本文介绍了在CentOS系统中正确安装G++的方法。当尝试使用命令'yum install g++'时，会发现找不到对应的软件包。这是因为CentOS中G++的实际包名为'gcc-c++'。正确的做法是运行'yum install gcc-c++'来完成安装。

在centos下安装g++，如果输入 yum install g++，那么将会提示：

[root@hugo hugo]# yum install g++
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
 * base: centos.ustc.edu.cn
 * extras: centos.ustc.edu.cn
 * updates: centos.ustc.edu.cn
Setting up Install Process
No package g++ available.
Error: Nothing to do

因为在centos下g++安装包名字叫做：gcc-c++

所以应该输入 yum install gcc-c++，即可。

[root@hugo hugo]# yum -y install gcc-c++
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
 * base: centos.ustc.edu.cn
