Try to build with phonon

[copiutzu]

Hi

I'm a new user of UBUNTU. I've installed the QT application and I tried to use phonon class libraries to create some sound application.

I'm trying to compile this code:

Phonon::MediaObject *mediaObject = new Phonon::MediaObject(this);
mediaObject->setCurrentSource(Phonon::MediaSource("/mymusic/barbiegirl.wav"));
Phonon::AudioOutput *audioOutput =
new Phonon::AudioOutput(Phonon::MusicCategory, this);
Phonon::Path path = Phonon::createPath(mediaObject, audioOutput);

but I get the following linker errors:

Can someone give me some ideas?

do you have libphonon-dev installed?
sudo apt-get install libphonon-dev

Thank you for the advice.
Unfortunately, I had it installed and still not working.

I had the same error when I wanted to use Creator with phonon. I've installed libphonon-dev and it worked. Thanks for the advice.
