How To Install isl on CentOS 8

isl is Integer point manipulation library Integer point manipulation library

Introduction

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

What is isl

isl is a library for manipulating sets and relations of integer points bounded by linear constraints. Supported operations on sets include intersection, union, set difference, emptiness check, convex hull, (integer) affine hull, integer projection, computing the lexicographic minimum using parametric integer programming, coalescing and parametric vertex enumeration. It also includes an ILP solver based on generalized basis reduction, transitive closures on maps (which may encode infinite graphs), dependence analysis and bounds on piecewise step-polynomials. isl 0.16.1 6.el8 x86_64 841 k isl-0.16.1-6.el8.src.rpm appstream Integer point manipulation library http MIT isl is a library for manipulating sets and relations of integer points bounded by linear constraints.

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

Install isl on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

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

sudo yum -y install isl

How To Uninstall isl on CentOS 8

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

sudo dnf remove isl
