[issue8366] OS X universal builds fail on 2.7b1 and py3k with "Don't know machine value for archs"

[Ronald Oussoren]

Ronald Oussoren <ronaldoussoren at mac.com> added the comment:

This problem is caused by this bit in Makefile.pre.in:

OPT=            @OPT@
BASECFLAGS=     @BASECFLAGS@
CFLAGS=         $(BASECFLAGS) @CFLAGS@ $(OPT) $(EXTRA_CFLAGS)


There both 'BASECFLAGS' and 'CFLAGS' get patched in from configure.in, while the intention of the configure script always was that only BASECFLAGS gets set from configure CFLAGS. 


BTW. I always test with a build directory separate from the source directory, that makes it a lot easier to ensure that you have a clean environment:

$ mkdir build
$ cd build
$ ../configure ....


I'm currently testing a fix that only sets CFLAGS and CPPFLAGS and will apply that if this results in a valid build.


Adding 2.6 and 3.1 to the list of versions because those also have the same change to Makefile.pre.in

----------
versions: +Python 2.6, Python 3.1
