Use --zig in CI?

[kevinheavey]

Hey! I like your CI workflow so I copy it quite closely in my projects 😅

I'm curious: do you think you'll use the new feature to cross-compile with Zig? I don't really understand it but I'm guessing you understand it

Thanks for the suggestion, I'm interested in making an example workflow that cross-compiles with Zig.

I've added --zig support in maturin-action: PyO3/maturin-action#27 , the usage is quite simple:

diff --git a/.github/workflows/CI.yml b/.github/workflows/CI.yml
index e8b2931..60294f6 100644
--- a/.github/workflows/CI.yml
+++ b/.github/workflows/CI.yml

       with:
         target: ${{ matrix.target }}
         manylinux: auto

     - uses: uraimo/[email protected]
       if: matrix.target != 'ppc64'
       name: Install built wheel

It works for cross compiling to aarch64, but other architectures doesn't not work right now mostly due to ziglang/zig#4911. So currently it's not ready to replace Docker.

As of today, with zig 0.10 and maturin 0.14, only s390x fails: https://github.com/messense/rjieba-py/actions/runs/3801172545/jobs/6465356959

maturin-action now fallbacks to docker when --zig isn't supported, so it mostly works now: https://github.com/messense/rjieba-py/actions/runs/4083633467
