Build instructions

This article shows how to download, build, install and start KDE 4 from subversion. It consolidates howtos from various sites, e.g. http://developer.kde.org/build/compile_cvs.html. This topic shows one way that works. It does not intend to explain the obvious background behind it.

To reduce complexity, we use the bash-shell (standard) throughout the tutorial.

Become the user kde-devel

useradd kde-devel
mkdir /home/kde-devel
chown kde-devel:kde-devel /home/kde-devel 2>/dev/null || chown kde-devel:users /home/kde-devel{CODE}

Change to the user kde-devel:

su - kde-devel

Setting the environment

You have to add some environment variables - add these lines to ~/.bashrc.

export YACC='byacc -d'
export QTDIR=$HOME/qt-unstable
export KDEDIR=$HOME/kde
export PKG_CONFIG_PATH=$DBUSDIR/lib/pkgconfig:\ 
export PATH=$QTDIR/bin:$KDEDIR/bin:$PATH
alias dbusstart="eval `PATH=$DBUSDIR/bin \
$DBUSDIR/bin/dbus-launch --auto-syntax`"
function cmakekde { cmake -DCMAKE_INSTALL_PREFIX=$HOME/kde \
-DCMAKE_BUILD_TYPE=debugfull [email protected] && make VERBOSE=1 && make install}

Check out the software

svn co svn://anonsvn.kde.org/home/kde/trunk/qt-copy
svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs
wget http://www.cmake.org/files/v2.4/cmake-2.4.3.tar.gz
wget http://dbus.freedesktop.org/releases/dbus-0.91.tar.gz

Build DBus

tar xvfz dbus-0.91.tar.gz
cd dbus-0.91/
./configure --disable-qt --disable-qt3 --prefix=$DBUSDIR \
--localstatedir=/var && make && make install

__Make sure the dbus session is running__ Otherwise some parts of the build will fail, e.g. kxml_compiler based file processing in kdepim.


Build Qt

cd ~/qt-copy && \
./configure -qt-gif -no-exceptions -debug -fast \
-prefix $QTDIR -qdbus && make && make install{CODE}

Build and install CMake

The default prefix is /usr/local, make sure /usr/local/bin is in your PATH.

tar zxf cmake-2.4.3.tar.gz
mkdir cmake-build
cd cmake-build
sudo make install

Build KDElibs

cd ~/
mkdir kdelibs_build
cd kdelibs_build
cmakekde ../kdelibs


If you have problems compiling this, first make sure the following commands can be executed: aclocal, autoconf, autoheader, gcc, g++, pkg-config.

__Note :__ If you get "Could NOT find GIF", install the devel package of libungif (the actual name may vary on distribution).

If the problems persist, try the make-option


Build kdepimlibs

Before KDEBase you need to install kdepimlibs

svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdepimlibs
mkdir kdepimlibs-build
cd kdepimlibs-build
cmakekde ../kdepimlibs


To compile against kdelibs (not the snapshot) add


to the CMakeLists.txt before 'find_package(KDE4 REQUIRED)'

Build KDEbase

You may need KDEbase for some kioslaves.

svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdebase
mkdir kdebase-build
cd kdebase-build
cmakekde ../kdebase


If you have troubles compiling this:

  • Make sure you have the libxss headers installed. (Usually you got undefined references on xscreensaver objects if you haven't those headers)
  • Make sure you compiled and installed kdelibs4_snapshot including the kdoctools.

Start KDE 4 programs

To start the desktop environment itself, do:

X :1 & export DISPLAY=:1

Maybe you are logged in as your normal user (not kde-devel), want to stay in your current environment (KDE 3.5, gnome, whatever) and start a KDE 4 program. To start only kwrite from KDE 4, do:

ssh -X [email protected]
