[[staging]] == Staging [.filename]#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 crossref:testing[porting-prefix,`PREFIX` and `DESTDIR`]). [NOTE] ==== No port _really_ needs to be root. It can mostly be avoided by using crossref:uses[uses-uidfix,`USES=uidfix`]. If the port still runs commands like man:chown[8], man:chgrp[1], or forces owner or group with man:install[1] then use crossref:uses[uses-fakeroot,`USES=fakeroot`] to fake those calls. Some patching of the port's [.filename]#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 man: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 man:mtree[8] extraction, add this line: [.programlisting] .... NO_MTREE= yes .... [TIP] ==== Metaports should use <>. 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`, `MANPREFIX`, `DOCSDIR`, and so on. Directories should be created as part of the `post-install` target. Avoid using absolute paths whenever possible. [TIP] ==== Ports that install kernel modules must prepend `STAGEDIR` to their destination, by default [.filename]#/boot/modules#. ==== [[staging-symlink]] === Handling Symbolic Links When creating a symbolic link, relative ones are strongly recommended. Use `${RLN}` to create relative symbolic links. It uses man:install[1] under the hood to automatically figure out the relative link to create. [[staging-ex1]] .Create Relative Symbolic Links Automatically [example] ==== `${RLN}` uses man:install[1]'s relative symbolic feature which frees the porter of computing the relative path. [.programlisting] .... ${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 ....

[[bundled-libs-why-bad]] === 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 https://fedoraproject.org/wiki/Packaging:No_Bundled_Libraries[Fedora] and https://wiki.gentoo.org/wiki/Why_not_bundle_dependencies[Gentoo] wikis, both licensed under the https://creativecommons.org/licenses/by-sa/3.0/[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. [[bundled-libs-practices]] === 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. [NOTE] ==== 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 [.filename]#Makefile#. This will tell man:pkg[8] to not compute provided libraries. Always ask the {portmgr} before adding this to a port. ==== [[porting-shlibs]] == Shared Libraries If the port installs one or more shared libraries, define a `USE_LDCONFIG` make variable, which will instruct a [.filename]#bsd.port.mk# to run `${LDCONFIG} -m` on the directory where the new library is installed (usually [.filename]#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 [.filename]#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. [.programlisting] .... 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 [.filename]#PREFIX/lib/foo# and [.filename]#PREFIX/lib/bar# use this in [.filename]#Makefile#: [.programlisting] .... 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 package:lang/mosml[] for an example), or through a shell-wrapper which sets `LD_LIBRARY_PATH` before invoking the binary, like package:www/seamonkey[] does. When installing 32-bit libraries on a 64-bit system, use `USE_LDCONFIG32` instead. If the software uses <>, and specifically `libtool`, add crossref:uses[uses-libtool,`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. [[porting-restrictions]] == 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. [IMPORTANT] ==== 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}. ==== In situations like this, the variables described in the next sections can be set. [[porting-restrictions-no_package]] === `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. [[porting-restrictions-no_cdrom]] === `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. [[porting-restrictions-nofetchfiles]] === `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. [[porting-restrictions-restricted]] === `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. [[porting-restrictions-restricted_files]] === `RESTRICTED_FILES` When `RESTRICTED` or `NO_CDROM` is set, this variable defaults to `${DISTFILES} ${PATCHFILES}`, otherwise it is empty. If only some of the distribution files are restricted, then set this variable to list them. [[porting-restrictions-legal_text]] === `LEGAL_TEXT` If the port has legal concerns not addressed by the above variables, set `LEGAL_TEXT` to a string explaining the concern. For example, if special permission was obtained for FreeBSD to redistribute the binary, this variable must indicate so. [[porting-restrictions-legal]] === [.filename]#/usr/ports/LEGAL# and `LEGAL` A port which sets any of the above variables must also be added to [.filename]#/usr/ports/LEGAL#. The first column is a glob which matches the restricted distfiles. The second column is the port's origin. The third column is the output of `make -VLEGAL`. [[porting-restrictions-examples]] === Examples The preferred way to state "the distfiles for this port must be fetched manually" is as follows: [.programlisting] .... .if !exists(${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 [.filename]#bsd.port.pre.mk#. [[building]] == Building Mechanisms [[parallel-builds]] === 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 man: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. [IMPORTANT] ==== When setting `MAKE_JOBS_UNSAFE`, it is very important to explain either with a comment in the [.filename]#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. ==== [[using-make]] === `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 [.filename]#Makefile#. Only use `MAKE_CMD` within the application [.filename]##Makefile##s in `WRKSRC` to call the `make` implementation expected by the ported software. If the port is an X application that uses imake to create [.filename]##Makefile##s from [.filename]##Imakefile##s, set `USES= imake`. See the crossref:uses[uses-imake,`USES=imake`] section of crossref:uses[uses,Using `USES` Macros] for more details. If the port's source [.filename]#Makefile# has something other than `all` as the main build target, set `ALL_TARGET` accordingly. The same goes for `install` and `INSTALL_TARGET`. [[using-configure]] === `configure` Script If the port uses the `configure` script to generate [.filename]#Makefile# from [.filename]#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=${MANPREFIX}/man --build=${CONFIGURE_TARGET}`), set those extra arguments in `CONFIGURE_ARGS`. Extra environment variables can be passed using `CONFIGURE_ENV`. [[using-configure-variables]] .Variables for Ports That Use `configure` [cols="1,1", frame="none", options="header"] |=== | 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}`. |=== [[using-cmake]] === Using `cmake` For ports that use CMake, define `USES= cmake`. [[using-cmake-variables]] .Variables for Ports That Use `cmake` [cols="1,1", frame="none", options="header"] |=== | 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_OFF` |For each entry in `CMAKE_OFF`, a disabled boolean value is added to `CMAKE_ARGS`. See <>. |`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 `${WRKSRC}`. |`CONFIGURE_ENV` |Additional environment variables to be set for the `cmake` binary. |=== [[using-cmake-user-variables]] .Variables the Users Can Define for `cmake` Builds [cols="1,1", frame="none", options="header"] |=== | Variable | Means |`CMAKE_NOCOLOR` |Disables color build output. Default not set, unless `BATCH` or `PACKAGE_BUILDING` are set. |=== CMake supports these build profiles: `Debug`, `Release`, `RelWithDebInfo` and `MinSizeRel`. `Debug` and `Release` profiles respect system `\*FLAGS`, `RelWithDebInfo` and `MinSizeRel` will set `CFLAGS` to `-O2 -g` and `-Os -DNDEBUG` correspondingly. The lower-cased value of `CMAKE_BUILD_TYPE` is exported to `PLIST_SUB` and must be used if the port installs [.filename]#*.cmake# depending on the build type (see package:devel/kf5-kcrash[] for an example). Please note that some projects may define their own build profiles and/or force particular build type by setting `CMAKE_BUILD_TYPE` in [.filename]#CMakeLists.txt#. To make a port for such a project respect `CFLAGS` and `WITH_DEBUG`, the `CMAKE_BUILD_TYPE` definitions must be removed from those files. Most CMake-based projects support an out-of-source method of building. The out-of-source build for a port is the default setting. An in-source build can be requested by using the `:insource` suffix. With out-of-source builds, `CONFIGURE_WRKSRC`, `BUILD_WRKSRC` and `INSTALL_WRKSRC` will be set to `${WRKDIR}/.build` and this directory will be used to keep all files generated during configuration and build stages, leaving the source directory intact. [[using-cmake-example]] .`USES= cmake` Example [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. [.programlisting] .... USES= cmake CMAKE_SOURCE_PATH= ${WRKSRC}/subproject .... ==== [[using-cmake-example2]] .`CMAKE_ON` and `CMAKE_OFF` [example] ==== When adding boolean values to `CMAKE_ARGS`, it is easier to use the `CMAKE_ON` and `CMAKE_OFF` variables instead. This: [.programlisting] .... CMAKE_ON= VAR1 VAR2 CMAKE_OFF= VAR3 .... Is equivalent to: [.programlisting] .... CMAKE_ARGS= -DVAR1:BOOL=TRUE -DVAR2:BOOL=TRUE -DVAR3:BOOL=FALSE .... [IMPORTANT] ====== This is only for the default values off `CMAKE_ARGS`. The helpers described in crossref:makefiles[options-cmake_bool,`OPT_CMAKE_BOOL` and `OPT_CMAKE_BOOL_OFF`] use the same semantics, but for optional values. ====== ==== [[using-scons]] === Using `scons` If the port uses SCons, define `USES=scons`. To make third party [.filename]#SConstruct# respect everything that is passed to SCons in the environment (that is, most importantly, `CC/CXX/CFLAGS/CXXFLAGS`), patch [.filename]#SConstruct# so build `Environment` is constructed like this: [.programlisting] .... env = Environment(**ARGUMENTS) .... It may be then modified with `env.Append` and `env.Replace`. [[using-cargo]] === Building Rust Applications with `cargo` For ports that use Cargo, define `USES=cargo`. [[using-cargo-user-variables]] .Variables the Users Can Define for `cargo` Builds [cols="1,1,1", frame="none", options="header"] |=== | Variable | Default | Description |`CARGO_CRATES` | |List of crates the port depends on. Each entry needs to have a format like `cratename-semver` for example, `libc-0.2.40`. Port maintainers can generate this list from [.filename]#Cargo.lock# using `make cargo-crates`. Manually bumping crate versions is possible but be mindful of transitive dependencies. |`CARGO_FEATURES` | |List of application features to build (space separated list). To deactivate all default features add the special token `--no-default-features` to `CARGO_FEATURES`. Manually passing it to `CARGO_BUILD_ARGS`, `CARGO_INSTALL_ARGS`, and `CARGO_TEST_ARGS` is not needed. |`CARGO_CARGOTOML` |`${WRKSRC}/Cargo.toml` |The path to the [.filename]#Cargo.toml# to use. |`CARGO_CARGOLOCK` |`${WRKSRC}/Cargo.lock` |The path to the [.filename]#Cargo.lock# to use for `make cargo-crates`. It is possible to specify more than one lock file when necessary. |`CARGO_ENV` | |A list of environment variables to pass to Cargo similar to `MAKE_ENV`. |`RUSTFLAGS` | |Flags to pass to the Rust compiler. |`CARGO_CONFIGURE` |`yes` |Use the default `do-configure`. |`CARGO_UPDATE_ARGS` | |Extra arguments to pass to Cargo during the configure phase. Valid arguments can be looked up with `cargo update --help`. |`CARGO_BUILDDEP` |`yes` |Add a build dependency on package:lang/rust[]. |`CARGO_CARGO_BIN` |`${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` |`${WRKDIR}/target` |Location of the cargo output directory. |`CARGO_DIST_SUBDIR` |[.filename]#rust/crates# |Directory relative to `DISTDIR` where the crate distribution files will be stored. |`CARGO_VENDOR_DIR` |`${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 [.filename]#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`. |=== [[cargo-ex1]] .Creating a Port for a Simple Rust Application [example] ==== Creating a Cargo based port is a three stage process. First we need to provide a ports template that fetches the application distribution file: [.programlisting] ....

[...] .... 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. ==== [[cargo-ex2]] .Enabling Additional Application Features [example] ==== Some applications define additional features in their [.filename]#Cargo.toml#. They can be compiled in by setting `CARGO_FEATURES` in the port. Here we enable Tokei's `json` and `yaml` features: [.programlisting] .... CARGO_FEATURES= json yaml .... ==== [[cargo-ex4]] .Encoding Application Features As Port Options [example] ==== An example `[features]` section in [.filename]#Cargo.toml# could look like this: [.programlisting] .... [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: [.programlisting] .... CARGO_FEATURES= --no-default-features OPTIONS_DEFINE= PORTAUDIO PULSEAUDIO PORTAUDIO_VARS= CARGO_FEATURES+=portaudio_backend PULSEAUDIO_VARS= CARGO_FEATURES+=pulseaudio_backend .... ==== [[cargo-ex3]] .Listing Crate Licenses [example] ==== Crates have their own licenses.

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. ==== [[go-ex2]] .Setting Output Binary Name or Installation Path [example] ==== Some ports need to install the resulting binary under a different name or to a path other than the default `${PREFIX}/bin`. This can be done by using `GO_TARGET` tuple syntax, for example: [.programlisting] .... GO_TARGET= ./cmd/ipfs:ipfs-go .... will install `ipfs` binary as `${PREFIX}/bin/ipfs-go` and [.programlisting] .... GO_TARGET= ./dnscrypt-proxy:${PREFIX}/sbin/dnscrypt-proxy .... will install `dnscrypt-proxy` to `${PREFIX}/sbin`. ==== [[using-cabal]] === Building Haskell Applications with `cabal` For ports that use Cabal, build system defines `USES=cabal`.

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. [[cabal-ex2]] .Handling Data Files in a Haskell Port [example] ==== `devel/hs-profiteur` is a Haskell application that generates a single-page HTML with some content. [.programlisting] .... PORTNAME= profiteur [...] USES= cabal USE_CABAL= OneTuple-0.3.1_2 \ QuickCheck-2.14.2 \ [...] .include .... It installs HTML templates under `share/profiteur`, so we need to add `CABAL_WRAPPER_SCRIPTS` knob: [.programlisting] .... [...] USE_CABAL= OneTuple-0.3.1_2 \ QuickCheck-2.14.2 \ [...] CABAL_WRAPPER_SCRIPTS= ${CABAL_EXECUTABLES} .include .... 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: [.programlisting] .... [...] CABAL_WRAPPER_SCRIPTS= ${CABAL_EXECUTABLES} profiteur_DATADIR_VARS= js-jquery .include .... 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. [[cabal-ex3]] .Porting Haskell Applications with VCS Dependencies [example] ==== `net-p2p/cardano-node` is an extremely complex piece of software. In its `cabal.project` there are a lot of blocks like this: [.programlisting] .... [...] 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`: [source,shell] .... % 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: [.programlisting] .... 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: [.programlisting] .... BINARY_ALIAS= git=true .... ==== [[using-autotools]] == Using GNU Autotools If a port needs any of the GNU Autotools software, add `USES=autoreconf`. See crossref:uses[uses-autoreconf,`autoreconf`] for more information. [[using-gettext]] == Using GNU `gettext` [[using-gettext-basic]] === Basic Usage If the port requires `gettext`, set `USES= gettext`, and the port will inherit a dependency on [.filename]#libintl.so# from package:devel/gettext[]. Other values for `gettext` usage are listed in crossref:uses[uses-gettext,`USES=gettext`]. A rather common case is a port using `gettext` and `configure`. Generally, GNU `configure` should be able to locate `gettext` automatically. [.programlisting] .... 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: [.programlisting] .... USES= gettext localbase:ldflags GNU_CONFIGURE= yes .... [[using-gettext-optional]] === 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: [.programlisting] .... GNU_CONFIGURE= yes OPTIONS_DEFINE= NLS OPTIONS_SUB= yes NLS_USES= gettext NLS_CONFIGURE_ENABLE= nls .include .... Or using the older way of using options: [.programlisting] .... GNU_CONFIGURE= yes OPTIONS_DEFINE= NLS .include .if ${PORT_OPTIONS:MNLS} USES+= gettext PLIST_SUB+= NLS="" .else CONFIGURE_ARGS+= --disable-nls PLIST_SUB+= NLS="@comment " .endif .include .... 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 [.filename]#Makefile# part of this task is already provided by the idiom. It is explained in the section on crossref:plist[plist-sub,advanced [.filename]#pkg-plist# practices]. In a nutshell, each occurrence of `%%NLS%%` in [.filename]#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 [.filename]#pkg-plist#. For example: [.programlisting] .... %%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 crossref:plist[plist-dynamic,dynamic packing list generation]. [[using-gettext-catalog-directories]] === Handling Message Catalog Directories There is a point to note about installing message catalog files. The target directories for them, which reside under [.filename]#LOCALBASE/share/locale#, must not be created and removed by a port. The most popular languages have their respective directories listed in [.filename]#PORTSDIR/Templates/BSD.local.dist#. The directories for many other languages are governed by the package:devel/gettext[] port. Consult its [.filename]#pkg-plist# and see whether the port is going to install a message catalog file for a unique language. [[using-perl]] == 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 https://cpan.org/modules/by-module/[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 crossref:uses[uses-perl5,the perl5 USES description]. [[using-perl-variables]] .Read-Only Variables for Ports That Use Perl [cols="1,1", frame="none", options="header"] |=== | Read only variables | Means |`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 crossref:uses[uses-shebangfix,`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`. |=== [NOTE] ==== Ports of Perl modules which do not have an official website must link to `cpan.org` in the WWW line of [.filename]#Makefile#. The preferred URL form is `https://search.cpan.org/dist/Module-Name/` (including the trailing slash). ==== [NOTE] ==== Do not use `${SITE_PERL}` in dependency declarations. Doing so assumes that [.filename]#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. ==== [[use-perl-dependency-example]] .Perl Dependency Example [example] ==== [.programlisting] .... 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 [.filename]#pkg-plist#. For example, [.programlisting] .... lib/perl5/5.14/man/man1/event.1.gz lib/perl5/5.14/man/man3/AnyEvent::I3.3.gz .... can be replaced with [.programlisting] .... %%PERL5_MAN1%%/event.1.gz %%PERL5_MAN3%%/AnyEvent::I3.3.gz .... [NOTE] ==== 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. ==== [[use-perl-ex-build]] .A Port Which Only Requires Perl to Build [example] ==== As the default USE_PERL5 value is build and run, set it to: [.programlisting] .... USES= perl5 USE_PERL5= build .... ==== [[use-perl-ex-patch]] .A Port Which Also Requires Perl to Patch [example] ==== From time to time, using man:sed[1] for patching is not enough. When using man:perl[1] is easier, use: [.programlisting] .... USES= perl5 USE_PERL5= patch build run .... ==== [[use-perl-ex-configure]] .A Perl Module Which Needs `ExtUtils::MakeMaker` to Build [example] ==== Most Perl modules come with a [.filename]#Makefile.PL# configure script. In this case, set: [.programlisting] .... USES= perl5 USE_PERL5= configure .... ==== [[use-perl-ex-modbuild]] .A Perl Module Which Needs `Module::Build` to Build [example] ==== When a Perl module comes with a [.filename]#Build.PL# configure script, it can require Module::Build, in which case, set [.programlisting] .... USES= perl5 USE_PERL5= modbuild .... If it instead requires Module::Build::Tiny, set [.programlisting] .... USES= perl5 USE_PERL5= modbuildtiny .... ==== [[using-x11]] == Using X11 [[x11-variables]] === 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 crossref:uses[uses-xorg,`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 crossref:uses[uses-gl,`gl`] for a full list of available components. For backwards compatibility, the value of `yes` maps to `glu`. [[use-xorg-example]] .`USE_XORG` Example [example] ==== [.programlisting] .... USES= gl xorg USE_GL= glu USE_XORG= xrender xft xkbfile xt xaw .... ==== [[using-xorg-variables]] .Variables for Ports That Use X [cols="1,1", frame="none"] |=== |`USES= imake` |The port uses `imake`. |`XMKMF` |Set to the path of `xmkmf` if not in the `PATH`. Defaults to `xmkmf -a`. |=== [[using-x11-vars]] .Using X11-Related Variables [example] ==== [.programlisting] .... # Use some X11 libraries USES= xorg USE_XORG= x11 xpm .... ==== [[x11-motif]] === Ports That Require Motif If the port requires a Motif library, define `USES= motif` in the [.filename]#Makefile#. Default Motif implementation is package:x11-toolkits/open-motif[]. Users can choose package:x11-toolkits/lesstif[] instead by setting `WANT_LESSTIF` in their [.filename]#make.conf#. Similarly package:x11-toolkits/open-motif-devel[] can be chosen by setting `WANT_OPEN_MOTIF_DEVEL` in [.filename]#make.conf#. `MOTIFLIB` will be set by [.filename]#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 [.filename]#Makefile# or [.filename]#Imakefile#. There are two common cases: * If the port refers to the Motif library as `-lXm` in its [.filename]#Makefile# or [.filename]#Imakefile#, substitute `${MOTIFLIB}` for it. * If the port uses `XmClientLibs` in its [.filename]#Imakefile#, change it to `${MOTIFLIB} ${XTOOLLIB} ${XLIB}`. Note that `MOTIFLIB` (usually) expands to `-L/usr/local/lib -lXm -lXp` or `/usr/local/lib/libXm.a`, so there is no need to add `-L` or `-l` in front. [[x11-fonts]] === X11 Fonts If the port installs fonts for the X Window System, put them in [.filename]#LOCALBASE/lib/X11/fonts/local#. [[x11-fake-display]] === Getting a Fake `DISPLAY` with Xvfb Some applications require a working X11 display for compilation to succeed. This poses a problem for machines that operate headless. When this variable is used, the build infrastructure will start the virtual framebuffer X server. The working `DISPLAY` is then passed to the build. See crossref:uses[uses-display,`USES=display`] for the possible arguments. [.programlisting] .... USES= display .... [[desktop-entries]] === Desktop Entries Desktop entries (https://standards.freedesktop.org/desktop-entry-spec/latest/[a Freedesktop standard]) provide a way to automatically adjust desktop features when a new program is installed, without requiring user intervention. For example, newly-installed programs automatically appear in the application menus of compatible desktop environments. Desktop entries originated in the GNOME desktop environment, but are now a standard and also work with KDE and Xfce. This bit of automation provides a real benefit to the user, and desktop entries are encouraged for applications which can be used in a desktop environment. [[desktop-entries-predefined]] ==== Using Predefined [.filename]#.desktop# Files Ports that include predefined [.filename]#*.desktop# must include those files in [.filename]#pkg-plist# and install them in the [.filename]#$LOCALBASE/share/applications# directory. The crossref:makefiles[install-macros,`INSTALL_DATA` macro] is useful for installing these files. [[updating-desktop-database]] ==== Updating Desktop Database If a port has a MimeType entry in its [.filename]#portname.desktop#, the desktop database must be updated after install and deinstall. To do this, define `USES`= desktop-file-utils. [[desktop-entries-macro]] ==== Creating Desktop Entries with `DESKTOP_ENTRIES` Desktop entries can be easily created for applications by using `DESKTOP_ENTRIES`. A file named [.filename]#name.desktop# will be created, installed, and added to [.filename]#pkg-plist# automatically. Syntax is: [.programlisting] .... DESKTOP_ENTRIES= "NAME" "COMMENT" "ICON" "COMMAND" "CATEGORY" StartupNotify .... The list of possible categories is available on the https://standards.freedesktop.org/menu-spec/latest/apa.html[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: [.programlisting] .... DESKTOP_ENTRIES= "ToME" "Roguelike game based on JRR Tolkien's work" \ "${DATADIR}/xtra/graf/tome-128.png" \ "tome -v -g" "Application;Game;RolePlaying;" \ false .... [[using-gnome]] == Using GNOME [[using-gnome-introduction]] === 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. [[use-gnome]] === Using `USE_GNOME` Adding this variable to the port allows the use of the macros and components defined in [.filename]#bsd.gnome.mk#. The code in [.filename]#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: [.programlisting] .... USE_GNOME= gtk30 .... `USE_GNOME` components automatically add the dependencies they need. Please see <> for an exhaustive list of all `USE_GNOME` components and which other components they imply and their dependencies. Here is an example [.filename]#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. [.programlisting] .... 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 .... [NOTE] ==== The `USE_GNOME` macro without any arguments does not add any dependencies to the port. `USE_GNOME` cannot be set after [.filename]#bsd.port.pre.mk#. ==== [[using-gnome-variables]] === Variables This section explains which macros are available and how they are used. Like they are used in the above example. The <> 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 [.filename]#gschema.xml# extension. They are installed in the [.filename]#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. + [.programlisting] .... GLIB_SCHEMAS=foo.gschema.xml .... + [NOTE] ==== Do not add glib schemas to the [.filename]#pkg-plist#. If they are listed in [.filename]#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 [.filename]#etc/gconf/schemas# directory. This database is defined by installed schema files that are used to generate [.filename]#%gconf.xml# key files. For each schema file installed by the port, there must be an entry in the [.filename]#Makefile#: + [.programlisting] .... GCONF_SCHEMAS=my_app.schemas my_app2.schemas my_app3.schemas .... + [NOTE] ==== Gconf schemas are listed in the `GCONF_SCHEMAS` macro rather than [.filename]#pkg-plist#. If they are listed in [.filename]#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 [.filename]#Makefile# has `INSTALLS_OMF` defined: + [.programlisting] .... INSTALLS_OMF=yes .... + When set, [.filename]#bsd.gnome.mk# automatically scans [.filename]#pkg-plist# and adds appropriate `@exec` and `@unexec` directives for each [.filename]#.omf# to track in the OMF registration database. [[gnome-components]] == GNOME Components For further help with a GNOME port, look at some of the link:https://www.FreeBSD.org/ports/gnome.html[existing ports] for examples. The link:https://www.FreeBSD.org/gnome/[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.

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 [.filename]#/usr/ports/Mk/Uses/qt.mk#): [[using-qt-library-list]] .Available Qt Library Components [cols="1,1", frame="none", options="header"] |=== | Name | Description |`3d` |Qt3D module |`5compat` |Qt 5 compatibility module for Qt 6 |`assistant` |Qt 5 documentation browser |`base` |Qt 6 base module |`canvas3d` |Qt canvas3d module |`charts` |Qt 5 charts module |`concurrent` |Qt multi-threading module |`connectivity` |Qt connectivity (Bluetooth/NFC) module |`core` |Qt core non-graphical module |`datavis3d` |Qt 5 3D data visualization module |`dbus` |Qt D-Bus inter-process communication module |`declarative` |Qt declarative framework for dynamic user interfaces |`designer` |Qt 5 graphical user interface designer |`diag` |Tool for reporting diagnostic information about Qt and its environment |`doc` |Qt 5 documentation |`examples` |Qt 5 examples sourcecode |`gamepad` |Qt 5 Gamepad Module |`graphicaleffects` |Qt Quick graphical effects |`gui` |Qt graphical user interface module |`help` |Qt online help integration module |`l10n` |Qt localized messages |`languageserver` |Qt 6 Language Server Protocol implementation |`linguist` |Qt 5 translation tool |`location` |Qt location module |`lottie` |Qt 6 QML API for rendering graphics and animations |`multimedia` |Qt audio, video, radio and camera support module |`network` |Qt network module |`networkauth` |Qt network auth module |`opengl` |Qt 5-compatible OpenGL support module |`paths` |Command line client to QStandardPaths |`phonon4` |KDE multimedia framework |`pixeltool` |Qt 5 screen magnifier |`plugininfo` |Qt 5 plugin metadata dumper |`positioning` |Qt 6 positioning API from sources such as satellite, wifi or text files. |`printsupport` |Qt print support module |`qdbus` |Qt command-line interface to D-Bus |`qdbusviewer` |Qt 5 graphical interface to D-Bus |`qdoc` |Qt documentation generator |`qdoc-data` |QDoc configuration files |`qev` |Qt QWidget events introspection tool |`qmake` |Qt Makefile generator |`quickcontrols` |Set of controls for building complete interfaces in Qt Quick |`quickcontrols2` |Set of controls for building complete interfaces in Qt Quick |`remoteobjects` |Qt 5 SXCML module |`script` |Qt 4-compatible scripting module |`scripttools` |Qt Script additional components |`scxml` |Qt 5 SXCML module |`sensors` |Qt sensors module |`serialbus` |Qt functions to access industrial bus systems |`serialport` |Qt functions to access serial ports |`shadertools` |Qt 6 tools for the cross-platform Qt shader pipeline |`speech` |Accessibility features for Qt5 |`sql` |Qt SQL database integration module |`sql-ibase` |Qt InterBase/Firebird database plugin |`sql-mysql` |Qt MySQL database plugin |`sql-odbc` |Qt Open Database Connectivity plugin |`sql-pgsql` |Qt PostgreSQL database plugin |`sql-sqlite2` |Qt SQLite 2 database plugin |`sql-sqlite3` |Qt SQLite 3 database plugin |`sql-tds` |Qt TDS Database Connectivity database plugin |`svg` |Qt SVG support module |`testlib` |Qt unit testing module |`tools` |Qt 6 assorted tools |`translations` |Qt 6 translation module |`uiplugin` |Custom Qt widget plugin interface for Qt Designer |`uitools` |Qt Designer UI forms support module |`virtualkeyboard` |Qt 5 Virtual Keyboard Module |`wayland` |Qt 5 wrapper for Wayland |`webchannel` |Qt 5 library for integration of C++/QML with HTML/js clients |`webengine` |Qt 5 library to render web content |`webkit` |QtWebKit with a more modern WebKit code base |`websockets` |Qt implementation of WebSocket protocol |`websockets-qml` |Qt implementation of WebSocket protocol (QML bindings) |`webview` |Qt component for displaying web content |`widgets` |Qt C++ widgets module |`x11extras` |Qt platform-specific features for X11-based systems |`xml` |Qt SAX and DOM implementations |`xmlpatterns` |Qt support for XPath, XQuery, XSLT and XML Schema |=== To determine the libraries an application depends on, run `ldd` on the main executable after a successful compilation.

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: [.programlisting] .... USES= qt:5 USE_QT= gui buildtools_build qmake_build .... ==== [[using-qmake]] === Using `qmake` If the application provides a qmake project file ([.filename]#*.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 <>, qmake supports out-of-source builds, which can be enabled by specifying the `outsource` argument (see <>). Also see <>. [[using-qmake-arguments]] .Possible Arguments for `USES= qmake` [cols="1,1", frame="none", options="header"] |=== | 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. |=== [[using-qmake-variables]] .Variables for Ports That Use `qmake` [cols="1,1", frame="none", options="header"] |=== | 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 `${CONFIGURE_ENV}`. |`QMAKE_SOURCE_PATH` |Path to qmake project files ([.filename]#.pro#). The default is `${WRKSRC}` if an out-of-source build is requested, empty otherwise. |=== When using `USES= qmake`, these settings are deployed: [.programlisting] ....

Some configure scripts do not support the arguments above. To suppress modification of `CONFIGURE_ENV` and `CONFIGURE_ARGS`, set `USES= qmake:no_env`. [[using-qmake-example]] .`USES= qmake` Example [example] ==== This snippet demonstrates the use of qmake for a Qt 5 port: [.programlisting] .... 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: + [.programlisting] .... 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. package:editors/texmaker[] is an example for this - look at [.filename]#patch-texmaker.pro# in the [.filename]#files# directory of that port for a template on how to remedy this directly in the `qmake` project file. [[using-kde]] == Using KDE [[kde5-variables]] === KDE Variable Definitions 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`).

cmake` instructs the port to utilize CMake, a configuration tool widely used by KDE projects (see <> 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 lxqt qt:5 tar:xz USE_QT= core dbus widgets buildtools_build qmake_build USE_LXQT= buildtools libfmqt .... ==== [[using-java]] == Using Java [[java-variables]] === Variable Definitions If the port needs a Java(TM) Development Kit (JDK(TM)) 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 package:java/openjdk18[], with package:java/openjdk17[], package:java/openjdk16[], package:java/openjdk15[], package:java/openjdk14[], package:java/openjdk13[], package:java/openjdk12[], package:java/openjdk11[], package:java/openjdk8[], and package:java/openjdk7[] also available. [[using-java-variables]] .Variables Which May be Set by Ports That Use Java [cols="1,1", frame="none", options="header"] |=== | 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: `7[+] 8[+] 11[+] 12[+] 13[+] 14[+] 15[+] 16[+] 17[+] 18[+]`). |`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`: [[using-java-variables2]] .Variables Provided to Ports That Use Java [cols="1,1", frame="none", options="header"] |=== | 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, [.filename]#'/usr/local/openjdk6'#). |`JAVAC` |Path to the Java compiler to use (for example, [.filename]#'/usr/local/openjdk6/bin/javac'#). |`JAR` |Path to the `jar` tool to use (for example, [.filename]#'/usr/local/openjdk6/bin/jar'# or [.filename]#'/usr/local/bin/fastjar'#). |`APPLETVIEWER` |Path to the `appletviewer` utility (for example, [.filename]#'/usr/local/openjdk6/bin/appletviewer'#). |`JAVA` |Path to the `java` executable. Use this for executing Java programs (for example, [.filename]#'/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, [.filename]#${JAVA_HOME}/jre/lib/rt.jar#. |=== Use the `java-debug` make target to get information for debugging the port. It will display the value of many of the previously listed variables. Additionally, these constants are defined so all Java ports may be installed in a consistent way: [[using-java-constants]] .Constants Defined for Ports That Use Java [cols="1,1", frame="none", options="header"] |=== | Constant | Value |`JAVASHAREDIR` |The base directory for everything related to Java. Default: [.filename]#${PREFIX}/share/java#. |`JAVAJARDIR` |The directory where JAR files is installed. Default: [.filename]#${JAVASHAREDIR}/classes#. |`JAVALIBDIR` |The directory where JAR files installed by other ports are located. Default: [.filename]#${LOCALBASE}/share/java/classes#. |=== The related entries are defined in both `PLIST_SUB` (documented in crossref:plist[plist-sub,Changing pkg-plist Based on Make Variables]) and `SUB_LIST`. [[java-building-with-ant]] === 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 <>. [[java-best-practices]] === Best Practices When porting a Java library, the port has to install the JAR file(s) in [.filename]#${JAVAJARDIR}#, and everything else under [.filename]#${JAVASHAREDIR}/${PORTNAME}# (except for the documentation, see below). To reduce the packing file size, reference the JAR file(s) directly in the [.filename]#Makefile#. Use this statement (where [.filename]#myport.jar# is the name of the JAR file installed as part of the port): [.programlisting] .... PLIST_FILES+= ${JAVAJARDIR}/myport.jar .... When porting a Java application, the port usually installs everything under a single directory (including its JAR dependencies). The use of [.filename]#${JAVASHAREDIR}/${PORTNAME}# is strongly encouraged in this regard. It is up the porter to decide whether the port installs the additional JAR dependencies under this directory or uses the already installed ones (from [.filename]#${JAVAJARDIR}#). When porting a Java(TM) application that requires an application server such as package:www/tomcat7[] to run the service, it is quite common for a vendor to distribute a [.filename]#.war#. A [.filename]#.war# is a Web application ARchive and is extracted when called by the application. Avoid adding a [.filename]#.war# to [.filename]#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 [.filename]#pkg-plist#. [.programlisting] .... 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 crossref:makefiles[install-documentation,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 ([.filename]#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 [.filename]#pkg-plist# advocates for the use of `PORTDOCS`. The default value for `DATADIR` is [.filename]#${PREFIX}/share/${PORTNAME}#. It is a good idea to override `DATADIR` to [.filename]#${JAVASHAREDIR}/${PORTNAME}# for Java ports. Indeed, `DATADIR` is automatically added to `PLIST_SUB` (documented in crossref:plist[plist-sub,Changing pkg-plist Based on Make Variables]) so use `%%DATADIR%%` directly in [.filename]#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 https://www.freebsd.org/java/[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 [.filename]#bsd.java.mk#. If the port needs more sophisticated Java support, please first have a look at the https://cgit.FreeBSD.org/ports/tree/Mk/bsd.java.mk[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 [.filename]#bsd.java.mk#. Similarly, there is a defined policy regarding the `CATEGORIES` of a Java port, which is detailed in crossref:makefiles[makefile-categories,Categorization]. [[using-php]] == Web Applications, Apache and PHP [[using-apache]] === Apache [[using-apache-variables]] .Variables for Ports That Use Apache [cols="1,1", frame="none"] |=== |`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 [.filename]#ports/Mk/bsd.apache.mk# and at https://wiki.freebsd.org/Apache/[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 [.filename]#bsd.port.pre.mk#. Possible values: `22`, `24`. |`APACHEMODDIR` |Directory for Apache modules. This variable is automatically expanded in [.filename]#pkg-plist#. |`APACHEINCLUDEDIR` |Directory for Apache headers. This variable is automatically expanded in [.filename]#pkg-plist#. |`APACHEETCDIR` |Directory for Apache configuration files. This variable is automatically expanded in [.filename]#pkg-plist#. |=== [[using-apache-modules]] .Useful Variables for Porting Apache Modules [cols="1,1", frame="none"] |=== |`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 [.filename]#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`. |=== [[web-apps]] === Web Applications Web applications must be installed into [.filename]#PREFIX/www/appname#. This path is available both in [.filename]#Makefile# and in [.filename]#pkg-plist# as `WWWDIR`, and the path relative to `PREFIX` is available in [.filename]#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. [IMPORTANT] ==== 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. [[php-variables]] === PHP PHP web applications declare their dependency on it with `USES=php`. See crossref:uses[uses-php,`php`] for more information. [[php-pear]] === PEAR Modules Porting PEAR modules is a very simple process. Add `USES=pear` to the port's [.filename]#Makefile#. The framework will install the relevant files in the right places and automatically generate the plist at install time. [[pear-makefile]] .Example Makefile for PEAR Class [example] ==== [.programlisting] ....

If a port needs to add to `PKGNAMEPREFIX`, it must also use `PEAR_PKGNAMEPREFIX` to differentiate between different flavors. ==== [[php-horde]] ==== Horde Modules In the same way, porting Horde modules is a simple process. Add `USES=horde` to the port's [.filename]#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 [.filename]#Mk/Uses/horde.mk# for a complete list of available modules. [[horde-Makefile]] .Example Makefile for Horde Module [example] ==== [.programlisting] ....

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. [.programlisting] .... PKGNAMEPREFIX= ${PYTHON_PKGNAMEPREFIX} .... [[using-python-variables]] .Most Useful Variables for Ports That Use Python [cols="1,1", frame="none"] |=== |`USES=python` |The port needs Python. The minimal required version can be specified with values such as `2.7+`. Version ranges can also be specified by separating two version numbers with a dash: `USES=python:3.2-3.3` |`USE_PYTHON=distutils` |Use Python distutils for configuring, compiling, and installing. This is required when the port comes with [.filename]#setup.py#. This overrides the `do-build` and `do-install` targets and may also override `do-configure` if `GNU_CONFIGURE` is not defined. Additionally, it implies `USE_PYTHON=flavors`. |`USE_PYTHON=autoplist` |Create the packaging list automatically. This also requires `USE_PYTHON=distutils` to be set. |`USE_PYTHON=concurrent` |The port will use an unique prefix, typically `PYTHON_PKGNAMEPREFIX` for certain directories, such as `EXAMPLESDIR` and `DOCSDIR` and also will append a suffix, the python version from `PYTHON_VER`, to binaries and scripts to be installed. This allows ports to be installed for different Python versions at the same time, which otherwise would install conflicting files. |`USE_PYTHON=flavors` |The port does not use distutils but still supports multiple Python versions. `FLAVORS` will be set to the supported Python versions. See crossref:flavors[flavors-auto-python,`USES`=python and Flavors] for more information. |`USE_PYTHON=optsuffix` |If the current Python version is not the default version, the port will gain `PKGNAMESUFFIX=${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 [.filename]#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. |=== [[using-python-variables-helpers]] .Python Module Dependency Helpers [cols="1,1", frame="none"] |=== |`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 package:devel/py-enum34[] depending on the Python version. |`PY_ENUM_COMPAT` |Conditional dependency on package:devel/py-enum-compat[] depending on the Python version. |`PY_PATHLIB` |Conditional dependency on package:devel/py-pathlib[] depending on the Python version. |`PY_IPADDRESS` |Conditional dependency on package:net/py-ipaddress[] depending on the Python version. |`PY_FUTURES` |Conditional dependency on package:devel/py-futures[] depending on the Python version. |=== A complete list of available variables can be found in [.filename]#/usr/ports/Mk/Uses/python.mk#. [IMPORTANT] ==== All dependencies to Python ports using crossref:flavors[flavors-auto-python,Python flavors] (either with `USE_PYTHON=distutils` or `USE_PYTHON=flavors`) must have the Python flavor appended to their origin using `@${PY_FLAVOR}`. See <>. ==== [[python-Makefile]] .Makefile for a Simple Python Module [example] ==== [.programlisting] .... PORTNAME= sample DISTVERSION= 1.2.3 CATEGORIES= devel MAINTAINER= john@doe.tld COMMENT= Python sample module WWW= https://pypi.org/project/sample/ RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR} USES= python USE_PYTHON= autoplist distutils .include .... ==== 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: [.programlisting] .... (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`. [[using-tcl]] == 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`. [[using-tcl-variables]] .The Most Useful Read-Only Variables for Ports That Use Tcl/Tk [cols="1,1", frame="none"] |=== |`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 |`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 crossref:uses[uses-tcl,`USES=tcl`] and crossref:uses[uses-tk,`USES=tk`] of crossref:uses[uses,Using `USES` Macros] for a full description of those variables. A complete list of those variables is available in [.filename]#/usr/ports/Mk/Uses/tcl.mk#. [[using-sdl]] == Using SDL `USE_SDL` is used to autoconfigure the dependencies for ports which use an SDL based library like package:devel/sdl12[] and package:graphics/sdl_image[]. These SDL libraries for version 1.2 are recognized: * sdl: package:devel/sdl12[] * console: package:devel/sdl_console[] * gfx: package:graphics/sdl_gfx[] * image: package:graphics/sdl_image[] * mixer: package:audio/sdl_mixer[] * mm: package:devel/sdlmm[] * net: package:net/sdl_net[] * pango: package:x11-toolkits/sdl_pango[] * sound: package:audio/sdl_sound[] * ttf: package:graphics/sdl_ttf[] These SDL libraries for version 2.0 are recognized: * sdl: package:devel/sdl20[] * gfx: package:graphics/sdl2_gfx[] * image: package:graphics/sdl2_image[] * mixer: package:audio/sdl2_mixer[] * net: package:net/sdl2_net[] * ttf: package:graphics/sdl2_ttf[] Therefore, if a port has a dependency on package:net/sdl_net[] and package:audio/sdl_mixer[], the syntax will be: [.programlisting] .... USE_SDL= net mixer .... The dependency package:devel/sdl12[], which is required by package:net/sdl_net[] and package: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` [[using-wx]] == Using wxWidgets This section describes the status of the wxWidgets libraries in the ports tree and its integration with the ports system. [[wx-introduction]] === 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. [[wx-version]] === 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): [[wx-ver-sel-table]] .Variables to Select wxWidgets Versions [cols="1,1,1", frame="none", options="header"] |=== | 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: [[wx-widgets-versions-table]] .Available wxWidgets Versions [cols="1,1", frame="none", options="header"] |=== | Version | Port |`2.8` |package:x11-toolkits/wxgtk28[] |`3.0` |package:x11-toolkits/wxgtk30[] |=== The variables in <> can be set to one or more of these combinations separated by spaces: [[wx-widgets-versions-specification]] .wxWidgets Version Specifications [cols="1,1", frame="none", options="header"] |=== | 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.

[[lua-introduction]] === 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 `@${LUA_FLAVOR}` suffix on the port origin. [[lua-version]] === Version Selection A port using Lua should have a line of this form: [.programlisting] .... USES= lua .... If a specific version of Lua, or range of versions, is needed, it can be specified as a parameter in the form `XY` (which may be used multiple times), `XY+`, `-XY`, or `XY-ZA`. The default version of Lua as set via `DEFAULT_VERSIONS` will be used if it falls in the requested range, otherwise the closest requested version to the default will be used. For example: [.programlisting] .... USES= lua:52-53 .... Note that no attempt is made to adjust the version selection based on the presence of any already-installed Lua version. [NOTE] ==== The `XY+` form of version specification should not be used without careful consideration; the Lua API changes to some extent in every version, and configuration tools like CMake or Autoconf will often fail to work on future versions of Lua until updated to do so. ==== [[lua-version-config]] === Configuration and Compiler flags Software that uses Lua may have been written to auto-detect the Lua version in use. In general ports should override this assumption, and force the use of the specific Lua version selected as described above. Depending on the software being ported, this might require any or all of: * Using `LUA_VER` as part of a parameter to the software's configuration script via `CONFIGURE_ARGS` or `CONFIGURE_ENV` (or equivalent for other build systems); * Adding `-I${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. [[lua-version-flavors]] === 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: [.programlisting] .... 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: [.programlisting] .... 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: [.programlisting] .... 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 crossref:uses[uses-uniquefiles,`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`.

USES= iconv CONFIGURE_ARGS+=${ICONV_CONFIGURE_ARG} .... ==== As shown above, `ICONV_LIB` is empty when a native `iconv` is present. This can be used to detect the native `iconv` and respond appropriately. Sometimes a program has an `ld` argument or search path hardcoded in a [.filename]#Makefile# or configure script. This approach can be used to solve that problem: [[iconv-reinplace]] .Fixing Hardcoded `-liconv` [example] ==== [.programlisting] .... USES= iconv post-patch: @${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`.

It is no longer necessary to specify the entire list. If the port only needs package:x11-wm/xfce4-panel[], use: [.programlisting] .... USES= xfce USE_XFCE= panel .... There is no need to list the components package:x11-wm/xfce4-panel[] needs itself like this: [.programlisting] .... USES= xfce USE_XFCE= libexo libmenu libutil panel .... However, Xfce components and non-Xfce dependencies of the port must be included explicitly.

USES= sqlite:3 .... See crossref:uses[uses-sqlite,`sqlite`] for more information. ==== [[rc-scripts]] == Starting and Stopping Services (`rc` Scripts) [.filename]#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 [.filename]#rc.d# framework. Details on its usage can be found in extref:{handbook}[the rc.d Handbook chapter, configtuning-rcd]. Detailed explanation of the available commands is provided in man:rc[8] and man:rc.subr[8]. Finally, there is extref:{rc-scripting}[an article] on practical aspects of [.filename]#rc.d# scripting. With a mythical port called _doorman_, which needs to start a _doormand_ daemon. Add the following to the [.filename]#Makefile#: [.programlisting] .... USE_RC_SUBR= doormand .... Multiple scripts may be listed and will be installed. Scripts must be placed in the [.filename]#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 crossref:pkg-files[using-sub-files,the relevant section]. As of FreeBSD 6.1-RELEASE, local [.filename]#rc.d# scripts (including those installed by ports) are included in the overall man:rcorder[8] of the base system. An example simple [.filename]#rc.d# script to start the doormand daemon: [.programlisting] .... #!/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 "$1" .... Unless there is a very good reason to start the service earlier, or it runs as a particular user (other than root), all ports scripts must use: [.programlisting] .... REQUIRE: LOGIN .... If the startup script launches a daemon that must be shutdown, the following will trigger a stop of the service on system shutdown: [.programlisting] .... KEYWORD: shutdown .... If the script is not starting a persistent service this is not necessary. For optional configuration elements the "=" style of default variable assignment is preferable to the ":=" style here, since the former sets a default value only if the variable is unset, and the latter sets one if the variable is unset _or_ null. A user might very well include something like: [.programlisting] .... doormand_flags="" .... in their [.filename]#rc.conf.local#, and a variable substitution using ":=" would inappropriately override the user's intention. The `_enable` variable is not optional, and must use the ":" for the default. [IMPORTANT] ==== Ports _must not_ start and stop their services when installing and deinstalling. Do not abuse the [.filename]#plist# keywords described in crossref:plist[plist-keywords-base-exec, "the @preexec command,@postexec command,@preunexec command,@postunexec command section"] by running commands that modify the currently running system, including starting or stopping services. ==== [[rc-scripts-checklist]] === Pre-Commit Checklist Before contributing a port with an [.filename]#rc.d# script, and more importantly, before committing one, please consult this checklist to be sure that it is ready. The package:devel/rclint[] port can check for most of these, but it is not a substitute for proper review. [.procedure] . If this is a new file, does it have a [.filename]#.sh# extension? If so, that must be changed to just [.filename]#file.in# since [.filename]#rc.d# files may not end with that extension. . Do the name of the file (minus [.filename]#.in#), the `PROVIDE` line, and `$` _name_ all match? The file name matching `PROVIDE` makes debugging easier, especially for man:rcorder[8] issues. Matching the file name and `$`_name_ makes it easier to figure out which variables are relevant in [.filename]#rc.conf[.local]#. It is also a policy for all new scripts, including those in the base system. . Is the `REQUIRE` line set to `LOGIN`? This is mandatory for scripts that run as a non-root user. If it runs as root, is there a good reason for it to run prior to `LOGIN`? If not, it must run after so that local scrips can be loosely grouped to a point in man:rcorder[8] after most everything in the base is already running. . Does the script start a persistent service? If so, it must have `KEYWORD: shutdown`. . Make sure there is no `KEYWORD: FreeBSD` present. This has not been necessary nor desirable for years. It is also an indication that the new script was copy/pasted from an old script, so extra caution must be given to the review. . If the script uses an interpreted language like `perl`, `python`, or `ruby`, make certain that `command_interpreter` is set appropriately, for example, for Perl, by adding `PERL=${PERL}` to `SUB_LIST` and using `%%PERL%%`. Otherwise, + [source,shell] .... # service name stop .... + will probably not work properly. See man:service[8] for more information. . Have all occurrences of [.filename]#/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 [.filename]#pid# that needs to be owned by the user that runs the process? Rather than the traditional man:touch[1]/man:chown[8]/man:chmod[1] routine, consider using man:install[1] with the proper command line arguments to do the whole procedure with one step. [[users-and-groups]] == 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 [.filename]#ports/UIDs# (for users) and [.filename]#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 [.filename]#Makefile#, and the user will be automatically created when installing the port. [.programlisting] .... USERS= pulse GROUPS= pulse pulse-access pulse-rt .... The current list of reserved UIDs and GIDs can be found in [.filename]#ports/UIDs# and [.filename]#ports/GIDs#. [[requiring-kernel-sources]] == 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: [.programlisting] .... USES= kmod .... Apart from this check, the `kmod` feature takes care of most items that these ports need to take into account. [[go-libs]] == 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. [[haskell-libs]] == 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. [[shell-completion]] == 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`.

USES= pgsql:9.3+ cpe python:2.7,build .... ==== [[uses-7z]] == `7z` Possible arguments: (none), `p7zip`, `partial` Extract using man:7z[1] instead of man:bsdtar[1] and sets `EXTRACT_SUFX=.7z`. The `p7zip` option forces a dependency on the `7z` from package: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 [.filename]#.7z# extension. [[uses-ada]] == `ada` Possible arguments: (none), `5`, `6` Depends on an Ada-capable compiler, and sets `CC` accordingly. Defaults to use gcc 5 from ports. Use the `:_X_` version option to force building with a different version. [[uses-autoreconf]] == `autoreconf` Possible arguments: (none), `build` Runs `autoreconf`. It encapsulates the `aclocal`, `autoconf`, `autoheader`, `automake`, `autopoint`, and `libtoolize` commands. Each command applies to [.filename]#${AUTORECONF_WRKSRC}/configure.ac# or its old name, [.filename]#${AUTORECONF_WRKSRC}/configure.in#. If [.filename]#configure.ac# defines subdirectories with their own [.filename]#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 [.filename]#configure.ac#. [[uses-blaslapack]] == `blaslapack` Possible arguments: (none), `atlas`, `netlib` (default), `gotoblas`, `openblas` Adds dependencies on Blas / Lapack libraries. [[uses-bdb]] == `bdb` Possible arguments: (none), `48`, `5` (default), `6` Add dependency on the Berkeley DB library. Default to package:databases/db5[]. It can also depend on package:databases/db48[] when using the `:48` argument or package: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 package:databases/db5[], it contains `db-5.3`. `BDB_LIB_CXX_NAME`:: The name of the Berkeley DBC++ library. For example, when using package:databases/db5[], it contains `db_cxx-5.3`. `BDB_INCLUDE_DIR`:: The location of the Berkeley DB include directory. For example, when using package:databases/db5[], it will contain `${LOCALBASE}/include/db5`. `BDB_LIB_DIR`:: The location of the Berkeley DB library directory. For example, when using package:databases/db5[], it contains `${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`. [IMPORTANT] ==== package:databases/db48[] is deprecated and unsupported. It must not be used by any port. ==== [[uses-bison]] == `bison` Possible arguments: (none), `build`, `run`, `both` Uses package: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. +[[uses-budgie]] +== `budgie` + +Possible arguments: (none) + +Provide support for the Budgie desktop environment. +Use `USE_BUDGIE` to select the components needed for the port. +See crossref:special[using-budgie,Using Budgie] for more information. + [[uses-cabal]] == `cabal` [IMPORTANT] ==== Ports should not be created for Haskell libraries, see crossref:special[haskell-libs,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 (package:lang/ghc[]) is added. If there is some other version of GHC already listed in the `BUILD_DEPENDS` variable (for example, package:lang/ghc810[]), it would be used instead. If the `hpack` argument is given, a build dependency on package: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 crossref:special[using-cabal,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.${PORTNAME}` and the generated `cabal.project` into a single file after the `patch` stage. Using `append` makes it possible to perform patching on the original file before it gets merged. [[uses-cargo]] == `cargo` Possible arguments: (none) Uses Cargo for configuring, building, and testing. It can be used to port Rust applications that use the Cargo build system. For more information see crossref:special[using-cargo,Building Rust Applications with `cargo`]. [[uses-charsetfix]] == `charsetfix` Possible arguments: (none) Prevents the port from installing [.filename]#charset.alias#. This must be installed only by package:converters/libiconv[]. `CHARSETFIX_MAKEFILEIN` can be set to a path relative to `WRKSRC` if [.filename]#charset.alias# is not installed by [.filename]#${WRKSRC}/Makefile.in#. [[uses-cmake]] == `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 (package: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 crossref:special[using-cmake,Using `cmake`]. [[uses-compiler]] == `compiler` Possible arguments: (none), `env` (default, implicit), `{cpp}17-lang`, `{cpp}14-lang`, `{cpp}11-lang`, `gcc-{cpp}11-lib`, `{cpp}11-lib`, `{cpp}0x`, `c11`, `nestedfct`, `features` Determines which compiler to use based on any given wishes. Use `{cpp}17-lang` if the port needs a {cpp}17-capable compiler, `{cpp}14-lang` if the port needs a {cpp}14-capable compiler, `{cpp}11-lang` if the port needs a {cpp}11-capable compiler, `gcc-{cpp}11-lib` if the port needs the `g++` compiler with a {cpp}11 library, or `{cpp}11-lib` if the port needs a {cpp}11-ready standard library. If the port needs a compiler understanding {cpp}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 [.filename]#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 {cpp} library. [[uses-cpe]] == `cpe` Possible arguments: (none) Include Common Platform Enumeration (CPE) information in package manifest as a CPE 2.3 formatted string. See the https://scap.nist.gov/specifications/cpe/[CPE specification] for details. To add CPE information to a port, follow these steps: [.procedure] . Search for the official CPE entry for the software product either by using the NVD's https://web.nvd.nist.gov/view/cpe/search[CPE search engine] or in the https://nvd.nist.gov/feeds/xml/cpe/dictionary/official-cpe-dictionary_v2.3.xml.gz[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 [.filename]#Mk/Uses/cpe.mk# for additional details, or contact the {ports-secteam}. . 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`. [[uses-cran]] == `cran` Possible arguments: (none), `auto-plist`, `compiles` Uses the Comprehensive R Archive Network. Specify `auto-plist` to automatically generate [.filename]#pkg-plist#. Specify `compiles` if the port has code that need to be compiled. [[uses-desktop-file-utils]] == `desktop-file-utils` Possible arguments: (none) Uses update-desktop-database from package:devel/desktop-file-utils[].

[[uses-display]] == `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. [[uses-dos2unix]] == `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 crossref:slow-porting[slow-patch-automatic-replacements,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}`. [[uses-drupal]] == `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`. [[uses-eigen]] == `eigen` Possible arguments: 2, 3, build (default), run Add dependency on package:math/eigen[].

For example: [.programlisting] .... USES= gnome USE_GNOME= gnomemenus3:build intlhack .... See crossref:special[using-gnome,Using GNOME] for more information. [[uses-go]] == `go` [IMPORTANT] ==== Ports should not be created for Go libs, see crossref:special[go-libs,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 crossref:special[using-go,Building Go Applications] for usage examples. [[uses-gperf]] == `gperf` Possible arguments: (none) Add a buildtime dependency on package:devel/gperf[] if `gperf` is not present in the base system. [[uses-grantlee]] == `grantlee` Possible arguments: `5`, `selfbuild` Handle dependency on Grantlee. Specify `5` to depend on the Qt5 based version, package:devel/grantlee5[]. `selfbuild` is used internally by package:devel/grantlee5[] to get their versions numbers. [[uses-groff]] == `groff` Possible arguments: `build`, `run`, `both` Registers a dependency on package:textproc/groff[] if not present in the base system. [[uses-gssapi]] == `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 package:security/heimdal[], or `mit` to use package: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 package:security/krb5[] and package:security/heimdal[]. For example, use `bootstrap,mit`.

Other Horde dependencies can be added with `USE_HORDE_BUILD` and `USE_HORDE_RUN`. See crossref:special[php-horde,Horde Modules] for more information. [[uses-iconv]] == `iconv` Possible arguments: (none), `lib`, `build`, `patch`, `translit`, `wchar_t` Uses `iconv` functions, either from the port package: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 crossref:special[using-iconv,Using `iconv`]. [[uses-imake]] == `imake` Possible arguments: (none), `env`, `notall`, `noman` Add package: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. [[uses-kde]] == `kde` Possible arguments: `5` Add dependency on KDE components. See crossref:special[using-kde,Using KDE] for more information. [[uses-kmod]] == `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 [.filename]#/boot/modules# by default, add it to `PLIST_SUB` and `MAKE_ENV`, and create it upon installation. If `KMODDIR` is set to [.filename]#/boot/kernel#, it will be rewritten to [.filename]#/boot/modules#. This prevents breaking packages when upgrading the kernel due to [.filename]#/boot/kernel# being renamed to [.filename]#/boot/kernel.old# in the process. * Handle cross-referencing kernel modules upon installation and deinstallation, using crossref:plist[plist-keywords-kld,`@kld`]. * If the `debug` argument is given, the port can install a debug version of the module into [.filename]#KERN_DEBUGDIR#/[.filename]#KMODDIR#. By default, `KERN_DEBUGDIR` is copied from `DEBUGDIR` and set to [.filename]#/usr/lib/debug#. The framework will take care of creating and removing any required directories. [[uses-ldap]] == `ldap` Possible arguments: (none), , client, server Registers a dependency on package:net/openldap[]. It uses the specific `` (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. [[uses-lha]] == `lha` Possible arguments: (none) Set `EXTRACT_SUFX` to `.lzh` [[uses-libarchive]] == `libarchive` Possible arguments: (none) Registers a dependency on package:archivers/libarchive[]. Any ports depending on libarchive must include `USES=libarchive`. [[uses-libedit]] == `libedit` Possible arguments: (none) Registers a dependency on package:devel/libedit[]. Any ports depending on libedit must include `USES=libedit`. [[uses-libtool]] == `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 [.filename]#.la# files. Some ports do not ship with their own copy of libtool and need a build time dependency on package:devel/libtool[], use the `:build` argument to add such dependency. [[uses-linux]] == `linux` Possible arguments: `c6`, `c7` Ports Linux compatibility framework. Specify `c6` to depend on CentOS 6 packags. Specify `c7` to depend on CentOS 7 packages. The available packages are: * `allegro` * `alsa-plugins-oss` * `alsa-plugins-pulseaudio` * `alsalib` * `atk` * `avahi-libs` * `base` * `cairo` * `cups-libs` * `curl` * `cyrus-sasl2` * `dbusglib` * `dbuslibs` * `devtools` * `dri` * `expat` * `flac` * `fontconfig` * `gdkpixbuf2` * `gnutls` * `graphite2` * `gtk2` * `harfbuzz` * `jasper` * `jbigkit` * `jpeg` * `libasyncns` * `libaudiofile` * `libelf` * `libgcrypt` * `libgfortran` * `libgpg-error` * `libmng` * `libogg` * `libpciaccess` * `libsndfile` * `libsoup` * `libssh2` * `libtasn1` * `libthai` * `libtheora` * `libv4l` * `libvorbis` * `libxml2` * `mikmod` * `naslibs` * `ncurses-base` * `nspr` * `nss` * `openal` * `openal-soft` * `openldap` * `openmotif` * `openssl` * `pango` * `pixman` * `png` * `pulseaudio-libs` * `qt` * `qt-x11` * `qtwebkit` * `scimlibs` * `sdl12` * `sdlimage` * `sdlmixer` * `sqlite3` * `tcl85` * `tcp_wrappers-libs` * `tiff` * `tk85` * `ucl` * `xorglibs` [[uses-llvm]] == `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 [[uses-localbase]] == `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`. [[uses-lua]] == `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 crossref:special[using-lua,Using Lua]. [[uses-luajit]] == `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 [.filename]#bsd.port.options.mk# or [.filename]#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 crossref:special[using-lua,Using Lua]. [[uses-lxqt]] == `lxqt` Possible arguments: (none) Handle dependencies for the LXQt Desktop Environment. Use `USE_LXQT` to select the components needed for the port. See crossref:special[using-lxqt,Using LXQt] for more information. [[uses-magick]] == `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. [[uses-makeinfo]] == `makeinfo` Possible arguments: (none) Add a build-time dependency on `makeinfo` if it is not present in the base system. [[uses-makeself]] == `makeself` Possible arguments: (none) Indicates that the distribution files are makeself archives and sets the appropriate dependencies. [[uses-mate]] == `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: [.programlisting] .... USES= mate USE_MATE= menus:build intlhack .... [[uses-meson]] == `meson` Possible arguments: (none) Provide support for Meson based projects. For more information see crossref:special[using-meson,Using `meson`]. [[uses-metaport]] == `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`. [[uses-minizip]] == `minizip` Possible arguments: (none), `ng` Adds a library dependency on package:archivers/minizip[] or package:archivers/minizip-ng[] respectively. [[uses-mysql]] == `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 [.filename]#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. [[uses-mono]] == `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 [.filename]#packages.config#. [[uses-motif]] == `motif` Possible arguments: (none) Uses package:x11-toolkits/open-motif[] as a library dependency. End users can set `WANT_LESSTIF` in [.filename]#make.conf# to use package:x11-toolkits/lesstif[] as dependency instead of package:x11-toolkits/open-motif[]. Similarly setting `WANT_OPEN_MOTIF_DEVEL` in [.filename]#make.conf# will add a dependency on package:x11-toolkits/open-motif-devel[] [[uses-ncurses]] == `ncurses` Possible arguments: (none), `base`, `port` Uses ncurses, and causes some useful variables to be set. [[uses-ninja]] == `ninja` Possible arguments: (none) Uses ninja to build the port. [[uses-nodejs]] == `nodejs` Possible arguments: (none), `build`, `run`, `current`, `lts`, `10`, `14`, `16`, `17`. Uses nodejs. Adds a dependency on package:www/node*[]. If a supported version is specified then `run` and/or `build` must be specified too. [[uses-objc]] == `objc` Possible arguments: (none) Add objective C dependencies (compiler, runtime library) if the base system does not support it. [[uses-octave]] == `octave` Possible arguments: (none), env Uses package:math/octave[]. `env` loads only one `OCTAVE_VERSION` environmental variable. [[uses-openal]] == `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`. [[uses-pathfix]] == `pathfix` Possible arguments: (none) Look for [.filename]#Makefile.in# and [.filename]#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 [.filename]#.pc# files to [.filename]#${PREFIX}/libdata/pkgconfig#. If the port uses `USES=autoreconf`, [.filename]#Makefile.am# will be added to `PATHFIX_MAKEFILEIN` automatically. If the port <> it will look for [.filename]#CMakeLists.txt# in `PATHFIX_WRKSRC`. If needed, that default filename can be changed with `PATHFIX_CMAKELISTSTXT`. [[uses-pear]] == `pear` Possible arguments: `env` Adds a dependency on package: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 crossref:special[php-pear,PEAR Modules] for more information. [[uses-perl5]] == `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 [.filename]#Makefile.PL#, [.filename]#Build.PL#, or Module::Build::Tiny's flavor of [.filename]#Build.PL# is required. `USE_PERL5` defaults to `build run`. When using `configure`, `modbuild`, or `modbuildtiny`, `build` and `run` are implied. See crossref:special[using-perl,Using Perl] for more information. [[uses-pgsql]] == `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` [[uses-php]] == `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, package: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 crossref:flavors[flavors-auto-php,PHP flavors] generation. Flavors will be generated for all PHP versions, except the ones present in <>. `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` [[uses-php-ignore]] `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 [.filename]#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 package: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: + [.programlisting] .... 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. [IMPORTANT] ==== 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`. ==== [[uses-pkgconfig]] == `pkgconfig` Possible arguments: (none), `build` (default), `run`, `both` Uses package: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. [[uses-pure]] == `pure` Possible arguments: (none), `ffi` Uses package:lang/pure[]. Largely used for building related pure ports. With the `ffi` argument, it implies package:devel/pure-ffi[] as a run-time dependency. [[uses-pyqt]] == `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` * `xml` * `xmlpatterns` These components are only available with PyQT4: * `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: [.programlisting] .... USES= pyqt USE_PYQT= core doc_build designer_run .... [[uses-pytest]] == `pytest` Possible arguments: (none), 4 Introduces a new dependency on package:devel/pytest[]. It defines a `do-test` target which will run the tests properly. Use the argument to depend on a specific package:devel/pytest[] version. For ports using package: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`. [[uses-python]] == `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 crossref:special[using-python, Using Python] for more information. `PYTHON_NO_DEPENDS=yes` 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 <>, and the goal is only to fix the shebangs but not add a dependency on Python. [[uses-qmail]] == `qmail` Possible arguments: (none), `build`, `run`, `both`, `vars` Uses package: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. [[uses-qmake]] == `qmake` Possible arguments: (none), `norecursive`, `outsource`, `no_env`, `no_configure` Uses QMake for configuring. For more information see crossref:special[using-qmake,Using `qmake`]. [[uses-qt]] == `qt` Possible arguments: `5`, `6`, `no_env` Add dependency on Qt components. `no_env` is passed directly to `USES= qmake`. See crossref:special[using-qt,Using Qt] for more information. [[uses-qt-dist]] == `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. [[qt5-dist-example]] .Building Qt 5 Components [example] ==== The port is Qt 5's `networkauth` component, which is part of the `networkauth` distribution file. [.programlisting] .... PORTNAME= networkauth DISTVERSION= ${QT5_VERSION} USES= qt-dist:5 .... ==== [[qt6-dist-example]] .Building Qt 6 Components [example] ==== The port is Qt 6's `websockets` component, which is part of the `websockets` distribution file. [.programlisting] .... 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`. [[qt5-dist-example-explicit]] .Building Qt 5 Components with Different Names [example] ==== The port is Qt 5's `gui` component, which is part of the `base` distribution file. [.programlisting] .... PORTNAME= gui DISTVERSION= ${QT5_VERSION} USES= qt-dist:5,base .... ==== [[uses-readline]] == `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 package:devel/readline[] [[uses-ruby]] == `ruby` Possible arguments: (none), `build`, `extconf`, `run`, `setup` Provide support for Ruby related ports. `(none)` without arguments adds runtime dependency on package:lang/ruby[]. `build` adds a dependency on package:lang/ruby[] at build time. `extconf` states that the port uses extconf.rb to configure. `run` adds a dependency on package: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). [[uses-samba]] == `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 [.filename]#smbd#. `lib` will add a dependency on [.filename]#libsmbclient.so#. The variables that are exported are: `SAMBAPORT`:: The origin of the default Samba port. `SAMBAINCLUDES`:: The location of the Samba header files. `SAMBALIBS`:: The directory where the Samba shared libraries are available. [[uses-scons]] == `scons` Possible arguments: (none) Provide support for the use of package:devel/scons[]. See crossref:special[using-scons,Using `scons`] for more information. [[uses-shared-mime-info]] == `shared-mime-info` Possible arguments: (none) Uses update-mime-database from package: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 crossref:plist[plist-keywords-shared-mime-info,`@shared-mime-info`] entry to the plist. [[uses-shebangfix]] == `shebangfix` Possible arguments: (none) A lot of software uses incorrect locations for script interpreters, most notably [.filename]#/usr/bin/perl# and [.filename]#/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 man:find[1]. See <>. `SHEBANG_GLOB`:: Contains a list of patterns used with the `-name` argument of man:find[1]. See <>. `SHEBANG_FILES`:: Contains a list of files or man: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 <>. 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`. + [NOTE] ==== These will _always_ be part of `_interp__OLD_CMD`: `"/usr/bin/env _interp_" /bin/_interp_ /usr/bin/_interp_ /usr/local/bin/_interp_`. ==== + [TIP] ==== `_interp__OLD_CMD` contain multiple values. Any entry with spaces must be quoted. See <>. ==== [IMPORTANT] ==== 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 [.filename]#configure# script, or the [.filename]#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`. ==== [TIP] ==== When used with <>, and the aim is only to fix the shebangs but a dependency on Python itself is not wanted, use `PYTHON_NO_DEPENDS=yes`. ==== [[uses-shebangfix-ex-lua]] .Adding Another Interpreter to `USES=shebangfix` [example] ==== To add another interpreter, set `SHEBANG_LANG`. For example: [.programlisting] .... SHEBANG_LANG= lua .... ==== [[uses-shebangfix-ex-ksh]] .Specifying all the Paths When Adding an Interpreter to `USES=shebangfix` [example] ==== If it was not already defined, and there were no default values for `_interp__OLD_CMD` and `_interp__CMD` the Ksh entry could be defined as: [.programlisting] .... SHEBANG_LANG= ksh ksh_OLD_CMD= "/usr/bin/env ksh" /bin/ksh /usr/bin/ksh ksh_CMD= ${LOCALBASE}/bin/ksh .... ==== [[uses-shebangfix-ex-strange]] .Adding a Strange Location for an Interpreter [example] ==== Some software uses strange locations for an interpreter. For example, an application might expect Python to be located in [.filename]#/opt/bin/python2.7#. The strange path to be replaced can be declared in the port [.filename]#Makefile#: [.programlisting] .... python_OLD_CMD= /opt/bin/python2.7 .... ==== [[uses-shebangfix-ex-regex]] .`USES=shebangfix` with `SHEBANG_REGEX` [example] ==== To fix all the files in `${WRKSRC}/scripts` ending in [.filename]#.pl#, [.filename]#.sh#, or [.filename]#.cgi# do: [.programlisting] .... USES= shebangfix SHEBANG_REGEX= ./scripts/.*\.(sh|pl|cgi) .... [NOTE] ====== `SHEBANG_REGEX` is used by running `find -E`, which uses modern regular expressions also known as extended regular expressions. See man:re_format[7] for more information. ====== ==== [[uses-shebangfix-ex-glob]] .`USES=shebangfix` with `SHEBANG_GLOB` [example] ==== To fix all the files in `${WRKSRC}` ending in [.filename]#.pl# or [.filename]#.sh#, do: [.programlisting] .... USES= shebangfix SHEBANG_GLOB= *.sh *.pl .... ==== [[uses-shebangfix-ex-files]] .`USES=shebangfix` with `SHEBANG_FILES` [example] ==== To fix the files [.filename]#script/foobar.pl# and [.filename]#script/*.sh# in `${WRKSRC}`, do: [.programlisting] .... USES= shebangfix SHEBANG_FILES= scripts/foobar.pl scripts/*.sh .... ==== [[uses-sqlite]] == `sqlite` Possible arguments: (none), `2`, `3` Add a dependency on SQLite.

[TIP] ==== If a port does not build with an OpenSSL flavor, set the `BROKEN_SSL` variable, and possibly the `BROKEN_SSL_REASON__flavor_`: [.programlisting] .... BROKEN_SSL= libressl BROKEN_SSL_REASON_libressl= needs features only available in OpenSSL .... ==== [[uses-tar]] == `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. [[uses-tcl]] == `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 [.filename]#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 * `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 [[uses-terminfo]] == `terminfo` Possible arguments: (none) Adds crossref:plist[plist-keywords-terminfo,`@terminfo`] to the [.filename]#plist#. Use when the port installs [.filename]#*.terminfo# files in [.filename]#${PREFIX}/share/misc#. [[uses-tex]] == `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.

The same variables are returned as when using Tcl. [[uses-uidfix]] == `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 <> or patching. [[uses-uniquefiles]] == `uniquefiles` Possible arguments: (none), `dirs` Make files or directories 'unique', by adding a prefix or suffix. If the `dirs` argument is used, the port needs a prefix (and only a prefix) based on `UNIQUE_PREFIX` for standard directories `DOCSDIR`, `EXAMPLESDIR`, `DATADIR`, `WWWDIR`, `ETCDIR`. These variables are available for ports: * `UNIQUE_PREFIX`: The prefix to be used for directories and files. Default: `${PKGNAMEPREFIX}`. * `UNIQUE_PREFIX_FILES`: A list of files that need to be prefixed. Default: empty. * `UNIQUE_SUFFIX`: The suffix to be used for files. Default: `${PKGNAMESUFFIX}`. * `UNIQUE_SUFFIX_FILES`: A list of files that need to be suffixed. Default: empty.

[[uses-varnish]] == `varnish` Possible arguments: `4` (default), `6`, `7` Handle dependencies on Varnish Cache. Adds a dependency on package:www/varnish*[]. [[uses-webplugin]] == `webplugin` Possible arguments: (none), `ARGS` Automatically create and remove symbolic links for each application that supports the webplugin framework. `ARGS` can be one of: * `gecko`: support plug-ins based on Gecko * `native`: support plug-ins for Gecko, Opera, and WebKit-GTK * `linux`: support Linux plug-ins * `all` (default, implicit): support all plug-in types * (individual entries): support only the browsers listed These variables can be adjusted: * `WEBPLUGIN_FILES`: No default, must be set manually. The plug-in files to install. * `WEBPLUGIN_DIR`: The directory to install the plug-in files to, default [.filename]#PREFIX/lib/browser_plugins/WEBPLUGIN_NAME#. Set this if the port installs plug-in files outside of the default directory to prevent broken symbolic links. * `WEBPLUGIN_NAME`: The final directory to install the plug-in files into, default `PKGBASE`. [[uses-xfce]] == `xfce` Possible arguments: (none), `gtk2` Provide support for Xfce related ports. See crossref:special[using-xfce,Using Xfce] for details. The `gtk2` argument specifies that the port requires GTK2 support.

The second argument is the build system to use. autotools is the default, but meson is also supported. [[uses-zip]] == `zip` Possible arguments: (none), `infozip` Indicates that the distribution files use the ZIP compression algorithm. For files using the InfoZip algorithm the `infozip` argument must be passed to set the appropriate dependencies.
