CCS/TMS320C6678: Make a library

Go through the New Project wizard (CCS menu Project->New CCS Project), expand the "Advanced Settings" and pick "Static Library"" for the Output type. 

During project build, this will invoke the compiler to build the source files and then the archiver to combine the object files into a library. More details about the archiver itself can be found in the C6000 Assembly Language Tools Users Guide.
