GCC dependency generation for a different output directory

Question

I\'m using GCC to generate a dependency file, but my build rules put the output into a subdirectory. Is there a way to tell GCC to put my subdirectory prefix in the dependency f

Answer 1

Detailing on DGentry's answer, this has worked well for me:

.depend: $(SOURCES)
    $(CC) $(CFLAGS) -MM $(SOURCES) | sed 's|[a-zA-Z0-9_-]*\.o|$(OBJDIR)/&|' > ./.depend

This also works in the case where there is only one dependency file that contains the dependency rules for all source files.
