    This tutorial shows one way to get KDE from trunk running. It consolidates info from several places, e.g. the old KDE developer pages.

    See also: http://kdesvn-build.kde.org/

    Throughout the tutorial the bash shell (default on Linux) 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

    Add these lines to your shell's configuration file, e.g. ~/.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; }
    


    Activate these settings with: (or logout and login again)

    source ~/.bashrc
    

    Set up D-Bus

    Skip this if you have D-Bus >=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-0.1.0.2/
    ./configure --disable-qt --disable-qt3 --prefix=$DBUSDIR \
    --localstatedir=/var && make && make install
    dbus-uuidgen --ensure
    

    Set up CMake

    CMake is the build system tool used in KDE4. It replaced autotools used in previous KDE versions because of simplicity, speed and better cross-platform compatibility.

    Your operating system may provide CMake as an optional package. Check to see if there is a package of CMake 2.4.3 or better available and if so install that. If not, then you can download CMake from the CMake download page and build from source following the instructions below.

    The default prefix is /usr/local, make sure /usr/local/bin is in your $PATH.

    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 libungif (the actual name may vary between operating systems).


    If the problems persist, try the make-option --keep-going

    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 libxss headers installed. (Usually you got undefined references on xscreensaver objects if you haven't those headers)
    • which meinproc has to deliver /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 Xtst. On some systems, this is packaged separately from xext and called x11proto-xext-dev or libxtst-dev. 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 Starting a KDE4 Environment and Applications tutorial for how to start working on your new KDE4 installation.
