.. _compiling: ========= Compiling ========= These instructions are based on Debian 8.0 because it has to be based on something. Other Linux distributions will be similar in the broad ideas but may differ in the specifics. If you already have a preferred distro, use that (we assume you know how to use its package management system). If you don't already have a preferred distro, maybe consider using Debian. First make sure you have a :ref:`copy of the source `. You can either fetch the latest source from git, or download one of our release tarballs. .. Note:: Cyrus does not support compiling with `Link Time Optimization `_, but some platforms now enable Link Time Optimization by default. If your platform does so, you will need to override it, perhaps by adding ``-fno-lto`` to ``CFLAGS`` and ``LDFLAGS``.

If you are building normally from a pure release tarball, then you don't need these dependencies.

Default build: mail only ------------------------ .. parsed-literal:: $ :command:`autoreconf -i` $ :command:`./configure` [options] Check the summary after ``./configure`` completes to ensure it matches your expectations. To view all options, and disable or enable specific features, please see: .. parsed-literal:: # :command:`./configure --help` .. tip:: Passing environment variables as an argument to configure, rather than setting them in the environment before running configure, allows their values to be logged in config.log. This is useful for diagnosing problems. Optional dependencies --------------------- Some features are disabled by default and must be explicitly enabled via configure. Sieve is enabled by default.

It may be of use to also add ``--std=gnu99`` to the ``CFLAGS``. That generates TONS of warnings. Having problems with :ref:`compilation ` or :ref:`linking `? If you're running on Debian, and you install to ``/usr/local``, you may need to update your library loader. Edit ``/etc/ld.so.conf.d/x86_64-linux-gnu.conf`` so it includes the following additional line:: /usr/local/lib/x86_64-linux-gnu Without this, when you attempt to start Cyrus, it reports ``error while loading shared libraries: libcyrus_imap.so.0: cannot open shared object file: No such file or directory`` because it can't find the Cyrus library in /usr/local/lib. Check ----- .. code-block:: bash make check # this runs the cunit tests. This runs the cunit tests and is used for testing that the libraries support all the expected behaviour. If this fails, please :ref:`report it to the cyrus-dev mailing list ` with details of your source version, operating system and affected libraries.
