I'm building a workspace that will ultimately build about a dozen or so Linux shared objects (dynamic libraries).
Up until this morning, I'd added the code for four of the project branches. Three of them were C++ projects (using the g++ compiler) and one was a C project (using gcc).
This morning I added a fifth project which was also a C++ project. Since adding this fifth project, none of the C++ branches will compile properly. If I activate a particular branch and select 'Rebuild (CTRL+F11)' only the first source file (for that particular branch) gets compiled - then I get a message saying "g++ no input files. Process terminated with status 1 (0 minutes 0 seconds)". The (one & only) 'C' branch still compiles correctly.
I've tried re-booting in case g++ had somehow got itself locked up but it's no different. Has anyone else ever seen a problem like this???
