I am getting error Cannot open output file a.out: Permission denied when i tried to run the sample program which are
present in opencv-2.4.11 directory. the path of the directory is /home/pi/opencv-2.4.11/samples/.. the properties of the cpp file are -rw-r--r-- 1 root root starter_video.cpp.
i even tried to change the permission for directory /home/pi/opencv-2.4.11/samples/.. it didn't work. it throw "Changing permissions of 'samples' : Operation not permitted".
Please advice
