Hi, The problem continues.
it compiles without error once I delete all the generated files, but the next time (even with 'make clean all' I get the same error from make: "make": *** No rule to make target `c\:\avr-gcc\avr\include\avr\io.h', needed by `MIXER-72x75-0920.o'. Stop. Again, this is probably because of the invalid path above (c\;\...) but i cant figure out the source of this invalid path. Could someone kindly shed some light on this? Thanks!
