Feature

I would like wasmtime releases to be built for musllinux on aarch64 platform.

Benefit

Improved portability of wasmtime-py when installed from PyPI (https://github.com/bytecodealliance/wasmtime-py/issues/263).

Implementation

As far as I know this target should build fine, so only CI scripts need to be updated.

I think it's definitely fine to add this, but it will require someone to figure out how to write a build container for it. For x64 I was able to be "just dangerous enough" to cobble something together, but I've never personally successfully cross-compiled from an x64 system to aarch64-musl. Something like cross may work though perhaps? (we notably want dynamically linked artifacts which is distinct from the default I believe for the Rust target)

Ah, that is a little cursed. I'm supposed to be on vacation right now so I think I'll avoid doing a CI modification this complex :see_no_evil:

Looks like cross does support aarch64 musl, so I'm attempting to integrate using that image in https://github.com/bytecodealliance/wasmtime/pull/9885.

Would you happen to have an aarch64-musl system you can test on? I don't have one myself outside of possibly setting up QEMU.

I do!

Do you have an Android phone? If you set up Termux, it will give you such a system (unless it's really ancient). You get a normal musllinux system.

Doesn't Termux use Bionic like the rest of Android?

It does. Turns out I completely misunderstood how it works! But fortunately it also has proot which still lets you do whichever distro you like.

It does. Turns out I completely misunderstood how it works! But fortunately it also has proot which still lets you do whichever distro (and libc) you like on native aarch64.
