NAME
ports - contributed applications
DESCRIPTION
The OpenBSD Ports Collection is the infrastructure used to create binary
packages for third party applications.
For normal usage refer to packages(7), as most ports produce binary
packages which are available from the official HTTP mirrors.
Each port contains any patches necessary to make the original application
source code compile and run on OpenBSD. Compiling an application is as
simple as typing make in the port directory! The Makefile automatically
fetches the application source code, either from a local disk or via
HTTP, unpacks it on the local system, applies the patches, and compiles
it. If all goes well, simply type doas make install to install the
application.
For more information about using ports, see Working with Ports:
https://www.openbsd.org/faq/ports/ports.html. For information about
creating new ports, see The OpenBSD Porter's Handbook:
https://www.openbsd.org/faq/ports/.
For a detailed description of the build process, see bsd.port.mk(5).
PORTS MASTER MAKEFILE
The ports master Makefile, normally located in /usr/ports/Makefile (but
see PORTSDIR below) offers a few deprecated targets for the time being.
print-index display the contents of the index in a `user-friendly' way,
search invoked with a key, e.g., make search key=foo, retrieve
information relevant to a given port (obsolescent).
Starting in OpenBSD 4.0, there is a port, databases/sqlports, that builds
an sqlite database containing most information relevant to every port in
the ports tree. This database can be searched using any tool able to
manipulate such databases, for instance sqlitebrowser, or a script
language with an sqlite interface, e.g., perl, python, ocaml, lua, php.
All static index generating information has now been superseded by the
sqlports, portslist or pkglocatedb packages, which contain similar
information to the old INDEX file, but are frequently updated. See
databases/sqlports databases/pkglocatedb and pkg_mklocatedb(1) for
details.
SELECTING A SET OF PORTS
One can define SUBDIRLIST to point to a file that contains a list of
FULLPKGPATHs, one per line, to build stuff only in some directories.
If portslist is up to date, it is possible to select subsets by setting
the following variables on the command line:
key package name matching the given key,
category port belonging to category,
maintainer
port maintained by a given person.
For instance, to invoke clean on all ports in the x11 category, one can
say:
$ make category=x11 clean
The index search is done by a perl script, so all regular expressions
from perlre(1) apply.
TARGETS
Individual ports are controlled through a few documented targets. Some
of these targets work recursively through subdirectories, so that someone
can, for example, install all of the net ports.
The variable SKIPDIR can hold a set of package directories to avoid
during recursion. These are always specified relative to the root of the
ports tree, and can contain a flavor or subpackage part (see
packages-specs(7)). SKIPDIR is handled by a case statement, and so can
contain simple wildcards (see sh(1) "File name patterns"), e.g.,
SKIPDIR='editors/openoffice*'.
The variable STARTDIR can hold the path to a starting directory. The
recursion will skip all directories up to that package path. This can be
used to resume a full build at some specific point without having to go
through thousands of directories first.
The variable STARTAFTER can hold the path to a starting directory. The
recursion will skip all directories up to and including that package
path. This can be used to resume a full build after some specific point
without having to go through thousands of directories first.
In case of failure in a subdirectory, the shell fragment held in
REPORT_PROBLEM is executed. Default behavior is to call exit, but this
can be overridden on the command line, e.g., to avoid stopping after each
problem.
$ make REPORT_PROBLEM=true
If REPORT_PROBLEM_LOGFILE is non empty, then REPORT_PROBLEM will default
to:
echo $$subdir ($@) >>$${REPORT_PROBLEM_LOGFILE}
That is, any failure will append the faulty directory name together with
the target that failed to ${REPORT_PROBLEM_LOGFILE} and proceed.
Some targets that do this are all, build, checksum, clean, configure,
extract, fake, fetch, install, distclean, deinstall, reinstall, package,
prepare, show, regress, lib-depends-check, license-check,
all-dir-depends, build-dir-depends, run-dir-depends and generate-readmes.
Target names starting with `_' are private to the ports infrastructure,
should not be invoked directly, and are liable to change without notice.
In the following list, each target will run the preceding targets in
order automatically. That is, build will be run (if necessary) by
install, and so on all the way to fetch. In typical use, one will only
run install explicitly (as normal user, with SUDO defined in
/etc/mk.conf), or build (as user), then install (as root).
fetch Fetch all of the files needed to build this port from the
site(s) listed in SITES. See FETCH_CMD. Use dpb(1) with
option -F to quickly fetch distfiles for a subtree.
checksum Verify that the fetched distfile matches the one the port was
tested against. Defining NO_CHECKSUM to Yes will skip this
step. Sometimes, distfiles change without warning. The main
OpenBSD mirror should still hold a copy of old distfiles,
indexed by checksum. Using
$ make checksum REFETCH=true
will try to get a set of distfiles that match the recorded
checksum.
prepare Install any build dependencies of the current port. Defining
NO_DEPENDS to Yes will skip this step.
extract Expand the distfile into a work directory.
patch Apply any patches that are necessary for the port.
gen Recreate configure machinery if needed, mainly used by GNU
based software that wants autogen/autoconf/automake.
configure Configure the port. Some ports will ask questions during this
stage. See INTERACTIVE and BATCH.
build Build the port. This is the same as calling the all target.
fake Pretend to install the port under a subdirectory of the work
directory.
generate-readmes
Create READMEs and rc scripts under the fake subdirectory.
package Create a binary package from the fake installation. The
package is a .tgz file that can be used to install the port
with pkg_add(1).
install Install the resulting package.
The following targets are not run during the normal install process
(exception clean is run for dependencies with the default settings of
BULK=Auto).
print-build-depends, print-run-depends
Print an ordered list of all the compile and run
dependencies.
clean Remove the expanded source code. This does not recurse to
dependencies unless CLEANDEPENDS is defined to Yes.
distclean Remove the port's distfile(s). This does not recurse to
dependencies.
regress Runs the ports regression tests. Usually needs a completed
build.
reinstall Use this to restore a port after using pkg_delete(1).
update Alternative target to install. Does not install new
packages, but updates existing ones.
LOCK INFRASTRUCTURE
The ports tree can be used concurrently for building several ports at the
same time, thanks to a locking mechanism. By default, locks are stored
under /tmp/portslocks. Defining LOCKDIR will point them elsewhere, or
disable the mechanism if set to an empty value.
All locks will be stored in ${LOCKDIR}. LOCK_CMD should be used to
acquire a lock, and UNLOCK_CMD should be used to release it.
Locks are named ${LOCKDIR}/${FULLPKGNAME}.lock, or
${LOCKDIR}/${DISTFILE}.lock for distfiles fetching.
The default values of LOCK_CMD and UNLOCK_CMD are appropriate for most
uses.
The locking protocol follows a big-lock model: each top-level target in a
port directory will acquire the corresponding lock, complete its job,
then release the lock, e.g., running
$ make build
will acquire the lock, run the port through fetch, checksum, extract,
patch, configure, build, then release the lock. If dependencies are
involved, they will invoke top-level targets in other directories, and
thus acquire some other locks as well.
The infrastructure contains some protection against acquiring the same
lock twice, thus recursive locking is not needed for LOCK_CMD.
Starting with OpenBSD 4.3, the infrastructure supports manual locking:
the targets lock and unlock can be used to acquire and release individual
locks. Both these targets output a shell command that must be used to
update environment variables. Manual locking can be used to protect a
directory against interference by an automated build job, while the user
is looking at or modifying a given port.
UPDATING PACKAGES
Instead of deinstalling each package and rebuilding from scratch, the
ports tree can be used to update installed packages. The update target
will replace an installed package using pkg_add(1) in replacement mode.
If FORCE_UPDATE is set to Yes, dependencies will also be updated first,
and packages will always be updated, even if there is no difference
between the old and the new packages.
Updates use a mechanism similar to bulk cookies and deposit cookies in
the UPDATE_COOKIES_DIR. See the next section for more details, since
most of the fine points of bulk package building also apply to updates.
However, also note that make update is not guaranteed to work, see
CAVEATS below.
BULK PACKAGE BUILDING
Building any significant number of packages from the ports tree should
use dpb(1), a tool located inside the ports tree proper (normally as
/usr/ports/infrastructure/bin/dpb). In particular, it can take advantage
of machine clusters (same architecture and same installation), and of
multi-core machines.
For more detailed information, see bulk(8).
FLAVORS
The OpenBSD ports tree comes with a mechanism called FLAVORS. Thanks to
this mechanism, users can select specific options provided by a given
port.
If a port is "flavored", there should be a terse description of available
flavors in the pkg/DESCR file.
For example, the misc/screen port comes with a flavor called static.
This changes the building process so a statically compiled version of the
program will be built. To avoid confusion with other packages or
flavors, the package name will be extended with a dash-separated list of
the selected flavors.
In this instance, the corresponding package will be called
screen-4.0.2-static.
To see the flavors of a port, use the show target:
$ make show=FLAVORS
To build a port with a specific flavor, just pass FLAVOR in the
environment of the make(1) command:
$ env FLAVOR="static" make package
and of course, use the same settings for the subsequent invocations of
make:
$ env FLAVOR="static" make install
$ env FLAVOR="static" make clean
More than one flavor may be specified:
$ cd /usr/ports/mail/exim
$ env FLAVOR="mysql ldap" make package
Specifying a flavor that does not exist is an error. Additionally, some
ports impose some further restrictions on flavor combinations, when such
combinations do not make sense.
Lots of ports can be built without X11 requirement and accordingly have a
no_x11 flavor.
Flavor settings are not propagated to dependencies. If a specific
combination is needed, careful hand-building of the required set of
packages is still necessary.
MULTI_PACKAGES
The OpenBSD ports tree comes with a mechanism called MULTI_PACKAGES.
This mechanism is used when a larger package is broken down into several
smaller components referred to as subpackages.
If a port is "subpackaged", each subpackage will have a corresponding
description in the pkg/DESCR-subpackage file.
For example, the databases/mariadb port comes with subpackages called
-main, -tests and -server.
In this instance, the build will yield multiple packages, one
corresponding to each subpackage. In the case of our mariadb example,
the packages will be called mariadb-client-<version>,
mariadb-tests-<version>, and mariadb-server-<version>.
To install/deinstall a specific subpackage of a port, you may pkg_add(1)
them manually, or alternatively, you may set SUBPACKAGE in the
environment of the make(1) command during the install/deinstall phase:
$ env SUBPACKAGE="-server" make install
$ env SUBPACKAGE="-server" make deinstall
PORT VARIABLES
These can be changed in the environment, or in /etc/mk.conf for
persistence. They can also be set on make's command line, e.g., make
VAR_FOO=foo
Boolean variables should be set to Yes instead of simply being defined,
for uniformity and future compatibility.
Variable names starting with `_' are private to the ports infrastructure,
should not be changed by the user, and are liable to change without
notice.
PORTS_PRIVSEP If set to `Yes', all operations will happen as restricted
users _pfetch and _pbuild.
PORTSDIR Location of the ports tree (usually /usr/ports).
DISTDIR Where to find/put distfiles, normally
${PORTSDIR}/distfiles.
PACKAGE_REPOSITORY
Used only for the package target; the base directory for
the packages tree, normally ${PORTSDIR}/packages. If this
directory exists, the package tree will be (partially)
constructed.
BULK_COOKIES_DIR
During bulk package building, used to store cookies for
already built packages to avoid rebuilding them, since the
actual working directory will already have been cleaned
out. Defaults to ${PORTSDIR}/bulk/${MACHINE_ARCH}.
UPDATE_COOKIES_DIR
Used to store cookies for package updates, defaults to
${PORTSDIR}/update/${MACHINE_ARCH}. If set to empty, it
will revert to a file under ${WRKDIR}.
LOCALBASE Where to install things in general (usually /usr/local).
SITES Primary sites for distribution files if not found locally.
CLEANDEPENDS If set to Yes, let clean recurse to dependencies.
FETCH_CMD Command to use to fetch files. Normally ftp(1).
FETCH_PACKAGES
If set, try to use as options to pkg_add(1) to install
missing packages from PKG_PATH. bsd.port.mk(5) does not
set FETCH_PACKAGES, so even an empty value amounts to
setting the variable.
For instance, to run pkg_add(1) with default options :
make FETCH_PACKAGES=
or, to use the snapshots directory during the final beta
period:
make FETCH_PACKAGES=-Dsnap
PATCH_DEBUG If defined, display verbose output when applying each
patch.
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.
USING A READ-ONLY PORTS TREE
Select read-write partition(s) that can accommodate working directories,
the distfiles repository, and the built packages. Set WRKOBJDIR,
PACKAGE_REPOSITORY, BULK_COOKIES_DIR, UPDATE_COOKIES_DIR, DISTDIR, and
PLIST_REPOSITORY in /etc/mk.conf accordingly.

HISTORY
The Ports Collection appeared in FreeBSD 1.0. It was introduced in
OpenBSD by Ejovi Nuwere, with much initial effort by Angelos D.
Keromytis. Maintenance passed then to Marco S. Hyman, and then to
Christopher Turan. It is currently managed by Marc Espie, Christian
Weisgerber, along with a host of others found at
[email protected].

CAVEATS
Building a new version of an already installed package is not guaranteed
to work.
The safer way would be to create a sandbox for building the updated port
using proot(1) (see also bulk(8)), and then update the installed package.
Specifically: most software expects building in a virgin environment with
only the required dependency. As a result, lots of time, libraries and
headers under /usr/local will be favored over the currently building
version.
