cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
cpp-4.4.7-4.el6.x86_64.rpm
gcc-4.4.7-4.el6.x86_64.rpm
gcc-c++-4.4.7-4.el6.x86_64.rpm
glibc-devel-2.12-1.132.el6.x86_64.rpm
glibc-headers-2.12-1.132.el6.x86_64.rpm
kernel-headers-2.6.32-431.el6.x86_64.rpm
libstdc++-devel-4.4.7-4.el6.x86_64.rpm
mpfr-2.4.1-6.el6.x86_64.rpm
ppl-0.10.2-11.el6.x86_64.rpm
安装流程如下所示：
rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm
rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
rpm -ivh mpfr-2.4.1-6.el6.x86_64.rpm
rpm -ivh cpp-4.4.7-4.el6.x86_64.rpm --force
rpm -ivh kernel-headers-2.6.32-431.el6.x86_64.rpm
rpm -ivh glibc-headers-2.12-1.132.el6.x86_64.rpm --force
rpm -ivh glibc-devel-2.12-1.132.el6.x86_64.rpm --force
rpm -ivh gcc-4.4.7-4.el6.x86_64.rpm --force
rpm -ivh libstdc++-devel-4.4.7-4.el6.x86_64.rpm
rpm -ivh gcc-c++-4.4.7-4.el6.x86_64.rpm
说明：--force参数是试用于冲突时候强制替换的，不一定都需要。
安装完成后验证：
