[Qt 4.4] Phonon Module

Hi :)
I try to use a phonon module but I have a problem in a compilation:eek::

Code:

---

C:\MinGW\bin\..\lib\gcc\mingw32\3.4.2\..\..\..\..\mingw32\bin\ld.exe: cannot find -lphonon

---

my code:

Code:

---

#include <phonon>

---

Code:

---

Phonon::MediaObject bip;
bip.setCurrentSource(Phonon::MediaSource("alerte.mp3"));
bip.play();

---

*.pro

Code:

---

QT += phonon

---

thank you!!

How did you install Qt? Did you compile it yourself? Did you examine configure output to verify that phonon support was enabled?
