[Nix-dev] ioquake3 on nixos

[Nikolay Amiantov]

I play ioquake3 successfully. It needs the following to work:

1. Extract pak0.pk3 file from the original Quake 3 Arena.
2. Use Nix script like this:

{ nixpkgs ? import <nixpkgs> { } }:

let
  paks = nixpkgs.stdenv.mkDerivation {
    name = "quake3-arena";
    pak0 = ./baseq3/pak0.pk3; # Replace this with path to your file
    buildCommand = ''
      install -D -m644 $pak0 $out/baseq3/pak0.pk3;
    '';
  };
in nixpkgs.quake3wrapper {
  paks = [ paks nixpkgs.quake3pointrelease ];
}

3. Run `nix-build` on it: `nix-build script.nix`
4. `result/bin/quake3` would run the game.

This probably needs to be added to our manual and/or improved somehow.

For the development, however, you can just run `nix-shell` as advised by
Emery -- it would get you all the game dependencies, so you can use
conventional tools (make/cmake/gcc/whatever ioquake3 wants) inside the
shell.
