## **安装交叉编译工具链**
* 解压交叉编译工具链
<pre>
$ tar xf gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12.tar.bz2 -C /opt/
</pre>
* 复制工具链配置文件
<pre>
$ cp environment-setup-cortexa9hf-neon-fsl-linux-gnueabi /opt/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/
</pre>
* 使工具链配置文件生效
<pre>
$ source /opt/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/environment-setup-cortexa9hf-neon-fsl-linux-gnueabi
