Installing GCC c and c++

CentOS, Linux / March 27, 2021 / ashishpsk / 0

Command to list groups on a CentOS / RHEL 7

# yum group list

Another option:

# yum group list ids

Command to install GCC and Development Tools on a CentOS / RHEL 7 server:

# yum group install "Development Tools"

If above command failed, try:

# yum groupinstall "Development Tools"

A note about failing groupinstall on CentOS/RHEL 7.x:

To install all the packages belonging to a package group called “Development Tools” use the following command:

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

The yum has changed in Red Hat Enterprise Linux 7/CentOS 7. The package group “Development Tools”” has only the optional packages which by default doesn’t get installed. So we will need to pass the option —

setopt=group_package_types=mandatory,default,optional to install the optional packages too.

Verify your gcc installation on a CentOS / RHEL 7 server:

Type the following command to see gcc location:

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

Type the following command to see gcc compiler version:

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

#include<stdio.h>

	return 0;
}

To compile foo.c into foo executable file, type:

$ cc foo.c -o foo

To execute foo program, type:

$ ./foo
