Building Plasma 5

Installation of Plasma5

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-1.8.15 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

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

       OPTS=""

       case $packagedir in
         kwayland-5.5.4 )
           OPTS="-DECM_MKSPECS_INSTALL_DIR=$KF5_PREFIX/share/mkspecs/modules"
           ;;

         libksysguard-5.5.4 )
           sed -i "1 i using namespace std;" ../signalplotter/ksignalplotter.cpp
           ;;
       esac

       cmake -DCMAKE_INSTALL_PREFIX=$KF5_PREFIX \
             -DCMAKE_BUILD_TYPE=Release         \
             -DLIB_INSTALL_DIR=lib              \
             -DBUILD_TESTING=OFF                \
             $OPTS                              \
             -Wno-dev ..  &&

        make
        as_root make install
    popd

    rm -rf $packagedir
    as_root /sbin/ldconfig

done < plasma-5.5.4.md5

exit

cd $KF5_PREFIX/share/plasma/plasmoids

for j in $(find -name \*.js); do
  as_root ln -sfv ../code/$(basename $j) $(dirname $j)/../ui/
done
