QGeoPositionInfoSource::createDefaultSource(this) Does not fire events ...

  • Hi,

    I would like to use the "gpsd" damon on a ubuntu 17.04 system. The samples "weatherinfo" and "Satellitinfo" are working with the plugin "libqtposition_gpsd" without any problem.

    But when I use my own program, then it does not fire any event in the defined functions. I placed a break point in the slots, which was never reached.


    private slots:
            void    positionUpdated(QGeoPositionInfo);
            void    positionError(QGeoPositionInfoSource::Error);
            void    updateTimeout(void);

    Program code

    void		SensorThread::positionUpdated(QGeoPositionInfo info)
    void    SensorThread::positionError(QGeoPositionInfoSource::Error   gpserror)
        qDebug() << gpserror;
    void    SensorThread::updateTimeout(void)
        qDebug() << "Time out";
    void SensorThread::run(void)
        m_ProgramInfo->writelog(tr("carclient"),tr("SensorThread"),tr("Info"),tr("Thread startup"));
        qt_Position = QGeoPositionInfoSource::createDefaultSource(this);
        if (qt_Position)
            connect(qt_Position, SIGNAL(positionUpdated(QGeoPositionInfo)),this, SLOT(positionUpdated(QGeoPositionInfo)));
            connect(qt_Position, SIGNAL(error(QGeoPositionInfoSource::Error)),this, SLOT(positionError(QGeoPositionInfoSource::Error)));
            connect(qt_Position, SIGNAL(updateTimeout()),this, SLOT(updateTimeout()));
            m_ProgramInfo->writelog(tr("carclient"),tr("SensorThread"),tr("Error"),tr("Could not create qt_Position Object"));

    Here is the output of the program during debug session

    Debugging starts
    &"warning: GDB: Failed to set controlling terminal: Unpassender IOCTL (I/O-Control) f\303\274r das Ger\303\244t\n"
    Connected to gpsd
    Created slave QBuffer(0x7fffd4006100)
    Unpausing slave QBuffer(0x7fffd4006100)
    Starting gpsd
    Debugging has finished

    How can I get closed to the problem ?

    Best regards

  • Hello all,

    I just recode the use of the application instead of C++ to Quick Qt and
    now I get the events.
