问题


I just upgraded from Snow Leopard to Lion, and an old python c-extension that I had to update didn't want to compile properly. I don't really know what to do here. Anyone who could help me out so it compiles ok? It compiled just fine back in Snow Leopard.

Home:folder Me$ python setup.py build
running build
running build_ext
building 'ccookies' extension

回答1:


You appear to be using a 32-bit Python 2.7, possibly installed from python.org. Because of changes in Xcode 4 (dropping of support for the 10.4u SDK and gcc-4.0) it is not practical to build C extension modules with that Python on 10.7 Lion. Either use the Apple-supplied Python 2.7 (/usr/bin/python2.7) or install the python.org 64-bit/32-bit installer for 2.7.2 instead of the 32-bit-only one.

I was trying to install pynauty on my Mac OS X 10.7 and I got this problem. For some reasons, Ned Deily's answer didn't help me. I just want to provide one more way to solve this problem in case someone come to this page and is in the same situation as I am. The way I solved this prolem is:

Before running "python setup.py build", run: export ARCHFLAGS="-arch x86_64"

On travis, I was getting this error. I've been using osx_image: osx10.11 since forever, but it suddenly stopped working, with this error, in last ~few weeks. Changing to osx_image: xcode7.3 fixed the error for me.
