# Building KDE Frameworks 6.26.0 (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

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

- Download (HTTP): https://download.kde.org/stable/frameworks/6.26

- Download MD5 sum: See Below

- Download size: 112 MB

- Estimated disk space required: 3.0 GB (205 MB installed)

- Estimated build time: 12 SBU (using parallelism=8)

### KF6 Dependencies

#### Required

Extra-CMake-Modules-6.26.0, breeze-icons-6.26.0, docbook-xml-4.5, docbook-xsl-nons-1.79.2, libcanberra-0.30, libdmtx-0.7.8, libgcrypt-1.12.2, libical-4.0.2, libsecret-0.21.7, libxslt-1.1.45, lmdb-0.9.35, qca-2.3.10, libqrencode-4.1.1, plasma-wayland-protocols-1.21.0, PyYAML-6.0.3, shared-mime-info-2.4, URI-5.34, and Wget-1.25.0 (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/6.26/
    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:

    cat > frameworks-6.26.0.md5 << "EOF"

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.

- This icon package is covered separately at breeze-icons-6.26.0. It is separate to allow users that need these icons but do not need the full set of KF6 packages (e.g. LXQt-Post-Install) to more easily install them. However they are a required dependency for several kf6 packages.

## Installation of KDE Frameworks

### 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-1.9.17p2 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

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-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                \
                -D BUILD_PYTHON_BINDINGS=OFF        \
                -W no-dev ..
          make
          as_root make install
        popd

      as_root rm -rf $packagedir
      as_root /sbin/ldconfig

    done < frameworks-6.26.0.md5

    exit

### 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/kf6-6.26.0
    ln -sfvn kf6-6.26.0 /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.
