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 copy of the source. You can either fetch the latest source from git, or download one of our release tarballs.

Build dependencies for additional functionality

The following dependencies enable additional functionality, help with code maintenance tasks or are required for building the documentation.

Developers only

The developer dependencies are required if you are building from git sources, have modified certain source files from the release tarball, or have configured with --enable-maintainer-mode in order to build a new package.

If you are building normally from a pure release tarball, then you don’t need these dependencies. The files, these dependencies produce, have been pre-built and included in the release, and do not normally need to be re-built.

mysql or mariadb

libmysqlclient-dev or libmariadb-dev

mysql-devel or mariadb-devel

yes/no

MariaDB or MySQL development headers, required to allow Cyrus IMAP to use it as the backend for its databases. Configure options: --with-mysql, --with-mysql-incdir, --with-mysql-libdir.

postgresql

no

It provides Brotli compression support for http communications (otherwise only deflate and gzip (optionally) would be available).

libchardet

libchardet-dev

libchardet-devel

yes/no

It is used by the JMAP module of httpd to detect the character set of untagged 8-bit headers. Without it, cyrus-imapd will not do character-set detection. If some piece of data has no character set coming in, it will have no character set. Required for JMAP, but otherwise is not needed.

libical

libical-dev

libical-devel

yes

It provides calendaring functionality for CalDAV, which can’t be used without this lib. Version 3.0.0 or higher is required.

libxml

libxml2-devel

yes

A fundamental lib for all *DAV functionality.

nghttp2

libnghttp2-dev

libnghttp2-devel

no

HTTP/2 support for the entire httpd subsystem (*DAV & JMAP).

shapelib

shapelib

shapelib

yes/no

It is required for tzdist service to have geolocation support. Otherwise it is not needed. Version 1.3.0 or higher is required when using it.

wslay

libwslay-dev

wslay-devel

no

It provides WebSockets support in httpd. Only used with JMAP, otherwise not needed. Version 1.1.1 or higher is required when using it.

no

It is used by cyr_virusscan, otherwise not needed.

PCRE 1 (8.x) - for utf-8/unicode regular expression matching. Could be replaced by something else in the future. See issues/1731 for more information.

perl(Term::ReadLine)

no

Perl library needed by cyradm.

libsrs2

no package

no package

no

It is used for implementing Sender Rewriting Scheme (SRS) functionality for messages forwarded by sieve scripts. Without it, messages forwarded by sieve scripts will not have this functionality and might have difficulty delivering to SMTP servers that insist on it.

Install tools for building
  • sudo apt-get install build-essential

Optionally install dependencies for building the docs.
  • sudo pip install python-sphinx

  • sudo cpan install Pod::POM::View::Restructured

Compile Cyrus

There are additional compile and installation steps if you are using Xapian for searching, or if you are using jmap.

Default build: mail only

$ autoreconf -i
$ ./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:

# ./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.

CalDAV, CardDAV, WebDAV, JMAP

./configure --enable-http --enable-calalarmd --enable-jmap

Murder

./configure --enable-murder

Replication

./configure --enable-replication

Compile

cd /path/to/cyrus-imapd

autoreconf -i -s   # generates a configure script, and its various dependencies

./configure CFLAGS="-W -Wno-unused-parameter -g -O0 -Wall -Wextra -Werror -fPIC" \
--enable-coverage --enable-calalarmd --enable-autocreate \
--enable-nntp --enable-http --enable-unit-tests \
--enable-replication --with-openssl=yes --enable-murder \
--enable-idled --prefix=/usr/cyrus

make lex-fix   # you need this if compile fails with errors from sieve/sieve.c

make

The --prefix option sets where Cyrus is installed to.

It may be of use to also add --std=gnu99 to the CFLAGS. That generates TONS of warnings.

Having problems with compilation or 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

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 report it to the cyrus-dev mailing list with details of your source version, operating system and affected libraries.

Next: installing Cyrus.
