Cython构建无法找到C++ 11 STL文件 - 但仅在从setup.py调用时才能找到

Question

当我从setup.py编译我的代码时,它找不到C++ 11包含文件<array>- 但C++ 11编译器功能确实有效.

当我将setup.py生成的相同命令行粘贴到我的shell中时,它完全编译得很好(!)

可以在此处看到演示此行为的代码,并在下面粘贴.

simple.h:

    return x;

#include <string>  // works, so must find some STL.
#include <array>   // fails!

我相信这是我之前有同样的问题在这里.在我的例子中,问题似乎是setuptools使用与Python解释器编译时相同的编译器标志,并且这些标志包含一个标志,使得代码与相当旧版本的Mac OS X兼容(远在C之前) ++ 11).

尝试在您的标记中添加标记-mmacosx-version-min=10.9(或更高版本).extra_compile_argssetup.py
