@dpeterson3: Bloodshed Software's Dev-C++ will work great for just learning C++ if that's what you want to do. It
might be possible to compile code for the cRIO with Dev-C++, but it would take a bit of work to get everything set up correctly (changing gcc's target, linking with the vxworks OS libs, etc).
Dev-C++ comes with an IDE and the mingw gcc compiler. You can download it here --
