Fixing build issues with phonon-backend-gstreamer-4.5.1

November 9th, 2011 No comments

I’ve decided to try and upgrade my LFS system to the latest version of KDE (4.7.3 as of the time of this writing) and correspondingly needed to upgrade phonon-backend-gstreamer. Unfortunately, following the previous version’s compilation instructions provided this nasty message:

[ 4%] Building CXX object gstreamer/CMakeFiles/phonon_gstreamer.dir/audiooutput.cpp.o

To fix this issue, make sure you have the latest GStreamer and phonon-backend-xine installed. Then I followed some of the advice from this KDE forum topic.

If, like me, you installed Qt into /opt/qt, create a symbolic link into the qt directory pointing to your system’s latest version of phonon. For later success with kde-runtime, create links to the libphonon libraries in /opt/qt-4.7.1/lib to your recently compiled /usr/lib64 versions (adjust paths to /usr/lib on 32-bit systems):

# mv /opt/qt-4.7.1/include/phonon /tmp
# ln -snf /usr/include/phonon /opt/qt-4.7.1/include/phonon
# cd /opt/qt-4.7.1/lib
# rm -rf libphonon*
# ln -snf /usr/lib64/libphonon.so libphonon.so
# ln -snf /usr/lib64/libphonon.so.4 libphonon.so.4
# ln -snf /usr/lib64/libphonon.so.4.5.1 libphonon.so.4.5.1
# ln -snf /usr/lib64/libphononexperimental.so libphononexperimental.so
# ln -snf /usr/lib64/libphononexperimental.so.4 libphononexperimental.so.4
# ln -snf /usr/lib64/libphononexperimental.so.4.5.1 libphononexperimental.so.4.5.1

Then rerun the compilation process for phonon-backend-gstreamer and voila, no more errors. (You’ll probably still have more issues to work out, but this gets past the phonon-backend-gstreamer blockade.)




I am currently running Ubuntu 14.04 LTS for a home server, with a mix of Windows, OS X and Linux clients for both work and personal use.
I prefer Ubuntu LTS releases without Unity - XFCE is much more my style of desktop interface.
