部署交叉编译工具链
一. 安装arm-2009q3
1.1. 在虚拟机创建安装文件夹
1.1.1. 在/usr/local/下创建/usr/local/arm文件夹
1.1.2. 将arm-2009q3.tar.bz2放到相关文件夹
1.1.3. 解压压缩包
a. tar -jxvf arm-2009q3.tar.bz2
root@ubuntu:/usr/local/arm# ls arm-2009q3 arm-2009q3.tar.bz2 root@ubuntu:/usr/local/arm#
1.2. 测试交叉编译工具链
1.2.1. ./arm-none-linux-gnueabi-gcc -v
root@ubuntu:/usr/local/arm# cd arm-2009q3 root@ubuntu:/usr/local/arm/arm-2009q3# cd bin/ root@ubuntu:/usr/local/arm/arm-2009q3/bin# ./arm-none-linux-gnueabi-gcc -v Using built-in specs.

二. 添加交叉编译工具链到环境变量中
2.1. 环境变量的意义
2.1.1. 环境变量就是操作系统的全局变量。每一个环境变量对操作系统来说都是唯一的，名字和所代表的意义都是唯一的。linux系统可以有很多个环境变量。其中有一部分是linux系统自带的，还有一些是我们自己来扩充的。我们这里涉及到的一个环境变量是
PATH。PATH这个环境变量是系统自带的，它的含义就是系统在查找可执行程序时会搜索的路径范围。
2.2. 将工具链导出到环境变量
2.1.1. 导入环境变量
a. export PATH=/usr/local/arm/arm-2009q3/bin:$PATH
2.1.2. 查看导入后的环境变量
root@ubuntu:/usr/local/arm/arm-2009q3/bin# echo $PATH /usr/local/arm/arm-2009q3/bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games root@ubuntu:/usr/local/arm/arm-2009q3/bin#
2.3. 实现打开终端就执行导入
2.3.1. 在~/.bashrc中，添加export PATH=/usr/local/arm/arm-2009q3/bin:$PATH 即可
三. 工具链创建arm-linux-xxx符号链接
3.1. 使用脚本来创建
ln arm-none-linux-gnueabi-addr2line -s arm-linux-addr2line ln arm-none-linux-gnueabi-ar -s arm-linux-ar ln arm-none-linux-gnueabi-as -s arm-linux-as ln arm-none-linux-gnueabi-c++ -s arm-linux-c++ ln arm-none-linux-gnueabi-c++filt -s arm-linux-c++filt ln arm-none-linux-gnueabi-cpp -s arm-linux-cpp ln arm-none-linux-gnueabi-g++ -s arm-linux-g++ ln arm-none-linux-gnueabi-gcc -s arm-linux-gcc ln arm-none-linux-gnueabi-gcc-4.4.1 -s arm-linux-gcc-4.4.1 ln arm-none-linux-gnueabi-gcov -s arm-linux-gcov ln arm-none-linux-gnueabi-gdb -s arm-linux-gdb ln arm-none-linux-gnueabi-gdbtui -s arm-linux-gdbtui ln arm-none-linux-gnueabi-gprof -s arm-linux-gprof ln arm-none-linux-gnueabi-ld -s arm-linux-ld ln arm-none-linux-gnueabi-nm -s arm-linux-nm ln arm-none-linux-gnueabi-objcopy -s arm-linux-objcopy ln arm-none-linux-gnueabi-objdump -s arm-linux-objdump ln arm-none-linux-gnueabi-ranlib -s arm-linux-ranlib ln arm-none-linux-gnueabi-readelf -s arm-linux-readelf ln arm-none-linux-gnueabi-size -s arm-linux-size ln arm-none-linux-gnueabi-sprite -s arm-linux-sprite ln arm-none-linux-gnueabi-strings -s arm-linux-strings ln arm-none-linux-gnueabi-strip -s arm-linux-strip
