Building a GTK application fails without an error message

[savannidgerinel]

I have a GTK application that I am trying to build with crate2nix, and I am consistently getting this sort of error message on three different crates that the app depends upon.

The repository in question is https://git.luminescent-dreams.com/savanni/tools . I am working on the feature/build-tools branch.

The following error occurs for gobject-sys, graphene-sys, and cairo-sys. Which one appears in any given build attempt is random.

error: builder for '/nix/store/fdli8kfywpnh5clb73y5axcgmkksxiw1-rust_cairo-sys-rs-0.17.0.drv' failed with exit code 1;

I get the same error with graphene-sys and gobject-sys. The order of the build execution is non-deterministic, so I may hit any one of these on any given build.

I'm building from a flake. Eliding the entire devShell, I'm down to just this:

{
  description = "Luminescent Dreams Tools";

  inputs = {
    nixpkgs.url = "nixpkgs/nixos-22.11";
    unstable.url = "nixpkgs/nixos-unstable";
    pkgs-cargo2nix.url = "github:cargo2nix/cargo2nix";
  };

  outputs = { self, nixpkgs, unstable, pkgs-cargo2nix, ... }:
    let 
      version = builtins.string 0 8 self.lastModifiedDate;
      supportedSystems = [ "x86_64-linux" ];
    in
    {
        packages."x86_64-linux" =
          let
            pkgs = import nixpkgs { system = "x86_64-linux"; };
            customBuildInfo = pkgs: pkgs.buildRustCrate.override {
              defaultCrateOverrides = pkgs.defaultCrateOverrides // {
                gobject-sys = attrs: {
                  nativeBuildInputs = [
                    pkgs.pkg-config

                    pkgs.gtk4
                    pkgs.glib
                    pkgs.clang
                  ];
                };
                graphene-sys = attrs: {
                  nativeBuildInputs = [
                    pkgs.pkg-config
                    pkgs.wrapGAppsHook4
                    pkgs.gtk4
                    pkgs.glib
                    pkgs.clang
                  ];
                };
                cairo-sys = attrs: {
                  nativeBuildInputs = [
                    pkgs.pkg-config
                    pkgs.wrapGAppsHook4
                    pkgs.gtk4
                    pkgs.glib
                    pkgs.clang
                  ];
                };
              };
            };
          in {
            kifu-gtk = (import ./kifu/kifu-gtk/Cargo.nix {
              inherit pkgs;
              buildRustCrateForPkgs = customBuildInfo;
            }).rootCrate.build;
          };
    };
}

I run the build from the root of my repository with this:

nix build .#kifu-gtk

Having now banged my head against this for many hours, I have found a solution. Maybe not the intended one.

Even with the documentation in the readme I had trouble setting up the crate overrides to add the relevant native builds. I would like to submit some documentation illustrating the problem above and the solution.

Which, btw, looks like this:

        packages."x86_64-linux" =
          let
            pkgs = import nixpkgs { system = "x86_64-linux"; };
            standardOverride = attrs: {
                nativeBuildInputs = [
                  pkgs.pkg-config
                  pkgs.gtk4
                  pkgs.glib
                ];
                verbose = true;
            };
            customBuildInfo = pkgs: pkgs.buildRustCrate.override {
              defaultCrateOverrides = pkgs.defaultCrateOverrides // {
                cairo-sys-rs = standardOverride;
                graphene-sys = standardOverride;
                gobject-sys = standardOverride;
                pango-sys = standardOverride;
                gio-sys = standardOverride;
                gdk-pixbuf-sys = standardOverride;
                gdk4-sys = standardOverride;
                gsk4-sys = standardOverride;
                gtk4-sys = standardOverride;
              };
            };
          in {
            # gobject-sys = pkgs.buildRustCrate cargo.internal.crates.gobject-sys;
            kifu-gtk = (import ./kifu/kifu-gtk/Cargo.nix {
              inherit pkgs;
              buildRustCrateForPkgs = customBuildInfo;
            }).rootCrate.build;
          };

I think that, unless there is something wrong in what I wrote, this is the final solution.

Shouldn't this be reopened to at least provide some meaningful error message or link to this issue?
