In CCS3.3, I want to set include search path in project->build options ->comiler->preprocessor by means of the relative directory. Now the absolute directory of .pjt file is ” D:\pos_28335”,i.e. current directory. And the absolute directory of .h(header file) is “D:\pos_28335\DSP2833x_common\include”. Then how do I set include search path in project->build options ->comiler->preprocessor by means of the relative directory? I doubt whether “.\” means the current directory. But I set the include search path as “DSP2833x_common\ include” and the ccs3.3 can’t find the header file. How to do correctly ? Thanks for your help.
