I'm working with http://svn.python.org/projects/python/trunk on Mac OS X 10.6.1 using Apples xcode gcc 4.2.1.

When I run the following commands: ./configure --enable-framework --with-universal-archs=32-bit | tee build.config.log make clean all | tee build.make.log I end up with a x8664 Python image. No matter what I use for archs its always the same. I would expect to see -arch arg to GCC but it is not there. export CFLAG="-arch i386" did not work either. Am I doing something wrong or is this broken on trunk? Use: ./configure --enable-framework --enable-universalsdk=/ The --with-universal-archs flag selects whichs architectures should be included when you build a universal binary, defaulting to 32-bit.

The Python default on 10.6 is 64-bit, so wouldn't it be better to default to that on 10.6 and use 32-bit as default on 10.3/4/5 ?!

I'll write some documentation on the build options on OSX, but don't know what's the best location to do so.

Please put that information into Mac/README which already has documentation for how to build universal binaries on Mac.

I guess I should also add logic to configure that bails out when you specifiy --with-universal-archs without asking for a universal build.

That would be useful.
