Chapter 15. Preparing KDE Frameworks Integration

Building KDE Frameworks 6.20.0 (KF6)

KDE Frameworks is a collection of libraries based on top of Qt6 and QML derived from the previous KDE libraries. They can be used independent of the KDE Display Environment (Plasma 6).

This package is known to build and work properly using an LFS 12.4 platform.

The instructions below build all of the KDE Frameworks packages in one step by using a bash script.

Package Information

KF6 Dependencies

Preparing KDE Frameworks

Now setup some scripts to auto start by either using nano or by following the instructions, as the root user: 

cat >> /etc/ld.so.conf << "EOF"
# Begin KF6 addition

/opt/kf6/lib

# End KF6 addition
EOF
cat > /etc/profile.d/kf6.sh << "EOF"
# Begin /etc/profile.d/kf6.sh

export KF6_PREFIX=/opt/kf6

pathappend $KF6_PREFIX/bin              PATH
pathappend $KF6_PREFIX/lib/pkgconfig    PKG_CONFIG_PATH

Downloading KDE Frameworks

The Order of the package download is the same as the build order, so easiest way to get the KDE Frameworks packages is to use a single wget script to fetch them all at once: 

cat > kde-kf6-download.sh << "EOF"
sources="/sources/"
major="6.20"
version="6.20.0"
baseurl="https://download.kde.org/stable/frameworks/${major}/"

    wget -P ${sources} -nc -c "${baseurl}${archive}"

Installation of KDE Frameworks

[Caution]

Caution

If installing in /opt and there is an existing /opt/kf6 either as a regular directory or a symbolic link, it should be reinitialized (as root): 

export KF6_PREFIX=/opt/kf6

mv -v /opt/kf6 /opt/kf6.old
install -v -dm755           $KF6_PREFIX/{etc,share}
ln -sfv /etc/dbus-1         $KF6_PREFIX/etc
ln -sfv /usr/share/dbus-1   $KF6_PREFIX/share
ln -sfv /usr/share/polkit-1 $KF6_PREFIX/share
install -v -dm755           $KF6_PREFIX/lib
ln -sfv /usr/lib/systemd    $KF6_PREFIX/lib

Sometimes the installation paths are hardcoded into installed files. If the installed directory is not /usr, rename the directory and create a symlink: 

mv -v /opt/kf6 /opt/kf6-6.20.0
ln -sfvn kf6-6.20.0 /opt/kf6

Command Explanations

-D CMAKE_PREFIX_PATH=$QT6DIR: This switch is used to allow cmake to find the proper Qt libraries.

-D CMAKE_BUILD_TYPE=Release: This switch is used to apply higher level of the compiler optimizations.

-D BUILD_TESTING=OFF: This switch is used to prevent building test programs and libraries that are of no use to an end user.

-D BUILD_PYTHON_BINDINGS=OFF: This switch is used to prevent building Python modules that require external optional dependencies.
