This describes how to use a virtual machine for building the latest KDE from sources.

[edit] Virtual Machine Setup

Create a virtual machine, e.g. using VirtualBox. Regarding harddisk: KDE 4 fits into 10 GB, however I recommend 40GB, one partition. Regarding RAM: You will need at least 1GB ram for the virtual machine, of course more is better.

You will need to set your SUSE CD as your virtual machine's cdrom.

[edit] setup for SSH

To be able to log in to your VM using ssh, stop and disable the firewall:

rcSuSEfirewall2 stop
chkconfig SuSEfirewall2_setup off
chkconfig SuSEfirewall2_init off
/etc/init.d/sshd start
chkconfig sshd on

Inside the VM, install some needed packages:

yast -i libqt4-devel pcre-devel libxslt-devel libxml2-devel docbook-xsl-stylesheets git cyrus-sasl-devel libiodbc-devel \
libdbusmenu-qt-devel giflib-devel strigi-devel libQtWebKit-devel libqimageblitz-devel libical-devel libgpgme-devel \
boost-devel libqjson-devel libredland-devel xcb-util-image-devel

Now it is time to do a snapshot or clone from your VM.

You will be able to return to this machine state whenever you want.

[edit] a few more steps

Open a console as root

su -

[edit] on an x64 distribution

If and only if you have a /lib64 path, you are on an x64 distribution. Make sure you have the needed environment variables and alias set by having a file /root/.bashrc.

cd
cat >.bashrc<<EOF 
export KDEDIR=/usr/local         
alias cmakekde="cmake . -DCMAKE_INSTALL_PREFIX=\$KDEDIR -DLIB_SUFFIX=64 -DCMAKE_BUILD_TYPE=debugfull && make -j8 && make install"
alias cmakekdelibs="cmake ../kdelibs -DCMAKE_INSTALL_PREFIX=\$KDEDIR -DLIB_SUFFIX=64 -DCMAKE_BUILD_TYPE=debugfull && make -j8 && make install"
alias makeqt="./configure -dbus -openssl -plugin-sql-mysql -libdir /usr/lib64 -prefix /usr && make -j8 && make install"
export QTDIR=/usr
EOF
cat >.gitconfig<<EOF
[url "git://anongit.kde.org/"]
    insteadOf = kde:
[url "ssh://git@git.kde.org/"]
    pushInsteadOf = kde:
EOF

Now activate this file

. /root/.bashrc

[edit] on another distribution (incl 32bit)

Make sure you have the needed environment variables and alias set by having a file /root/.bashrc.

cd
cat >.bashrc<<EOF
export KDEDIR=/usr/local         
alias cmakekde="cmake . -DCMAKE_INSTALL_PREFIX=\$KDEDIR -DCMAKE_BUILD_TYPE=debugfull && make -j8 && make install"
alias cmakekdelibs="cmake ../kdelibs -DCMAKE_INSTALL_PREFIX=\$KDEDIR -DCMAKE_BUILD_TYPE=debugfull && make -j8 && make install"
alias makeqt="./configure -dbus -openssl -plugin-sql-mysql -prefix /usr && make -j8 && make install"
export QTDIR=/usr
EOF
cat >.gitconfig<<EOF
[url "git://anongit.kde.org/"]
    insteadOf = kde:
[url "ssh://git@git.kde.org/"]
    pushInsteadOf = kde:
EOF

Now activate this file

. /root/.bashrc

[edit] Aquire and Build KDE as root

If something fails you may need to make clean and rm CMakeCache.

[edit] cmake

Install the latest version of cmake:

cd
wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz
tar xvzf cmake-2.8.10.2.tar.gz
cd cmake-2.8.10.2
./configure && make -j4 && make install

[edit] automoc

automoc is needed for akonadi.

cd
git clone kde:automoc
cd automoc
cmakekde

[edit] libattica

cd
git clone kde:attica
cd attica
cmakekde

[edit] shared desktop ontologies

shared desktop ontologies is needed by kdepimlibs in order to build Nepomuk (which is a part of kdelibs)

cd
wget http://downloads.sourceforge.net/project/oscaf/shared-desktop-ontologies/0.10.0/shared-desktop-ontologies-0.10.0.tar.bz2
tar xvjf shared-desktop-ontologies-0.10.0.tar.bz2
cd shared-desktop-ontologies-0.10.0/
cmake . && make && make install

[edit] soprano

cd
git clone kde:soprano
cd soprano
cmakekde

[edit] phonon

Phonon is needed for kdebase-runtime

cd
git clone kde:phonon
cd phonon
cmakekde

[edit] akonadi

Akonadi keeps personal information management data in a mysql database. It is needed for KDEPIMLIBS.

cd
git clone kde:akonadi
cd akonadi
cmakekde

[edit] kdelibs

KDELIBS requires an out-of-source build, that is why it is more complicated to build:

cd
git clone kde:kdelibs
mkdir kdelibs-build
cd kdelibs-build
cmakekdelibs

Verify it has been correctly installed - the following must be possible:

kde4-config --prefix
/usr/local

[edit] nepomuk-core

cd
git clone kde:nepomuk-core
cd nepomuk-core
cmakekde

[edit] kdepimlibs

kdepimlibs is needed for kde-runtime.

cd
git clone kde:kdepimlibs
cd kdepimlibs
cmakekde

[edit] kactivities

kactivities is needed for kde-workspace.

cd
git clone kde:kactivities
cd kactivities
cmakekde

[edit] kdebase

cd 
git clone kde:kde-baseapps
git clone kde:konsole
git clone kde:kde-workspace
git clone kde:kde-runtime 
cd kde-baseapps
cmakekde
cd
cd konsole
cmakekde
cd
cd kde-workspace
cmakekde
cd
cd kde-runtime
cmakekde

[edit] Next step

Now you can start developing. Best, install QtCreator:

yast -i qt-creator

And learn how to create a new KDE project or import an existing one by reading qtcreator.
