下载下面rpm包：http://rpm.pbone.net/
依次安装：
rpm -Uvh kernel-headers-2.6.32-431.el6.x86_64.rpm
rpm -Uvh glibc-headers-2.12-1.132.el6.x86_64.rpm
rpm -Uvh glibc-devel-2.12-1.132.el6.x86_64.rpm
rpm -Uvh libgomp-4.4.7-4.el6.x86_64.rpm
rpm -Uvh ppl-0.10.2-11.el6.x86_64.rpm
rpm -Uvh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
rpm -Uvh mpfr-2.4.1-6.el6.x86_64.rpm
rpm -Uvh cpp-4.4.7-4.el6.x86_64.rpm
rpm -Uvh gcc-4.4.7-4.el6.x86_64.rpm
遇到error，在后面加上--nodeps --force
–nodeps 就是安装时不检查依赖关系
–force 就是强制安装（电脑上含旧版本的需要）
