    Build instructions

    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
    

    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 $@ && 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
    

    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:

    ssh -X kde-devel@localhost
    kwrite
