Fair enough, then let's do that. If we go down that road, we'd have to remove BASECFLAGS, OPT and EXTRA_CFLAGS and replace it with the single standard CFLAGS variable, or use an approach similar to the one taken for CPPFLAGS (ie. we allow these extra variables to further customize a CFLAGS setting): CPPFLAGS= @BASECFLAGS@ @OPT@ @EXTRA_CFLAGS@ @CFLAGS@ FWIW, the reason behind the extra variables is not really clear. They only appear to factor out different aspects of the same thing: r38847 | bcannon | 2005-04-25 00:26:38 +0200 (Mon, 25 Apr 2005) | 6 lines Introduced EXTRA_CFLAGS as an environment variable used by the Makefile. Meant to be used for flags that change binary compatibility. r30490 | montanaro | 2003-01-01 21:07:49 +0100 (Wed, 01 Jan 2003) | 10 lines Split OPT make variable into OPT and BASECFLAGS. The latter contains those compiler flags which are necessary to get a clean compile. The former is for user-specified optimizer, debug, trace fiddling. See patch 640843. BTW: I've checked the use of LDFLAGS - this is added to LDSHARED on Mac OS X, FreeBSD, OpenBSD and NetBSD. Perhaps this is something special needed on BSDish system ?! ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1628484> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
