Turns your input devices into joysticks by converting relative axes into absolute ones. Additionally, some options let you create a modified copy of your relative device.
- Use a relative input device as a joystick.
- Bypass an issue causing your device to report its axis are relative when they are absolutes (see the wiki page on 3DConnexion devices for example), this can be required by some librairies (such as Simple DirectMedial Layer - SDL) for your device to be recognized.
- Change what controls which axis (still has to be on the same input device).
- Invert an axis.
- CMake (>= 3.0)
- libevdev
See the related wiki page on how to set up relabsd, and the one on how to create a virtual device.
(Using Grumpel's sdl-jstest)
Note that the real device (a 3Dconnexion SpaceNavigator, that's a 6DOF device) was made to report itself as being a joystick so it could be see by SDL. This is not required (only the virtual device has to).

Your input device should be listed in /dev/input. You can use commands such as relabsd -? /dev/input/event8 to obtain information on the devices found there.
If you are using a 3DConnexion device and not finding it in /dev/input, read this wiki page.
