NixOS stable - Emacs ImageMagick support

Help
3

Hy,
thanks for the quick reply!

The package is called from all-packages.nix with
imagemagick => null so you need to use something like this,

nixpkgs.emacs.override { inherit (nixpkgs) imagemagick; }

Hum, maybe I do not understand (my nix knowledge is rather limited),
using directly this expression in my config result in an error so I
tried to “override” in nixpkgs.config like:

 packageOverrides = pkgs: {
   emacs = pkgs.emacs.override {
     imagemagick = true;
  };
 };

However nixos-rebuild fail with

building '/nix/store/rxzlpnpmicmbwxgxxfp5gk5m0wn1a928-emacs-26.1.drv'...
build input 1 does not exist

Where am I wrong?

Unfortunately this does mean that you will be building emacs yourself;
fortunately it’s not the slowest build out there.
That’s ok, expected and not much a problem since Emacs on stable
does not change too frequently :slight_smile:
