error: ‘QtMobility’ is not a namespace-name - qt

Question

I am trying to compile: http://wiki.forum.nokia.com/index.php/Fetching_a_map_tile_in_Qt_using_Google_Maps
I am using Qt-Mobility 1.2 with Qt 4.7 on OpenSuse 11.2
The errors I am receiving are:
MainWindow.h:7: error: ‘QtMobility’ is not a namespace-name
MainWindow.h:7: error: expected namespace-name before ‘;’ token
MainWindow.h:10: error: expected class-name before ‘{’ token
In file included from /opt/qtsdk-2010.05/qt/include/QtCore/qcoreapplication.h:47,
from /opt/qtsdk-2010.05/qt/include/QtGui/qapplication.h:45,
from /opt/qtsdk-2010.05/qt/include/QtGui/QApplication:1,
from main.cpp:2:
/opt/qtsdk-2010.05/qt/include/QtCore/qeventloop.h:51: error: expected initializer before ‘QtCoreModule’
make: *** [main.o] Error 1
My .pro file contains:
TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .
HEADERS += MainWindow.h
SOURCES += main.cpp MainWindow.cpp
QT += network
CONFIG += mobility
MOBILITY = location
The error is reported in the header file, which I have shown as follows:
#include <QtNetwork/QNetworkAccessManager>
#include <QtNetwork/QNetworkReply>
#include <QPaintEvent>
#include <QPixmap>
using namespace QtMobility;
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow ();
void paintEvent(QPaintEvent* paintEvent);
public slots:
void handleNetworkData(QNetworkReply* reply);
private:
void fetchMap(const QSize& size, qreal latitude, qreal longitude);
private:
QNetworkAccessManager networkAccessManager;
QPixmap mapPixmap;
}
Please guide.

You'll need to include at least one QtMobility header to be able to use that namespace.
Also that using namespace declaration is not the recommended way anymore. Use:
QTM_USE_NAMESPACE
instead (see QtMobility QuickStart).
