Hi
I am trying to porting openwrt source code (v19.07.3) to a specific hardware.
I follow the instruction https://openwrt.org/docs/guide-developer/quickstart-build-images to try build the firmware. After executing make V=s, I meet the error below.

Do you have any idea about how to resolve the error ?
