The Beginner’s Guide to Building Your First RPM Package

If you’re starting your journey in the world of Linux and have chosen the Red Hat ecosystem, one of the fundamental skills you’ll need to master is the creation of RPM packages. This guide will walk you through the process step-by-step, helping you to understand RPM packaging and how you can build your own RPM package, even as a beginner.

What is an RPM Package?

RPM stands for Red Hat Package Manager. It’s a powerful system used for managing the installation, updating, and removal of software packages in Linux distributions like Fedora, CentOS, and of course, Red Hat. RPM is designed to handle everything from binary files, libraries, to configuration files, providing a comprehensive way to distribute and manage software.

Step 1: Setting Up Your Environment

Before you can start building your RPM package, you’ll need to set up your development environment. For this guide, we’ll assume you’re using a CentOS system. Install the RPM development tools by running:

sudo yum install rpmdevtools 

Next, set up your RPM build environment with:


This command creates a directory structure in your home directory under ~/rpmbuild. The structure includes directories like BUILD, RPMS, SOURCES, SPECS, and SRPMS, each serving a specific purpose in the packaging process.

Step 2: Creating the SPEC File

One of the most crucial parts of the RPM package building process is creating the SPEC file. This file provides a description of the package, the process to build it, and the list of files to be included. Create your SPEC file in the ~/rpmbuild/SPECS directory:

cd ~/rpmbuild/SPECS 
nano myprogram.spec 

Here’s a simple SPEC file for a basic “Hello World” program written in C:

Name: hello_world
Version: 1.0
Release: 1%{?dist}
Summary: A simple Hello World program

License: GPLv3+
Source0: %{name}-%{version}.tar.gz

BuildRequires: gcc

A simple Hello World program written in C.

%setup -q

gcc -o hello hello.c

install -m 0755 hello $RPM_BUILD_ROOT/usr/local/bin/hello



* Mon Jun 12 2023 Your Name 
- First release

This SPEC file will build a binary RPM package from a tarball (tar.gz file) named “hello_world-1.0.tar.gz” that contains the source code file hello.c.

Step 3: Building the RPM Package

Once your SPEC file is ready, you can start the RPM package building process. Run:

rpmbuild -ba myprogram.spec 

This command will create both binary and source RPMs. The ‘-ba’ option tells rpmbuild to build both types of packages.

Step 4: Testing the Package

Once you’ve built your package, you’ll find the resulting RPM file in the ~/rpmbuild/RPMS directory. You can install it with:

sudo rpm -ivh ~/rpmbuild/RPMS/x86_64/hello_world-1.0-1.el7.x86_64.rpm 

Congratulations, you have successfully built and installed your first RPM package!

Wrapping Up

The process of creating an RPM package involves several steps, from setting up your environment and creating a SPEC file to actually building and testing the package. While this guide provides a beginner-friendly introduction, RPM packaging is a vast topic with many more advanced aspects to learn.

As you continue your journey with RPM, you’ll likely encounter complex packages with dependencies, scripts, and intricate build procedures. Don’t be discouraged – with practice, patience, and a continued desire to learn, you’ll soon master the art of RPM packaging. Happy building!
