openSUSE has a very strong and active KDE team with a lot of information on their own wiki:
Use the following commands to install the needed packages:
zypper install alsa-devel automoc4 avahi-devel patch cups-devel kde4-filesystem \ libbz2-devel avahi-compat-mDNSResponder-devel hal-devel xorg-x11-devel \ libQtWebKit-devel libxml2-devel kdesdk4 clucene-core-devel boost-devel \ libjpeg-devel liblrdf-devel libpng-devel libxslt-devel libredland-devel \ Mesa-devel giflib-devel subversion gcc-c++ gmp-devel xine-devel \ libgpgme-devel pcre-devel dbus-1-devel libqt4-devel cmake git \ doxygen polkit-devel docbook-xsl-stylesheets cyrus-sasl-devel libical-devel
This section describes how you can get kde to compile so that you can log in graphically (using kdm, the KDE display manager) and call konqueror (contained in KDEBASE, KDE's base package).
You can install kdesupport and its dependencies from SUSE by adding the KDE:Distro:Stable repository from the openSUSE Build Service to your repositories. For openSUSE 12.1 add this Repository to YaST/zypper:
For older versions of openSUSE do:
su zypper ar -f http://download.opensuse.org/repositories/KDE:/Distro:/Stable/[YOUR SUSE LINUX VERSION]
Now install kdesupport from openSUSE:
zypper install libqca2-devel libsoprano-devel libqimageblitz-devel strigi-devel
Please remember to skip any instructions from Getting_Started/Build that refer to kdesupport. Start to compile with kdelibs.
openSUSE, via its Build Service, provides a so-called unstable repository which contains weekly snapshots from KDE SVN trunk. These allow you to run a system install of unstable, but does not allow you to keep a stable system install while testing unstable in parallel.
You need a supported openSUSE version, that is, at the time of writing, openSUSE 11.0, 11.1, 11.2 or openSUSE Factory (the always-on-development branch of openSUSE).
You can either use the one-click-install, which can provide pre-arranged sets of packages, namely the basic system (KDE4-BASIS), games (KDE4-GAMES), or a complete development setup (KDE4-DEVEL), or add the repository manually and perform an installation from the command line.
Depending on the openSUSE version use, there are different one-click installs:
Click on the relevant link and YaST will set up the repositories and install the required packages.
Add the repository. To do so, enter as root
where YOUR_SUSE_VERSION is either openSUSE_10.3, openSUSE_11.0, openSUSE_11.1, or openSUSE_Factory depending on what you are running.
After that, refresh the package index and update the packages to the unstable version:
zypper ref && zypper up
The Desktop repository does not include everything from KDE: for example, Amarok 2 is not present there. To add even more applications, including extragear ones, you need to use the KDE:KDE4:UNSTABLE:Extra_Apps repository.
Alternatively, using zypper:
zypper ar http://download.opensuse.org/repositories/KDE:/KDE4:/UNSTABLE:/Extra-Apps/YOUR_SUSE_VERSION/
followed by the installation the packages you need, for example Amarok 2:
zypper in amarok
