Error overriding picom

Help
1

I’m following the wiki and attempting to override the default Picom package with the latest next branch.

I’ve added the following to my Nix configuration:

  environment.systemPackages = with pkgs; [
    # ...
    (picom.overrideAttrs (oldAttrs: rec {
      src = fetchFromGitHub {
        owner = "yshui";
        repo = "picom";
        rev = "f4fcedc470d39ce21caae4d1d0f73dd7f0b2600e";
        hash = "sha256-59I6uozu4g9hll5U/r0nf4q92+zwRlbOD/z4R8TpSdo=";
      };
    }))
  ];

However, when I try to rebuild the system, I encounter this error:

warning: Git tree '/home/heiytor/nixos' is dirty

Adding asciidoctor to systemPackages did not resolve the issue.

Adding a package to systemPackages does not make it available at build time.
What you want to do is also override nativeBuildInputs and add your package there.

(picom.overrideAttrs (oldAttrs: rec {
      src = fetchFromGitHub {
        owner = "yshui";
        repo = "picom";
        rev = "f4fcedc470d39ce21caae4d1d0f73dd7f0b2600e";
        hash = "sha256-59I6uozu4g9hll5U/r0nf4q92+zwRlbOD/z4R8TpSdo=";
      };
     nativeBuildInputs = [
         asciidoctor
     ] ++ oldAttrs.nativeBuildInputs;
    }))

Should be along the lines of what you want.
