Getting Started/Build/KDE4
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
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 KDEDIRS=$KDEDIR
export DBUSDIR=$KDEDIR
export PKG_CONFIG_PATH=$DBUSDIR/lib/pkgconfig:\
$PKG_CONFIG_PATH
export PATH=$QTDIR/bin:$KDEDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:$KDEDIR/lib:$LD_LIBRARY_PATH
alias dbusstart="eval `PATH=$DBUSDIR/bin \
$DBUSDIR/bin/dbus-launch --auto-syntax`"
function cmakekde { cmake -DCMAKE_INSTALL_PREFIX=$HOME/kde \
-DCMAKE_BUILD_TYPE=debugfull $@ && make VERBOSE=1 && make install}
Check out the software
svn co svn://anonsvn.kde.org/home/kde/trunk/qt-copy svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs wget http://www.cmake.org/files/v2.4/cmake-2.4.3.tar.gz wget http://dbus.freedesktop.org/releases/dbus-0.91.tar.gz
Build DBus
tar xvfz dbus-0.91.tar.gz cd dbus-0.91/ ./configure --disable-qt --disable-qt3 --prefix=$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.
dbusstart
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 ../cmake-2.4.3/bootstrap make sudo make install
Build KDElibs
cd ~/ mkdir kdelibs_build cd kdelibs_build cmakekde ../kdelibs
Troubleshooting
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
--keep-going
Build kdepimlibs
Before KDEBase you need to install kdepimlibs
cd svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdepimlibs mkdir kdepimlibs-build cd kdepimlibs-build cmakekde ../kdepimlibs
Troubleshooting
To compile against kdelibs (not the snapshot) add
set(KDE4_IGNORE_DONTPORT TRUE)
to the CMakeLists.txt before 'find_package(KDE4 REQUIRED)'
Build KDEbase
You may need KDEbase for some kioslaves.
cd svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdebase mkdir kdebase-build cd kdebase-build cmakekde ../kdebase
Troubleshooting
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 startkde
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 kde-devel@localhost kwrite
