Chapter 30. KDE Frameworks 6

Building KDE Frameworks 6.9.0 (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).

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

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

Package Information

KF6 Dependencies

Required

extra-cmake-modules-6.9.0, breeze-icons-6.9.0, docbook-xml-4.5, docbook-xsl-nons-1.79.2, libcanberra-0.30, libgcrypt-1.11.0, libical-3.0.18, libxslt-1.1.42, lmdb-0.9.31, qca-2.3.9, qrencode-4.1.1, plasma-wayland-protocols-1.15.0, PyYAML-6.0.2, shared-mime-info-2.4, URI-5.31, and Wget-1.25.0 (required to download the packages)

Recommended

Aspell-0.60.8.1 (Dictionary backend for Sonnet), Avahi-0.8 (DNS-SD backend for KDNSSD), ModemManager-1.18.12 (needed to build ModemManager-Qt), NetworkManager-1.50.0 (needed to build NetworkManager-Qt), polkit-qt-0.200.0 (Authentication backend for KAuth), and Vulkan-Loader-1.3.301 (Add support for Vulkan graphics drivers)

Furthermore, the instructions below assume that the environment has been set up as described in Introduction to KF6.

Optional

Runtime dependency for FrameworkIntegration

Noto fonts

Additional recommended dependencies for kapidox

Doxygen-1.12.0 (Run time), doxypypy-0.8.8.7, doxyqml-0.5.3, and requests-2.32.3

Additional image formats support in KImageFormats

libavif-1.1.1, libjxl-0.11.1, libraw-0.21.3, libheif, OpenEXR

Optional dependencies for Solid

Optional dependency for KWallet

GPGME-1.24.1, built with C++ bindings (which is the default).

Optional dictionary backends for Sonnet

Hspell and Hunspell

Downloading KDE Frameworks

The easiest way to get the KDE Frameworks packages is to use a single wget to fetch them all at once: 

url=https://download.kde.org/stable/frameworks/6.9/
wget -r -nH -nd -A '*.xz' -np $url

The options used here are:
  -r            recurse through child directories
  -nH           disable generation of host-prefixed directories
  -nd           do not create a hierarchy of directories
  -A '*.xz'     just get the *.xz files
  -np           don't get parent directories

Setting Package Order

The order of building files is important due to internal dependencies. Create the list of files in the proper order as follows:

Installation of KDE Frameworks

[Note]

Note

When installing multiple packages in a script, the installation needs to be done as the root user. There are three general options that can be used to do this:

  1. Run the entire script as the root user (not recommended).

  2. Use the sudo command from the Sudo-1.9.16p2 package.

  3. Use su -c "command arguments" (quotes required) which will ask for the root password for every iteration of the loop.

One way to handle this situation is to create a short bash function that automatically selects the appropriate method. Once the command is set in the environment, it does not need to be set again. 

as_root()
{
  if   [ $EUID = 0 ];        then $*
  elif [ -x /usr/bin/sudo ]; then sudo $*
  else                            su -c \\"$*\\"
  fi
}

export -f as_root
[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): 

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

First, start a subshell that will exit on error: 

bash -e

Install all of the packages by running the following commands: 

while read -r line; do

    # Get the file name, ignoring comments and blank lines
    if $(echo $line | grep -E -q '^ *$|^#' ); then continue; fi
    file=$(echo $line | cut -d" " -f2)

    pkg=$(echo $file|sed 's|^.*/||')          # Remove directory
    packagedir=$(echo $pkg|sed 's|\.tar.*||') # Package directory

    name=$(echo $pkg|sed 's|-6.*$||') # Isolate package name

    tar -xf $file
    pushd $packagedir

      # kapidox is a python module
      case $name in
        kapidox)
          pip3 wheel -w dist --no-build-isolation --no-deps --no-cache-dir $PWD
          as_root pip3 install --no-index --find-links=dist --no-cache-dir --no-user kapidox
          popd
          rm -rf $packagedir
          continue
          ;;
      esac

      mkdir build
      cd    build

      cmake -D CMAKE_INSTALL_PREFIX=$KF6_PREFIX \
            -D CMAKE_INSTALL_LIBEXECDIR=libexec \
            -D CMAKE_PREFIX_PATH=$QT6DIR        \
            -D CMAKE_SKIP_INSTALL_RPATH=ON      \
            -D CMAKE_BUILD_TYPE=Release         \
            -D BUILD_TESTING=OFF                \
            -W no-dev ..
      make
      as_root make install
    popd

  as_root rm -rf $packagedir
  as_root /sbin/ldconfig

done < frameworks-6.9.0.md5

exit
[Note]

Note

Any modules that have been omitted can be installed later by using the same mkdir build; cd build; cmake; make; make install procedure as above.

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/kf6-6.9.0
ln -sfvn kf6-6.9.0 /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.
