Introduction to libevdev

The libevdev package provides functions to communicate with the evdev interface for generic input. Meanwhile, it also abstracts details such as ioctls in favor of providing a simple frontend for input handling.

Kernel Configuration

Enable the following options in the kernel configuration and recompile the kernel if necessary: 

Device Drivers --->
  Input device support --->
    -*-   Generic input layer (needed for keyboard, mouse, ...)          [INPUT]
    <*/M>   Event interface                                        [INPUT_EVDEV]

Installation of libevdev

Install libevdev by running the following commands: 

mkdir build &&
cd    build &&

meson setup ..                  \
      --prefix=/usr             \
      --buildtype=release       \
      -D documentation=disabled \
      -D tests=disabled &&

ninja

Now, as the root user: 

ninja install

Note

Inspect meson_options.txt or meson.options for a full list of options.

-D tests=disabled: This switch disables building tests as they depend on Check.
