[Numpy-discussion] Build fortran extension on Windows with gfortran and MSVC

[Marek Wojciechowski]

Hi!

It seems that on Windows + Python-3.5 fortran extensions cannot be built
anymore with f2py and mingw32 compilers, because of new MSVC. Here is the
short description of the errors one gets:

This is sad, because this worked quite nicely with all previous python
versions. I'm curious what are the options now? Is this going to be supported
in the future, with mingw-w64 for example?

Off-topic, but this is something that I get asked quite often, and I don't
know what to say, not being a windows user:
Is there some "howto" compile f2py fortran modules from scratch in windows
with anaconda available?

After installing mingw (conda install mingw), you should go like on Linux. I
think f2py is choosing --compiler=mingw32 by default.

I found that the effort is on the way: http://mingwpy.github.io. The roadmap is
quite ambitious...
