In comparison to the installation process on [[Development/Languages/Ruby/Ruby-Qt/KDE Book/Installation/Installation on Windows|Microsoft Windows]] or [[Development/Languages/Ruby/Ruby-Qt/KDE Book/Installation/Installation on Mac OS|Apple Mac OS]] you have to deal with the fact, that there are a lot of different Linux-based operating systems. So there are also different ways to setup your environment for kdebindings.

First you should check before starting to install something if your [http://en.wikipedia.org/wiki/Linux_distribution  Linux distribution] has ruby and/or the bindings preinstalled.

= Test Installation =

Start a shell on your Linux system and type and try to get the version of your ruby installation. In the case of a working ruby installation you get something like this.

<code bash>
> ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]
</code>

Maybe the Qt/KDE bindings are installed, too. For a quick check, enter <tt>irb</tt> in a shell to start the interactive ruby-shell. Try to load the bindings.

<code ruby>
require "Qt4"
=> true
require "korundum4"
=> true
</code>

You can load bindings for KDE4 (korundum4) or only Qt4 by a <tt>require</tt>. Later you won't need to load Qt4 first when using KDE4, because on requiring KDE4 everything needed is loaded automatically.

If you got it so far you seems to have a working environment.

== Installation of ruby ==

If you haven't ruby installed, you have two different ways to get it.

# using the distribution package manager to install ruby automatically
# install ruby manually from source.

I recommend the first way.
