(nix) Hyprland + nixpkgs 25.05

[patrickaldis]

Just wondering the procedure for getting a release version of hyprland on NixOS 25.05 from the flake

My current setup has nixpkgs, home manager pinned to 25.05, with the NixOS module from the flake.

If I wanted to use Hyprland 50.1, then I currently get the following error on rebuild:

   (stack trace truncated; use '--show-trace' to show the full, detailed trace)

   error: attribute 'gcc15Stdenv' missing
   at /nix/store/9nxywik565wii0harakdpw53aakriqlr-source/nix/overlays.nix:39:18:
       38|       hyprland = final.callPackage ./default.nix {
       39|         stdenv = final.gcc15Stdenv;
         |                  ^
       40|         commit = self.rev or "";
   Did you mean one of gcc10Stdenv, gcc11Stdenv, gcc12Stdenv, gcc13Stdenv or gcc14Stdenv?

I take it this is because gcc15 wasn't in nixpkgs 25.05? Is the correct procedure, if I didn't want to bump my version, to add my own overlay for gcc15 from unstable? Am I going to run into a lot of similar dependency issues?

Thanks for any help!

Are you overriding hyprland's nixpkgs input?

[patrickaldis]

Hi, no I'm not

[fufexan]

Then are you consuming the flake through an overlay? Because this should not happen unless the flake was overridden.
