Getting Started/Build/KDE4
This article shows how to download, build, install and start KDE 4 from subversion. It consolidates howtos from various sites, e.g. the old KDE developer pages. 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 passwd kde-devel chown kde-devel:kde-devel /home/kde-devel 2>/dev/null || \ chown kde-devel:users /home/kde-devel
Switch to the user kde-devel: (the dash also changes to the new home directory)
su - kde-devel
Set Environment Variables
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
## Uncomment if dbus doesn't work
#alias dbusstart="eval `PATH=$DBUSDIR/bin \
#$DBUSDIR/bin/dbus-launch --auto-syntax`"
function cmakekde { cmake -DCMAKE_INSTALL_PREFIX=$HOME/kde \
-DCMAKE_BUILD_TYPE=debugfull $@ && make VERBOSE=1 && make install; }
Check out the software
svn co svn://anonsvn.kde.org/home/kde/trunk/qt-copy svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs wget http://www.cmake.org/files/v2.4/cmake-2.4.3.tar.gz wget http://dbus.freedesktop.org/releases/dbus/dbus-0.94.tar.gz
Build D-Bus
tar xvfz dbus-0.94.tar.gz cd dbus-0.94/ ./configure --disable-qt --disable-qt3 --prefix=$DBUSDIR \ --localstatedir=/var && make && make install
Build Qt
cd ~/qt-copy && \ ./configure -qt-gif -no-exceptions -debug -fast \ -prefix $QTDIR -qdbus && make && make install
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 headersinstalled. (Usually you got undefined references on xscreensaver objects if you haven't those headers) which meinprochas to deliver /home/kde-devel/kde/bin/meinproc
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
