Osiris is a C++ GUI toolkit, forked from Qt at version 2.3.2. It is fast, simple, and aesthetically lacking. However, it is still a highly functional toolkit and runs on modern Linux systems.
The primary use is providing a toolkit for MiDesktop (our fork of KDE1), due to licensing issues and some other issues with Qt version 1. However, it is a great way to bring other legacy applications back to life – both those using Qt1 and Qt2 (and there’s nothing stopping you from using it to write new applications either).
Getting Osiris
Osiris is packaged for Debian and Ubuntu. Distributions based on those may be able to use those packages, however, it has not been tested. Check out the instructions for installing MiDesktop to add the repository. Then, you can simply apt install osiris originator
