Hey @brainstorm ! Could you tell me if this PR solves the issue for you on an M1 mac?

I tried on an Intel Mac and Linux and it worked, but I don't have an M1 mac unfortunately.

Hey @nmoutschen, thanks for iterating on this!

Unfortunately it does not work on my M1:

So I guess at this point it's either podman:

Or the older Docker workaround you pointed at:

https://github.community/t/why-is-docker-not-installed-on-macos/17017/7

I'd prefer to have it solved natively though (cargo build), but I get it can be tricky to fix up properly... happy to test out things you throw my way in any case ;)

Using cross works for me on archlinux.

I needed to install aarch64-linux-gnu-gcc to compile for arm, but then my OS had a too-recent version of glibc for al2:

/var/task/bootstrap: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by /var/task/bootstrap)
/var/task/bootstrap: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by /var/task/bootstrap)
/var/task/bootstrap: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by /var/task/bootstrap)

Building with cross worked & passed all the tests

Thanks @ScriptSmith ! I'm going to merge this for now, but keep the issue on M1 macs open until I find a way to reproduce/explore this.
