pyo3-build-config
has anis_cross_compiling_from_to
check which returnsfalse
when compiling for 32-bit on 64-bit Windows, but the check doesn't take Windows on Arm into consideration and simply returnsfalse
when bothhost
andtarget
are Windows, resulting in compilation failure when cross-compiling for aarch64 on x86-64 Windows.This PR fixes the check according to the original comment, and
marutin build --target aarch64-pc-windows-msvc
works as expected on x86-64 Windows with MSVC toolchain.Related Issue: PyO3/maturin#2368
I wonder if this PR should be merged with #4773.
