C++/Wind River Programming

Wind River is a programming environment specifically targeting the cRIO VxWorks OS. The gcc compiler libraries are specifically for FRC.

You can use any text editor and makefiles if you like to write your code, but the compiler and FRC specific headers & libraries are necessary.
