The code is hosted by the KDE project. You can obtain your local copy by running following command:
$ git clone git://anongit.kde.org/trojita
If you prefer to work with something more official, you can try the latest release, 0.7 -- download it from SourceForge (GPG signature).
You will need the development version of these packages if you are building yourself.
Go to the directory created by Git (or unpacked from the archive) and run:
$ mkdir _build; cd _build
$ cmake ..
$ make -j4
$ ctest -j 4 --output-on-failure
After successful compilation, you can run Trojitá from the build directory:
$ ./trojita
We used to ship prebuilt binaries of Trojitá for various Linux distributions and Windows but due to a lack of maintenance, they are no longer available.
Bug tracking happens in KDE Bugzilla (see list of open bugreports). If you encounter any problem in Trojitá, please file a bug. Wishlist items belong to the same place.
Previously, Trojitá was using Redmine for bug tracking, and some of the bugs are still tracked in the old tracker.
Trojitá's IRC channel #trojita is hosted on the Libera network.
There's a mailing list at trojita@lists.flaska.net, archived by GMane. To subscribe, write a mail to trojita+subscribe@lists.flaska.net, posts from addresses which are not subscribed have to wait for moderation. The issue tracker or the mailing list is the preferred way for reporting bugs and requesting features, while the IRC channel works well for general questions. You can also of course mail the author directly.
If you happen to like Trojita and would like to express your liking in cash, the project accepts donations over SourceForge/PayPal.
