Problems setting up suyu emulator

Help
1

I’ve used this flake setup to add suyu to my home Manager configuration, but I keep getting an error I don’t understand:

flake.nix:

{
  description = "My NixOS Flake";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.11";
    chaotic.url = "github:chaotic-cx/nyx/nyxpkgs-unstable";
    home-manager = {
      url = "github:nix-community/home-manager/release-24.11";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    nixos-hardware.url = "github:NixOS/nixos-hardware/master";
    nix-gaming.url = "github:fufexan/nix-gaming";
    suyu = {
      url = "git+https://git.suyu.dev/suyu/nix-flake";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, chaotic, home-manager, nixos-hardware, nix-gaming, suyu, ... }@inputs: {
    nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      specialArgs = { inherit inputs; };
      modules = [
        ./configuration.nix
        nixos-hardware.nixosModules.asus-zephyrus-ga402x-amdgpu
        chaotic.nixosModules.default
        nix-gaming.nixosModules.platformOptimizations
      ];
    };

    homeConfigurations.user = home-manager.lib.homeManagerConfiguration {
      pkgs = nixpkgs.legacyPackages.x86_64-linux;
      extraSpecialArgs = { inherit inputs; };
      modules = [
        ./home.nix
        chaotic.homeManagerModules.default
        suyu.packages.x86_64-linux.suyu
      ];
    };
  };
}

when I update home manager, I get this error:

 home-manager switch --flake .

as far as changes I made to my home manager, it was just adding pkgs.suyu to it:

{ config, pkgs, ... }:

{

  home.username = "user";
  home.homeDirectory = "/home/user";
  home.stateVersion = "25.05"; # Please read the comment before changing.
  nixpkgs.config.allowUnfree = true;
  nixpkgs.config.allowBroken = true;

  nixpkgs.config.permittedInsecurePackages = [
     #"electron-27.3.11" # I think teams or goofcord idk
     "olm-3.2.16" #for neochat
  ];

  nix.package = pkgs.nix;

  home.packages = [
    pkgs.suyu
  ];

can anyone tell me what to do?

errors because a package is not a module, so remove this.

That won’t work without an overlay, you need to use inputs.suyu.packages.x86_64-linux.suyu

Thank, this helped, I updated my flake.nix to this:

{
  description = "My NixOS Flake";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.11";
    chaotic.url = "github:chaotic-cx/nyx/nyxpkgs-unstable";
    home-manager = {
      url = "github:nix-community/home-manager/release-24.11";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    nixos-hardware.url = "github:NixOS/nixos-hardware/master";
    nix-gaming.url = "github:fufexan/nix-gaming";
    suyu = {
      url = "git+https://git.suyu.dev/suyu/nix-flake";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, chaotic, home-manager, nixos-hardware, nix-gaming, suyu, ... }@inputs:
  let
    system = "x86_64-linux";

    # Define overlays
    overlays = [
      (final: prev: {
        suyu = suyu.packages.${system}.suyu;
      })
    ];

    pkgs = import nixpkgs {
      inherit system overlays;
      config.allowUnfree = true;
    };
  in {
    nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
      inherit system;
      specialArgs = { inherit inputs; };
      modules = [
        ./configuration.nix
        nixos-hardware.nixosModules.asus-zephyrus-ga402x-amdgpu
        chaotic.nixosModules.default
        nix-gaming.nixosModules.platformOptimizations
      ];
    };

    homeConfigurations.user = home-manager.lib.homeManagerConfiguration {
      inherit pkgs;
      extraSpecialArgs = { inherit inputs; };
      modules = [
        ./home.nix
        chaotic.homeManagerModules.default
      ];
    };
  };
}

there’s probably better/shorter ways to do it but I don’t know.
this got me to start building suyu when doing home-manager switch --flake . but it has some dependency erros now that I’m not sure about:

 home-manager switch --flake . --show-trace

Yeah suyu not building is a whole other thing, it hasn’t been updated in 7 months so that’s not surprising. You’ll have to go full-on c++ developer mode to fix that, probably a missing header or maybe the vulkan API’s changed since then, no idea offhand.
