如何在RHEL 8/CentOS 8上安装开发工具？
基于RHEL的分布式专为企业和运行关键任务应用而设计。
它是最稳定和最安全的服务器操作系统。
出于安全原因和性能，他们经常预先安装的包装较少。

如果要在RHEL/CONTOS 8上进行开发或者构建开源应用程序，则需要安装包含以下工具的开发工具.AutoConfautomakeGccgcc-C ++ BisonBinutilsgdblibc-devellibtoolmakepkgconfpkgconf-m4pkgconf-pkg-configredhat-rpm-pkg-configredhat-rpm-configrpm-buildrpm- signstrace.

在CentOS/RHEL 8服务器上安装GCC和开发工具

以下命令用于在CentOS/RHEL 8服务器上安装GCC和开发工具。

sudo dnf group install "Development Tools"

或者

sudo dnf groupinstall "Development Tools"

我们可以查看有关的信息 Development Tools包组。

sudo dnf group info "Development Tools"

通过检查工具二进制位置来验证安装。

$whereis bison gcc flex
bison: /usr/bin/bison /usr/share/bison /usr/share/man/man1/bison.1.gz /usr/share/info/bison.info.gz
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz /usr/share/info/gcc.info.gz
flex: /usr/bin/flex /usr/share/man/man1/flex.1.gz /usr/share/info/flex.info-1.gz /usr/share/info/flex.info-2.gz /usr/share/info/flex.info.gz

检查安装的GCC版本。

在CentOS/RHEL 8服务器上卸载GCC和开发工具

下面是用于删除CentOS/RHEL 8上的包组的命令。

sudo dnf group remove "Development Tools"

始终依赖依赖树，以避免打破其他系统包。

测试GCC编译器

让我们创造一个 Hello World程序查看它是否正确编译。

$cat  hello.c
#include <stdio.h>
int main() {
    printf("Hello, world!\n");
    return 0;
}

使用GCC编译代码。

gcc hello.c -o helloworld

运行程序以查看它是否打印 Hello, world!。

$./helloworld 
Hello, world!
