After a recent update(nix flake update), my Emacs configuration is failing to load. I'm getting errors indicating missing dependencies for several packages:

Loading /nix/store/7ad3rrwnr9m9z6gbr2c9nakq7yqks4gc-emacs-30.1/share/emacs/site-lisp/site-start (native compiled elisp)...done

In the latest nixpkgs-unstable, use-package in Emacs-overlay ignore all dependcies?

My configuration:

              emacsPkg = pkgs.emacsWithPackagesFromUsePackage {
                config = ./emacs/init.el;
                defaultInitFile = true;
                package = pkgs.emacs-unstable.override {
                  withNativeCompilation = false;
                };
                alwaysEnsure = false;
                alwaysTangle = true;
                extraEmacsPackages =
                  epkgs: with epkgs; [
                    treesit-grammars.with-all-grammars
                  ];
              };

;; Magit additional configurations
(use-package magit
  :ensure t
  :bind (:map magit-status-mode-map
              ("C-M-<up>" . magit-section-up))
  :config
  (when *is-a-mac*
    (add-hook 'magit-mode-hook (lambda () (local-unset-key [(meta h)])))))

Those errors was gone after I pin nixpkgs to a398296

Could you provide a minimal reproducing example (in a new issue, ideally)? I do not see your ./emacs/init.el. Is withNativeCompilation = false; necessary?

withNativeCompilation = false; is not necessary.

OK, I understand. I'll add an example later.

1. Install eamcs-overlay: https://github.com/nix-community/emacs-overlay
2. Configure Emacs in flake.nix

environment.systemPackages = [
  (
    pkgs.emacsWithPackagesFromUsePackage {
      config = ./emacs/init.el;
      defaultInitFile = true;
      alwaysEnsure = false;
      alwaysTangle = true;
      extraEmacsPackages =
	epkgs: with epkgs; [
          treesit-grammars.with-all-grammars
	];
    };
  )
];

3. ./emacs/init.el

(use-package magit
  :ensure t
  :config
  (setq-default magit-diff-refine-hunk 'all)

Edit: The Emacs package itself doesn't seem to be the issue. This error occurs with pkgs.emacs, pkgs.emacs-unstable, and pkgs.emacs-git.

emacs-overlay and nixpkgs commit hash?

nixpkgs: 2d9e445
Emacs-overlay: 6a25d3f956603e1f18499f33951ad6f2a9fa2f6e

@ngn999 It is caused by a stdenv bug and here is my fix PR. Since that fix PR needs to go through a staging cycle which takes a few weeks, I will revert d64a233 for now.

Thanks for the report.

Hi. Any idea how a dependency can be added to an emacs package after this change? I used to have:

package.overrideAttrs (old: {
  packageRequires = old.packageRequires ++ [ d ];
  propagatedBuildInputs = old.propagatedBuildInputs ++ [ d ];
  propagatedUserEnvPkgs = old.propagatedUserEnvPkgs ++ [ d ];
})

But now it doesn't work. If I got it right propagatedUserEnvPkgs isn't properly updated as I can't see propagated-user-env-packages in the package output at all.
