Playing audio in QML

? Offline

I am trying to create a JukeBox program. I have started by trying to play audio in QML. I am using phonon module to create a class that is able to play an audio file and then I have registered this in QML. I am obviously making a fundamental error as I get following issues when trying to run it:

error: symbol(s) not found for architecture x86_64
error: collect2: ld returned 1 exit status

here is my code, there is not much to it:

in JukeBox.pro I added

@QT += core gui phonon declarative@

qmlaudio.h

@#ifndef QMLAUDIO_H
#define QMLAUDIO_H

#include <phonon>
#include <QDeclarativeItem>
#include <QUrl>

class QmlAudio : public QDeclarativeItem
{
Q_OBJECT
public:
QmlAudio(QDeclarativeItem *parent = 0);

public slots:
void setSong(const QUrl & songUrl);
void play();

private:

Phonon::MediaObject *audioObject;

};

#endif // QMLAUDIO_H
@

qmlaudio.cpp

@#include "qmlaudio.h"
#include <QObject>
#include <phonon>

QmlAudio::QmlAudio(QDeclarativeItem *parent) : QDeclarativeItem(parent)
{

audioObject = Phonon::createPlayer(Phonon::MusicCategory,
                                   Phonon::MediaSource("/Users/jankokajtez/My Docs/Qt Projects/JukeBox/qml/JukeBox/song.mp3"));

}

void QmlAudio::setSong(const QUrl & songUrl)
{
audioObject->setCurrentSource(Phonon::MediaSource(songUrl));
}

void QmlAudio::play()
{
audioObject->play();
}

main.cpp

@#include <QtGui/QApplication>

Q_DECL_EXPORT int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QDeclarativeView viewer;
qmlRegisterType<QmlAudio>("qmlAudio", 1, 0, "QmlAudio");
viewer.setSource(QUrl("/Users/jankokajtez/My Docs/Qt Projects/JukeBox/qml/JukeBox/main.qml"));
viewer.show();

return app.exec();

People here have a similar issue(though not with playing audio), but yes error messages are same:

Are there any more compiler generated statements btw, if yes try pasting it here.
