 moon | * Hi! I'm a bit new to NixOS and to flakes. I'm using flakes to create a Java dev environment, and the program I'm developing wants to dynamically link libGL.so.1 and cannot find it. I'm trying to use nix-ld to solve this problem and set LD_LIBRARY_PATH. I might be doing something wrong in multiple places, and I'm wondering if I should share a snippet of my flake file. Please let me know if there is a better room to ask this question. Thanks! | 00:08:57 |
 Trent Baldwin | Are you trying to build a Java program for nix or just set up a dev environment? | 02:29:10 |

 n4ch723hr3r | you use devShells for that | 13:44:39 |
| moon | I think I misunderstood the purpose of nix develop and need to read through the nix-shell man page. I appreciate the devShells rec I didn't know about that project.

 atagen | devShells is not a project, it's an output of a nix flake
ie.
{
outputs =
{ self, nixpkgs }:
let
system = "x86_64-linux";
pkgs = nixpkgs.legacyPackages.${system};
in
{
devShells.${system}.default = pkgs.mkShell { packages = [ pkgs.hello ]; };
};
}

| atagen | if you are looking at devenv or something it's totally different and usually unnecessary | 01:47:10 |

if you are looking at devenv or something it's totally different and usually unnecessary oh i see! i need to read up on this. sounds like i was heading in the right direction with a flake, but wasn't using devShells to wrap my mkShell. will report back | 07:27:29 |

| SCOTT-HAMILTON | Hello, I have a environment that is built with buildEnv.
I've added this buildEnv to a devShell's packages and I can confirm that when I run nix develop the environment is accessible.
How can I create a bash default runnable (nix run) such that running it is equivalent to running nix develop and then running the bash script ?

| atagen | are you perhaps looking for shellHook in the mkShell ? | 04:16:03 |
| atagen | using nix run to enter a dev shell seems a little off but if you put the bash script into the shell packages and execute it in shellHook I think you can achieve what you want | 04:17:34 |

 woobilicious | open the flake in nix repl and look at the devShell attrset to see how it works. and I think for nix run to work you just set mainProgram in the meta section of a package, plenty of examples in nixpkgs. | 06:17:36 |
