How To Install libint2 on Fedora 36

In this tutorial we learn how to install libint2 in Fedora 36. libint2 is A library for efficient evaluation of electron repulsion integrals

Introduction

In this tutorial we learn how to install libint2 on Fedora 36.

What is libint2

LIBINT computes the Coulomb and exchange integrals, which in electronic structure theory are called electron repulsion integrals (ERIs). This is by far the most common type of integrals in molecular structure theory. LIBINT uses recursive schemes that originate in seminal Obara-Saika method and Head-Gordon and Pople’s variation thereof. The idea of LIBINT is to optimize computer implementation of such methods by implementing an optimizing compiler to generate automatically highly-specialized code that runs well on super-scalar architectures.

We can use yum or dnf to install libint2 on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install libint2.

Install libint2 on Fedora 36 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

After updating yum database, We can install libint2 using dnf by running the following command:

sudo dnf -y install libint2

Install libint2 on Fedora 36 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

After updating yum database, We can install libint2 using yum by running the following command:

sudo yum -y install libint2

How To Uninstall libint2 on Fedora 36

To uninstall only the libint2 package we can use the following command:

sudo dnf remove libint2

We can use `yum` or `dnf` to install `libint2` on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install libint2.

## Install libint2 on Fedora 36 Using dnf

Update yum database with `dnf` using the following command.

```bash
sudo dnf makecache --refresh
