Cython with MinGW-w64

[Stepan Kasal]

Hello,
I routinely compile cython modules for Anaconda on windows x86-64 with mingw w64, for Python 2.7.

I was not able to do the same with Python 3.x.

In both cases, I build the modules through pyximport.
With --verbose, I was able to see the commands and tweak them.

Using Python 3.4, I was able to link xxxx.pyd using -l msvcr100.dll, but the module then did not load.
How can one debud such a situation?  Can I see exported symbols of a dll somehow?  Can I get
more detailed explanation of the reasons why loading the module failed?

Python 3.6 is probably built with MSVC2015, so there is no direct replacement for msvcNN.dll; can that be fixed somehow?

Thank you in advance for any help.

Search for mingwpy. You will find a wheel for installation. This works for me. The official mingw64 produces incompatible dlls.

Thank you for your answer, I will try it.
Can you tell me what version of Python are you using?

Thanks,
Stepan

It work for me as well:
Anaconda 2.2.0 64-bit, without package mingw, but with wheel mingwpy installed from
https://anaconda.org/carlkl/mingwpy

Thank you, Martin, for your help.

FYI mingwpy has no roadmap and no funding for Python 3.5+ due to issues with UCRT in Python 3.5 and 3.6 in MSVC 2015+.
