Installing OR-Tools for .Net from Binary on Linux

Introduction

This guide explains how to install OR-Tools for .Net on Linux.

Although these instructions might also work on other Linux variants, we have only tested them on machines meeting the following requirements:

• Ubuntu 21.10/20.04 LTS/18.04 LTS/16.04 LTS 64-bit (x86_64)
• Alpine Edge 64-bit (x86_64)
• Centos 7 64-bit (x86_64)
• Centos 8 64-bit (x86_64)
• Debian 10.10 (buster) 64-bit (x86_64)
