How To Install doxygen on CentOS 8

doxygen is A documentation system for C/C++

Introduction

In this tutorial we learn how to install doxygen on CentOS 8.

What is `doxygen`

Doxygen can generate an online class browser (in HTML) and/or a reference manual (in LaTeX) from a set of documented source files. The documentation is extracted directly from the sources. Doxygen can also be configured to extract the code structure from undocumented source files.

We can use yum or dnf to install doxygen on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install doxygen.

Install doxygen on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh
