numpy - 在 Windows 上使用 f2py 构建 64 位 Python 扩展

Question

我正在尝试使用 Numpy 的 f2py.py 从 Fortran 源代码构建 Python 扩展脚本。我正在按照 http://www.scipy.org/F2PY_Windows 中的步骤操作(web archive)。我的系统是Windows 7 64位，我主要使用Python 2.7.3 [MSC v.1500 64位(AMD64)]。我有 Numpy-MKL 1.7.1，来自 http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

这是我尝试过的:

1. 选择 Fortran 编译器。由于我使用的是 64 位 Python，因此需要 64 位 Fortran 编译器。来自 MinGW-w64 ，我尝试了一些个人构建。
2. 打开一个新cmd.exe shell，然后编辑提取 GCC 编译器的路径，即:
   • set PATH=%PATH%;c:\gnu\mingw64\bin
   • set C_INCLUDE_PATH=C:\gnu\mingw64\include

3. 尝试 f2py.py使用此命令构建:

   C:\Python27\python.exe C:\Python27\Scripts\f2py.py -c --fcompiler=gnu95 --compiler=mingw32 -lmsvcr90 -m foo foo.f90

输出为(删除 <--snip--> 处的噪声线):

请注意，第一次运行时，会在C:\Python27\libs中构建三个新文件。 :

• libmsvcr90.a
• libpython27.a
• python27.def

我还需要安装其他东西吗？我需要向 f2py 提供其他选项吗？ ？更一般地说，是否可以从 GNU 编译器构建 MSVC-build Python 的扩展？

看来解决方案就是注释掉异常行。看这个blog post .
