Error: Package: gcc-c++-4.4.7-11.el6.i686 (c6-media)
Requires: gcc = 4.4.7-11.el6
Installed: gcc-4.4.7-16.el6.i686 (@base)
gcc = 4.4.4-15.el6
gcc = 4.4.7-16.el6
Available: gcc-4.4.7-11.el6.i686 (c6-media)
gcc = 4.4.7-11.el6
gcc = 4.4.4-15.el6
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
解决办法：将 gcc，cpp, libgomp 等等依赖先删除掉，然后重新直接安装 gcc-c++,让其自动安装它的正确版本的依赖的 gcc, cpp, libgomp:
[root@localhost ~]# yum install gcc-c++
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
