Issues with openGL in minecraft development environments

Help
1

hi! I’m fairly new to nixos, and had a wonderful, seamless experience. for a month. upon updating to nixos 23.11 (I now use unstable, which also does not work), running Minecraft from an IDE to develop mods no longer works, failing with an OpenGL exception:

[LWJGL] Platform/architecture mismatch detected for module: org.lwjgl.opengl
        JVM platform:           Linux amd64 21

        Platform available on classpath:
                linux/x64

Minecraft loads fine from Prism Launcher, however this error makes it impossible for me to work on my mods.

Can you narrow down what process is throwing the exception / what kinds of system calls it’s doing just before?

That is definitely useful. Someone with more java exp may be able to say more.

Next thing I would want to know is where the java lib is looking for libGL.so. strace is a good way of doing this. Once you can see that, it should give you a fairly good idea why java can’t find the openGL lib

libGL.so is available through libglvnd.

running Minecraft from an IDE to develop mods no longer works, failing with an OpenGL exception:

To make this library available, you can use LD_LIBRARY_PATH which can extend the default locations for glibc to look for dynamic libraries. To do this, you want to run something like export LD_LIBRARYPATH="${LD_LIBRARY_PATH}${LD_LIBRARY_PATH:+:}/nix/store/yw48bqgswppkcrx303ybgbn6r2nqbda1-libglvnd-1.7.0/lib

Ideally, this would take the form of using nix develop:

# devShell.nix or shell.nix
{ mkShell
, libglvnd
...
}:

mkShell {
...
  shellHook = ''
    export LD_LIBRARY_PATH="''${LD_LIBRARY_PATH}''${LD_LIBRARY_PATH:+:}${libglvnd}/lib"
  '';
}

here’s the full strace: Hastebin
I’m also working on applying @jonringer 's solution

7

if you’re running the steps within the IDE, then a lot of those will create new shells which don’t inherit shell variables. So LD_LIBRARY_PATH isn’t being communicated. Not sure of your IDE setup, but they generally allow you to extend the shell variables.

8

do you know of any way I could solve this issue for my full system, instead of adding files to each env I want to work with?

to clarify: thank you so much for the environment variable solution! I just ideally want something that’ll persist across my whole computer

Maybe nix-ld would help? Nix-ld: A clean solution for issues with pre-compiled executables on NixOS | ~/git/blog

https://search.nixos.org/options?channel=23.11&from=0&size=50&sort=relevance&type=packages&query=nix-ld

i had this same issue, i managed to get it working system-wide. im new to nixos so this probably isnt the right way but it seems to work just fine with intellij idea.

like jonringer said you can edit the LD_LIBRARY_PATH in your ide, which i did until i found one that worked, for me it was /nix/store/jz3vvf4nsyirb25rh9dbhksm4gq6wybb-libglvnd-1.7.0/lib/:/nix/store/pn9glkalcj7i5p549dpsl1c46pkb13xr-pulseaudio-17.0/lib/

which is the libglvnd for libGL.so.1 and also i had to add the pulseaudio one for openAL because it was missing that too somehow.

and then to make that global i just added it to my configuration.nix by adding this:

environment.sessionVariables = rec {
    LD_LIBRARY_PATH = "/nix/store/jz3vvf4nsyirb25rh9dbhksm4gq6wybb-libglvnd-1.7.0/lib/:/nix/store/pn9glkalcj7i5p549dpsl1c46pkb13xr-pulseaudio-17.0/lib/";
};

and then logging out and back in again.

Congrats on your ingenuity and welcome to the forum! The more future-proof way to do this would be:

environment.sessionVariables = {
  LD_LIBRARY_PATH = lib.makeLibraryPath [
    pkgs.libglvnd
    pkgs.pulseaudio
  ];
};
