== Abstract ==
 
 
 
This tutorial shows one way to get KDE from trunk running. It consolidates info from several places, e.g.
 
[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.
 
 
 
{{note|Throughout the tutorial the bash shell is used.}}
 
 
 
== Set up the development user account ==
 
<code bash>
 
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
 
</code>
 
 
 
Switch to the user kde-devel: (the dash also changes to the new home directory)
 
<code bash>
 
su - kde-devel
 
</code>
 
 
 
== The kde-devel User's Shell ==
 
 
 
On some systems a new user is configured by default to use /bin/sh. If this is not the case on your system, you can skip this section. Using /bin/sh can be very inconvenient to work with and you may want to change it to /bin/bash or another shell.
 
 
 
{{note|To change the user's default shell you will need write access to /etc/passwd. Usually this means running a command as root.}}
 
 
 
If your system comes with the <tt>usermod</tt> application you can run the following command as root: <tt>usermod -s /bin/bash</tt>.
 
 
 
Another option is to use the <tt>vipw</tt> application as root to safely edit your /etc/passwd. Locate 'kde-devel' in the the file. Change '/bin/sh' at the end of the line to read '/bin/bash', save your changes and exit.
 
 
 
The new shell will be started automatically when you log in as the kde-devel user again.
 
 
 
== 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}}.
 
<code bash>
 
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 [email protected] && make VERBOSE=1 && make install; }
 
</code>
 
 
 
Now either relogin or activate the settings with:
 
<code bash>
 
source {{path|~/.bashrc}}
 
</code>
 
 
 
== 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 checkout 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
 
 
 
=== Additional KDE-specific CMake modules ===
 
 
 
There are additional CMake modules in {{path|kdelibs/cmake/modules/}} that are necessary for building KDE4 applications. These will be installed for your when  kdelibs itself is installed.
 
 
 
=== Troubleshooting ===
 
If you have problems compiling kdelibs, first make sure the following commands can be executed: 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).}}{{tip|In order to avoid compilation problems, GCC should be at least of version 4.1. The minimum supported compiler is not yet determined at the time of writing this.}}
 
 
 
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.
 
* the same for "X11_Xinerama_LIB (ADVANCED)" where you will need the devel package for <tt>xinerama</tt>.
 
 
 
== 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.
