安装gcc-c++时报错和原有gcc版本冲突

Centos 6.7 安装 gcc-c++时报下面的错误：

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
