“......无法弄清......的架构类型”。使用gcc编译Python C扩展时遇到问题 [英] "...can't figure out the architecture type of..." problem when compiling Python C-extension with gcc

问题描述

我刚刚从Snow Leopard升级到Lion，并且我不得不更新的旧python c-extension不想正确编译。我真的不知道该在这里做什么。任何人可以帮助我，所以它编译好吗？它在Snow Leopard中编译得很好。

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.

推荐答案

您似乎在使用32位Python 2.7， python.org。由于Xcode 4的变化（10.4u SDK和gcc-4.0的支持下降），在10.7 Lion上使用Python构建C扩展模块并不实际。使用Apple提供的Python 2.7（ /usr/bin/python2.7 ）或者安装 python.org 64位/ 32位安装程序用于2.7.2而不是32位安装程序。

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.
