========================================= Overview of Cyrus development environment ========================================= The pre-requisites ================== While Cyrus itself can be run under many operating systems, we recommend the following operating systems for development, because the dependencies and libraries are known. If you get a development environment working under a different operating system, we'd love to :ref:`hear about it `. * Debian / Ubuntu * Fedora / Redhat The components ============== Source ------ Cyrus IMAPd Can't do anything without this! Follow the :ref:`Cyrus IMAP installation guide `. Cyrus SASL Used for providing user authentication to the mail server. When developing against Cyrus, however, we assume that Cyrus SASL is a third party pre-built component. There is a separate section on compiling from source if you're interested in :ref:`contributing to Cyrus SASL `. Testing tools ------------- Cassandane System test suite for Cyrus IMAPd. The :ref:`Cyrus testing guide ` has instructions for :ref:`installing Cassandane `. Caldav Tester Testing tool for CalDAV and CardDAV.
