This article shows how to download, build, install and start KDE 4 from subversion. It consolidates howtos from various sites, e.g.
#REDIRECT [[Getting_Started/Build|Building KDE]]
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
 
Switch to the user kde-devel:
su - kde-devel
 
== Set Environment Variables ==
You have to add some environment variables - add these lines to <code>~/.bashrc</code>.
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-0.92.tar.gz
 
== Build D-Bus ==
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. <code>kxml_compiler</code> based file processing in kdepim:
dbusstart
 
== 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 <code>/usr/local</code>, make sure <code>/usr/local/bin</code> is in your <code>$PATH</code>.
 
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 <code>libungif</code> (the actual name may vary on distribution).
 
If the problems persist, try the make-option <code>--keep-going</code>
 
== 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 <code>CMakeLists.txt</code> before <code>find_package(KDE4 REQUIRED)</code>
 
== 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 <code>libxss headers</code> installed. (Usually you got undefined references on xscreensaver objects if you haven't those headers)
* <code>which meinproc</code> has to deliver <code>/home/kde-devel/kde/bin/meinproc</code>
 
== 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
