The documentation for the source install of Zimbra is spartan. The documentation in ZimbraWebClient/WebRoot/adminhelp/txt/readme_source.txt is not telling the whole truth. If the system where I am trying to compile Zimbra is not one of the supported systems (aka: RedHat, SuSE, Mandriva, OSX, etc) then the installation will not work and complain about not being able to load ZimbraBuild/defs/UNKNOWN.def.
Is there anywhere a documentation describing how to port the build system to another (unsupported) system?
I know that I can read the source and look my self to get a unsupported build system being recognized but maybe there is already a document describing what needs to be made to get the job done. Does any one know anything about such a documentation? Or does any one here has already taken the hard road to customize the build system to be able to build Zimbra on Gentoo Linux?
