Hi I was trying to compile Weston-6.0 using yocto recipe. For this I backported some of the packages from master branch of poky to my own layer. During this process, there was one package xorgproto which was used in master branch of poky but in rocko branch this package is not there. However a similar package is there called xproto. Now there is a conflict between these two packages for installing the same headers. I appended xorgproto recipe and removed the installation of similar header files. But after this I am getting this error. However If I continue to compile these errors are ignored.

Is there any way by which I can correct these errors. Why is there no check in staging.bbclass if the file exists or not.

The error is shown below:
