My C++ project is now in Fedora Eclipse (Version: 3.4.1 Based on build id:  20080911-1700) and the perennial question comes up…

Q: What files am I required to checkin to version control (SVN)?
A: .cproject and .project

If you are testing the checkin on your machine there is one caveat. Delete the project from the Project Explorer. Then use the Import command from the File menu. This process will create some of the temporary files that were not checked-in but expected to be there when building the project.
