KF5 can be installed in /usr or /opt/kf5. The BLFS editors recommend the latter in the BLFS environment.
One option is to install KDE Frameworks
5 into the /usr
hierarchy.
This creates a simpler setup but makes it more difficult to try
multiple versions of KDE
Frameworks.
export KF5_PREFIX=/usr
It is a good idea to add the following variables to your system or personal profiles:
cat >> /etc/profile.d/qt5.sh << "EOF"# Begin kf5 extension for /etc/profile.d/qt5.sh pathappend /usr/lib/qt5/plugins QT_PLUGIN_PATH pathappend $QT5DIR/lib/plugins QT_PLUGIN_PATH pathappend /usr/lib/qt5/qml QML2_IMPORT_PATH pathappend $QT5DIR/lib/qml QML2_IMPORT_PATH # End extension for /etc/profile.d/qt5.sh
EOF cat > /etc/profile.d/kf5.sh << "EOF"# Begin /etc/profile.d/kf5.sh export KF5_PREFIX=/usr # End /etc/profile.d/kf5.sh
EOF
If qt5 was installed in /usr, the $QT5DIR/lib/ portions of the above paths may need to be changed to $QT5DIR/lib/qt5/.
If KDE4 is installed in
/usr
, some packages from this
chapter might overwrite some programs installed by KDE4 packages.
A method of building multiple versions installs KDE Frameworks 5 in the /opt
hierarchy:
export KF5_PREFIX=/opt/kf5
If you are not installing KDE Frameworks
5 in /usr
, you will need to
make some additional configuration changes. Best practice is to add
those to your system or personal profile:
cat > /etc/profile.d/kf5.sh << "EOF"# Begin /etc/profile.d/kf5.sh export KF5_PREFIX=/opt/kf5 pathappend $KF5_PREFIX/bin PATH pathappend $KF5_PREFIX/lib/pkgconfig PKG_CONFIG_PATH pathappend /etc/xdg XDG_CONFIG_DIRS pathappend $KF5_PREFIX/etc/xdg XDG_CONFIG_DIRS pathappend /usr/share XDG_DATA_DIRS pathappend $KF5_PREFIX/share XDG_DATA_DIRS pathappend $KF5_PREFIX/lib/plugins QT_PLUGIN_PATH pathappend $KF5_PREFIX/lib/qml QML2_IMPORT_PATH pathappend $KF5_PREFIX/lib/python2.7/site-packages PYTHONPATH pathappend $KF5_PREFIX/share/man MANPATH # End /etc/profile.d/kf5.sh
EOF cat >> /etc/profile.d/qt5.sh << "EOF"# Begin Qt5 changes for KF5 pathappend $QT5DIR/plugins QT_PLUGIN_PATH pathappend $QT5DIR/qml QML2_IMPORT_PATH # End Qt5 changes for KF5
EOF
Expand your /etc/ld.so.conf
file:
cat >> /etc/ld.so.conf << "EOF"
# Begin KF5 addition
/opt/kf5/lib
# End KF5 addition
EOF
Several KDE Frameworks 5 packages
install files into D-Bus
directories. When installing KDE
Frameworks 5 in a location other than /usr
, D-Bus
needs to be able to find these files. The easiest way to achieve
this is to create the following symlinks (as the root
user):
install -v -dm755 $KF5_PREFIX/{etc,share} && ln -sfv /etc/dbus-1 $KF5_PREFIX/etc && ln -sfv /usr/share/dbus-1 $KF5_PREFIX/share
Some packages may also install icons from the "hicolor" icon set.
Since that icon set is used by many packages, it is a good idea to
create a symlink to the one in /usr/share
to avoid having multiple installations
of hicolor-icon-theme-0.15. Run the
following commands as the root
user:
install -v -dm755 $KF5_PREFIX/share/icons && ln -sfv /usr/share/icons/hicolor $KF5_PREFIX/share/icons
Sometimes, the installation paths are hardcoded into installed
files. This is the reason why /opt/kf5
is used as installation prefix instead
of /opt/kf5-5.37.0
. After
installing KDE Frameworks, you
may rename the directory and create a symlink:
mv /opt/kf5{,-5.37.0} ln -sfv kf5-5.37.0 /opt/kf5
Later on, you may want to install other versions of KDE Frameworks 5. To do that, just remove
the symlink and use /opt/kf5
as the
prefix again. Which version of KDE
Frameworks 5 you use depends only on where the symlink
points. No other reconfiguration will be needed.
