This doesn't ring a bell. Have you tried compiling babashka on Asahi linux itself from source?
If that also doesn't work, what I would do is the following:

Make an Hello World GraalVM binary in Java. Compile it on Asahi (or other aarch64 linux) and make an issue with GraalVM about it. Also link the issue here.

From the GraalVM Slack:

IIRC binaries built on a system with 4K pages cannot run on systems with 16K pages

But that can probably be fixed using -H:PageSize=

from babashka.

More news: setting -H:PageSize=16K might help since it will work on 4K page size systems too (since 16 is a multiple of 4).

from babashka.

If you running native-image directly on Asahi it should work as it will pick up the right pagesize. I did a couple of GraalVM smoke tests when when the Asahi installer was released a couple months ago, and that worked fine.

Alas during native-image build-time we assume the pagesize to be constant (= the value set via -H:PageSize=) and thus the generated code only works with that pagesize (or smaller). Unlikely that we'll fix that anytime soon, especially because the easy workaround here is to use -H:PageSize=16K.

FWIW, as marcan suggested, the better choice for shipping is -H:PageSize=64K on linux-aarch64. Should be future proofed then 😉

Managed to get to compile and run with

Would make a PR but I guess we need this flag optional based on arch type?

from babashka.

@sitepodmatt I can make a branch so you can test the binary on Asahi. If it works, then we'll keep the flag for linux aarch64.

@borkdude sounds good

@sitepodmatt Here's the link to the binary: https://output.circle-artifacts.com/output/job/046077be-445a-4499-943d-40641c55e411/artifacts/0/release/babashka-1.3.183-SNAPSHOT-linux-aarch64-static.tar.gz

Can you let me know if it works on Asahi?
