如何让 setup.py test 使用特定的 fortran 编译器？

Question

我正在尝试测试包含一些 f90 文件的package。如果我构建或安装并指定 fortran 编译器，它工作正常。但是，当我尝试测试时，出现以下错误：

有没有办法解决这个问题？我在 Windows 7、python 2.6、numpy 1.4.1 上。

Answer 1

我认为问题在于“测试”命令需要就地构建。

python setup.py config --fcompiler=gfortran build_ext --inplace

产生了和以前一样的错误，但是

python setup.py config --fcompiler=gfortran build_ext

不是。

我能够解决这个问题

1. 以交互方式运行设置 模式（python setup.py）

2. 将 fortran 编译器设置为 gfortran

3. 选择就地构建 (3)

Answer 2

该软件包的documentation 建议按如下方式构建：

python setup.py config --compiler=mingw32 build --compiler=mingw32 install

这应该适用于 mingw32 版本的 gfortran。我没有可访问的 Windows 机器，但是当我使用 gfortran 构建其他 Python 模块（例如 numpy）时，命令类似于：

python setup.py build --fcompiler=gnu95

ETA：我误读了您问题的开头，现在我看到您可以构建但不能测试。你试过只用“--compiler=mingw32”吗？
