Has anybody tried to build a NIF for windows from zig? I’ve tried some simple example like here and it compiles fine for linux but fails for windows.

erlang 26.0.2
erts 14.0.2
zig build -Doptimize=ReleaseSafe -Dtarget=x86_64-windows-gnu -Dcpu=x86_64+avx2+fma+f16c

Not sure what this problem is exactly, but with that target (…-gnu) you will definitely run into problems later as stock Erlang is compiled with MSVC, Been there :slight_smile:
