KDE4/KDE Pre-Installation Configuration

To prevent KDE4 from killing KDE3 we only talk about installing into /opt. This will be changed once KDE4 has been tested and more accepted. We use a hard link to /opt/kde4 to prevent /opt/KDE from being removed and causeing KDE3 to fail.

If you're using the Bash Startup Files then run the commands below. Otherwise make sure that the values you want are properly set.

Installing KDE into /opt

Create the /opt/kde4 directory:

install -dv -m755 /opt/kde4

Non-Multilib

Create an addition to the Bash Startup Files:

cat > /etc/profile.d/30-kde4.sh << "EOF"
# Begin /etc/profile.d/30-kde4.sh

export KDEDIR=/opt/kde4
export KDEDIRS=$KDEDIR
export QTDIR=/opt/qt4
export KDETMP=/tmp/$USER-kde4
export QT_PLUGINS_DIR=$KDEDIR/lib/kde4/plugins:$QTDIR:$QT_PLUGINS_DIR
export PATH="${PATH}:${KDE_PREFIX}/bin"
export PKG_CONFIG_PATH="${PKG_CONFIG_PATH}${PKG_CONFIG_PATH+:}${KDE_PREFIX}/lib/pkgconfig"

# End /etc/profile.d/30-kde.sh
EOF
source /etc/profile

Add a new entry to /etc/ld.so.conf for the libraries that KDE is going to install:

cat >> /etc/ld.so.conf << "EOF"
# Begin KDE4 addition to /etc/ld.so.conf

/opt/kde4/lib

# End KDE addition
EOF

Multilib

Create an addition to the Bash Startup Files:

cat > /etc/profile.d/30-kde4.sh << "EOF"
# Begin /etc/profile.d/30-kde4.sh

export KDE_PREFIX=/opt/kde4
export KDEDIRS=$KDEDIR
export QTDIR=/opt/qt4
export KDETMP=/tmp/$USER-kde4
export PATH="${PATH}:${KDE_PREFIX}/bin"

export QT_PLUGINS_DIR32=$KDEDIR/lib/kde4/plugins:$QTDIR/lib:$QT_PLUGINS_DIR
export QT_PLUGINS_DIR64=$KDEDIR/lib64/kde4/plugins:$QTDIR/lib64:$QT_PLUGINS_DIR
export PKG_CONFIG_PATH32="${PKG_CONFIG_PATH32}${PKG_CONFIG_PATH32+:}${KDE_PREFIX}/lib/pkgconfig"
export PKG_CONFIG_PATH64="${PKG_CONFIG_PATH64}${PKG_CONFIG_PATH64+:}${KDE_PREFIX}/lib64/pkgconfig" 

# End /etc/profile.d/30-kde.sh
EOF
source /etc/profile

Add a new entry to /etc/ld.so.conf for the libraries that KDE is going to install:

cat >> /etc/ld.so.conf << "EOF"
# Begin KDE4 addition to /etc/ld.so.conf

/opt/kde4/lib
/opt/kde4/lib64

# End KDE addition
EOF

Now we set and unset some VARIBLES that will effect KDE4 and KD3. you might need to modify them depended on you system.

unset $PATH
export PATH=$KDEDIR/bin:/opt/qt4/bin:/bin:/usr/bin:/usr/local/bin
