How To Use Phonon?

[ardisaz]

Hai Guys, im new with Qt
I had a problem
I want to make a music player simulator (like piano or drum)
recently, i'm using QSound, but i have problem because i cant play multiple sound

I want to try using Phonon. But i found a problem...
My Code is

void uxbonang::bon_play(){
Phonon::MediaObject *music =
Phonon::CreatePlayer (Phonon::MusicCategory,
Phonon::MediaSource("C://Qt/Pro/sound.wav"));
}

i already included
phonon/MediaObject
phonon/MeidaSource

But i got an error message like this

"......undefined reference to '_imp__ZN6Phonon11MediaSourceC1ERK7QString'
...undefined reference to '_imp__ZN6Phonon12CreatePlayerENS_8CategoryERKNS_1 1MediaSourceE'
...undefined reference to '_imp_ZN6Phonon11MediaSourceD1Ev'
...undifned reference to '_imp_ZN6Phonon11MediaObjectPlayEv'
"

What should i Do?
thx

Add

QT += phonon

QT += phonon

Then clean the project and rebuild.
