Help building Rust Bevy example games

hi @bernborgess – you are close, but missing a few dependencies and inputs that could get a dev shell working with bevy. Fortunately, the bevy community does have a recommended/minimal flake.nix to get you started – bevy/docs/linux_dependencies.md at 5f8270f2e049f90139a503d1e930070d926f9427 · bevyengine/bevy · GitHub

  description = "bevy flake";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    rust-overlay.url = "github:oxalica/rust-overlay";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs =
    {
      nixpkgs,
      rust-overlay,
      flake-utils,
      ...
    }:
    flake-utils.lib.eachDefaultSystem (
      system:
      let
        overlays = [ (import rust-overlay) ];
        pkgs = import nixpkgs {
          inherit system overlays;
        };
      in
      {
        devShells.default =
          with pkgs;
          mkShell {
            buildInputs =
              [
                # Rust dependencies
                (rust-bin.stable.latest.default.override { extensions = [ "rust-src" ]; })
                pkg-config
              ]
              ++ lib.optionals (lib.strings.hasInfix "linux" system) [
                # for Linux
                # Audio (Linux only)
                alsa-lib
                # Cross Platform 3D Graphics API
                vulkan-loader
                # For debugging around vulkan
                vulkan-tools
                # Other dependencies
                libudev-zero
                xorg.libX11
                xorg.libXcursor
                xorg.libXi
                xorg.libXrandr
                libxkbcommon
              ];
            RUST_SRC_PATH = "${pkgs.rust.packages.stable.rustPlatform.rustLibSrc}";
            LD_LIBRARY_PATH = lib.makeLibraryPath [
              vulkan-loader
              xorg.libX11
              xorg.libXi
              xorg.libXcursor
              libxkbcommon
            ];
          };
      }
    );
}

I did the following:

git clone git@github.com:bevyengine/bevy.git
cd bevy
# create flake.nix with above contents
vim flake.nix 
git add flake.nix
nix develop
cargo run --example bloom_2d
