python - Cython 无法在 Windows 7 x64 上编译

Question

我正在努力在 Windows 7 x64 上安装 Cython。我下载并安装了 Automated MinGW 安装程序。为 distutils 文件夹创建了一个 distutils.cfg，内容如下:

[build]
compiler = mingw32

将 C:\MinGW\bin 添加到环境变量后，我调用了 easy_install Cython 但出现以下错误。强奸互联网并没有给我带来有用的结果，因为所有这些编译的东西(或者我应该说 sh*t ？) 对我来说太新了。

任何想法出了什么问题？谢谢!

更新:我使用 dlltools 创建了 libpython27.a，然后再次尝试构建 Cython，它运行良好!但是现在，调用 cython.exe 会出现此错误:

ImportError: DLL load failed, %1 is not a valid Win32-executable.

我假设这是因为我使用 Pythonx64 而不是 MinGW32 编译器？那么，我如何为 x64 编译它？

有预编译的Cython包on this site .我建议您切换到 x86 Python，使用 x64 版本并没有真正的优势。如果您想坚持使用 x64，则不能使用 MingW，而必须使用 MS SDK C++ 编译器 (more on this)。

Do not use MinGW-w64. As you will notice, the MinGW import library for Python (e.g. libpython27.a) is omitted from the AMD64 version of Python. This is deliberate. Do not try to make one using dlltool. [...] There have also been issues with the mingw runtime conflicting with the MSVC runtime; this can happen from places you don't expect, such as inside runtime libraries for g++ or gfortran.
