• 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
    Setting up Install Process
    Loading mirror speeds from cached hostfile
