Beyond Linux® From Scratch - Version 7.10

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-7.10 platform.

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

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=http://download.kde.org/stable/frameworks/5.25/
wget -r -nH --cut-dirs=3 -A '*.xz' -np $url

The options used here are:
  -r            recurse through child directories
  -nH           disable generation of host-prefixed directories
  --cut-dirs=3  remove three levels of directories when saving
  -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-5.25.0 and oxygen-icons5-5.25.0. The modemmanager-qt package may be built if its optional dependency has been installed.

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-1.8.17p1 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 inatalling in /opt and there is an existing /opt/kf5 either as a regular directory or a symbolic link, it should be removed (as root): 

rm -rf /opt/kf5

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

    tar -xf $file
    pushd $packagedir

      mkdir build
      cd    build

      cmake -DCMAKE_INSTALL_PREFIX=$KF5_PREFIX \
            -DCMAKE_PREFIX_PATH=$QT5DIR        \
            -DCMAKE_BUILD_TYPE=Release         \
            -DLIB_INSTALL_DIR=lib              \
            -DBUILD_TESTING=OFF                \
            -Wno-dev ..
      make
      as_root make install
  popd


  as_root rm -rf $packagedir
  as_root /sbin/ldconfig

done < frameworks-5.25.0.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/kf5-5.25.0
ln -sfvn kf5-5.25.0 /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.

-DLIB_INSTALL_DIR=lib: This switch is used to get libraries to install to $KF5_PREFIX/lib instead of $KF5_PREFIX/lib64 on a 64 bit system.

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

Contents

Installed Programs: There are 53 programs installed in /opt/kf5/bin.
Installed Libraries: There are too many kf5 libraries (79) to list separately.
Installed Directories: /opt/kf5 (symlink to /opt/kf5-5.25.0)
