Is there any prerequisites before using this?

I am using Linux and using this package out of the box. Here is what I did.

1. Install libevdev-tools and libudev-dev.
2. Add Gradle dependencies
3. Run the test code:

        final ControllerManager controllerManager = new ControllerManager();
        controllerManager.initSDLGamepad();
        final int numControllers = controllerManager.getNumControllers();
        System.out.println(String.format("There are %d connected controllers", numControllers));

In the last step, I got this message before the application exited

NATIVE METHOD: loading from "/tmp/8117474319126184219.tmp"
result 74 Failed loading udev_device_get_action: /tmp/jnigen/375939362/libsdl2gdx64.so: undefined symbol: _udev_device_get_action

Is there any steps that I am missing?

It’s not you, I have reproduced this. Something is messed up with the Linux build. I will investigate.
