How to cross compile cython with zig cc

Question

Is there a way to cross compile cython project with zig cc . According to this blog zig can cross compile. An example which cross compiles cython hello world would be great.

Answer 1

You'd need the python headers for the target.

Once you have them, you should be able to run:

# Compile .pyx to .c
cython helloworld.pyx
# Use zig to compile+link
zig build-lib -dynamic -target x86_64-windows \
   -I mingw-w64-x86_64-python/mingw64/include/python3.10/ \
   -lc \
   mingw-w64-x86_64-python/mingw64/bin/libpython3.10.dll \
   helloworld.c
