Project File

Qt Mobility should be included at the project file. Additionally if the application is targeting Symbian devices Location should be added as a capability [developer.qt.nokia.com].

Troubleshooting

• ‘QGeoPositionInfo’ has not been declared

All required header files must be included and the Qt Mobility namespace should be specified.

• AllPositioningMethods does not work as expected

This is a known critical bug that affects Qt Mobility 1.1.2 [bugreports.qt.io] Please check the provided link for details.
