Hi Randy, And to explain more specifically what's happening:

(The first warning was during the .config parsing pass, the second warning was during the binary build pass.) > config-r8737:# CONFIG_CC_STACKPROTECTOR_STRONG is not set > [...] > build-r8737.out:/local/lnx/MM/mmotm-2014-0702-1507/Makefile:662: Cannot use > CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by > compiler This is the same issue: the prior .config was still there with STRONG set, but after finishing the new .config parsing pass, everything is happy for the binary build pass. And, I assume, the r8737 didn't fail to build. The trouble seems to be how kbuild handle .config changes, but I was never able to sort it out. -Kees -- Kees Cook @outflux.net -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
