Thanks,

yes at least the syntax is fine, but sadly does not change anything.

I cant even import qtengine manualy with the installed python (3.5)
interpreter.

not with

import qtwebengine  or
import webengine   or
import QtWebEngine 5.7 or
import QtWebEngine

and qutebrowser also tells me taht I should install qtwebengine when I
try to start it with "--backend webengine"

Try

  packageOverrides = pkgs: rec {
qutebrowser = pkgs.qutebrowser.overrideDerivation (oldAttrs: rec {
  nativeBuildInputs = oldAttrs.nativeBuildInputs ++ [
pkgs.qt5.qtwebengine
  ];
});
  };

[Nix-dev] how to add buildInput with derivation

[Stefan Huchler]

Because I have problems with qutebrowser I want to try out the new
qtwebengine backend.

I am not 100% shure that I edit the right variable but I want to add
qtwebengine to the buildInputs variable of that package:

   {
 packageOverrides = pkgs: rec {
   qutebrowser = pkgs.stdenv.lib.overrideDerivation pkgs.qutebrowser 
(oldAttrs : {
 buildPythonApplication.buildInputs = [
   qtbase qtwebkit-plugins qtwebengine
   gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly 
gst-libav
   glib_networking
 ];
   });
 };
   }

I get then the error:

error: undefined variable ‘qtbase’ at /home/.../.nixpkgs/config.nix:5:12

here is the package I want to manipulate:

https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/networking/browsers/qutebrowser/default.nix

Can somebody give me a hint what I did wrong? And if that that would
work to get the qtwebengine backend availible?
