Errore: 'qtmobility' non è un nome del namespace

Question

Sto cercando di compilare: http://wiki.forum.nokia.com/index.php / fetching_a_map_tile_in_qt_using_google_maps

Sto usando Qt-Mobility 1.2 con QT 4.7 su OpenSUSUSE 11.2

Gli errori che sto ricevendo sono:

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

.

Il mio file .pro contiene:

TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .

HEADERS += MainWindow.h
SOURCES += main.cpp MainWindow.cpp

QT += network
CONFIG += mobility
MOBILITY = location

.

L'errore è riportato nel file di intestazione, che ho mostrato come segue:

#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;
}

.

Si prega di guidare.

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).
