[SOLVED]Qt 5.1 available serial port list

[mikecurl91]

This the code I'm using:
@#include <QGuiApplication>
#include <QtQml>
#include <QtQuick/QQuickView>
#include <QtSerialPort/QSerialPortInfo>
#include <QList>

int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine(QUrl("qml/main.qml"));

   QList<QSerialPortInfo> list;

   QObject *topLevel = engine.rootObjects().value(0);
   QQuickWindow *window = qobject_cast<QQuickWindow *>(topLevel);
   if ( !window ) {
       qWarning("Error: Your root item has to be a Window.");
       return -1;
   }

   list = QSerialPortInfo::availablePorts();          <----------Error
   window->show();       
   return app.exec&#40;&#41;;

}@

but I've errors on the line indicated.
What is the problem? I'm trying to have simply the list of available ports on the pc!!
thanks
