plots: GLSL 3.30 is not supported

MichaelBrunn3r commented 3 weeks ago

Describe the bug

plots crashes upon startup with the error (it's massive, here is the relevant bit):

Steps To Reproduce

Install plots from 24.05 or unstable channel
Execute: > plots

Expected behavior

Launch the plots App.

Additional context

The project repo of plots already has a workardound (https://github.com/alexhuntley/Plots/issues/151):

> GDK_DEBUG=gl-prefer-gl plots

idk what can I do with this issue. This is a dependency error with OpenGL.

I thought as a hotfix there might be a possibility to wrap the binary with an environment that has that environment variable set. I'm not an expert on derivations, don't know if that's possible. Otherwise, this should be fixed in the next release of plots as the developers are already aware of it

Nice, I got an overlay working that just wraps the program and sets GDK_DEBUG=gl-prefer-gl

{
  pkgs,
  ...
}: {
  config = {
    environment.systemPackages = with pkgs; [
      plots
    ];

    nixpkgs = {
      overlays = [
        (self: super: {
          plots = super.plots.overrideAttrs (old: {
            buildInputs = old.buildInputs ++ [pkgs.makeWrapper];
            postInstall =
              old.postInstall
              or ""
              + ''
                wrapProgram "$out/bin/plots" --set GDK_DEBUG gl-prefer-gl
              '';
          });
        })
      ];
    };
  };
}

Now running plots from the CLI or Gnome Shortcut works without issue 👍️

NixOS / nixpkgs
