You can try this repo: [koji] name=Fedora 12 - i386 - Just Born baseurl=http://koji.fedoraproject.org/static-repos/dist-f12-build-current/i386 enabled=0 replacing i386 if need be. I'm running Eclipse 3.5 [1] from there with the latest Mylyn. I haven't tried the CDT from that repo. Andrew [1] yum --enablerepo=koji --nogpgcheck install eclipse-pde
