Re: Override CFLAGS when using cdbs

Which I learned by this example and which makes me wonder whether
there is absolutely no way out to enforce overriding CFLAGS.
I suggest you either try to set -I for the whole build or
This makes no real sense because it concerns a relative path to
a subdirectory in the source tree that does not exist from
every subtree location.
change the upstream build to use its internal CFLAGS and still honor
"user" (that's you) provided CFLAGS. For an explanation on why the
upstream build should honor CFLAGS but not use them, see:
<http://sourceware.org/automake/automake.html#User-Variables>.
Well, the project does not use automake and thus I can not
reasonably use this option. I think one reasonable way would
be to unset CFLAGS for cdbs (well, CFLAGS_<package>="" is in
fact not unsetting it, because it just get's a new value but
it is defined and overrides the upstream setting) and use
a MYCFLAGS instead that I can append to the upstream CFLAGS
later on when needed. Unfortunately I have not found a way
to prevent cdbs from defining CFLAGS.
Moreover I'm really amazed that there is no way force replacement
of CFLAGS inside a Makefile once it is setted outside. I would
call this an insane constraint of make.
For instance I also tried
CFLAGS:=$(if $(CFLAGS),"$(CFLAGS) -I$(INCLUDEDIR)","-I$(INCLUDEDIR)")
which also did not show any effect.
Kind regards
Andreas.
