I can use operator "+=" to provide additional compile directives, like
CFLAGS += -D_EXTRA_
Is there a way to remove compile directive? Something like this
CFLAGS -= -D_REMOVE_THIS_
I have a source tree being compiled with -O2 option. However, for debugging
purpose, I want all files in one directory to compile without -O2. However,
Makefile in that directly takes CFLAGS from a parent Makefile which I can
not modify !!
Let me know if there a some way to achieve this.
Thanks in advance.
