我正在尝试使用 Numpy 的f2py.py
脚本从 Fortran 源代码构建 Python 扩展。我正在按照http://www.scipy.org/F2PY_Windows(网络存档)中的步骤进行操作。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:
- 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。从MinGW-w64,我尝试了一些个人构建。
- 打开一个新的
cmd.exe
shell,并编辑我提取 GCC 编译器的路径,即:set PATH=%PATH%;c:\gnu\mingw64\bin
set C_INCLUDE_PATH=C:\gnu\mingw64\include
使用以下命令尝试
f2py.py
构建:C:\Python27\python.exe C:\Python27\Scripts\f2py.py -c --fcompiler=gnu95 --compiler=mingw32 -lmsvcr90 -m foo foo.f90
输出为(去除 处的噪声线<--snip-->

请注意,第一次运行时,会生成三个新文件C:\Python27\libs
:
libmsvcr90.a
libpython27.a
python27.def
我需要安装其他东西吗?我需要提供其他选项f2py
吗?更一般地说,是否可以从 GNU 编译器为 MSVC 构建 Python 构建扩展?
