Hi,
I have a not so complex Makefile which first generates and
includes a Makefile.subdirs (which contains a variable SUBDIRS
with a list of directories) and then I'd like it to execute
a depend and a compilation phase (that one in every subdir).
The Makefile.subdirs generation and depend work fine, but
I never see gmake descending into the $(SUBDIRS) and it reports
"nothing to be done for all" even though I've put the $(SUBDIRS)
under the .PHONY target.
Does anybody see, what am I doing wrong or should I come up
with a simpler test case? Thank you for any hints.
Regards
Alex
