QtMobility's class not recognized !

[sami.mahjoub]

I have a really project to test some fonction on Mobility API
But I have a really strange error !

This is my code:

#include <QMainWindow>
#include <qmobilityglobal.h>
#include <QGeoPositionInfo>
#include <QGeoPositionInfoSource>
#include <QObject>

class MyClass : public QObject
{

Q_OBJECT
public:
MyClass(QObject *parent = 0)
: QObject(parent)
{
QGeoPositionInfoSource *source = QGeoPositionInfoSource::createDefaultSource(this);
if (source) {
connect(source, SIGNAL(positionUpdated(QGeoPositionInfo)),
this, SLOT(positionUpdated(QGeoPositionInfo)));
source->startUpdates();
}
}

public slots:
void positionUpdated(QGeoPositionInfo & info)
{
qDebug() << "Position updated:" << info;
}
};

this is the .pro file

QT += core gui
QT += core

TARGET = testgraphique
TEMPLATE = app


SOURCES += main.cpp\
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui

CONFIG += mobility
MOBILITY = location

symbian {
TARGET.UID3 = 0xe62b586b
# TARGET.CAPABILITY +=
TARGET.EPOCSTACKSIZE = 0x14000
TARGET.EPOCHEAPSIZE = 0x020000 0x800000
}

unix:!symbian {
maemo5 {
target.path = /opt/usr/bin
} else {
target.path = /usr/local/bin
}
INSTALLS += target
}

And this are errors:

/home/ubis/QtSDK/works/testgraphique-build-maemo/../testgraphique/mainwindow.h:29: erreur : 'QGeoPositionInfo' has not been declared
/home/ubis/QtSDK/works/testgraphique-build-maemo/../testgraphique/mainwindow.h:20: erreur : 'QGeoPositionInfoSource' was not declared in this scope

Any help will be appreciated

For which platform are you build this project and what is being selected in the "Build Configuration" under project icon

[sami.mahjoub]

it's for Nokia N900 and for the build configuration it's "Qt for Fremantle PR1.3 Devices (Qt SDK)"

There are over 9000 similar questions on DiBo. It looks like Maemo target is incomplete (probably as result of running SDK updater).

Are you running Qt SDK 1.1 Beta or Qt SDK 1.1 RC? What OS are you using as the build host?

I just tried out you code on Qt SDK 1.1 Beta on x86 Linux and had no issues. Here is my .pro file:


# Add files and directories to ship with the application
# by adapting the examples below.
# file1.source = myfile
# dir1.source = mydir
DEPLOYMENTFOLDERS = # file1 dir1

symbian:TARGET.UID3 = 0xE79C2677

# Allow network access on Symbian
symbian:TARGET.CAPABILITY += NetworkServices

# If your application uses the Qt Mobility libraries, uncomment
# the following lines and add the respective components to the
# MOBILITY variable.
# CONFIG += mobility
# MOBILITY +=

SOURCES += main.cpp mainwindow.cpp \
myobject.cpp
HEADERS += mainwindow.h \
myobject.h
FORMS += mainwindow.ui

CONFIG += mobility
MOBILITY += location

# Please do not modify the following two lines. Required for deployment.
include(deployment.pri)
qtcAddDeployment()

Isn't he just missing the obscure "using" statement?

Thanks every body !
it was "QTM_USE_NAMESPACE" missing on my header file !
