Its a weird build system. The whole idea here is that .c files can be simply dropped into the build directory and be auto built. I think your notdir thing worked. I tried something similar with pattern substitution using the PWD dir but of course the context switching thing killed me. Ill ping back later to the list with a full solution. Thanks Sam.
