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).



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

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

User Notes:

Downloading KDE Frameworks

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

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-5.101.0 and oxygen-icons5-5.101.0. 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.

Installation of KDE Frameworks



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-1.9.12p2 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.

  if   [ $EUID = 0 ];        then $*
  elif [ -x /usr/bin/sudo ]; then sudo $*
  else                            su -c \\"$*\\"

export -f as_root


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

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
          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
          rm -rf $packagedir

      mkdir build
      cd    build

            -DCMAKE_PREFIX_PATH=$QT5DIR        \
            -DCMAKE_BUILD_TYPE=Release         \
            -DBUILD_TESTING=OFF                \
            -Wno-dev ..
      as_root make install

  as_root rm -rf $packagedir
  as_root /sbin/ldconfig

done < frameworks-5.101.0.md5



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.

Useless systemd units have been installed in $KF5_PREFIX/lib. Remove them now (as root):

rm -rf $KF5_PREFIX/lib/systemd

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/kf5-5.101.0
ln -sfvn kf5-5.101.0 /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.
