imx8: custom yocto image throwing errors Nothing provides libopencv-* at do_rootfs

[vsuneja63]

Hi,

Thanks!

I am building a custom yocto imgae on kirkstone sources for imx8mq evk. Opencv build successfully but at the end of image while do_rootfs its throwing opencv libs not found errors. My local.conf contains

CORE_IMAGE_EXTRA_INSTALL += "opencv"

Not sure why these libs are not found, could see all the libs available in opencv(in build directory). Here are the logs:

Hello vsuneja63,

The AGL demo does not contain anything for Opencl, you will have to use a yocto from NXP or copy all the procedure for opencl.
