Hi,

Sorry to hear you are having trouble with GNU make.  I use it very
successfully in situations you describe.  First of all you did not
mention which directory your makefiles and dependency files exist nor
did you mention from which directory you actually type "gmake".

I generally type "gmake" from the obj directory in your example.
In addition my dependencies have the full, relative path of the
C and H files in it.  On occasion I even use the VPATH directive to tell
gmake where to look for stuff.

Matthew
