I'm afraid I don't really know what to provide here. I'm a bit lost. Google sends me in entirely irrelevant directions.
I've just upgraded to Python 3.5 and am now trying to get my current project working with it. Unfortunately, part of it is done in Cython, and I've had to spend the last three days trying to get Python to talk to MinGW. Now I've done that via this patch, but the compilation still fails.
This file compiled flawlessly previously, so presumably it's something about the way Cython is set up.
Here's the full text of the command I give and the error message:

Here's setup.py:
from distutils.core import setup from Cython.Build import cythonize import numpy setup(options={'build_ext': {'compiler': 'mingw32'}, "compiler_directives":{"language_level": "3"}}, ext_modules=cythonize("fx.pyx"), include_dirs=[numpy.get_include()]) And finally, here's fx.pyx itself:

I'm sorry for the "here's some text what's wrong with my program" style question but I seriously have no idea what the hell is going on. Can someone point me in the right direction?
