hey all,
I'm surpised this is not a FAQ, but what I'm trying to do is to add to an
existing makefile variable, ie:
make CFLAGS+=-g
Unfortunately, this doesn't seem to do what I intend, namely looking in the
makefile and extracting the CFLAGS variable, and then appending '-g' to it.
Instead, it looks in the *environment* to find a CFLAGS. Which is pretty
useless because most packages take their CFLAGS variable from a line in a make
file.
How do you 'reach in and grab' a makefile variable, and then add to it?
Ed
