Installation instructions

Getting pkg_comp up and running is easy, and the process does not require a pre-existing pkgsrc installation. This is intentional given that pkg_comp is intended to simplify interactions with pkgsrc, so cyclic dependencies would be suboptimal.

You can choose to use an installer package, the installer script, source or binary packages for your operating system, or to build from source.

Using the generic installer


curl -L | /bin/sh /dev/stdin

This will fetch and run a script that downloads pkg_comp and its dependencies as source packages, builds all of them, and installs the results under the /usr/local/ prefix. The resulting installation is barebones: i.e. the packages are installed exactly as distributed by the upstream distribution files. No post-install configuration is executed, which means you will have to set everything up by yourself; see pkg_comp(8) to get started.

You will need the pkg-config tool on your system for this to work, but that should be the only necessary dependency.

Using the macOS installer

Download and run the pkg_comp-2.1-20190114-macos.pkg installer. As a prerequisite on macOS, you will also have to download and install OSXFUSE 3.

Read Easy pkgsrc on macOS with pkg_comp 2.0 for a tutorial on this package.

This is a highly-customized installation of pkg_comp intended to simplify the use of pkgsrc on this platform. Because of this, the installer is very prescriptive about the configuration and the location of the installed files. In particular, the package will:

  • Install pkg_comp as /usr/local/sbin/pkg_comp.
  • Place configuration files under /usr/local/etc/pkg_comp/.
  • Create /var/pkg_comp/ to host the pkgsrc tree and the built packages.
  • Default the installation of the built packages to /opt/pkg.
  • Configure a daily cron job, as root, to build a fresh set of packages.

All you need to do to get started is modify /usr/local/etc/pkg_comp/list.txt to indicate which packages you would like built and they will eventually show up under /var/pkg_comp/packages/All/.

You can use /usr/local/libexec/pkg_comp/ to undo the actions performed by this package. The contents of /var/pkg_comp/ will be left behind. Feel free to destroy that directory if you do not need any of the packages you previously built nor the pkgsrc tree.

Using operating-system packages

The following packages are known to exist:

Building from source

Download the pkg_comp-2.1.tar.gz distribution file.

pkg_comp uses the GNU Automake and GNU Autoconf utilities as its build system. These are used only when building the package from the source code tree. If you want to install pkg_comp from a prebuilt package provided by your operating system, you do not need to read this document.

For the impatient:

$ ./configure
$ make
$ make check
Gain root privileges
# make install
Drop root privileges
$ make installcheck

Or alternatively, install as a regular user into your home directory:

$ ./configure --prefix ~/local
$ make
$ make check
$ make install
$ make installcheck


To build and use pkg_comp successfully you need:

  • shtk 1.7 or greater.
  • sandboxctl 1.0 or greater.
  • pkg-config.

Optionally, if you want to build and run the tests (recommended), you need:

  • ATF 0.17 or greater.
  • Kyua 0.6 or greater.

If you are building pkg_comp from the code on the repository, you will also need the following tools:

  • GNU Autoconf.
  • GNU Automake.

Regenerating the build system

This is not necessary if you are building from a formal release distribution file.

On the other hand, if you are building pkg_comp from code extracted from the repository, you must first regenerate the files used by the build system. You will also need to do this if you modify, or any of the other build system files. To do this, simply run:

$ autoreconf -i -s

If ATF and/or shtk are installed in a different prefix than Autoconf, you will also need to tell autoreconf where the ATF and shtk M4 macros are located. Otherwise, the configure script will be incomplete and will show confusing syntax errors mentioning, for example, ATF_CHECK_SH. To fix this, you have to run autoreconf in the following manner, replacing '' and '' with the appropriate path:

$ autoreconf -i -s -I <atf-prefix>/share/aclocal \
  -I <shtk-prefix>/share/aclocal

General build procedure

To build and install the source package, you must follow these steps:

  1. Configure the sources to adapt to your operating system. This is done using the 'configure' script located on the sources' top directory, and it is usually invoked without arguments unless you want to change the installation prefix. More details on this procedure are given on a later section.

  2. Build the sources to generate the binaries and scripts. Simply run 'make' on the sources' top directory after configuring them. No problems should arise.

  3. Install the library by running 'make install'. You may need to become root to issue this step.

  4. Issue any manual installation steps that may be required. These are described later in their own section.

  5. Check that the installed library works by running 'make installcheck'. You do not need to be root to do this.

Configuration flags

The most common, standard flags given to 'configure' are:

  • --prefix=directory Possible values: Any path Default: /usr/local

    Specifies where the library (scripts and all associated files) will be installed.

  • --sysconfdir=directory Possible values: Any path Default: /usr/local/etc

    Specifies where the installed programs will look for configuration files. '/pkg_comp' will be appended to the given path unless PKG_COMP_CONFSUBDIR is redefined as explained later on.

  • --help Shows information about all available flags and exits immediately, without running any configuration tasks.

The following environment variables are specific to pkg_comp's 'configure' script:

  • PKG_COMP_CONFSUBDIR Possible values: empty, a relative path. Default: pkg_comp.

    Specifies the subdirectory of the configuration directory (given by the --sysconfdir argument) under which pkg_comp will search for its configuration files.

The following flags are specific to pkg_comp's 'configure' script:

  • --with-atf Possible values: yes, no, auto. Default: auto.

    Enables usage of ATF to build (and later install) the tests.

    Setting this to 'yes' causes the configure script to look for ATF unconditionally and abort if not found. Setting this to 'auto' lets configure perform the best decision based on availability of ATF. Setting this to 'no' explicitly disables ATF usage.

    When support for tests is enabled, the build process will generate the test programs and will later install them into the tests tree. Running 'make check' or 'make installcheck' from within the source directory will cause these tests to be run with Kyua (assuming it is also installed).

Run the tests!

Lastly, after a successful installation (and assuming you built the sources with support for ATF), you should periodically run the tests from the final location to ensure things remain stable. Do so as follows:

$ kyua test -k /usr/local/tests/pkg_comp/Kyuafile

And if you see any tests fail, do not hesitate to report them in:

Thank you!

You can’t perform that action at this time.
