pure virtual method called terminate called without an active exception about libfreenect2pclgrabber

[nomi321]

i am using the following portion of your grabber to grab point cloud using kinect 2

boost::shared_ptrpcl::PointCloudpcl::PointXYZRGB cloud;
Processor freenectprocessor = OPENGL;
K2G k2g(freenectprocessor);
std::cout << "getting cloud" << std::endl;
cloud = k2g.getCloud();

and I want to use this cloud for further processing.

and this is the output i get

[Info] [Freenect2DeviceImpl] opening...

Hi,
Did you build the grabber with OPENGL support?
