Yeah so one thing that's unique about eclipse is the error/warnings sometimes tend to stick around even after you resolve and rebuild. I'm guessing that was the first problem.

That new error sounds like a genuine compiler error, so that means the linker isn't able to create FRCUserProgram. Probably should confirm that though. That also means that you haven't actually been successfully building this whole time, which is good to know.

That line with the Talon c'tor error probably has been a problem this whole time and now it's revealing itself. Maybe make a simple project first and merge in your stuff in pieces until the error shows up to see what the cause is.

Alan's right, the problem is likely before that line, could be in one of the headers too.
