PORTS(7) FreeBSD Miscellaneous Information Manual PORTS(7)

contributed applications

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). It can be installed and updated using portsnap(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.
For more information about using ports, see the “Packages and Ports section” in The FreeBSD Handbook:
For information about creating new ports, see The Porter's Handbook :

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.
The following targets will be run automatically by each proceeding target in order. That is, build will be run (if necessary) by install, and so on all the way to fetch. Usually, you will only use the install target.
Configure OPTIONS for this port using dialog4ports(1).
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.
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.
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.
Expand the distfile into a work directory.
Apply any patches that are necessary for the port.
Configure the port. Some ports will ask you questions during this stage. See INTERACTIVE and BATCH.
Build the port. This is the same as calling the all target.
Install the port and register it with the package system. This is all you really need to do.
The following targets are not run during the normal install process.
Display OPTIONS config for this port.
Display OPTIONS config for this port and all its dependencies.
Remove OPTIONS config for this port.
Remove OPTIONS config for this port and all its dependencies.
Skip the ports which have already had their OPTIONS configured.
Configure OPTIONS for this port and all its dependencies using dialog4ports(1).
Show list of files to be fetched in order to build the port.
Fetch the distfiles of the port and all its dependencies.
Show list of files that would be retrieved by fetch-recursive.
, build-depends-list
Print a list of all the compile and run dependencies, and dependencies of those dependencies, by port directory.
Print a list of all dependencies for the port.
, pretty-print-build-depends-list
Print a list of all the compile and run dependencies, and dependencies of those dependencies, by port name and version.
Print a list of missing dependencies to be installed for the port.
Remove the expanded source code. This recurses to dependencies unless NOCLEANDEPENDS is defined.
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).
Use this to restore a port after using pkg-delete(8) when you should have used deinstall.
Remove an installed port from the system, similar to pkg-delete(8).
Remove all installed ports with the same PKGORIGIN from the system.
Make a binary package for the port. The port will be installed if it has not already been. The package is a .tbz 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 into the current directory. See PKGREPOSITORY and PKGFILE.
Like package, but makes a package for each depending port as well.
Prints the name with version of the port.
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 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 name matches “query”. Results include the matching ports' path, comment, maintainer, build dependencies, and run dependencies.
cd /usr/ports && make search name=pear- \ 
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- \ 
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
Reduced search output. Only display name, path and info.
Generate a one-line description of each port for use in the INDEX file.
Display the port maintainer's email address.
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.
Fetch the INDEX file from the FreeBSD cluster.

You can change all of these.
Location of the ports tree. This is /usr/ports on FreeBSD and OpenBSD, and /usr/pkgsrc on NetBSD.
Where to create any temporary files. Useful if PORTSDIR is read-only (perhaps mounted from a CD-ROM).
Where to find/put distfiles, normally distfiles/ in PORTSDIR.
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
Directory to put the package in.
The full path to the package.
Where existing things are installed and where to search for files when resolving dependencies (usually /usr/local).
Where to install this port (usually set to the same as LOCALBASE).
Primary sites for distribution files if not found locally.
Primary locations for distribution patch files if not found locally.
If set, go to the master FreeBSD site for all files.
Try going to these sites for all files and patches, first.
Try going to these sites for all files and patches, last.
Try the download locations in a random order.
Sort the download locations according to user supplied pattern. Example:
.dk .se .no .de
Where to get INDEX source built on FreeBSD cluster (for fetchindex target). Defaults to
Command to get INDEX (for fetchindex target). Defaults to “fetch -am”.
If defined, do not let clean recurse to dependencies.
Command to use to fetch files. Normally fetch(1).
If set, overwrite any existing package registration on the system.
Location of libXm.{a,so}.
If defined, only operate on a port if it requires interaction.
If defined, only operate on a port if it can be installed 100% automatically.
If defined, disable check for security vulnerabilities using pkg-audit(8) when installing new ports.
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 you do it.
If defined, skip verifying the port's checksum.
If defined, attempt to build a port even if it is marked as ⟨BROKEN⟩.
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.

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.
(bool) If set, causes ports that make use of OpenSSL to use the OpenSSL from ports (if available) instead of the OpenSSL from the base system.
(bool) If set, debugging symbols are installed for ports binaries.
A list of origins for which to set WITH_DEBUG_PORTS.
(bool) If set, enables -fstack-protector for most ports.
If set, the version of ghostscript to be used by ports.
(bool) If set, enables the use of ccache(1) for building ports.
Which directory to use for the ccache(1) data.

The default ports directory.

Additional user documentation:

The Ports Collection appeared in FreeBSD 1.0. It has since spread to NetBSD and OpenBSD.

This manual page was originated by David O'Brien.

Ports documentation is split over four places — /usr/ports/Mk/, The Porter's Handbook, the “Packages and Ports” chapter of The FreeBSD Handbook, and this manual page.
