Packaging for NixOS, error not comprehensive

[Aleksanaa]

I used to run valent on archlinux and it worked well. Then after I've packaged it for NixOS, it doesn't discover any devices.

These are command line error:

This is how I packaged it for NixOS:

{
  stdenv,
  lib,
  fetchFromGitHub,
  meson,
  pkg-config,
  cmake,
  ninja,
  wrapGAppsHook4,
  glib,
  glib-networking,
  libadwaita,
  gdk-pixbuf,
  desktop-file-utils,
  sqlite,
  gnutls,
  libportal-gtk4,
  evolution-data-server,
  json-glib,
  libpeas,
  gst_all_1,
  libsysprof-capture,
  libpulseaudio,
}:

stdenv.mkDerivation rec {
  pname = "valent";
  version = "393";

  src = fetchFromGitHub {
    owner = "andyholmes";
    repo = "${pname}";
    rev = "401fda881bc17d2424a621d41c9345f5e9e4f689";
    hash = "sha256-8TGl+U0tdR6jCTURATY86SxnjU6UiZUyMLrrmKPyvKw=";
    fetchSubmodules = true;
  };

  nativeBuildInputs = [
    meson
    pkg-config
    cmake
    ninja
    wrapGAppsHook4
    glib
    gdk-pixbuf
    desktop-file-utils
  ];

  buildInputs = [
    glib
    glib-networking
    libadwaita
    sqlite
    gnutls
    libportal-gtk4
    evolution-data-server
    json-glib
    libpeas
    gst_all_1.gst-plugins-bad
    gst_all_1.gst-plugins-base
    gst_all_1.gst-plugins-good
    gst_all_1.gst-plugins-ugly
    gst_all_1.gstreamer
    libsysprof-capture
    libpulseaudio
  ];

  meta = with lib; {
    description = " Connect, control and sync devices. ";
    homepage = "https://github.com/andyholmes/${pname}";
    license = licenses.gpl3Only;
    platforms = [ "x86_64-linux" ];
  };
}

Any kind of help is appreciated!

Thanks for packaging Valent for NixOS, I know that's a tough one sometimes 🙂

These are command line error:

These all look okay, actually. Some of these I just see all the time, while the others Valent is fine dealing with (missing portals, etc). My best guess is that this is a firewall/networking issue and Valent.

I recalled there is an option for the GSConnect package in Nix that uses programs.kdeconnect.enable. I really know very little about Nix, but is this an option for your system you set separate from the package?

Yes, you are probably right! I've just noticed that network.firewall.enable is true by default, so we need actually

        networking.firewall = rec {
          allowedTCPPortRanges = [ { from = 1714; to = 1764; } ];
          allowedUDPPortRanges = allowedTCPPortRanges;
        };

And this is what program.kdeconnect.enable does.

Awesome, let me know if that works :)

Tested and everything worked!
