Anyone successfully run Vuze on NixOS?

Hi,

I’ve been using Ktorrent, the default KDE torrent client, for a couple of years but its performance is not great. Not sure if I’m doing anything wrong but as long as Ktorrent is downloadng a few more (3+) torrents it becomes really laggy and sometimes just refuses to respond to mouse clicks, etc. So I’ve been searching for an alternative and found Vuze.

I saw there is a package available in nixpkgs so I installed it. After installation, I didn’t find any GUI available. When trying to start Vuze using command vuze, it gave me the following error:

file:/nix/store/k63zkarn86cyj20vq95yn8sr8b733wm8-vuze-5750/share/java/Vuze_5750-00.jar ; file:/nix/store/v6ys8rpckw8i8mwxcv8pymqyh2w4g1wb-swt-4.5/jars/swt.jar ; file:/home/rollschild/

Does anyone know what this message actually means? Looks like the package was compiled using a Java runtime that is too new?

Any help would be much appreciated! Thanks!

Not what you are asking for, but I’ve been using deluge for ages.

It is run by a newer Java version I would guess or you miss a locale on your machine.

Give Transmission a try. It has clients for KDE and GTK-based DE’s, and it’s in the repositories so it’s easy to try out or install.
