Introduction

In this tutorial we learn how to install OpenNL on Fedora 34.

What is OpenNL

OpenNL (Open Numerical Library) is a library for solving sparse linear systems, especially designed for the Computer Graphics community. The goal for OpenNL is to be as small as possible, while offering the subset of functionalities required by this application field. The Makefiles of OpenNL can generate a single .c + .h file, very easy to integrate in other projects. The distribution includes an implementation of our Least Squares Conformal Maps parameterization method. New version (Concurrent Number Cruncher and Nathan Bell’s ELL formats) OpenNL offers the following set of functionalities Efficient sparse matrix data structure (for non-symmetric and symmetric matrices) Iterative builder for sparse linear system Iterative builder for sparse least-squares problems Iterative solvers Preconditionners Iterative solver on the GPU (Concurrent Number Cruncher and Nathan Bell’s ELL) Sparse direct solvers Simple demo program with LSCM (Least Squares Conformal Maps) OpenNL 3.2.1 27.fc34 x86_64 41 k OpenNL-3.2.1-27.fc34.src.rpm fedora A library for solving sparse linear systems http BSD OpenNL (Open Numerical Library) is a library for solving sparse linear systems, especially designed for the Computer Graphics community.

We can use yum or dnf to install OpenNL on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install OpenNL.

Install OpenNL on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

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

sudo dnf -y install OpenNL

Install OpenNL on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

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

sudo yum -y install OpenNL

How To Uninstall OpenNL on Fedora 34

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

sudo dnf remove OpenNL
