How to add OpenCV examples in imx-gpu-sdk recipe for i.MX8mq board?

[chandresh_tank]

Hello, 

I am trying to add OpenCV example applications present in the imx-gpu-sdk recipe source code but i am unable to build the OpenCV sample application codes?

Could you please show me how to modify the "../sources/meta-fsl-bsp-release/imx/meta-sdk/recipes-graphics/imx-gpu-sdk/imx-gpu-sdk_5.0.2.bb" recipe to include OpenCV examples in /opt/imx-gpu-sdk/ output directory? #imx8m-quad‌ #imx-gpu-sdk

Hello Chandresh,

The opencv is already prepared for install in i.MX8MQ, you don´t need to download the imx-gpu.sdk, the yocto image comes with opencv samples, if you want more demos you can go to opencv khronos page.

Hi, 

OpenCV is installed in the i.MX8MQ but in the imx-gpu-sdk, They have given some OpenCV examples. I have to integrade the OpenCL and OpenCV examples for my application purposes. That's why i was trying to compile the OpenCV tutorial examples given in the imx-gpu-sdk. 

I have compiled one of examples with FslBuild.py but now when i am trying to execute the compiled openCV tutorial, I get this run time error. 

root@imx8m-var-dart:/opt/imx-gpu-sdk/OpenCV/OpenCV101# ./OpenCV101

This is where i am stuck now.
