Answer 1

缺少依赖的包，Linux下的软件有一些是需要先安装其它包才能安装使用的，它们之间这种联系成为依赖关系。如果可以联网的话，建议你使用yum安装，以root身份执行yum install gcc即可，yum会帮你安装其它依赖包的了。

Answer 2

依赖关系没解决，你应该yum install gcc gdb gcc-c++ -y,自动解决依赖关系

Answer 3

你真以为 GCC 就是一个软件包啊？
另外你真以为只装一个 GCC 就能开发了啊？

很多系统的 GCC 被拆成了无数个小软件包。而且 GCC 并不是“绿色”的，还需要安装很多杂七杂八的支持环境。而且 GCC 本身只是编译器，连接器、过程控制、头文件、基本函数库什么的都不含。
