cross compile to aarch64-musl from x64?

[hidrol]

I have found examples to cross compile from x64 to either musl or arm64. Is it possible to cross compile a statically linked (musl) arm64 binary on an x64 system?

[dpc]

Should be. The problem might be C dependencies (as usual).

[ipetkov]

Yeah there's no theoretical reason why it shouldn't be possible. Have you tried combining the musl and the cross compiling examples?

[hidrol]

yes i have tried to combine both examples, but unfortunately i have not been successful and have not had the time to try again.

Cross-compiling is generally a PITA for reasons unrelated to crane. I have a project wrapping crane that (as part of what it does) handles a lot of xcompiling: https://github.com/rustshop/flakebox

You might want to use it as a source of inspiration.

Also feel free to ping me here or on flakebo's Matrix channel and I can try to help (as time allows). I have a lot of experience getting stuff to cross-compile in Rust and Nix/crane.
