This tutorial shows one way to get KDE from trunk running. It consolidates info from several places, e.g.
#REDIRECT [[Getting_Started/Build|Building KDE]]
[http://developer.kde.org/build/trunk.html the official KDE developer pages]. The official pages may be updated without this page being updated too, so check there if you have problems.
 
See also: http://kdesvn-build.kde.org/
 
Throughout the tutorial the bash shell is used.
 
== Set up the development user account ==
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
 
== Prepare for software setup ==
 
Please look also in [[Getting Started/Increased Productivity in KDE4 with Scripts]] .
 
Add these lines to your shell's configuration file, e.g. {{path|~/.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=$KDEDIR \
-DCMAKE_BUILD_TYPE=debugfull $@ && make VERBOSE=1 && make install; }
 
 
Now either relogin or activate the settings with:
source {{path|~/.bashrc}}
 
== Set up D-Bus ==
Skip this if you have D-Bus <nowiki>>=</nowiki>0.93 installed.
wget http://dbus.freedesktop.org/releases/dbus/dbus-1.0.2.tar.gz
tar xvfz dbus-1.0.2.tar.gz
cd dbus-1.0.2/
./configure --disable-qt --disable-qt3 --prefix=$DBUSDIR \
--localstatedir=/var && make && make install
dbus-uuidgen --ensure
 
== Set up CMake ==
 
Skip this if you have [http://cmake.org/ CMake] >=2.4.3 installed.
 
The default prefix is {{path|/usr/local}}, make sure {{path|/usr/local/bin}} is in your <tt>$PATH</tt>.
 
cd
wget http://www.cmake.org/files/v2.4/cmake-2.4.5.tar.gz
tar zxf cmake-2.4.5.tar.gz
mkdir cmake-build
cd cmake-build
../cmake-2.4.5/bootstrap
make
sudo make install
 
== Set up Qt ==
cd
svn co svn://anonsvn.kde.org/home/kde/trunk/qt-copy
cd ~/qt-copy && ./apply_patches && \
./configure -qt-gif -no-exceptions -debug -fast \
-prefix $QTDIR -qdbus && make && make install
 
== Set up kdelibs ==
cd
svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs
mkdir kdelibs-build
cd kdelibs-build
cmakekde ../kdelibs
 
=== Install additional CMake modules ===
 
There are additional CMake modules in kdelibs that are necessary for building KDE applications. To install them:
cd
cd kdelibs/cmake/modules
cmake .
make install
 
You may need to do the last step as root (e.g. using su or sudo), depending on your system setup.
 
=== Troubleshooting ===
If you have problems compiling kdelibs, first make sure the following commands can be executed: aclocal, autoconf, autoheader, gcc, g++, pkg-config.
 
{{tip|If you get "Could NOT find GIF", install the devel package of <tt>libungif</tt> (the actual name may vary between operating systems).}}
 
If the problems persist, try the make-option <tt>--keep-going</tt>
 
== Set up 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
 
== Set up 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 kdebase:
* Make sure you have the <tt>libxss headers</tt> installed. (Usually you got undefined references on xscreensaver objects if you haven't those headers)
* <tt>which meinproc</tt> has to deliver {{path|/home/kde-devel/kde/bin/meinproc}}
* if cmakekde cannot find the path of kdepimlibs, edit the file /home/kde-devel/kdebase-build/CMakeCache.txt and manually set KDEPIMLIBS_INCLUDE_DIR:PATH=/home/kde-devel/kdepimlibs-build
* if you get an error saying "Please set the following variables: X11_XTest_LIB (ADVANCED)", install the devel package of <tt>Xtst</tt>. On some systems, this is packaged separately from <tt>xext</tt> and called <tt>x11proto-xext-dev</tt> or <tt>libxtst-dev</tt>. You may also need to remove the CMakeCache.txt file in the build dir after installing the package.
 
== Success! ==
 
You are now ready to start building other svn modules in the same fashion as you built kdebase, running and testing KDE4 or writing your own patches and applications.
 
See the [[Getting Started/Set up KDE 4 for development|Starting a KDE4 Environment and Applications]] tutorial for how to start working on your new KDE4 installation.
