#REDIRECT [[Getting_Started/Build|Building KDE]]
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 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 [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.
 
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.
 
which meinproc
 
has to deliver
 
/home/kde-devel/kde
 
 
 
==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:
 
 
kwrite
