Help with Nethunter kernel building errors

I'm trying to port my Oneplus kernel, and it's also my first time compiling a kernel.
I've attached a screenshot.
It says it compiles successfully, but the errors seem valid enough to address.

I git cloned my sm6350 device then git cloned the Nethunter kernel builder inside that directory.
I used the empty local.config.example to let the default .config manage, not sure if thats correct.

What do you make of these errors?

images on this forum are poor quality, just copy/paste your terminal output (only need the relevent bits of course, not all).
