Required

CMake-4.2.3, Extra-CMake-Modules-6.23.0, GLib-2.86.4, and Qt-6.10.2

phonon-backend-vlc-0.12.0 needs to be installed afterwards for multimedia operations in KDE to work correctly.

Installation of Phonon

Install Phonon by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=/usr \
      -D CMAKE_BUILD_TYPE=Release  \
      -D PHONON_BUILD_QT5=OFF      \
      -W no-dev .. &&
make

Now, as the root user: 

make install

Command Explanations

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

-D PHONON_BUILD_QT5=OFF: This switch is needed to prevent building the Qt5 bindings, which fails if Qt5 is not installed.
