3.3.1 Setenv.sh

The script "setenv.sh" is mainly used to configure the developing environment

quickly. It will configure the important folder paths for system, and you can also add/

modify the setenv.sh by yourself if you have added/changed the folder paths.

The default code of setenv.sh is shown as following:

#!/bin/bash

export SRCROOT=${PWD}/..

export CC_PATH=${SRCROOT}/cross_compiler/arm-fsl-linux-gnueabi

export CROSS_COMPILE=$CC_PATH/bin/arm-none-linux-gnueabi-

export ARCH=arm

export KROOT=${SRCROOT}/source/linux-2.6.35.3

export ROOTFS=${SRCROOT}/rootfs

export LOG=${SRCROOT}/Build.log

rm -rf ${LOG}
