Global CXXFLAGS?

Sorry for the dumb question :).

I’ve tried to change the global CXXFLAGS by modifying
gnuradio/configure.ac, but the changes are not propagated to the rest of
the tree even after a configure. I’ve had some success modifying all of
the Makefile.am files in the directories of interest, but is there a
better way?

[The goal would be to force -O0 and -g1, for instance]

Thanks!

I think you should be able to set them using

./configure CXXFLAGS="-O0 -g1" …

Indeed! Thanks.

As a practical matter, we also had to set CCFLAGS, CPPFLAGS, CCASFLAGS,
and FFLAGS. For anyone else out there :).

FWIW, CPPFLAGS shouldn’t contain optimization flags, only stuff like
-I and -D
