I am getting the below error when i try to run a simple opencv code


terminate called after throwing a[24778.491458] audit: type=1701 audit(1579182772.146:15): auid=4294967295 uid=0 gid=0 ses=4294967295 pid=4288 comm="motiondetection" exe="/home/root/motiondetection" sig=6 res=1

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'

I have added below package in local.conf

#opencv - for image processing
CORE_IMAGE_EXTRA_INSTALL += "opencv opencv-samples libopencv-core libopencv-imgproc"
CORE_IMAGE_EXTRA_INSTALL += "libopencv-core-dev libopencv-highgui-dev libopencv-imgproc-dev libopencv-objdetect-dev libopencv-ml-dev"

How to resolve it, I have attached the local.conf let me know if i had missed any package

Hello Santhosh,

Apparently you have to add libgtk2-0-dev to the CORE_IMAGE_INSTALL
