QtPositioning introduces an error

I’m attempting to use the QGeoCoordinate and QGeoRectangle C++ classes. After many linking failures, I finally found that I needed to add the positioning keyword to my .pro file. So I used…

QT += positioning.

After doing this, it would compile just fine but I would receive a segmentation fault error as soon as I tried to run it in debug mode.

I wasn’t sure where the SIGSEGV error was occurring, so I started placing break-points at strategic positions to try and determine at what spot in the code the problem was occurring. Unfortunately, even if I set a break-point at the first line of my main{}, it appeared as if program execution never got to the code I wrote.

Internet searches haven’t seemed to turn up any answers, so I’m hoping someone here may have come across this in the past or may know what my problem is.

I didn't include any code as the problem appears to be something else. I’m using Qt 5.7.0 with MinGW 32 bit from Qt Creator 4.1.0 on an HP Intel Xeon using Windows 7 Professional operating system with service pack 1 installed.

I'd appreciate any insight someone may have on this situation. Thanks in advance.

Do you have any global static objects, or class static objects? Those are initialised before the main is called, put a break point there and check.

Thanks for your reply Santosh.

The Ui namespace has global scope but I don't have any variables, classes or functions that are declared as static globaly.

I know this wasn't part of your suggestion, but since I'm using the QGraphicsObject class, I do have several pure virtual functions that are const with the declarations modified by the Q_DECL_OVERRIDE macro. So just on a whim, and because I've had issues with const values in the past, I tried breakpoints at those points but execution has never advanced even that far.

Not sure if it will help, but this is the debug dump...
