如何让setup.py测试使用特定的Fortran编译器？
我正在尝试测试一个包含一些f90文件的包。如果我指定Fortran编译器进行构建或安装，它就能正常工作。但是，当我尝试测试时，出现了以下错误：

有没有办法解决这个问题？我使用的是Windows 7，Python 2.6，NumPy 1.4.1。

这个文档对这个软件包的构建方式有推荐：
python setup.py config --compiler=mingw32 build --compiler=mingw32 install
这个方法应该适用于mingw32版本的gfortran。我没有办法使用Windows机器，但我之前用gfortran构建其他Python模块（比如numpy）时，命令大概是这样的：
python setup.py build --fcompiler=gnu95
补充说明：我刚才看错了你的问题开头，现在我明白你是可以构建但不能测试。你试过只用“--compiler=mingw32”这个选项吗？

我觉得问题出在'test'命令需要在原地构建。
python setup.py config --fcompiler=gfortran build_ext --inplace
之前的错误还是出现了，但
python setup.py config --fcompiler=gfortran build_ext
这个错误没有出现。
我找到了解决这个问题的方法：
以交互模式运行设置（也就是用python setup.py）
把Fortran编译器设置为gfortran
选择原地构建（选项3）
