Hi,

This is a very specific question. I am trying to figure out whether or not
I can use pre-built python libraries and headers on Windows in a MinGW
build on Linux. Essentially I have some python and C++ code which interface
via cython and pybind. I want to build a self contained C++ binary for
Windows with the MinGW compiler that runs on Linux. For both Cython and
PyBind, they need to compile with the python headers and link against the
python DLL in order to run on Windows.

I know that the python DLL specifically are compiled with the MSVC
compiler, however since it is in C, the ABI between the DLL should be
compatible with MinGW, and I should be able to import and link against it.
My question is will this work, or will there be some other problem that I
might run into.

I am using python 3.7 by the way for this.

Let me know what you think,

Thanks :)

Ankit

With the mingw cross-compiler on Linux that should be possible, however
I guess it might be difficult to set it up. Setuptools is not good for
crosscompiling. The easiest way to build Python extensions across
multiple OSes is cibuildwheel: https://github.com/pypa/cibuildwheel

Especially if your code lives on Github, then you can simply add
cibuildwheel to your workflow and it will build for multiple OSes and
Python versions on every commit. For OpenSource projects, Githubs build
servers are even for free! Otherwise, the prices are moderate as well.

If you happen to have your own build server farm (as in a commercial
setting) then you can also use other CI tools with cibuildwheel.
