python - 由于在 Cygwin 中找不到合适的 Fortran 编译器，我该如何解决这个失败的 Python 扩展构建？

Question

我正在尝试安装一个 Python 扩展 (hydroclimpy.sourceforge.net)，它显然需要在安装之前将一些 Fortran 语言编译到自身中。当我运行扩展的构建命令时，我得到一个错误，告诉我没有找到合适的 Fortran 编译器:

我的机器是装有 Cygwin 的 Windows XP 机器。安装工具已安装。我已经安装了 g95 以及我在 Cygwin 安装列表中找到的任何其他看起来与 Fortran 相关的东西。/usr/local/bin 显示 g95 和 gfortran:

$ ls -l /usr/local/bin/
total 159
lrwxrwxrwx 1 James None     52 Nov 13 14:07 cc1 -> /usr/local/lib/gcc-lib/i686-pc-cygwin/4.1.2/f951.

-rwxr-xr-x 1 James None 158895 Nov 13 14:07 i686-pc-cygwin-g95.exe

任何人都可以提出其他建议，我可以尝试以某种方式解决这台机器上的 Fortran 情况，使此扩展的安装脚本按预期工作吗？

如果有帮助，这里是此扩展的设置脚本:

来自不同角度的替代建议:避免像 cygwin 这样的问题，并尝试在 XP 机器上获得类似 *nix 的环境的一种方法是尝试使用 linux。有很多方法可以做到这一点，包括双启动、live linux，或者直接去做。
