Warnings when building/linking the Python module due to different linker architecture

[bennylp]

Warnings similar to the following may occur on MacOS X when building the Python module:

ld: warning: ignoring file ../lib/libpjsua-x86_64-apple-darwin11.4.2.a, file was built for archive which is not the architecture being linked (i386): ../libpjsua-x86_64-apple-darwin11.4.2.a

ld: warning: ignoring file /Users/bennylp/Desktop/project/pjsip/2.x/pjmedia/lib/libpjmedia-x86_64-apple-darwin11.4.2.a, file was built for archive which is not the architecture being linked (i386): /Users/bennylp/Desktop/project/pjsip/2.x/pjmedia/lib/libpjmedia-x86_64-apple-darwin11.4.2.a

...

These warnings can just be ignored because the module will still be built for the available architecture (x86_64 in this case).

If you want to get rid of the warnings, you can set the ARCHFLAGS to include only architecture that you want to build as follows:

 $ ARCHFLAGS='-arch x86_64' python setup.py build
