From: Tiago Maluta on 17 Jun 2010 09:00 Linux has an recent option to define CROSS_COMPILE in menuconfig. Typically, one of the options when building for another target is ('arm' is just an example): # make ARCH=arm CROSS_COMPILE=arm-cc O=../build If I omit CROSS_COMPILE and use the new way in .config: CONFIG_CROSS_COMPILE="arm-cc" I got: cc1: error: unrecognized command line option "-mlittle-endian" cc1: error: unrecognized command line option "-mabi=aapcs-linux" cc1: error: unrecognized command line option "-mno-thumb-interwork" /usr/src/linux/kernel/bounds.c:1: error: bad value (armv5t) for -march= switch /usr/src/linux/kernel/bounds.c:1: error: bad value (armv5t) for -mtune= switch make[2]: *** [kernel/bounds.s] Error 1 make[1]: *** [prepare0] Error 2 make: *** [sub-make] Error 2 Verbose output clearly says that I'm using the host compiler instead cross compiler.
