MinGW & building wheels

[Scott Talbert]

Hi all,

Does anyone have any experience with using Fedora's MinGW stack to 
cross-compile Python wheels for Windows?

I'm using the mingw stack to cross-compile a Windows binary which shipped as 
part of an otherwise platform neutral Python wheel. The main problem I had 
with Fedora's mingw Python was that I could not create a Windows wheel.

Yep, that's the same thing I'm trying to figure out.  The compiling part 
works fine - it's the mechanics of cross-building a wheel that don't seem 
as clear.

I figured I needed to run the mingw Python (with wine) to get an actual 
Windows wheel. That part would require a virtualenv for my package.

However I can avoid that problem alltogether as my wheel just needs to contain 
an exe file (as "data") so I can use the Linux Python 3 to create a 
platform-neutral wheel.

I think the venv part would require some more serious patching in Fedora (and 
I would love to see this but unfortunately I can't spend time getting this fixed).
