Build issues with Nix

[rrrnld]

Hi!

I wanted to build this package using Nix, and package it for NixOS. I started by writing a flake that would allow me to build it in a dev shell. This is what I've come up with:

{
  inputs.nixpkgs.url = github:NixOS/nixpkgs;

  outputs = { self, nixpkgs, ... }: let
    system = "x86_64-linux";
    pkgs = import nixpkgs { inherit system; };
    lib = pkgs.lib;
  in {
    devShells.${system}.default = pkgs.mkShell {
      buildInputs = [
        pkgs.cmake
        pkgs.gnumake
        pkgs.pkg-config
      ];

      nativeBuildInputs = [
        pkgs.alsa-lib
        pkgs.curl.dev
        pkgs.freetype
        pkgs.libGLU
        pkgs.webkitgtk
        pkgs.xorg.libX11
        pkgs.xorg.libXrandr
        pkgs.xorg.libXinerama
        pkgs.xorg.libXext
        pkgs.xorg.libXcursor
        pkgs.xorg.libXi.dev

        # outputs warnings when running cmake ..
        pkgs.pcre.dev
        pkgs.pcre2.dev
        pkgs.util-linux.dev
        pkgs.libselinux.dev
        pkgs.libsepol.dev
        pkgs.libthai.dev
        pkgs.libdatrie.dev
        pkgs.xorg.libXdmcp.dev
        pkgs.libxkbcommon.dev
        pkgs.libepoxy.dev
        pkgs.xorg.libXtst
        pkgs.libsysprof-capture
        pkgs.sqlite.dev
        pkgs.libpsl
      ];
    };
  };
}

However, the build is currently failing ( with lines like this:

git clone https://github.com/plugdata-team/plugdata && cd plugdata && git checkout v0.8.3
mkdir build && cd build
cmake ..
cmake --build . -j 4

Any idea what's causing the build to fail? I'm quite excited to try this out, thank you!

Why are you not pulling the submodules?

Add a git submodule update --init --recursive after your checkout.

But I'm pretty sure there already is a Nix package out there? 🤔

Oh, indeed there is? https://github.com/NixOS/nixpkgs/blob/352e7d330a26cb113d0493046cfeb1aea268b127/pkgs/applications/audio/plugdata/default.nix#L20 I don't know why I didn't see that 😬 Thanks!

It's a bit outdated, but maybe you can help to update it :)
