I’m developing on aarch64-darwin using Nix flakes for my Haskell project.
It just occurred to me that there seems to be no way for an aarch64-darwin user to use the binaries produced by default. I tried anyway and got the predictable path /nix/.../glib does not exist error.
My first thought was “binary size doesn’t matter so much, I’ll use nix bundle” but that’s not supported on aarch64-darwin.
My next thought was the obvious “I know… I can use pkgsCross.aarch64-multiplatform-musl.pkgsStatic.haskell.packages.ghc92”.
The only problem is that I got some assembler error on aarch64, and even on x86_64-linux I got errors with:
$ nix build nixpkgs#pkgsCross.aarch64-multiplatform-musl.pkgsStatic.haskell.compiler.ghc96
error:

Maybe one of the other cross architectures can work for my use case of “someone using aarch6-darwin that doesn’t have nix installed”?
Maybe just pkgsStatic is needed?
Of course I get the same error even for nix build nixpkgs#pkgsStatic.haskell.compiler.ghc96.
Any help or guidances is appreciated.
