Welcome to Zimbra Open Source!!
First things first let’s set up a development environment. I used a separate box and started from a clean install. Feel free to skip this step if you’ve got an existing Fedora or RHEL 4 install. I did a minimal install of Fedora Core 3. To make things easier disable the firewall and SELinux. Otherwise you may have issues getting the install working. The full source build/install notes have been included below. You can also find this readme in the zcs-src.tgz under ZimbraWebClient/WebRoot/adminhelp/CS/txt/readme_source.txt
If you run into issues or have questions please feel free to ask in our developer forums.
