Hey, how can I allow unfree packages in my unstable flake overlay?
NVM i found a way

{ config, pkgs, ... }:
              let
                overlay-unstable = final: prev: {
                  unstable = import nixpkgs-unstable {
                    system = "x86_64-linux";
                    config.allowUnfree = true;
                  };
                };
              in
              {
                nixpkgs.overlays = [ overlay-unstable ];
              }

I created a post on discourse but I wanted to ask here as well:

I'm trying to set up a dev environment using flakes so that I can develop cores for the MiSTer FPGA project. The project requires version 17.0.2.602 of Quartus Prime, the Intel (né Altera) FPGA IDE.

Nixpkgs-unstable currently references 23.1std.0.991. Is it possible (and reasonable) to somehow adapt quartus.nix so that I can create a flake that uses v17.0.2.602?

Hello. I am trying to use https://nixos.wiki/wiki/Flutter, but running flutter run inside nix-develop I get this error:

Launching lib/main.dart on Linux in debug mode...
Building Linux application...                                   
CMake Error in CMakeLists.txt:
  Imported target "PkgConfig::GTK" includes non-existent path

    "/nix/store/l0zdl1j9gc4w9j5b5k725m8fhlvmx7cb-graphite2-1.3.14/include"

  in its INTERFACE_INCLUDE_DIRECTORIES.  Possible reasons include:

  * The path was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and references files it does not
  provide.



CMake Generate step failed.  Build files cannot be regenerated correctly.
Error: Unable to generate build files

Anybody know what I do wrong?

It seem "graphite2" package misses /include folder..
