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
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:
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.
Previously, Trojitá was using Redmine for bug tracking, and some of the bugs are still tracked in the old tracker.
There's a mailing list at firstname.lastname@example.org, archived by GMane. To subscribe, write a mail to email@example.com, 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.
