Raylib static library files not found by ld

Help

Hi everyone, I have the following issue:

I made a program using Odinlang, which can be found at GitHub - Vonixxx/Search.

The build.sh file consists of the following:

odin build Source -file -out:search -o:aggressive -microarch:native

In order to build it on NixOS (I use the unstable branch, recently updated), the following flake.nix file is provided, to be used with nix develop:

   1   │ {
   2   │  inputs = {
   3   │    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
   4   │  };
   5   │ 
   6   │  outputs = {
   7   │    nixpkgs
   8   │  , ...
   9   │  }:
  10   │ 
  11   │  let
  12   │   pkgs = import nixpkgs {
  13   │      system = "x86_64-linux";
  14   │   };
  15   │  in with pkgs; {
  16   │    devShells.x86_64-linux.default = mkShell {
  17   │      LD_LIBRARY_PATH = "$LD_LIBRARY_PATH:${
  18   │         lib.makeLibraryPath [
  19   │          libGL
  20   │          xorg.libX11
  21   │         ]
  22   │      }";
  23   │ 
  24   │      buildInputs = [
  25   │        libGL
  26   │        odin
  27   │        xorg.libX11
  28   │      ];
  29   │ 
  30   │      shellHook = ''
  31   │         alias run='odin run .'
  32   │         alias build='odin build .'
  33   │      '';
  34   │    };
  35   │  };
  36   │ }

Running nix develop and then ./build.sh successfully builds the program and works as intended when executed.

But now I am trying to test it by packaging it for nixpkgs, so I can use it on my system. I have cloned the nixpkgs repository and done the usual, i.e. placing the callPackage at the top-level and placing the corresponding package.nix in the appropriate by-name directory, which is the following:

   1   │ { lib
   2   │ , odin
   3   │ , xorg
   4   │ , libGL
   5   │ , stdenv
   6   │ , fetchFromGitHub
   7   │ , ...
   8   │ }:
   9   │ 
  10   │ stdenv.mkDerivation {
  11   │   version = "1.0";
  12   │   pname   = "search";
  13   │ 
  14   │   src = fetchFromGitHub {
  15   │     repo  = "Search";
  16   │     owner = "Vonixxx";
  17   │     rev   = "96658de77432ea2106ea49224efee365e4601a99";
  18   │     hash  = "sha256-I3vE9eaRNuz6ADcz65TWt7nY5B/NKFD446SqNX1FGq8=";
  19   │   };
  20   │ 
  21   │   LD_LIBRARY_PATH = "$LD_LIBRARY_PATH:${
  22   │      lib.makeLibraryPath [
  23   │       libGL
  24   │       xorg.libX11
  25   │      ]
  26   │   }";
  27   │ 
  28   │   buildInputs = [
  29   │     odin
  30   │     libGL
  31   │     xorg.libX11
  32   │   ];
  33   │ 
  34   │   postPatch = ''
  35   │      patchShebangs build.sh
  36   │   '';
  37   │ 
  38   │   buildPhase = ''
  39   │      runHook preBuild
  40   │ 
  41   │      ./build.sh
  42   │ 
  43   │      runHook postBuild
  44   │   '';
  45   │ 
  46   │   installPhase = ''
  47   │      runHook preInstall
  48   │ 
  49   │      install -Dm755 search $out/bin/search
  50   │ 
  51   │      runHook postInstall
  52   │   '';
  53   │ 
  54   │   meta = {
  55   │     inherit (odin.meta) platforms;
  56   │ 
  57   │     mainProgram = "search";
  58   │     license     = lib.licenses.mit;
  59   │     description = "Simple Search Program";
  60   │     homepage    = "https://github.com/Vonixxx/Search";
  61   │ 
  62   │     maintainers = with lib.maintainers; [
  63   │       vonixxx
  64   │     ];
  65   │   };
  66   │ }

Attempting to build it with nix-build -A search, I get the following error:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: builder for '/nix/store/msbwyhz3wmys734qvndswbxipk77fxsw-search-1.0.drv' failed with exit code 1;

When I look at the respective directories, I can see that the files are there:

┌󰜗 nixpkgs  master [⇡] 2s 
└❮ ls /nix/store/dq6mlgndxymscnhxfyb38k5pn5i1cixf-odin-dev-2024-07/share/vendor/raylib/linux

└──  libraylib.so.500@ ⇒ libraylib.so.5.0.0

So what gives? I’d appreciate it if anyone could help.

Definitely don’t set LD_LIBRARY_PATH like that when packaging. It won’t affect the final binary unless you wrapped, and it’s bad practice anyway.

Use patchelf (or even easier, autoPatchelfHook) to point the binary at the libs you want (see nixpkgs manual for details).

Also, don’t use ... in package expressions :slight_smile:

There’s some other best-practice stuff but those will come up during review if you end up submitting to nixpkgs.

I removed the LD_LIBRARY_PATH, as well as the …

I added the following two blocks:

  21   │   nativeBuildInputs = [
  22   │     autoPatchelfHook
  23   │   ];

  31   │   preBuild = ''
  32   │      addAutoPatchelfSearchPath ${odin}/share/vendor/raylib/linux
  33   │   '';

However, the issue still persists.

I’ve looked around some more, yet no luck.
Am I using autoPatchelfHook wrongly?

I would highly appreciate some insight!
