我正在尝试使用Numpy的f2py.py
脚本从Fortran源代码构建Python扩展。我按照http://www.scipy.org/F2PY_Windows (网络档案馆)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 bit (AMD64)]。我安装了来自http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy的Numpy-MKL 1.7.1。
这是我尝试过的:
- 选择Fortran编译器。由于我使用的是64位Python,所以需要使用64位Fortran编译器。我已经尝试了一些个人构建版本,来自MinGW-w64。
- 打开一个新的
cmd.exe
shell,并编辑路径到我提取GCC编译器的位置,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(删除<--snip-->

请注意第一次运行时会在C:\Python27\libs
中生成三个新文件:
libmsvcr90.a
libpython27.a
python27.def
我需要安装其他东西吗?我需要为f2py
提供其他选项吗?更普遍地说,是否可以使用GNU编译器构建MSVC-build Python的扩展程序?
libmsvcr90.a
