Compiling with cython and mingw produces gcc: error: unrecognized command line option '-mno-cygwin'

It sounds like GCC 4.7.0 has finally removed the deprecated -mno-cygwin option, but distutils has not yet caught up with it. Either install a slightly older version of MinGW, or edit distutils\cygwinccompiler.py in your Python directory to remove all instances of -mno-cygwin .

Thanks Ignacio. I already tried this solution by myself (to eliminate -mno-cygwin from cygwinccompyler). The error disappeared but then I got a different error with ld. But this is a different question. I will post it tomorrow. Now need some rest... why is so difficult to compile in windows? – joaquin May 17 '11 at 20:54

We are working on a patch for distutils: bugs.python.org/issue12641 – Éric Araujo Oct 7 '11 at 17:16
