[Qt-creator] help - "Phonon Music player example problem in ubuntu 8.10"

[vinay golthaje]

When I compiled sources from a example at
http://doc.trolltech.com/4.4/phonon-musicplayer.html , It could not play any
file.
It says:

$./musicplayer
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
Phonon::createPath: Cannot connect Phonon::MediaObject(no objectName) to
Phonon::AudioOutput(no objectName).
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded

but I've installed phonon-backend-gstreamer.

After searching in google, I made a workround:

sudo ln -s /usr/lib/kde4/plugins/phonon_backend
/usr/lib/qt4/plugins/phonon_backend

but still getting the same error as above...

Please help me with this error........
