I followed the instructions and even though I compiled successfully two examples from the CPP examples folder of OpenCV (https://github.com/Itseez/opencv/tree/2.4.9.1/samples/cpp), I had the following problems when running them:

Example 1: Image Processing:

$g++ edge.cpp -lopencv_core -lopencv_imgproc -lopencv_highgui -o edge
$./edge

This sample demonstrates Canny edge detection
Call:
/.edge [image_name -- Default is fruits.jpg]

OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /hdd/buildbot/slaves/slave_jetson_tk1/52-O4T-L4T/opencv/modules/highgui/src/window.cpp, line 483

Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvNamedWindow

Example 2: Video processing

$g++ bgfg_segm.cpp -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_video -o bgfg
$./bgfg -f 768x576.avi

Do background segmentation, especially demonstrating the use of cvUpdateBGStatModel().
Learns the background at the start and then segments.
Learning is togged by the space key. Will read from file or camera
Usage:
./bgfg_segm [--camera]=<use camera, if this key is present>, [--file_name]=

-c, --camera=[true] use camera or not
-fn, --file_name=[tree.avi] movie file
can not open camera or video file

Any ideas?

Thanks

Hi Jetsonhacks,

I also have the issue, can you get me some advises ?
My release is R21.3.

Thanks
