NOTE: This page is still being updated and the instructions are no longer working as of 2013-04-16 (master has changed quite a bit). Please follow the existing README for the Download area and install OpenSRF/Evergreen from scratch on Ubuntu 12.04 Server or Debian 6.
Evergreen is built on the OpenSRF application framework. If you're interested in implementing new services in Evergreen, or in calling Evergreen APIs (and who wouldn't be?!), you should probably start by reading through the Easing Gently into OpenSRF article to get an overview of how OpenSRF works.
You should also work through this tutorial that focuses on getting up and developing with Evergreen.
We have also documented the norms and processes for contributing to the Evergreen project to help you settle into our community.
To enable you to get hands-on with the code as quickly as possible, the developer virtual image available from http://evergreen-ils.org/downloads/vm/EvergreenMasterSqueeze.ova is current with OpenSRF and Evergreen Master as of 2013-04-15. NOTICE: If you are using this virtual machine, there are a small configuration steps needed.
(as opensrf) cd /openils/var/web/xul ln -s master02102012/ 0master_b324da2
The developer virtual image has a checkout of both OpenSRF and Evergreen's Git repositories, found in the opensrf user's home directory. Detailed instructions for installing are available via each project's README file, or via the example below.
