Is this excepted on Windows?

My guess is that it is coming from skbuild not python.
Ask would ask them why this happens.
Thanks for your reply! I first created an issue in skbuild but later I found it more possibly related to CPython itself.
I’ve found a workaround, which is not to define
Py_BUILD_CORE globally, instead just define it before including internal headers, and the error gone:
But it’s still not clear how this change affects the linker to me.

Becuase the Windows build has a bug in it?
Why don’t you want to ask the people that wrote skbuild for help?
