Hmm, this won't make sense for ARM. We have things like #warning and deprecated functions in machine specific headers, and adding -Werror to the whole of arch/arm/ will result in these causing builds to fail. Adding it just for boot,common,kernel,lib,mm,nwfpe,oprofile,vfp (iow everything except the mach-* and plat-* directories) would make sense though. > The feature is added because the x86 guys are planning > to (conditionally) cover all of arch/x86/ with -Werrror > and adding this statement in each single Makefile > was *the wrong way* to do so. I think that's the way we're going to _have_ to do it on ARM. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
