f2py 与你好世界
f2py with hello world
我正在尝试学习如何使用 f2py 在 python 中编译 Fortran 代码。我正在使用 Python 2.7.10（通过 Python (x,y)）和 Mingw32 作为我的编译器。我试图让它在 64 位 Windows 7 中工作，但是 Python 2.7.10 在 32 位中是 运行。我将 C:\MingW\bin\ 和 C:\Python27\ 的适当路径添加到我系统的 PATH 文件中。
当我尝试编译一个简单的 hello.f "Hello, World!" 程序时，出现以下错误：

有人可以帮我弄清楚为什么这没有编译并帮助我让它工作吗？
实际上这似乎是 a bug in Python 2.7.10, with 32bit libpython27.a containing 64-bit objects. To fix it, either downgrade python to 2.7.9, or upgrade it to 2.7.11 (or you can follow the route from 问题，但根据您的经验，这可能会很痛苦）。
