安装uclinux开发工具链

3.拷贝工具链安装文件到/usr/local/armtools下
4.更改工具链到执行权限

5.执行安装

可能会出现如下错误
errors:
tail : cannot open `+43' for reading : No such file or directory

gzip:stdin: not in gizp format
tar: This does not look like a tar archive
tar: Error exit delayed from previous errors

解决方法：
1）打开脚本文件，sudo vi arm-elf-tools-20040427.sh，按下ESC，输入:set nu，显示行号，第39行修改为：tail -n +${SKIP} ${SCRIPT} | gunzip | tar xvf
2）在脚本文件arm-elf-tools-20040427.sh插入最后一行，按下ESC，然后输入G，输入o，保存退出
6.重新执行安装，安装完毕后，执行arm-elf-gcc -v，输出Reading specs from /usr/local/lib/gcc-lib/arm-elf/2.95.3/specs
gcc version 2.95.3 20010315 (release)(ColdFire patches - 20010318 from http://fiddes.net/coldfire/)(uClinux XIP and shared lib patches from http://www.snapgear.com/)
表明arm-elf-开发工具链安装成功。
