since there were no replies, I went into the various .mk's, and I

The base of the FreeBSD build system, is that SRCS contains file

pathnames. Use .PATH directive if sources are elsewhere. This is the

Hi Mel,
thanks for the clarification. I didn't know that SRCS has to contain
only filenames.
thing you cannot easily change and should not globally change. A
simple
example of this is sbin/fsdb/Makefile which uses sources from sbin/
fsck_ffs.
If you really need it, you should override compilation rules in your
own
BSDmakefile, like so:
.c.o:
${CC} ${CFLAGS} -c ${.IMPSRC} -o ${.TARGET}
.cpp.o:
${CXX} ${CXXFLAGS} -c ${.IMPSRC} -o ${.TARGET}
So, I'm now using only filenames in SRCS and the .PATH target.
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
