as of today I started to get errors cross-compiling gnutls on armv7:

./errcodes: line 117: /build/gnutls-3.8.12/doc/.libs/lt-errcodes: cannot execute binary file: Exec format error

hey hi howdy, I'm trying to cross compile to wasm32-wasi using rust with the fenix and crane libraries but getting errors in the build and devshell. any tips?

Here's my expression:

let
  inherit (pkgs) lib stdenv;

  sources = import ./npins;
  system = builtins.currentSystem;

  pkgs =
    let
      pkgs = import sources.nixpkgs {
        localSystem = { inherit system; };
      };
    in
    pkgs.pkgsCross.wasi32;

  fenix = import sources.fenix {
    inherit system pkgs;
  };
  toolchain = with fenix; combine [
    (stable.withComponents [
      "rust-analyzer"
      "rust-src"
      "cargo"
      "rustc"
      "rustfmt"
      "clippy"
    ])
    targets.wasm32-unknown-unknown.latest.rust-std
  ];
  crane =
    let
      crane = import sources.crane {
        inherit pkgs;
      };
    in
    crane.overrideToolchain toolchain;

  lathe =
    { lib
    , stdenv
    , libiconv
    , autoPatchelfHook
    }:
    crane.buildPackage {
      src = crane.cleanCargoSource ./.;
      strictDeps = true;

      nativeBuildInputs = [
        # Additional compile time deps
      ] ++ lib.optionals stdenv.isDarwin [
        # macOS only compile time deps
        libiconv
      ] ++ lib.optionals stdenv.isLinux [
        # linux only compile time deps
        autoPatchelfHook
      ];

      buildInputs = with pkgs; [
        # runtime dependencies
      ];
    };
in
{
  default = pkgs.callPackage lathe { };

  devshell = crane.devShell {
    packages = with pkgs; [
      npins
    ];
  };
}
