Beyond Linux® From Scratch (systemd Edition) - Version 11.2

Chapter 30. KDE Frameworks 5

Building KDE Frameworks 5 (KF5)

KDE Frameworks 5 is a collection of libraries based on top of Qt5 and QML derived from the monolithic KDE 4 libraries. They can be used independent of the KDE Display Environment (Plasma 5).

This package is known to build and work properly using an LFS-11.2 platform.

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

Package Information

KF5 Dependencies

Required

Boost-1.80.0, extra-cmake-modules-5.97.0, docbook-xml-4.5, docbook-xsl-nons-1.79.2, giflib-5.2.1, libepoxy-1.5.10, libgcrypt-1.10.1, libical-3.0.14, libjpeg-turbo-2.1.4, libpng-1.6.37, libxslt-1.1.36, lmdb-0.9.29, qca-2.3.4, qrencode-4.1.1, phonon-4.11.1, plasma-wayland-protocols-1.7.0, shared-mime-info-2.2, URI-5.12, and Wget-1.21.3 (required to download the packages)

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/5.97/
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:

In the above list, notice that some files have been commented out with a hash (#) character. The extra-cmake-modules entry has been commented out because it was built earlier in the Introduction to KDE. The icon packages are covered separately at breeze-icons-5.97.0 and oxygen-icons5-5.97.0. The modemmanager-qt package may be built if its optional dependency has been installed. The kdewebkit may be built if the external package QtWebkit has been built. The kapidox package is a pure python package and cannot be built with the instructions below.

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-1.9.11p3 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/kf5 either as a regular directory or a symbolic link, it should be reinitialized (as root): 

mv -v /opt/kf5 /opt/kf5.old                         &&
install -v -dm755           $KF5_PREFIX/{etc,share} &&
ln -sfv /etc/dbus-1         $KF5_PREFIX/etc         &&
ln -sfv /usr/share/dbus-1   $KF5_PREFIX/share       &&
ln -sfv /usr/share/polkit-1 $KF5_PREFIX/share       &&
install -v -dm755           $KF5_PREFIX/lib         &&
ln -sfv /usr/lib/systemd    $KF5_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 $pkg|sed 's|-5.*$||') # Isolate package name

    tar -xf $file
    pushd $packagedir

      # kapidox is a python module
      case $name in
        kapidox)
          # First install some python module dependencies
          as_root pip3 install doxypypy doxyqml requests

          pip3 wheel -w dist --no-build-isolation --no-deps $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 -DCMAKE_INSTALL_PREFIX=$KF5_PREFIX \
            -DCMAKE_PREFIX_PATH=$QT5DIR        \
            -DCMAKE_BUILD_TYPE=Release         \
            -DBUILD_TESTING=OFF                \
            -Wno-dev ..
      make
      as_root make install
    popd

  as_root rm -rf $packagedir
  as_root /sbin/ldconfig

done < frameworks-5.97.0.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/kf5 /opt/kf5-5.97.0
ln -sfvn kf5-5.97.0 /opt/kf5

Command Explanations

-DCMAKE_PREFIX_PATH=$QT5DIR: This switch is used to allow cmake to find the proper Qt libraries.

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

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