尝试使用f2py换行时出错（最小工作示例）

标签： python fortran cygwin f2py

我试图运行列出的Minimum working example文件：
https://docs.scipy.org/doc/numpy-dev/f2py/getting-started.html

在Cygwin中运行以下命令

python c:/Python27/Scripts/f2py.py -c fib1.f -m fib1 --compiler=mingw32

该命令退出时出现以下错误：

error: Command "gcc -O2 -Wall -Wstrict-prototypes -DNPY_MINGW_USE_CUSTOM_MSVCR -D__MSVCRT_VERSION__=0x0900 -Ic:\cygwin\tmp\tmprggtye\src.win32-2.7 -IC:\Python27\lib\site-packages\numpy\core\include -IC:\Python27\include -IC:\Python27\PC -c c:\cygwin\tmp\tmprggtye\src.win32-2.7\fib1module.c -o c:\cygwin\tmp\tmprggtye\Release\cygwin\tmp\tmprggtye\src.win32-2.7\fib1module.o" failed with exit status 1

以下是控制台上打印的整个输出：

我已经倾注了大量的链接，试图找到一些无济于事的解决方案 如果有人可以帮我解决这个问题，将不胜感激 我使用的是Windows 7（64位）和Python 2.7.11。

发布我为后人所做的事情
在尝试了评论中提到的内容之后（不记得所有内容），我尝试了以下内容：

python c:/Python27/Scripts/f2py.py -c fib1.f -m fib1 --compiler=msvc --fcompiler==g77

g77是一个现成的fortran编译器（任何其他fortran编译器应该工作）。

我最终遇到了以下错误：

error: Unable to find vcvarsall.bat

为了摆脱最后的错误，我从中获取灵感 1）error: Unable to find vcvarsall.bat
2）How do I point easy_install to vcvarsall.bat?

我将vcvarsall.bat C:/Python27/Lib/distutils/msvc9compiler位find_vcvarsall()的位置硬编码到变量toolsdir和productdir的第245和249行。

我这样做了，因为设置2（上面）中提到的环境变量不起作用。

可能不是一个优雅的解决方案，但它确实有用。
