gccLinux下安装GNU GCC编译器（linux安装gnu）
GNU GCC编译器是一个自由可源码的编程工具，可用于Linux系统。GCC是C/C++和Fortran等高级语言的编译器，为程序员提供了开发功能和优化技巧，帮助更好地编写代码。因此，安装GNU GCC编译器是加快应用程序开发的重要步骤。
在Linux下安装GNU GCC编译器的步骤很简单：
首先，打开终端并使用“sudo apt -get install gcc”命令安装GNU可执行文件。
然后，在命令行输入“gcc”，即可编译代码并显示版本信息：
[aaron@Xubuntu:~$ gcc
gcc (Ubuntu 7.4.0-1ubuntu1~16.04.4) 7.4.0

最后，使用“gcc -v”来查看安装完成后的状态：
[aaron@Xubuntu:~$ gcc -v
