When i run following code:

require 'uinput/keyboard'

begin
    keymap = Uinput::Keyboard.keymap(rules: 'evdev', model: 'pc104', layout: 'de', variant: 'nodeadkeys')
    keyboard = Uinput::Keyboard.new(keymap)

    sleep 1 # to give linux time to setup the new device

    # While pasting this code into irb
    keyboard.type('Time.now')   # types 'Time.now'
    keyboard.tap(:Return)       # presses the Return key and returns the timestamp
ensure
    keyboard.destroy if keyboard
end

get following error:

That's because you need the xkbcommon library for your linux distribution.

zw963 commented 8 years ago

i have this package installed, though the name is not exactly same.

rpm -ql libxkbcommon-x11-0
/usr/lib64/libxkbcommon-x11.so.0
/usr/lib64/libxkbcommon-x11.so.0.0.0
/usr/share/doc/packages/libxkbcommon-x11-0
/usr/share/doc/packages/libxkbcommon-x11-0/COPYING
/usr/share/doc/packages/libxkbcommon-x11-0/NEWS

does i need recreate a new symbolic link?

christopheraue commented 8 years ago

No, that's not the correct lib.

zw963 commented 8 years ago

after a search in openSUSE 42.1 with zypper(package manager) I can found the only package is this.

 rpm -ql libxkbcommon0
/usr/lib64/libxkbcommon.so.0
/usr/lib64/libxkbcommon.so.0.0.0
/usr/share/doc/packages/libxkbcommon0
/usr/share/doc/packages/libxkbcommon0/COPYING
/usr/share/doc/packages/libxkbcommon0/NEWS

and i recreate it will a new symbolic link as need, it worked.
