Macos Cython在Mac OS X 10.8上编译/链接失败

我是python的新手，试着用一个建立在 cython文件名为c1.pyx

然后运行cythonc1.pyx，一切正常。 然后运行

gcc-c-fPIC-I/usr/include/python2.7/c1.c

，也很好。 但是运行

gcc-shared c1.o-oc1.so

，它没有通过

有人能解释一下吗

以下是错误消息：

您必须在链接器命令行中包含

-lpython2.7

（或您正在使用的任何Python版本）

不过，使用Cython最简单的方法是使用distutils设置脚本，因为它将为您执行所有的基本编译器命令

谢谢，它已正确编译，但仍存在运行时错误。不管怎样，我按照你的建议继续使用distutils，效果很好。
