arm-linux交叉编译环境搭建

wget http://kan.027cgb.com/587712/gcc-linaro-arm-linux-gnueabihf-4-9-2014-07_linux-tar.xz

xz -d gcc-linaro-arm-linux-gnueabihf-4-9-2014-07_linux-tar.xz
tar -xvf gcc-linaro-arm-linux-gnueabihf-4-9-2014-07_linux-tar -C /

vim    /etc/environment
#将文件编辑为：
PATH=":/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux/bin:/home/usr:/root/bin"
#然后执行
source  /etc/environment

yum install -y gcc gcc-c++ kernel-devel glibc.i686 glibc zlib.i686

arm-linux-gnueabihf-gcc -v
