Hi, all,
I'd like to override submake's CPPFLAGS when I run "make debug" at the top
level. I've tried in my top level Makefile, for example:
...
debug:
export CPPFLAGS=-g
$(MAKE) -C subdir
In my sub Makefile, I used this kind of rules:
...
%.o : %.cc
$(CXX) -c $< -o $@ $(CPPFLAGS)
...
I failed to get "-g" to my sub Makefile. Could you point out what might help?
Or what can be an alternative solution?
I've used cygwin and my make is
GNU Make 3.80
