03/20/2024, 8:07 AMI have a branch for building native exts but mostly using standard tooling. I mentioned it during a meetup but it requires some plumbing from the Pants core side/python backend. At a minimum we can maybe get away with a resolve (for run/pex package) but for distributions we need to know target + py version.

03/20/2024, 8:08 AMI started investigating if we could do that using our existing pyenv tooling but I think it wasn't. Or at least not easy. So would likely need to source the dev-env elsewhere if we don't get it from the host... Which I dislike. :P

03/20/2024, 8:19 AMI think my path to completion here was something like...
• Add zig as a self-contained compiler
• Add py-headers somehow
• Plumb up a c-based module builder
• Implement the same workflow from the Rust repo and ensure it doesn't require any intermediate targets etc
• Profit
