RedHat linux 5.0 的问题
我的VM上安装了RedHat Linux 5.0 在使用gcc时出现了以下问题：
[[kai@localhost ~]$ gcc -o process process.c
bash: gcc: command not found
[kai@localhost ~]$ yum install
Loading "installonlyn" plugin
Loading "rhnplugin" plugin
Loading "security" plugin
This system is not registered with RHN.
RHN support will be disabled.
You need to be root to perform this command.
[kai@localhost ~]$
我是一个初学者，请各位高手帮忙，谢谢了！还有，是不是需要安装gcc ， 我也不知道怎样下载来安装，再次谢过了！
