Question

我正在尝试安装Python扩展（hydroclimpy.sourceforge.net），它显然需要在安装之前编译一些Fortran。当我为扩展运行build命令时，我最终得到一个错误，告诉我没有找到合适的Fortran编译器：

我的机器是带有Cygwin的Windows XP盒子。已安装Setuptools。我已经安装了g95以及我在Cygwin的安装列表中找到的任何其他东西，它看起来与Fortran相关。 / 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，我可以试着让这台机器上的Fortran情况整理出来，使得这个扩展的安装脚本按预期工作吗？

如果有帮助，此扩展程序的安装脚本位于：

Answer 1

来自不同倾向的替代建议：避免像cygwin这样的问题的一种方法，并尝试在XP机器上获得类似环境的* nix就是采取行动并使用linux。有很多方法可以做到这一点，包括双启动，现场Linux，或者只是去做吧。

Answer 2

您可能想尝试在this python bug中应用补丁，这样我就可以在遇到您描述的完全相同的错误后从源代码构建numpy。

注意：我正在使用VS2010进行编译，你也应该为所有的python扩展使用它。

如何在Cygwin中找不到合适的Fortran编译器来修复这个失败的Python扩展构建？
