Enter the kernel directory that created in TUT 2, and locate "Makefile".

In line 193 (approximately),   " ARCH ?=(SUBARCH)"

In line 194 (approximately),     "CROSS_COMPILE ?="

We change them to:

"ARCH =arm"

"CROSS_COMPILE =arm-linux-", and save.

Another way to do it is when we first time use "make menuconfig", we use:

#make  ARCH=arm CROSS_COMPILE=arm-linux- menuconfig
