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? _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
