Apparently my changes to support 'O=' are quite obsolete: I was not aware
about
the pending patches on http://user-mode-linux.sourceforge.net/patches.html
and about
this mailing list dedicated to the uml development to which I have just
subscribed.
Now I'm aware :->
The second change proposed in my patch concerned USER_OBJS dependences:
I removed specific rules using the generic Kbuild rule just overwriting
'c_flags':
-$(USER_OBJS) : %.o: %.c
- $(CC) $(CFLAGS_$(notdir $@)) $(USER_CFLAGS) -c -o $@ $<
+$(USER_OBJS) : c_flags = -Wp,-MD,$(depfile) $(CFLAGS_$(notdir $@))
$(USER_CFLAGS)
+
I agree that it's not very elegant and robust but it does the job and
could be useful until
Kbuild will provide a clean way to do it.
If you think useful, I may create a patch with this change only.
Should I do it against 2.6.10 as an add-on to the
http://user-mode-linux.sourceforge.net/patches.html
tarball?
That lead me to another question: why we don't use directly BitKeeper? We
could have a repository for uml
development.
