whenever i try to use API for eg GPIOPINREAD and compile i get errors like gpiopinreadundefined.../unreferenced even after puting all the necessary driver lib and header files.
Must be a problem with the path. Have you given the path addresses properly in your project settings and the code?

Are you sure that you are including both the headers and the actual library...?
Much of this pain/suffering can be prevented by simply copying one of the known good projects w/in your MCU-specific StellarisWare. Store this original file in a different directory - so it is not over-written. Beauty of this method - especially if you've chosen a project which includes many of the functions you require - is that the required file linkages are proper. Inevitably - new users seem "compelled" to "create their own" projects - and then bump into the "joy" of a too-complex IDE.
Sticking with existing projects is an effective defense...
