Phonon-4.12.0

Introduction to Phonon

Phonon is the multimedia API for KDE. It replaces the old aRts package. Phonon needs the VLC backend.

[Note]

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.

Package Information

Phonon Dependencies

Required

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

Required at runtime

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

Optional

PulseAudio-17.0

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.
