Help with the "Internal buffer is too small!" error

[Jun8]

Hello,

I have installed OpenNI and OpenCV (v2.4.0). Then, I compiled the kinect_maps example program using 

g++ `pkg-config opencv --cflags` kinect_maps.cpp -o kinect_maps `pkg-config opencv --libs`

and built it with no problems. When I run it though, I get the error:

Kinect opening ...

CvCapture_OpenNI::CvCapture_OpenNI : Failed to create production tree: Internal buffer is too small!

done.

Can not open a capture object.

This message is generated by cap_openni.cpp by the following:

    status = context.CreateProductionTree( deviceNode, productionNode );

    if( status != XN_STATUS_OK )

    {

        std::cerr << "CvCapture_OpenNI::CvCapture_OpenNI : Failed to create production tree: "

                  << std::string(xnGetStatusString(status)) << std::endl;

        return;

    }

I don't understand what causes the error. The openni_grabber example that comes with PCL works, so it's not the connection with the Kinect.

Thanks!

Maybe you don't have enough contineous memory available

to allocate this concrete production tree.
