In this article I will accept yous through the steps to install GCC on CentOS 7. As per GCC Certificate ,The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Ada, Go, and D, also as libraries for these languages (libstdc++,...).

Stride 1: Prerequisites

a)Y'all need to have a running CentOS 7 System.
b)Too you lot need to have wget installed in your system with internet connection.
c)Lastly you demand to login with root access or user with sudo access to run gcc installation commands. In this tutorial, I am using root access.

Step 2: Update Your Organisation

Firstly you need to update your system using yum update command. This command volition update all the currently installed packages in your system to the latest available version.

[root@localhost ~]#          yum update          Loaded plugins: fastestmirror Determining fastest mirrors * base: mirrors.piconets.webwerks.in * extras: mirrors.piconets.webwerks.in * updates: mirrors.piconets.webwerks.in base | 3.6 kB 00:00:00 extras | 2.9 kB 00:00:00 ....................................

Footstep 3: Download and Install GCC from Repository

Download from Repository and install gcc tool using yum install gcc control.

[root@localhost ~]#          yum install gcc          Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base of operations: mirrors.piconets.webwerks.in * extras: mirrors.piconets.webwerks.in * updates: mirrors.piconets.webwerks.in Resolving Dependencies --> Running transaction check --->          Package gcc.x86_64 0:4.8.5-39.el7 will be installed          --> Processing Dependency: cpp = 4.8.5-39.el7 for package: gcc-4.8.5-39.el7.x86_64  .........................................

Step 4: Install from Source Lawmaking.

In that location is another method that you tin can use to install gcc tool in your system, that is through source lawmaking which is also the recommended way to install.

Download Source Code

Download GCC Source File from GNU FTP Site using wget. It volition download gcc package in local directory.

[root@localhost ~]#          wget https://ftp.gnu.org/gnu/gcc/gcc-9.2.0/gcc-9.2.0.tar.gz          --2019-12-31 04:47:37-- https://ftp.gnu.org/gnu/gcc/gcc-9.2.0/gcc-9.2.0.tar.gz Resolving ftp.gnu.org (ftp.gnu.org)... 209.51.188.20, 2001:470:142:3::b Connecting to ftp.gnu.org (ftp.gnu.org)|209.51.188.20|:443... connected. HTTP asking sent, pending response... 200 OK Length: 124304709 (119M) [application/x-gzip] Saving to: 'gcc-9.2.0.tar.gz'  100%[==============================================================================================================================>] 124,304,709 ii.83MB/due south in 49s  2022-12-31 04:48:27 (two.43 MB/s) - 'gcc-9.ii.0.tar.gz' saved [124304709/124304709]

Excerpt the Files

Once downloaded, you need to extract the gcc package by using tar -xvf gcc-9.two.0.tar.gz command.

[root@localhost ~]#          tar -xvf gcc-nine.2.0.tar.gz        

Build the Configuration

Once extracted go to gcc-ix.2.0 directory by doing cd gcc-ix.2.0 and run ./configure.

[root@localhost ~]#cd gcc-nine.2.0          [root@localhost ~]#./configure        

Compile the Source Code

One time configuration completed successfully, now it is time to compile the source code by running brand control.

[root@localhost ~]#make        

Install GCC Using make

Once all the source code are compiled, it is now time to install them using brand install command.

[root@localhost ~]#make install        

NOTE:

As per make man page, The purpose of the make utility is to determine automatically which pieces of a large program need to be recompiled, and issue the commands to recompile them. The manual describes the GNU implementation of make, which was written by Richard Stallman and Roland McGrath, and is currently maintained past Paul Smith. Our examples evidence C programs, since they are most mutual, but you lot tin use make with any programming linguistic communication whose compiler tin be run with a shell command. In fact, make is non express to programs. You tin can utilize information technology to draw any task where some files must exist updated automatically from others whenever the others change.

Step 5: Check GCC Version

Once GCC is installed in your arrangement, y'all tin can cheque the gcc version by using gcc --version control.

[root@localhost ~]#          gcc --version          gcc (GCC) 4.8.v 20220623 (Red Lid 4.8.5-39) Copyright (C) 2022 Complimentary Software Foundation, Inc. This is free software; come across the source for copying conditions. In that location is NO warranty; not even for MERCHANTABILITY or Fettle FOR A Item PURPOSE

Step vi: Write Your first C Programme

Since that we have installed GCC Compiler now, allow'south write our Beginning "Hello World" C Program.

[root@localhost ~]#          cat how-do-you-do.c          #include <stdio.h> void main() {          printf("Hello Globe\n");          }

Let'due south Compile this Plan.

[root@localhost ~]#          gcc -o hello hello.c        

Check the Output. Information technology shows Hello World in the output.

[root@localhost ~]#            ./how-do-you-do          Hello World
