PORTS(7) FreeBSD Miscellaneous Information Manual PORTS(7)
NAME ports - contributed applications
DESCRIPTION The FreeBSD Ports Collection offers a simple way to compile and install third party applications. It is also used to build packages, to be installed using pkg(8).
The ports tree, typically located at /usr/ports, consists of subdirectories, one for each category; those in turn contain individual ports. Each port is a directory with metadata and patches necessary to make the original application source code compile and run on FreeBSD. Compiling an application is as simple as typing "make build" in the port directory. The Makefile automatically fetches the application source code, either from a local disk or the network, unpacks it, applies the patches, and compiles it. It also recursively handles dependencies -- other pieces of software the port depends on in order to build and work. Afterwards, "make install" installs the application.
The FreeBSD Ports Collection is maintained in several branches, which differ mostly by versions of software provided: the main branch contains all the latest changes and corresponds to the latest package set, while the quarterly branches only provide critical fixes. The main branch can be cloned and updated from the Git repository located at:
https://git.FreeBSD.org/ports.git
so eg:
git clone https://git.FreeBSD.org/ports.git
The quarterly branches can be found in Git as branches like yyyyQn , where yyyy indicates the year and n indicates the quarter (1 to 4), eg:
git clone -b 2021Q2 https://git.FreeBSD.org/ports.git
It is generally a good idea to use the ports branch that matches the pkg(8) repository being used. By default, for FreeBSD CURRENT the pkg(8) is configured to install packages built from the main branch, while for FreeBSD STABLE or RELEASE versions it is configured to install packages built from the latest quarterly branch. Currently configured pkg(8) repository can be verified by looking at the url field in pkg -vv output.

TARGETS Some of the make(1) targets work recursively through subdirectories. This lets you, for example, install all of the "biology" ports with one command. The targets that do this are build, checksum, clean, configure, depends, extract, fetch, install, and package. fetch Fetch all of the files needed to build this port from the sites listed in MASTER_SITES and PATCH_SITES. See FETCH_CMD, MASTER_SITE_OVERRIDE and MASTER_SITE_BACKUP.
checksum Verify that the fetched distfile's checksum matches the one the port was tested against. If the distfile's checksum does not match, it also fetches the distfiles which are missing or failed the checksum calculation. Defining NO_CHECKSUM will skip this step.
depends Install (or compile if only compilation is necessary) any dependencies of the current port. When called by the extract or fetch targets, this is run in piecemeal as fetch-depends, build-depends, etc. Defining NO_DEPENDS will skip this step.
extract Expand the distfile into a work directory.
patch Apply any patches that are necessary for the port.
configure Configure the port. Some ports will ask you questions during this stage. See INTERACTIVE and BATCH.
build Build the port. This is the same as calling the all target.
install Install the port and register it with the package system. This is all you really need to do.
install-missing-packages Install missing dependencies from packages instead of building them.
The following targets are not run during the normal install process.
showconfig Display OPTIONS config for this port.
showconfig-recursive Display OPTIONS config for this port and all its dependencies.
rmconfig Remove OPTIONS config for this port.
rmconfig-recursive Remove OPTIONS config for this port and all its dependencies.
config-conditional Skip the ports which have already had their OPTIONS configured.
config-recursive Configure OPTIONS for this port and all its dependencies using dialog4ports(1).
fetch-list Show the list of files to fetch in order to build the port (but not its dependencies).
fetch-recursive Fetch the distfiles of the port and all its dependencies.

all-depends-list Print a list of all recursive dependencies for this port.
pretty-print-build-depends-list, pretty-print-run-depends-list Print a list of all the recursive compile or run dependencies for this port by port name and version.
missing Print a list of missing dependencies to be installed for the port.
clean Remove the expanded source code. This recurses to dependencies unless NOCLEANDEPENDS is defined.
distclean Remove the port's distfiles and perform the clean target. The clean portion recurses to dependencies unless NOCLEANDEPENDS is defined, but the distclean portion never recurses (this is perhaps a bug).
reinstall Use this to restore a port after using pkg-delete(8) when you should have used deinstall.
deinstall Remove an installed port from the system, similar to pkg-delete(8).
deinstall-all Remove all installed ports with the same PKGORIGIN from the system.
package Make a binary package for the port. The port will be installed if it has not already been. The package is a .pkg file that you can use to install the port on other machines with pkg-add(8). If the directory specified by PACKAGES does not exist, the package will be put in /usr/ports/category/port/work/pkg. See PKGREPOSITORY and PKGFILE for more information.
package-recursive Like package, but makes a package for each depending port as well.
package-name Prints the name with version of the port.
readmes Create a port's README.html. This can be used from /usr/ports to create a browsable web of all ports on your system!
search Search the INDEX file for the pattern specified by the key (searches the port name, comment, and dependencies), name (searches the port name only), path (searches the port path), info (searches the port info), maint (searches the port maintainer), cat (searches the port category), bdeps (searches the port build-time dependency), rdeps (searches the port run-time dependency), www (searches the port web site) make(1) variables, and their exclusion counterparts: xname, xkey etc. For example, one would type:
cd /usr/ports && make search name=query
To find all ports whose names contain "pear-" and which do not have apache listed in build-time dependencies.
cd /usr/ports && make search name=pear- \ xname='ht(tp|ml)'
To find all ports whose names contain "pear-", but not "html" or "http".
make search key=apache display=name,path,info keylim=1
To find ports that contain "apache" in either of the name, path, info fields, ignore the rest of the record.
By default the search is not case-sensitive. In order to make it case-sensitive you can use the icase variable:
make search name=p5-R icase=0
quicksearch Reduced search output. Only display name, path and info.
describe Generate a one-line description of each port for use in the INDEX file.
maintainer Display the port maintainer's email address.
index Create /usr/ports/INDEX, which is used by the pretty-print-* and search targets. Running the index target will ensure your INDEX file is up to date with your ports tree.
fetchindex Fetch the INDEX file from the FreeBSD cluster.
ENVIRONMENT You can change all of these.
PORTSDIR Location of the ports tree. This is /usr/ports by default.
WRKDIRPREFIX Where to create any temporary files. Useful if PORTSDIR is read-only (perhaps mounted from a CD-ROM).
DISTDIR Where to find/put distfiles, normally distfiles/ in PORTSDIR.
SU_CMD Command used to elevate privilege to configure and install a port. The unprivileged user must have write access to WRKDIRPREFIX and DISTDIR. The default is `/usr/bin/su root -c'. Many users set it to `/usr/local/bin/sudo -E sh -c' for convenience.
PACKAGES Used only for the package target; the base directory for the packages tree, normally packages/ in PORTSDIR. If this directory exists, the package tree will be (partially) constructed. This directory does not have to exist; if it does not, packages will be placed into the current directory, or you can define one of
PREFIX Where to install this port (usually set to the same as LOCALBASE).
MASTER_SITES Primary sites for distribution files if not found locally.
PATCH_SITES Primary locations for distribution patch files if not found locally.
MASTER_SITE_FREEBSD If set, go to the master FreeBSD site for all files.
MASTER_SITE_OVERRIDE Try going to these sites for all files and patches, first.
MASTER_SITE_BACKUP Try going to these sites for all files and patches, last.
RANDOMIZE_MASTER_SITES Try the download locations in a random order.
MASTER_SORT Sort the download locations according to user supplied pattern. Example: .dk .sunet.se .se dk.php.net .no .de heanet.dl.sourceforge.net
MASTER_SITE_INDEX Where to get INDEX source built on FreeBSD cluster (for fetchindex target). Defaults to https://www.FreeBSD.org/ports/.
FETCHINDEX Command to get INDEX (for fetchindex target). Defaults to "fetch -am".
NOCLEANDEPENDS If defined, do not let clean recurse to dependencies.
FETCH_CMD Command to use to fetch files. Normally fetch(1).
FORCE_PKG_REGISTER If set, overwrite any existing package registration on the system.
INTERACTIVE If defined, only operate on a port if it requires interaction.
BATCH If defined, only operate on a port if it can be installed 100% automatically.
DISABLE_VULNERABILITIES If defined, disable check for security vulnerabilities using pkg-audit(8) when installing new ports.
NO_IGNORE If defined, allow installation of ports marked as <FORBIDDEN>. The default behavior of the Ports framework is to abort when the installation of a forbidden port is attempted. Of course, these ports may not work as expected, but if you really know what you are doing and are sure about installing a forbidden port, then NO_IGNORE lets
PORT_DBDIR Directory where the results of configuring OPTIONS are stored. Defaults to /var/db/ports. Each port where OPTIONS have been configured will have a uniquely named sub-directory, containing a single file options.
MAKE VARIABLES The following list provides a name and short description for many of the variables that are used when building ports. More information on these and other related variables may be found in ${PORTSDIR}/Mk/* and the FreeBSD Porter's Handbook.
WITH_DEBUG (bool) If set, debugging symbols are installed for ports binaries.
WITH_DEBUG_PORTS A list of origins for which to set WITH_DEBUG.
DEBUG_FLAGS (Default: `-g') Additional CFLAGS to set when WITH_DEBUG is set.
WITH_CCACHE_BUILD (bool) If set, enables the use of ccache(1) for building ports.
CCACHE_DIR Which directory to use for the ccache(1) data.
FILES /usr/ports The default ports directory. /usr/ports/Mk/bsd.port.mk The big Kahuna.
EXAMPLES Example 1: Building and Installing a Port
The following command builds and installs Emacs.
# cd /usr/ports/editors/emacs # make install
Example 2: Installing Dependencies with pkg(8)
The following example shows how to build and install a port without having to build its dependencies. Instead, the dependencies are downloaded via pkg(8).
# make install-missing-packages # make install
It is especially useful, when the dependencies are costly in time and resources to build (like lang/rust). The drawback is that pkg(8) offers only packages built with the default set of OPTIONS.
Example 3: Building a Non-Default Flavor of a Port
The following command builds a non-default flavor of a port. (In this case devel/py-pip is going to be built with Python 3.7 support.)
# cd /usr/ports/devel/py-pip # env FLAVOR=py37 make build
Example 4: Setting Ports Options via make.conf(5)
# via the options dialog. OPTIONS_UNSET_FORCE= DOCS # Disable DOCS and EXAMPLES for the shells/zsh port. shells_zsh_UNSET= DOCS EXAMPLES
These and other options-related variables are documented in /usr/ports/Mk/bsd.options.mk.
Example 5: Setting make(1) Variables for Specific Ports via make.conf(5)
The following example shows how to set arbitrary make(1) variables only specific ports:
# Set DISABLE_MAKE_JOBS for the lang/rust port: .if ${.CURDIR:M*/lang/rust} DISABLE_MAKE_JOBS= yes TRYBROKEN= yes .endif
Example 6: Debugging Ports By default ports are built and packaged without debugging support (e.g., debugging symbols are stripped from binaries, optimization flags are used for compiling, verbose logging is disabled). Whether ports are built with debugging symbols can be controlled by the settings in make.conf(5), e.g.,
# Enable debugging for all ports. WITH_DEBUG= yes # Enable debugging for selected ports. WITH_DEBUG_PORTS= mail/dovecot security/krb5
It is also possible to use the debug variables on the command line:
# make -DWITH_DEBUG DEBUG_FLAGS="-g -O0" build
See the MAKE VARIABLES section to learn more about the debug variables.
To understand the details of what happens when the debug variables are set it is best to consult the files located at ${PORTSDIR}/Mk/* (bsd.port.mk in particular).
If debugging is enabled for a specific port, the ports framework will:
o Add DEBUG_FLAGS (defaults to `-g') to CFLAGS.
o Try to prevent the binaries from being stripped (including checking the install target to replace `install-strip' with `install'). Whether a binary has been stripped can be checked with file(1).
o Try to enable other debugging features like debug build type or verbose logging. However, this is port-specific and the ports framework might not be aware of each supported debugging feature a given piece of software has to offer).
