Building without patches, but maybe this (untested) code removing only the bytecomp patch is better:

  patches = lib.filter (patch: patch.name or (toString patch) != "bytecomp-revert.patch") old.patches;

Or perhaps I need to fix the bytecomp patch and it's still needed. It says its for #318 so I might not need it on my vanilla x86_64 linux but could be needed by others.

Oh forgot to update, that didn't work so I just rolled my flake back to an earlier version for now.

The following works for me:

nope

``` nix programs.emacs = { enable = true; package = (pkgs.emacs-git.override { … }).overrideAttrs(old: { patches = builtins.filter (patch: builtins.baseNameOf patch != "bytecomp-revert.patch") old.patches; }); … } ```

Sadly I get this error that might be related to that patch somehow:

Oh, sorry about that; maybe I should've let Emacs finish building before posting

[leungbk]

I'm not sure if the bytecomp-revert patch is needed at all anymore since Mattias E. made some recent changes upstream...but anyway, I pushed some commits here to make sure the patch applies.

BTW, at the time of writing, the overlay's version of Emacs 30 works on nixos-unstable but not release-23.11 since we merged https://github.com/NixOS/nixpkgs/pull/277331 fairly late. If this bothers anyone, let me know and I'll revert https://github.com/nix-community/emacs-overlay/pull/378 temporarily.
