1、以4.3.2版本的编译器为例
将arm-linux-gcc-4.3.2.tar.bz2放在/work目录下
解压缩：
sudo tar jxvf /work/arm-linux-gcc-4.3.2.tar.bz2 -C /
添加环境变量：
sudo vi /etc/environment
注释掉原有的环境变量
#PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/work/tools/gcc-3.4.5-glibc-2.3.6/bin"
增加新的环境变量并保存
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/arm/4.3.2/bin/"
使生效
source /etc/environment检查是否成功
book@book-desktop:/usr/local/arm/4.3.2/bin$ arm-linux-gcc -v
Using built-in specs.

2、更换3.4.5版本的编译器
将arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2放置在/work目录
解压缩
sudo tar jxvf /work/arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2 -C /
更改环境变量
sudo vi /etc/environment
注释掉原来的环境变量，增加新的环境变量
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/gcc-3.4.5-glibc-2.3.6/bin"
使生效
source /etc/environment
检查是否成功
book@book-desktop:/gcc-3.4.5-glibc-2.3.6/bin$ arm-linux-gcc -v
Reading specs from /gcc-3.4.5-glibc-2.3.6/bin/../lib/gcc/arm-linux/3.4.5/specs
