it builds, but does not run on my system.
no error or anything, just exits.

Is there something i'm missing?

Thanks for testing! Made a quick change since I just realized plex-desktop and plex-htpc use the same ~/.local/share path but that may not fix the issue you're seeing. Does plex-desktop have the same launching issue?

EDIT: I've cleared out my ~/.local/share/plex folder to make sure things work with a fresh instance and there doesn't seem to be anything wrong. Does it log anything to ~/.local/share/plex/Logs/Plex HTPC.log?

ah yeah, same error for both

ERROR - Fatal error: qrc:/views/WebWindow.qml: module "gtk2" is not installed

Got it. Thanks for the report. Maybe we can simply add gtk2 to the buildFHSEnv. I'd be curious if adding something like

  # Plex needs this to login/click on links.
  xdg.portal = {
    enable = true;
    extraPortals = [ pkgs.xdg-desktop-portal-gtk ];
    xdgOpenUsePortal = true;
  };

to your nixos config works too. Will look into this a little more and see if I can find something.

Thank you for this pr, I have desired to be able to run this for about 8 or so months now and was never able to get it to work myself.
Also, stylix breaks this package, the QT_STYLE_OVERRIDE env var is set to kvantum, which for whatever reason panics both plex-htpc, as well as plex-desktop.
Setting it to "default" worked for me.

Added unset QT_QPA_PLATFORM QT_STYLE_OVERRIDE to fix this. If people are certain that they want this set to something, overriding extraEnv should still works:

plex-desktop.override {
  extraEnv = { QT_QPA_PLATFORM="wayland"; };
}

Reproduced with QT_STYLE_OVERRIDE=gtk result/bin/plex-htpc and this now no longer causes plex to crash as before.

Lets gooo! @detroyejr thank you! I am so hyped to finally be able to use this! I know others who are hyped for this too.

ive been waiting on this for a while @detroyejr thanks for this pr

Fixed two build issues after bumping including what was addressed in #418546. Runs fine and there aren't any other issues I've spotted. If anyone has feedback, just let me know! I'll make another request in the review channel soon and maybe we can get this merged.

Bump.
Really want to remove the extra nixpkgs from my config.

Thanks for the review! There's an open issue I plan to address (#434341) if it lands on the main branch before this is merged. Otherwise, I'll open a PR against staging-next like we did for #434467.
