Any suggestions? Hi, just tried 4.5 where the same happens. The errors don't seem to have been introduced by 4.6. apart from that the -Werror is set by arch/mips/ as follows bcm63xx/boards/Makefile:ccflags-y := -Werror fw/arc/Makefile:ccflags-y := -Werror jz4740/Makefile:ccflags-y := -Werror -Wall Kbuild:subdir-ccflags-y := -Werror oprofile/Makefile:ccflags-y := -Werror pmc-sierra/yosemite/Makefile:ccflags-y := -Werror powertv/asic/Makefile:ccflags-y := -Wall -Werror powertv/pci/Makefile:ccflags-y := -Wall -Werror There seems to be some need to clean this up. I guess for now you will need to drop the W=1 to build an image. I will talk to Ralf about this. Thanks, John

This defconfig is not in upstream AFAICS.

I believe mips should either fix all warnings or remove -Werror. Indeed, I have build-check scripts which work fine for many architectures with W=1, but not for mips, and from my POW introducing exceptions for mips is inconsistent.
