I changed this
%.o: %.cpp %.h
$(CC) $(DEFINED)
-c $(INCLUDES) $< -o $@
to this
%.o: %.cpp
$(CC) $(DEFINED)
-c $(INCLUDES) $< -o $@
The %.h dependency made automake search for the .h files in the current directory... Although this worked with the old Makefiles (non Automake).
The $(DEFINED) flag is a bunch of -D preprocessor flags. Is there a way to let automake do the compilation of the various .o files using these flags but without specifying the explicit rule?
Thanks for the various tips Simon , I understand Automake better now :)
