    Hi Nikhil,

    this seems to be a problem with your linker file search paths/path variables.  Ie your include settings.

    Please see this wiki and double check that the path being complained about (/drivers it seems)  is properly included and keep us informed how it goes.

    http://processors.wiki.ti.com/index.php/Include_paths_and_options

    Best Regards,

    LIsa

    Nikhil,

    The undefined symbol errors are due to missing libraries. These symbols are defined in driverlib, grlib etc in Stellarisware, hence need to be linked in to the project so the references to those symbols can be resolved. If you go into Project Properties->C/C++ Build->TMS470 Linker->File Search Path, you can add the driverlib (and if needed grlib) under the --library option. For additional reference, take a look at one of the Stellarisware example projects, most of them should have these libraries specified.
