As I described in my initial mail, I have to use two makefiles. One is the main Makefile, while the other has to be generated. In the generated .mk, I add to the SRCS, and I create the .PATH target with other (necessary) directories. Unfortunately, make depend doesn't work as it should be. This is the important snippet of my BSDmakefile: ---8<--- elements.mk: elements.conf $(CLICKDIR)/click-buildtool elem2make --bsd elements.conf > elements.mk .MAKEFILEDEPS: elements.mk .sinclude "elements.mk" .include <bsd.kmod.mk> --->8--- When I run make depend, it only includes SRCSs from BSDmakefile, not those from elements.mk. Is there a way to overcome this? I can manually run make elements.mk, but it is a bit tedious. Cheers, Nikola
