I'm trying to initialize OpenNI sensors using OpenCV in order to get depth map from depth sensor of my kinect.

The code I used to get one depth image:

and The output I get:

LNK2019: unresolved external symbol "int __cdelc cv::waitKey(int)" (?waitKey@cv@@YAHH@Z) reference in function _main

In the .pro file I have:

QT += widgets
WITH_OPENNI = ON

you've got an unresolved external symbol, are you sure you have all your includes? – Boumbles Apr 16 '13 at 13:39

This is not an include but a linking error. You are missing some library (don't know which though) – Elmar Peise Apr 16 '13 at 13:42

Its highgui library that you are missing.. – UltraInstinct Apr 16 '13 at 14:17
solved! I edited CMake.txt and now OpenCV can be recognized. Thank you, it was, as you said, a missing library – ali Apr 16 '13 at 14:20
