arm-gcc

建立交叉编译环境：arm-linux-gcc-4.3.2 
1.将arm-linux-gcc-4.3.2.tgz复制到任意路径下； 
2.确保安装了标准C开发环境，sudo apt-get install build-essential libncurses5-dev; 
3.在终端进入arm-linux-gcc-4.3.2.tgz存放目录，再sudo tar -zxvf arm-linux-gcc-4.3.2.tgz -C /(注意大写C字母后留一个空格)，这样会自动解压到/usr/local/4.3.2目录下）； 
4.修改环境变量，使交叉编译环境生效。 
vim ~/.profile 
在这个文件最后添加上自己的环境变量：export PATH=$PATH:/usr/local/arm/4.3.2/bin 
然后在终端执行source ~/.profile ,即可立即生效。 
5. arm-linux-gcc -v 
Using built-in specs.
