated automatically.

See Using GNOME for more information.

17.39. `go`

Ports should not be created for Go libs, see Go Libraries for more information.

Possible arguments: (none), N.NN, N.NN-devel, modules, no_targets, run

Sets default values and targets used to build Go software. A build dependency on the Go compiler port is added, port maintainers can set version required. By default the build is performed in GOPATH mode. If Go software uses modules, the modules-aware mode can be switched on with modules argument. no_targets will setup build environment like GO_ENV, GO_BUILDFLAGS but skip creating extract and build targets. run will also add a run dependency on the Go compiler port.

The build process is controlled by several variables:

GO_MODULE: The name of the application module as specified by the module directive in go.mod. In most cases, this is the only required variable for ports that use Go modules.
GO_PKGNAME: The name of the Go package when building in GOPATH mode. This is the directory that will be created in ${GOPATH}/src. If not set explicitly and GH_SUBDIR or GL_SUBDIR is present, GO_PKGNAME will be inferred from it. It is not needed when building in modules-aware mode.
GO_TARGET: The packages to build. The default value is ${GO_PKGNAME}. GO_TARGET can also be a tuple in the form package:path where path can be either a simple filename or a full path starting with ${PREFIX}.
GO_TESTTARGET: The packages to test. The default value is ./… (the current package and all subpackages).
CGO_CFLAGS: Additional CFLAGS values to be passed to the C compiler by go.
CGO_LDFLAGS: Additional LDFLAGS values to be passed to the C compiler by go.
GO_BUILDFLAGS: Additional build arguments to be passed to go build.
GO_TESTFLAGS: Additional build arguments to be passed to go test.

See Building Go Applications for usage examples.

17.40. `gperf`

Possible arguments: (none)

Add a buildtime dependency on devel/gperf if gperf is not present in the base system.

17.41. `grantlee`

Possible arguments: 5, selfbuild

Handle dependency on Grantlee. Specify 5 to depend on the Qt5 based version, devel/grantlee5. selfbuild is used internally by devel/grantlee5 to get their versions numbers.

17.42. `groff`

Possible arguments: build, run, both

Registers a dependency on textproc/groff if not present in the base system.

17.43. `gssapi`

Possible arguments: (none), base (default), heimdal, mit, flags, bootstrap

Handle dependencies needed by consumers of the GSS-API. Only libraries that provide the Kerberos mechanism are available. By default, or set to base, the GSS-API library from the base system is used. Can also be set to heimdal to use security/heimdal, or mit to use security/krb5.

When the local Kerberos installation is not in LOCALBASE, set HEIMDAL_HOME (for heimdal) or KRB5_HOME (for krb5) to the location of the Kerberos installation.

These variables are exported for the ports to use:

GSSAPIBASEDIR
GSSAPICPPFLAGS
GSSAPIINCDIR
GSSAPILDFLAGS
GSSAPILIBDIR
GSSAPILIBS
GSSAPI_CONFIGURE_ARGS

The flags option can be given alongside base, heimdal, or mit to automatically add GSSAPICPPFLAGS, GSSAPILDFLAGS, and GSSAPILIBS to CFLAGS, LDFLAGS, and LDADD, respectively. For example, use base,flags.

The bootstrap option is a special prefix only for use by security/krb5 and security/heimdal. For example, use bootstrap,mit.

Example 122. Typical Use

OPTIONS_SINGLE=	GSSAPI
OPTIONS_SINGLE_GSSAPI=	GSSAPI_BASE GSSAPI_HEIMDAL GSSAPI_MIT GSSAPI_NONE

GSSAPI_BASE_USES=	gssapi

17.45. `guile`

Possible arguments: (none), X.Y, flavors, build, run, alias, conflicts

Adds a dependency on Guile. By default this is a library dependency on the appropriate libguile*.so, unless overridden by the build and/or run option. The alias option configures BINARY_ALIAS appropriately (see Use BINARY_ALIAS).

The default version is set by the usual DEFAULT_VERSIONS mechanism; if the default version is not one of the listed versions, then the latest available listed version is used.

Applications using Guile are normally built for only a single Guile version. However, extension or library modules should use the flavors option to build with multiple flavors.

For more information see Using Guile.

17.46. `horde`

Possible arguments: (none)

Add buildtime and runtime dependencies on devel/pear-channel-horde. Other Horde dependencies can be added with USE_HORDE_BUILD and USE_HORDE_RUN. See Horde Modules for more information.

17.47. `iconv`

Possible arguments: (none), lib, build, patch, translit, wchar_t

Uses iconv functions, either from the port converters/libiconv as a build-time and run-time dependency, or from the base system. By default, with no arguments or with the lib argument, implies iconv with build-time and run-time dependencies. build implies a build-time dependency, and patch implies a patch-time dependency. If the port uses the WCHAR_T or //TRANSLIT iconv extensions, add the relevant arguments so that the correct iconv is used. For more information see Using iconv.

17.48. `imake`

Possible arguments: (none), env, notall, noman

Add devel/imake as a build-time dependency and run xmkmf -a during the configure stage. If the env argument is given, the configure target is not set. If the -a flag is a problem for the port, add the notall argument. If xmkmf does not generate a install.man target, add the noman argument.

17.49. `kde`

Possible arguments: 5

Add dependency on KDE components. See Using KDE for more information.

17.50. `kmod`

Possible arguments: (none), debug

Fills in the boilerplate for kernel module ports, currently:

Add kld to CATEGORIES.
Set SSP_UNSAFE.
Set IGNORE if the kernel sources are not found in SRC_BASE.
Define KMODDIR to /boot/modules by default, add it to PLIST_SUB and MAKE_ENV, and create it upon installation. If KMODDIR is set to /boot/kernel, it will be rewritten to /boot/modules. This prevents breaking packages when upgrading the kernel due to /boot/kernel being renamed to /boot/kernel.old in the process.
Handle cross-referencing kernel modules upon installation and deinstallation, using @kld.
If the debug argument is given, the port can install a debug version of the module into KERN_DEBUGDIR/KMODDIR. By default, KERN_DEBUGDIR is copied from DEBUGDIR and set to /usr/lib/debug. The framework will take care of creating and removing any required directories.

17.51. `ldap`

Possible arguments: (none), <version>, client, server

Registers a dependency on net/openldap. It uses the specific <version> (without the dot notation) if set. Otherwise it tries to find the currently installed version. If necessary it falls back to the default version found in bsd.default-versions.mk. client specifies a runtime dependency on the client library. This is also the default. server specifies a runtime dependency on the server.

The following variables can be accessed by the port:

IGNORE_WITH_OPENLDAP: This variable can be defined if the ports does not support one or more versions of OpenLDAP.
WITH_OPENLDAP_VER: User defined variable to set OpenLDAP version.
OPENLDAP_VER: Detected OpenLDAP version.

17.52. `lha`

Possible arguments: (none)

Set EXTRACT_SUFX to .lzh

17.53. `libarchive`

Possible arguments: (none)

Registers a dependency on archivers/libarchive. Any ports depending on libarchive must include USES=libarchive.

17.54. `libedit`

Possible arguments: (none)

Registers a dependency on devel/libedit. Any ports depending on libedit must include USES=libedit.

17.55. `libtool`

Possible arguments: (none), keepla, build

Patches libtool scripts. This must be added to all ports that use libtool. The keepla argument can be used to keep .la files. Some ports do not ship with their own copy of libtool and need a build time dependency on devel/libtool, use the :build argument to add such dependency.

17.56. `linux`

Possible arguments: c6, c7

Ports Linux compatibility framework. Specify c6 to depend on CentOS 6 packages. Specify c7 to depend on CentOS 7 packages. The available packages are:

allegro
alsa-plugins-oss
alsa-plugins-pulseaudio
alsalib
atk

17.57. `llvm`

Possible arguments: (none), XY, min=XY, max=XY, build, run, lib

Adds a dependency on LLVM. By default this is a build dependency unless overridden by the run or lib options. The default version is the one set in LLVM_DEFAULT. A specific version can be specified as well. The minimum and maximum versions can be specified with the min and max parameters respectively. The ports framework export the following variables to the port:

LLVM_VERSION: Version chosen from the arguments to llvm.mk
LLVM_PORT: Chosen llvm port
LLVM_CONFIG: llvm-config of the chosen port
LLVM_LIBLLVM: libLLVM.so of the chosen port
LLVM_PREFIX: Installation prefix of the chosen port

17.58. `localbase`

Possible arguments: (none), ldflags

Ensures that libraries from dependencies in LOCALBASE are used instead of the ones from the base system. Specify ldflags to add -L${LOCALBASE}/lib to LDFLAGS instead of LIBS. Ports that depend on libraries that are also present in the base system should use this. It is also used internally by a few other USES.

17.59. `lua`

Possible arguments: (none), XY, XY+, -XY, XY-ZA, module, flavors, build, run, env

Adds a dependency on Lua. By default this is a library dependency, unless overridden by the build and/or run option. The env option prevents the addition of any dependency, while still defining all the usual variables.

The default version is set by the usual DEFAULT_VERSIONS mechanism, unless a version or range of versions is specified as an argument, for example, 51 or 51-54.

Applications using Lua are normally built for only a single Lua version. However, library modules intended to be loaded by Lua code should use the module option to build with multiple flavors.

For more information see Using Lua.

17.60. `luajit`

Possible arguments: (none), X

Adds a dependency on luajit runtime. A specific version X can be used. Possible versions are luajit, luajit-devel, luajit-openresty

After including bsd.port.options.mk or bsd.port.pre.mk the port can inspect these variables:

LUAJIT_VER: The selected luajit version
LUAJIT_INCDIR: The path to luajit’s header files
LUAJIT_LUAVER: Which luajit spec version is selected (2.0 for luajit, else 2.1)

For more information see Using Lua.

17.61. `lxqt`

Possible arguments: (none)

Handle dependencies for the LXQt Desktop Environment. Use USE_LXQT to select the components needed for the port. See Using LXQt for more information.

17.62. `magick`

Possible arguments: (none), X, build, nox11, run, test

Add a library dependency on ImageMagick. A specific version X can be used. Possible versions are 6 and 7 (default). nox11 indicates that the -nox11 version of the port is required. build, run and test add build-, run-time and test dependencies on ImageMagick.

17.63. `makeinfo`

Possible arguments: (none)

Add a build-time dependency on makeinfo if it is not present in the base system.

17.64. `makeself`

Possible arguments: (none)

Indicates that the distribution files are makeself archives and sets the appropriate dependencies.

17.65. `mate`

Possible arguments: (none)

Provides an easy way to depend on MATE components. The components should be listed in USE_MATE. The available components are:

autogen
caja
common
controlcenter
desktop
dialogs
docutils
icontheme
intlhack
intltool
libmatekbd
libmateweather
marco
menus
notificationdaemon
panel
pluma
polkit
session
settingsdaemon

The default dependency is build- and run-time, it can be changed with :build or :run. For example:

USES=		mate
USE_MATE=	menus:build intlhack

17.66. `meson`

Possible arguments: (none)

Provide support for Meson based projects. For more information see Using meson.

17.67. `metaport`

Possible arguments: (none)

Sets the following variables to make it easier to create a metaport: MASTER_SITES, DISTFILES, EXTRACT_ONLY, NO_BUILD, NO_INSTALL, NO_MTREE, NO_ARCH.

17.68. `minizip`

Possible arguments: (none), ng

Adds a library dependency on archivers/minizip or archivers/minizip-ng respectively.

17.69. `mysql`

Possible arguments: (none), version, client (default), server, embedded

Provide support for MySQL If no version is given, try to find the current installed version. Fall back to the default version, MySQL-5.6. The possible versions are 55, 55m, 55p, 56, 56p, 56w, 57, 57p, 80, 100m, 101m, and 102m. The m and p suffixes are for the MariaDB and Percona variants of MySQL. server and embedded add a build- and run-time dependency on the MySQL server. When using server or embedded, add client to also add a dependency on libmysqlclient.so. A port can set IGNORE_WITH_MYSQL if some versions are not supported.

The framework sets MYSQL_VER to the detected MySQL version.

17.70. `mono`

Possible arguments: (none), nuget

Adds a dependency on the Mono (currently only C#) framework by setting the appropriate dependencies.

Specify nuget when the port uses nuget packages. NUGET_DEPENDS needs to be set with the names and versions of the nuget packages in the format name=version. An optional package origin can be added using name=version:_origin_.

The helper target, buildnuget, will output the content of the NUGET_DEPENDS based on the provided packages.config.

17.71. `motif`

Possible arguments: (none)

Uses x11-toolkits/open-motif as a library dependency. End users can set WANT_LESSTIF in make.conf to use x11-toolkits/lesstif as dependency instead of x11-toolkits/open-motif. Similarly setting WANT_OPEN_MOTIF_DEVEL in make.conf will add a dependency on x11-toolkits/open-motif-devel

17.72. `ncurses`

Possible arguments: (none), base, port

Uses ncurses, and causes some useful variables to be set.

17.73. `nextcloud`

Possible arguments: (none)

Adds support for Nextcloud applications by adding a run time dependency on www/nextcloud.

17.74. `ninja`

Possible arguments: (none), build, make (default), run

If build or run arguments are specify, it respectively adds a build or run time dependency on devel/ninja. If make or no arguments are provided, use ninja to build the port instead of make. make implies build. If the variable NINJA_DEFAULT is set to samurai, then the dependencies are set on devel/samurai instead.

17.75. `nodejs`

Possible arguments: (none), build, run, current, lts, 10, 14, 16, 17.

Uses nodejs. Adds a dependency on www/node*. If a supported version is specified then run and/or build must be specified too.

17.76. `objc`

Possible arguments: (none)

Add objective C dependencies (compiler, runtime library) if the base system does not support it.

17.77. `octave`

Possible arguments: (none), env

Uses math/octave. env loads only one OCTAVE_VERSION environmental variable.

17.78. `openal`

Possible arguments: al, soft (default), si, alut

Uses OpenAL. The backend can be specified, with the software implementation as the default. The user can specify a preferred backend with WANT_OPENAL. Valid values for this knob are soft (default) and si.

17.79. `pathfix`

Possible arguments: (none)

Look for Makefile.in and configure in PATHFIX_WRKSRC (defaults to WRKSRC) and fix common paths to make sure they respect the FreeBSD hierarchy. For example, it fixes the installation directory of pkgconfig’s .pc files to ${PREFIX}/libdata/pkgconfig. If the port uses `USES=autoreconf, Makefile.am will be added to PATHFIX_MAKEFILEIN automatically.

If the port USES=cmake it will look for CMakeLists.txt in PATHFIX_WRKSRC. If needed, that default filename can be changed with PATHFIX_CMAKELISTSTXT.

17.80. `pear`

Possible arguments: env

Adds a dependency on devel/pear. It will setup default behavior for software using the PHP Extension and Application Repository. Using the env arguments only sets up the PEAR environment variables. See PEAR Modules for more information.

17.81. `perl5`

Possible arguments: (none)

Depends on Perl. The configuration is done using USE_PERL5.

USE_PERL5 can contain the phases in which to use Perl, can be extract, patch, build, run, or test.

USE_PERL5 can also contain configure, modbuild, or modbuildtiny when Makefile.PL, Build.PL, or Module::Build::Tiny’s flavor of Build.PL is required.

USE_PERL5 defaults to build run. When using configure, modbuild, or modbuildtiny, build and run are implied.

See Using Perl for more information.

17.82. `pgsql`

Possible arguments: (none), X.Y, X.Y+, X.Y-, X.Y-Z.A

Provide support for PostgreSQL. Port maintainer can set version required. Minimum and maximum versions or a range can be specified; for example, 9.0-, 8.4+, 8.4-9.2.

By default, the added dependency will be the client, but if the port requires additional components, this can be done using WANT_PGSQL=component[:target]; for example, WANT_PGSQL=server:configure pltcl plperl. The available components are:

client
contrib
docs
pgtcl
plperl
plpython
pltcl
server

17.83. `php`

Possible arguments: (none), phpize, ext, zend, build, cli, cgi, mod, web, embed, pecl, flavors, noflavors

Provide support for PHP. Add a runtime dependency on the default PHP version, lang/php81.

phpize: Use to build a PHP extension. Enables flavors.
ext: Use to build, install and register a PHP extension. Enables flavors.
zend: Use to build, install and register a Zend extension. Enables flavors.
build: Set PHP also as a build-time dependency.
cli: Needs the CLI version of PHP.
cgi: Needs the CGI version of PHP.
mod: Needs the Apache module for PHP.
web: Needs the Apache module or the CGI version of PHP.
embed: Needs the embedded library version of PHP.
pecl: Provide defaults for fetching PHP extensions from the PECL repository. Enables flavors.
flavors: Enable automatic PHP flavors generation. Flavors will be generated for all PHP versions, except the ones present in IGNORE_WITH_PHP.
noflavors: Disable automatic PHP flavors generation. Must only be used with extensions provided by PHP itself.

Variables are used to specify which PHP modules are required, as well as which version of PHP are supported.

USE_PHP: The list of required PHP extensions at run-time. Add :build to the extension name to add a build-time dependency. Example: pcre xml:build gettext

IGNORE_WITH_PHP: The port does not work with PHP of the given version. For possible values look at the content of _ALL_PHP_VERSIONS in Mk/Uses/php.mk.

When building a PHP or Zend extension with :ext or :zend, these variables can be set:

PHP_MODNAME

The name of the PHP or Zend extension. Default value is ${PORTNAME}.

PHP_HEADER_DIRS

A list of subdirectories from which to install header files. The framework will always install the header files that are present in the same directory as the extension.

PHP_MOD_PRIO

The priority at which to load the extension. It is a number between 00 and 99.

For extensions that do not depend on any extension, the priority is automatically set to 20, for extensions that depend on another extension, the priority is automatically set to 30. Some extensions may need to be loaded before every other extension, for example www/php56-opcache. Some may need to be loaded after an extension with a priority of 30. In that case, add PHP_MOD_PRIO=XX in the port’s Makefile. For example:

USES=		php:ext
USE_PHP=	wddx
PHP_MOD_PRIO=	40

These variables are available to use in PKGNAMEPREFIX or PKGNAMESUFFIX:

PHP_PKGNAMEPREFIX: Contains php_XY_- where XY is the current flavor’s PHP version. Use with PHP extensions and modules.
PHP_PKGNAMESUFFIX: Contains -php_XY_ where XY is the current flavor’s PHP version. Use with PHP applications.
PECL_PKGNAMEPREFIX: Contains php_XY_-pecl- where XY is the current flavor’s PHP version. Use with PECL modules.

With flavors, all PHP extensions, PECL extensions, PEAR modules must have a different package name, so they must all use one of these three variables in their PKGNAMEPREFIX or PKGNAMESUFFIX.

17.84. `pkgconfig`

Possible arguments: (none), build (default), run, both

Uses devel/pkgconf. With no arguments or with the build argument, it implies pkg-config as a build-time dependency. run implies a run-time dependency and both implies both run-time and build-time dependencies.

17.85. `pure`

Possible arguments: (none), ffi

Uses lang/pure. Largely used for building related pure ports. With the ffi argument, it implies devel/pure-ffi as a run-time dependency.

17.86. `pyqt`

Possible arguments: (none), 4, 5

Uses PyQt. If the port is part of PyQT itself, set PYQT_DIST. Use USE_PYQT to select the components the port needs. The available components are:

core
dbus
dbussupport
demo
designer
designerplugin
doc
gui
multimedia
network
opengl
qscintilla2
sip
sql
svg
test
webkit

assistant
declarative
help
phonon
script
scripttools

These components are only available with PyQT5:

multimediawidgets
printsupport
qml
serialport
webkitwidgets
widgets

The default dependency for each component is build- and run-time, to select only build or run, add _build or _run to the component name. For example:

USES=		pyqt
USE_PYQT=	core doc_build designer_run

17.87. `pytest`

Possible arguments: (none), 4

Introduces a new dependency on devel/pytest. It defines a do-test target which will run the tests properly. Use the argument to depend on a specific devel/pytest version. For ports using devel/pytest consider using this instead of a specific do-test target. The framework exposes the following variables to the port:

PYTEST_ARGS: Additional arguments to pytest (defaults to empty).
PYTEST_IGNORED_TESTS: lists of pytest -k patterns of tests to ignore (defaults to empty). For tests which are not expected to pass, such as ones requiring a database access.
PYTEST_BROKEN_TESTS: lists of pytest -k patterns of tests to ignore (defaults to empty). For broken tests which require fixing.

In addition the following variables may be set by the user:

PYTEST_ENABLE_IGNORED_TESTS: Enable tests which are otherwise ignored by PYTEST_IGNORED_TESTS.
PYTEST_ENABLE_BROKEN_TESTS: Enable tests which are otherwise ignored by PYTEST_BROKEN_TESTS.
PYTEST_ENABLE_ALL_TESTS: Enable tests which are otherwise ignored by PYTEST_IGNORED_TESTS and PYTEST_BROKEN_TESTS.

17.88. `python`

Possible arguments: (none), X.Y, X.Y+, -X.Y, X.Y-Z.A, patch, build, run, test

Uses Python. A supported version or version range can be specified. If Python is only needed at build time, run time or for the tests, it can be set as a build, run or test dependency with build, run, or test. If Python is also needed during the patch phase, use patch. See Using Python for more information.

USES=python:env can be used when the variables exported by the framework are needed but a dependency on Python is not. It can happen when using with USES=shebangfix, and the goal is only to fix the shebangs but not add a dependency on Python.

17.89. `qmail`

Possible arguments: (none), build, run, both, vars

Uses mail/qmail. With the build argument, it implies qmail as a build-time dependency. run implies a run-time dependency. Using no argument or the both argument implies both run-time and build-time dependencies. vars will only set QMAIL variables for the port to use.

17.90. `qmake`

Possible arguments: (none), norecursive, outsource, no_env, no_configure

Uses QMake for configuring. For more information see Using qmake.

17.91. `qt`

Possible arguments: 5, 6, no_env

Add dependency on Qt components. no_env is passed directly to USES= qmake. See Using Qt for more information.

17.92. `qt-dist`

Possible arguments: (none) or 5 and (none) or 6 and (none) or one of 3d, 5compat, base, charts, connectivity, datavis3d, declarative, doc languageserver, gamepad, graphicaleffects, imageformats, locat ion, lottie, multimedia, networkauth, positioning, quick3d, quickcontrols2, quickcontrols, quicktimeline, remoteobjects, script, scxml `, `sensors, serialbus, serialport, shadertools, speech, svg, tools, translations, virtualkeyboard, wayland, webchannel, webengine, webglplugin, websockets, webview, x11extras, xmlpatterns.

Provides support for building Qt 5 and Qt 6 components. It takes care of setting up the appropriate configuration environment for the port to build.

Example 123. Building Qt 5 Components

The port is Qt 5’s networkauth component, which is part of the networkauth distribution file.

PORTNAME=	networkauth
DISTVERSION=	${QT5_VERSION}

USES=		qt-dist:5

Example 124. Building Qt 6 Components

The port is Qt 6’s websockets component, which is part of the websockets distribution file.

PORTNAME=       websockets
PORTVERSION=    ${QT6_VERSION}

USES=           qt-dist:6

If PORTNAME does not match the component name, it can be passed as an argument to qt-dist.

Example 125. Building Qt 5 Components with Different Names

The port is Qt 5’s gui component, which is part of the base distribution file.

PORTNAME=	gui
DISTVERSION=	${QT5_VERSION}

USES=		qt-dist:5,base

17.93. `readline`

Possible arguments: (none), port

Uses readline as a library dependency, and sets CPPFLAGS and LDFLAGS as necessary. If the port argument is used or if readline is not present in the base system, add a dependency on devel/readline

17.94. `ruby`

Possible arguments: (none), build, extconf, run, setup

Provide support for Ruby related ports. (none) without arguments adds runtime dependency on lang/ruby. build adds a dependency on lang/ruby at build time. extconf states that the port uses extconf.rb to configure. run adds a dependency on lang/ruby at run time. This is also the default. setup states that the port uses setup.rb to configure and build.

The user may have the following variables defined:

RUBY_VER: Alternative short version of ruby in the form of `x.y'.
RUBY_DEFAULT_VER: Set to (e.g.) 2.7 to use ruby27 as the default version.
RUBY_ARCH: Set the architecture name (e.g. i386-freebsd7).

The following variables are exported to be used by the port:

RUBY: Set to full path of ruby. If set, the values of the following variables are automatically obtained from the ruby executable: RUBY_ARCH, RUBY_ARCHLIBDIR, RUBY_LIBDIR, RUBY_SITEARCHLIBDIR, RUBY_SITELIBDIR, RUBY_VER and RUBY_VERSION
RUBY_VER: Set to the alternative short version of ruby in the form of `x.y'.
RUBY_EXTCONF: Set to the alternative name of extconf.rb (default: extconf.rb).
RUBY_EXTCONF_SUBDIRS: Set to list of subdirectories, if multiple modules are included.
RUBY_SETUP: Set to the alternative name of setup.rb (default: setup.rb).

17.95. `samba`

Possible arguments: build, env, lib, run

Handle dependency on Samba. env will not add any dependency and only set up the variables. build and run will add build-time and run-time dependency on smbd. lib will add a dependency on libsmbclient.so. The variables that are exported are:

SAMBA_PORT: The origin of the default Samba port.
SAMBA_INCLUDEDIR: The location of the Samba header files.
SAMBA_LIBS: The directory where the Samba shared libraries are available.
SAMBA_LDB_PORT: The origin of the ldb port used by the selected Samba version (e.g., databases/ldb28). It should be used if a port needs to depend on the same ldb version as the selected Samba version.

17.96. `scons`

Possible arguments: (none)

Provide support for the use of devel/scons. See Using scons for more information.

17.97. `shared-mime-info`

Possible arguments: (none)

Uses update-mime-database from misc/shared-mime-info. This uses will automatically add a post-install step in such a way that the port itself still can specify there own post-install step if needed. It also add an @shared-mime-info entry to the plist.

17.98. `shebangfix`

Possible arguments: (none)

A lot of software uses incorrect locations for script interpreters, most notably /usr/bin/perl and /bin/bash. The shebangfix macro fixes shebang lines in scripts listed in SHEBANG_REGEX, SHEBANG_GLOB, or SHEBANG_FILES.

SHEBANG_REGEX: Contains one extended regular expressions, and is used with the -iregex argument of find(1). See USESshebangfix with SHEBANG_REGEX.
SHEBANG_GLOB: Contains a list of patterns used with the -name argument of find(1). See USESshebangfix with SHEBANG_GLOB.
SHEBANG_FILES: Contains a list of files or sh(1) globs. The shebangfix macro is run from ${WRKSRC}, so SHEBANG_FILES can contain paths that are relative to ${WRKSRC}. It can also deal with absolute paths if files outside of ${WRKSRC} require patching. See USESshebangfix with SHEBANG_FILES.

Currently Bash, Java, Ksh, Lua, Perl, PHP, Python, Ruby, Tcl, and Tk are supported by default.

There are three configuration variables:

SHEBANG_LANG

The list of supported interpreters.

_interp__CMD

The path to the command interpreter on FreeBSD. The default value is ${LOCALBASE}/bin/interp.

_interp__OLD_CMD

The list of wrong invocations of interpreters. These are typically obsolete paths, or paths used on other operating systems that are incorrect on FreeBSD. They will be replaced by the correct path in _interp__CMD.

These will always be part of interp__OLD_CMD: "/usr/bin/env _interp" /bin/interp /usr/bin/interp /usr/local/bin/interp.

_interp__OLD_CMD contain multiple values. Any entry with spaces must be quoted. See Specifying all the Paths When Adding an Interpreter to USESshebangfix.

The fixing of shebangs is done during the patch phase. If scripts are created with incorrect shebangs during the build phase, the build process (for example, the configure script, or the Makefiles) must be patched or given the right path (for example, with CONFIGURE_ENV, CONFIGURE_ARGS, MAKE_ENV, or MAKE_ARGS) to generate the right shebangs.

Correct paths for supported interpreters are available in _interp__CMD.

When used with USES=python, and the aim is only to fix the shebangs but a dependency on Python itself is not wanted, use USES=python:env instead.

Example 126. Adding Another Interpreter to USES=shebangfix

To add another interpreter, set SHEBANG_LANG. For example:

SHEBANG_LANG=	lua

Example 127. Specifying all the Paths When Adding an Interpreter to USES=shebangfix

If it was not already defined, and there were no default values for _interpOLD_CMD and _interpCMD the Ksh entry could be defined as:

SHEBANG_LANG=	ksh
ksh_OLD_CMD=	"/usr/bin/env ksh" /bin/ksh /usr/bin/ksh
ksh_CMD=	${LOCALBASE}/bin/ksh

Example 128. Adding a Strange Location for an Interpreter

Some software uses strange locations for an interpreter. For example, an application might expect Python to be located in /opt/bin/python2.7. The strange path to be replaced can be declared in the port Makefile:

python_OLD_CMD=	/opt/bin/python2.7

Example 129. USES=shebangfix with SHEBANG_REGEX

To fix all the files in ${WRKSRC}/scripts ending in .pl, .sh, or .cgi do:

USES=	shebangfix
SHEBANG_REGEX=	./scripts/.*\.(sh|pl|cgi)

SHEBANG_REGEX is used by running find -E, which uses modern regular expressions also known as extended regular expressions. See re_format(7) for more information.

Example 130. USES=shebangfix with SHEBANG_GLOB

To fix all the files in ${WRKSRC} ending in .pl or .sh, do:

USES=	shebangfix
SHEBANG_GLOB=	*.sh *.pl

Example 131. USES=shebangfix with SHEBANG_FILES

To fix the files script/foobar.pl and script/*.sh in ${WRKSRC}, do:

USES=	shebangfix
SHEBANG_FILES=	scripts/foobar.pl scripts/*.sh

17.99. `sqlite`

Possible arguments: (none), 2, 3

Add a dependency on SQLite. The default version used is 3, but version 2 is also possible using the :2 modifier.

17.100. `ssl`

Possible arguments: (none), build, run

Provide support for OpenSSL. A build- or run-time only dependency can be specified using build or run. These variables are available for the port’s use, they are also added to MAKE_ENV:

OPENSSLBASE: Path to the OpenSSL installation base.
OPENSSLDIR: Path to OpenSSL’s configuration files.
OPENSSLLIB: Path to the OpenSSL libraries.
OPENSSLINC: Path to the OpenSSL includes.
OPENSSLRPATH: If defined, the path the linker needs to use to find the OpenSSL libraries.

If a port does not build with an OpenSSL flavor, set the BROKEN_SSL variable, and possibly the BROKEN_SSL_REASON__flavor_:

BROKEN_SSL=	libressl
BROKEN_SSL_REASON_libressl=	needs features only available in OpenSSL

17.101. `tar`

Possible arguments: (none), Z, bz2, bzip2, lzma, tbz, tbz2, tgz, txz, xz, zst, zstd

Set EXTRACT_SUFX to .tar, .tar.Z, .tar.bz2, .tar.bz2, .tar.lzma, .tbz, .tbz2, .tgz, .txz, .tar.xz, .tar.zst or .tar.zstd respectively.

17.102. `tcl`

Possible arguments: version, wrapper, build, run, tea

Add a dependency on Tcl. A specific version can be requested using version. The version can be empty, one or more exact version numbers (currently 84, 85, or 86), or a minimal version number (currently 84+, 85+ or 86+). To only request a non version specific wrapper, use wrapper. A build- or run-time only dependency can be specified using build or run. To build the port using the Tcl Extension Architecture, use tea. After including bsd.port.pre.mk the port can inspect the results using these variables:

TCL_VER: chosen major.minor version of Tcl
TCLSH: full path of the Tcl interpreter
TCL_LIBDIR: path of the Tcl libraries
TCL_INCLUDEDIR: path of the Tcl C header files
TCL_PKG_LIB_PREFIX: Library prefix, as per TIP595

17.104. `tex`

Possible arguments: (none)

Provide support for tex. Loads all the default variables for TEX related ports and does not add any dependency on any ports.

Variables are used to specify which TEX modules are required.

USE_TEX: The list of required TEX extensions at run-time. Add :build to the extension name to add a build-time dependency, :run to add runtime dependency, :test for test time dependency, :extract for extract time dependency. Example: base texmf:build source:run

Small wrapper when using both Tcl and Tk. The same variables are returned as when using Tcl.

17.106. `uidfix`

Possible arguments: (none)

Changes some default behavior (mostly variables) of the build system to allow installing this port as a normal user. Try this in the port before using USES=fakeroot or patching.

17.107. `uniquefiles`

Possible arguments: (none), dirs

228001	41418	November 29, 1998	2.2-STABLE after 2.2.8-RELEASE

Note that 2.2-STABLE sometimes identifies itself as "2.2.5-STABLE" after the 2.2.5-RELEASE. The pattern used to be year followed by the month, but the community decided to change it to a more straightforward major/minor system starting from 2.2. This is because the parallel development on several branches made it infeasible to classify the releases merely by their real release dates. Do not worry about old -CURRENTs; they are listed here just for reference.
