I met the following error…

ERROR: opencv-apps-0.1-r0 do_packagedata: The recipe opencv-apps is trying to install files into a shared area when those files already exist. Those files and their manifest location are:

    (matched in manifest-apalis_imx8-opencv.packagedata)
Please verify which recipe should provide the above files.

Can you guess why such an error keeps coming up ? I am very urgent…

Hi

The opencv recipe provides among others a package opencv-apps.
I assume that the recipe above is named opencv-apps_0.1.bb. I.e. it will create also a package opencv-apps.

In the do_packagedata tasks your recipe tries to copy files to somewhere the opencv recipe already provided its files. BOOM.

Maybe it is enough to rename your recipe to get further.
