OPENCV Error in I.MX8MMini

[santhosh2]

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

Hi Santhosh

    I encounter this issue too.  Did you solve this already.

    I would appreciate it if you share it to me.

    Thanks.

As per NXP, OpenCV library doesnt support on IMX8MMini

ref the below link

Hi,

No errors for Yocto compilation Without  line below line in local.conf file

CORE_IMAGE_EXTRA_INSTALL += "libgtk2-0-dev "

Hi,

I have tried already adding to CORE_IMAGE and compiling, I am getting below error message.

Yocto Compilation Error

It Says no un build-able dependency

Let me know any other issue it might have
