hmm, how about if i do this then...
$(SUBDIRS):
ifeq($(ARCH),LINUX)
export MYVAR = DEBUG
endif
cd $@ && $(MAKE)
that doesn't work either. make says "commands commence before first target".
what am i doing wrong? the make syntax is not tabbed, only the command is...
on another note, how would one do a recursive make clean without using a shell
for loop? right now i have it like this:
clean:
@for d in $(SUBDIRS); do \
cd $dd && $(MAKE) clean || exit 1; \
done
but what is the "correct" way to do this?
thank for the help.
