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

Contents

Virtual Machine Setup

Create a virtual machine, e.g. using VMware Player. KDE 4 fits into 10 GB minimum, I recommend 40GB, one partition. As much ram as you can spare, You will need at least 1GB ram for the virtual machine, 4 doesnt hurt if you have it, install SUSE Linux 11.4.

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

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 libopenssl-devel subversion gcc-c++ boost-devel libbz2-devel libxml2-devel pcre-devel \
libxslt-devel giflib-devel libjpeg-devel libgpgme-devel xorg-x11-devel glib2-devel libpng-devel \
make dbus-1-devel strigi-devel \
libmysqlclient-devel libmysqld-devel cmake libical-devel git cyrus-sasl-devel libsoprano-devel \
libqt4-devel docbook-xsl-stylesheets libQtWebKit-devel phonon-devel libqimageblitz-devel doxygen
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.

a few more steps

Open a console as root

su -

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

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

Aquire and Build KDE as root

If something fails you may need to make clean.

automoc

automoc is needed for akonadi.

cd
git clone kde:automoc
cd automoc
cmakekde

akonadi

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

cd
git clone kde:akonadi
cd akonadi
cmakekde

libattica

cd
git clone kde:attica
cd attica
cmakekde

dbusmenuqt

cd
git clone git://gitorious.org/dbusmenu/dbusmenu-qt.git
cd dbusmenu-qt
cmakekde

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/0.8/shared-desktop-ontologies-0.8.0.tar.bz2
bunzip2 shared-desktop-ontologies-0.8.0.tar.bz2
tar xvf shared-desktop-ontologies-0.8.0.tar
cd shared-desktop-ontologies-0.8.0/
cmake . && make && make install

phonon

Phonon is needed for kdebase-runtime

cd
git clone git://anongit.kde.org/phonon
cd phonon
cmakekde

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

kactivities

kactivities is needed for kde-workspace.

cd
git clone kde:kactivities
cd kactivities
cmakekde

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

Config

First allow root login. You will need it as you do not have another login:

sed -i "s/AllowRootLogin.*/AllowRootLogin=true/g" /usr/local/share/config/kdm/kdmrc

Now stop your running display manager:

/etc/init.d/xdm stop

And start your self-compiled display manager:

kdm

To enable automated startup of your kdm, you need to change a SUSE-specific path in /etc/init.d/xdm:

KDM4_BIN=/usr/local/bin/kdm
