< Getting Started | Build | KDE4

This describes how to set up a virtual machine running KDE from trunk on Linux.

Throughout the tutorial we use VMWare for virtualization and SUSE Linux 11.1 as distribution. Other combinations should work same or similar.

We use VMWare because I think compiling is faster with it.

[edit] Install

Create a VMWare virtual machine. KDE 4 fits into 10 GB harddisk space. But as you start getting fun out of it, you will be happy about additional space. I recommend 40GB, one partition. In your VM, install SUSE Linux 11.1. Choose Gnome as desktop environment so you will have to un-install less KDE packages. All KDE packages would need to be uninstalled because they depend on the old QT 4.4.

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

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 taglib-devel
yast -i libmysqlclient-devel

Now you need to uninstall QT 4.4 because for the latest KDE, QT 4.5 is needed:

rpm -e libqt4 libQtWebKit4 python-qt4 libqdialogsolver1 libqt4-x11 libqt4-qt3support \n
libqt4-x11 sax2-libsax-perl yast2-x11 sax2-libsax sax2-ident sax2-gui sax2 libqt4-sql \n
yast2-qt yast2-qt-pkg libqt4-sql-mysql hplip

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

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

If and only if you have a /lib64 path, you are on an x64 distribution.

[edit] on an x64 distribution

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

cat >.bashrc<<EOF 
export KDEDIR=/usr/local         
alias cmakekde="cmake . -DCMAKE_INSTALL_PREFIX=\$KDEDIR -DLIB_SUFFIX=64 -DCMAKE_BUILD_TYPE=debugfull && make -j2 && make install"
alias cmakekdelibs="cmake ../kdelibs -DCMAKE_INSTALL_PREFIX=\$KDEDIR -DLIB_SUFFIX=64 -DCMAKE_BUILD_TYPE=debugfull && make -j2 && make install"
EOF

Now activate this file

. /root/.bashrc

[edit] on another distribution

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

cat >.bashrc<<EOF
export KDEDIR=/usr/local         
alias cmakekde="cmake . -DCMAKE_INSTALL_PREFIX=\$KDEDIR -DCMAKE_BUILD_TYPE=debugfull && make -j2 && make install"
alias cmakekdelibs="cmake ../kdelibs -DCMAKE_INSTALL_PREFIX=\$KDEDIR -DCMAKE_BUILD_TYPE=debugfull && make -j2 && make install"
EOF

Now activate this file

. /root/.bashrc

[edit] Compile

[edit] cmake

You need cmake 2.6.2, so go to http://www.cmake.org/cmake/resources/software.html and download the latest version, in this example we choose 2.6.2:

cd
wget http://www.cmake.org/files/v2.6/cmake-2.6.2.tar.gz
tar xvzf cmake-2.6.2.tar.gz
cd cmake-2.6.2
./bootstrap && make -j2 && make install

[edit] Qt

As of 2009, QT 4.5 is needed for building KDE. So we need to compile it on our own. Before, remove all old Qt 4.4 packages.

Note: The compile lasts 80 minutes on a 2x2.4 GHz machine.

cd
svn co https://svn.kde.org/home/kde/trunk/qt-copy
cd qt-copy
./apply_patches && yes yes | ./configure -dbus -openssl -plugin-sql-mysql -prefix /usr && make -j2 && make install

[edit] libical

For kdepimlibs, libical 0.42 or higher is needed

cd 
wget http://heanet.dl.sourceforge.net/sourceforge/freeassociation/libical-0.43.tar.gz
tar xvzf libical-0.43.tar.gz
cd libical-0.43
./configure && make -j2 && make install

[edit] kdesupport

cd
svn co https://svn.kde.org/home/kde/trunk/kdesupport
cd kdesupport
cmakekde

[edit] kdelibs

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

cd
svn co https://svn.kde.org/home/kde/trunk/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] kdepimlibs

cd
svn co https://svn.kde.org/home/kde/trunk/KDE/kdepimlibs
cd kdepimlibs
cmakekde

[edit] kdebase

cd 
svn co https://svn.kde.org/home/kde/trunk/KDE/kdebase
cd kdebase
cmakekde

[edit] Config

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 some SUSE-specific paths in /etc/init.d/xdm:

KDM_BIN=/usr/local/bin/kdm
KDM4_BIN=/usr/local/bin/kdm
