gcc4.1.2通过rpm包升级gcc4.4.7

由于环境不能连外网，不能通过yum安装，所以我采用rpm包安装的方式。

所用系统为CentOS 6.3,64位。

所需安装包

gcc-4.47-17.e16.x86_64.rpm

cloog-ppl-0.15.7-1.2.el6.x86_64.rpm

mpfr-2.4.1-6.e16.x86_64.rpm

ppl-0.10.2-11.el6.x86_64.rpm

cpp-4.4.7-17.el6.x86_64.rpm

libgcc-4.4.7-17.el6.x86_64.rpm

libgomp-4.4.7-17.el6.x86_64.rpm

安装cloog-ppl

cloog-ppl下载地址:https://centos.pkgs.org/6/centos-x86_64/cloog-ppl-0.15.7-1.2.el6.x86_64.rpm.html

安装过程中报错：

[root@localhost gcc]# rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm

warning: cloog-ppl-0.15.7-1.2.el6.x86_64.rpm: Header V3 RSA/SHA256Signature, key ID c105b9de: NOKEY

error: Failed dependencies:

        libppl.so.7()(64bit)is needed by cloog-ppl-0.15.7-1.2.el6.x86_64

        libppl_c.so.2()(64bit)is needed by cloog-ppl-0.15.7-1.2.el6.x86_64

解决依赖包，需要安装mpfr和ppl

mpfr : https://centos.pkgs.org/6/centos-x86_64/mpfr-2.4.1-6.el6.x86_64.rpm.html

ppl:http://vault.centos.org/6.3/os/x86_64/Packages/

安装ppl时报错：

[root@localhost gcc]# rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm
