如何在CentOS 7或Red Hat Enterprise Linux版本7服务器上安装gnu gcc编译器和相关工具，例如autoconf，automake，flex，c ++编译器和bison？
如何在CentOS或RHEL 7上安装GCC(C和C ++编译器)和开发工具？
您可以在CentOS Enterprise Linux或Red Hat Enterprise Linux版本7上使用以下软件包设置基本的开发环境：

CentOS/RHEL 7：安装GCC软件包列表

• autoconf
• automake
• binutils
• bison
• flex
• gcc (c compiler)
• gcc-c++ (c++ compiler)
• gettext
• libtool
• make
• patch
• pkgconfig
• redhat-rpm-config
• rpm-build
• rpm-sign

安装GCC C和C ++

打开终端应用程序，然后键入以下命令。

在CentOS/RHEL 7上列出组的命令

键入以下yum命令：

# yum group list

输出示例：
CentOS/RHEL 7：列表软件包组命令

另外一个选项：

# yum group list ids

输出示例：

Loaded plugins: fastestmirror
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
Loading mirror speeds from cached hostfile

在CentOS/RHEL 7服务器上安装GCC和开发工具的命令

以超级用户身份键入以下yum命令：

# yum group install "Development Tools"

或者

$ sudo yum group install "Development Tools"

如果以上命令失败，请尝试：

# yum groupinstall "Development Tools"

输出示例：gif动画01：在CentOS和RHEL 7上安装C&C ++和相关软件包

关于在CentOS/RHEL 7.x上的组安装失败的说明

要安装属于称为"开发工具"的软件包组的所有软件包，请使用以下命令：

# yum --setopt=group_package_types=mandatory,default,optional groupinstall "Development Tools"

或者

# yum --setopt=group_package_types=mandatory,default,optional group install "Development Tools"

在Red Hat Enterprise Linux 7/CentOS 7中更改了yum。
软件包组Development Tools仅包含可选软件包，默认情况下不会安装这些可选软件包。
因此，我们将需要传递选项--setopt = group_package_types = mandatory，default，optional来安装可选软件包。

验证您在CentOS/RHEL 7服务器上的gcc安装

键入以下命令以查看gcc位置：

$ whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz

键入以下命令以查看gcc编译器版本：

$ gcc --version
gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-16)

使用foo.c程序测试gcc C编译器示例

创建一个名为foo.c的文件，如下所示：

#include<stdio.h>
int main(void){
	printf("Hello World!\n");
	return 0;
}

要将foo.c编译为foo可执行文件，请输入：

$ cc foo.c -o foo

要执行foo程序，请输入：

$ ./foo
Hello World!

关于在CentOS 6/7上安装手册页的说明

使用yum命令，如下所示：

$ ## [ CentOS 7 ] ##
$ sudo yum install man-pages man-db man
$ ## [ CentOS 6.x ] ##
$ sudo yum install man man-pages
