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.
Setting up dependencies¶
Required Build Dependencies¶
Building a basic Cyrus that can send and receive email: the minimum libraries required to build a functional cyrus-imapd.
|ICU||libicu-dev||libicu-devel||version 55 or newer|
|openssl (Note about versions)||libssl-dev||openssl-devel|
To install all dependencies from packages on Debian Jessie, use this:
sudo apt-get install git build-essential autoconf automake libtool \ pkg-config bison flex libssl-dev libjansson-dev libxml2-dev \ libsqlite3-dev libical-dev libsasl2-dev libpcre3-dev uuid-dev \ libicu-dev sudo apt-get -t jessie-backports install libxapian-dev
Build dependencies for additional functionality¶
The following dependencies enable additional functionality, help with code maintenance tasks or are required for building the documentation.
The developer dependencies are required if you are building from git sources,
have modified certain source files from the release tarball, or have configured
--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.
|perl-devel||perl-dev||perl-devel||no||Needed for building binary perl libraries, version 5+.|

development headers, required to allow Cyrus IMAP to use it as the backend
for its databases. Configure option:
CalDAV, CardDAV, or JMAP (httpd subsystem)¶
|libbrotli||libbrotli-dev||brotli-devel||no||It provides Brotli
compression support for http communications (otherwise only
|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-dev||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.|
|zlib||zlib1g-dev||zlib-devel||no||It provides gzip compression support for http communications.|
|CUnit||libcunit1-dev||cunit-devel||no||Development headers for

|CLD2||libcld2-dev||cld2-devel||yes/no||Compact Language Detector 2
(probabilistically detects over 80 languages in Unicode UTF-8 text, either
plain text or HTML/XML). Required for Xapian (
to enable ptloader to interface with LDAP directly, for canonification
of login usernames to mailbox names, and verification of login usernames,
ACL subjects and group membership. Configure option:
|pcre||libpcre3-dev||pcre-devel||yes||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
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
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.
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
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
--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
it includes the following additional line:
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.
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.
