首先到http://vault.centos.org/6.3/os/x86_64/Packages/下载用到的rpm包，包括：ppl-0.10.2-11.el6.x86_64.rpm、cloog-ppl-0.15.7-1.2.el6.x86_64.rpm、mpfr-2.4.1-6.el6.x86_64.rpm 、cpp-4.4.6-4.el6.x86_64.rpm 、kernel-headers-2.6.32-279.el6.x86_64.rpm、glibc-headers-2.12-1.80.el6.x86_64.rpm 、glibc-devel-2.12-1.80.el6.x86_64.rpm 、libstdc++-devel-4.4.6-4.el6.x86_64.rpm 、gcc-4.4.6-4.el6.x86_64.rpm 、gcc-c++-4.4.6-4.el6.x86_64.rpm
安装流程如下所示：
二，安装
将下载好的包传到Linux中后，使用命令进行安装
- 1
- 1
运行这条命令后，会根据依赖按照顺序安装rpm
或者可以一步步安装：
