Support for aarch64/raspberry-pi

[matthiasdotsh]

Thank you very much for this fantastic package. I discovered it yesterday, and I successfully packaged my own derivation as an AppImage—it worked flawlessly! Very impressive!

Now, I'm wondering if it's possible to use this tool to build AppImages for aarch64 to run on a Raspberry Pi.

So far, I have not been able to cross-compile a "Hello" AppImage, nor have I managed to build it natively on the Raspberry Pi as an AppImage.

Cross-compilation:

# on x86 nixos machine
$ nix bundle --bundler github:ralismark/nix-appimage 'nixpkgs#pkgsCross.aarch64-multiplatform.hello'

# On raspberry pi
$ ./hello-aarch64-unknown-linux-gnu-2.12.1-x86_64.AppImage
./hello-aarch64-unknown-linux-gnu-2.12.1-x86_64.AppImage: cannot exec /nix/store/4i7fkxnppy0d2zlp4c36yvc1a1jmsa4a-hello-aarch64-unknown-linux-gnu-2.12.1/bin/hello: Exec format error

Native build on raspberry pi

# On raspberry pi
$ nix bundle --bundler github:ralismark/nix-appimage 'nixpkgs#hello'

Compiling 'Hello' on a Raspberry Pi or cross-compiling it on an x86 machine without bundling it as an AppImage works perfectly fine.

Would you expect this to work in principle, or could you perhaps tell me what I might be doing wrong?

[ralismark]

I think this was an issue with the version of nixpkgs this project was pinned to. I've bumped it as part of a bigger refactor, so it should work now. Let me know if it's still broken!

Regarding cross-compiling bundling, it's a limitation of nix bundle (and flakes in general) that they don't support specifying how to cross-compile.

I can confirm it works on aarch64 (host is also aarch64). We have been using it over at https://github.com/Azathothas/Toolpacks [+] mpv: https://github.com/Azathothas/Toolpacks/blob/main/.github/scripts/aarch64_Linux/bins/mpv.sh [+] ladybird: https://github.com/Azathothas/Toolpacks/blob/main/.github/scripts/aarch64_Linux/bins/ladybird.sh and many more.

Thanks for confirming!
