Failing to build a Go 1.22 application on master

Help
1

I’m trying to package a Go application with Nix. I’m not a Go developer, so I might be missing something obvious. The expression that I’m starting from is minimal and follows examples seen elsewhere. This is on nixpkgs master because Go 1.22 is required.

Running nix build on this expression:

{ buildGoModule
, fetchFromGitHub
, lib
}:

buildGoModule rec {
  pname = "birdnet-go";
  version = "v0.5.2";

  src = fetchFromGitHub {
    owner = "tphakala";
    repo = pname;
    rev = "eafdfb492427eec3eecb4eb84d8530807ca89100";
    sha256 = lib.fakeHash;
  };

  vendorHash = lib.fakeHash;

  meta = with lib; {
    description = "AI solution for continuous avian monitoring and identification";
    homepage = "https://github.com/tphakala/birdnet-go";
    license = "Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International";
    maintainers = with maintainers; [ vandenoever ];
    mainProgram = "birdnet";
  };
}

gives me

What could be causing chmod to fail with Invalid argument?

I don’t know what is causing these errors, but the following works for me (maybe your master is too old):

{
  inputs = { nixpkgs.url = "github:NixOS/nixpkgs/master"; };
  outputs = { self, nixpkgs }:
    let
      system = "x86_64-linux";
      pkgs = nixpkgs.legacyPackages.${system};
    in {
      packages.${system}.default = pkgs.buildGoModule rec {
        pname = "birdnet-go";
        version = "v0.5.2";

        src = pkgs.fetchFromGitHub {
          owner = "tphakala";
          repo = pname;
          rev = "eafdfb492427eec3eecb4eb84d8530807ca89100";
          sha256 = "sha256-QqmLisDLwENDt7Xv+dFo+RE1H2Nkal2QDb7RDtuhVBQ=";
        };

        vendorHash = "sha256-aqcFcHLTTFJYvWdhEs72y3amQlrLw4q9tuAGQgQqCsg=";

        buildInputs = with pkgs; [ tensorflow-lite ];
      };
    };
}

Save it as flake or extract the derivation.

Cheers

The flake.nix you paste is what I would expect to work. But with nixpkgs master (d2d8db8cb7ff0d29be09cdb12a064c8bf73862a9) and nix 2.18.1, it gives:

@nix { "action": "setPhase", "phase": "unpackPhase" }

Building on NixOS 23.11 works fine after the requirement for a Go 1.22 is patched out:

{ buildGoModule, fetchFromGitHub, lib, tensorflow-lite }:

buildGoModule rec {
  pname = "birdnet-go";
  version = "v0.5.2";

  src = fetchFromGitHub {
    owner = "tphakala";
    repo = pname;
    rev = "eafdfb492427eec3eecb4eb84d8530807ca89100";
    sha256 = "sha256-QqmLisDLwENDt7Xv+dFo+RE1H2Nkal2QDb7RDtuhVBQ=";
  };

  vendorHash = "sha256-aqcFcHLTTFJYvWdhEs72y3amQlrLw4q9tuAGQgQqCsg=";

  patchPhase = ''
    sed -i 's/^go 1.22.2$/go 1.21.8/g' go.mod
  '';

  buildInputs = [ tensorflow-lite ];
}
