使用gcc编译Python C-extension时"......无法弄清楚......的架构类型"问题

Question

我刚刚从Snow Leopard升级到Lion,而我必须更新的旧python c扩展程序不想正确编译.我真的不知道该怎么做.任何可以帮助我的人都可以编译好吗？它在Snow Leopard中编译得很好.

您似乎使用的是32位Python 2.7,可能是从python.org安装的.由于Xcode 4的变化(不再支持10.4u SDK和gcc-4.0),在10.7 Lion上使用Python构建C扩展模块是不切实际的.使用Apple提供的Python 2.7(/usr/bin/python2.7)或安装python.org 64位/ 32位安装程序 2.7.2而不是32位安装程序.
