Prerequisites

The following sections describe the prerequisites for installing OR-Tools.

.Net Core SDK >= 3.1

Next, install the .Net Core SDK version 3.1 or higher. To do so, open a terminal window and enter:

AlpineCentosDebianFedoraFedoraOpenSUSEUbuntuUbuntuUbuntu
apk add dotnet6-sdk
    
ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-alpine
 
sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
sudo yum install -y dotnet-sdk-6.0
 ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-centos#centos-7

Before you install .NET, run the following commands to add the Microsoft package signing key to your list of trusted keys and add the package repository.

wget https://packages.microsoft.com/config/debian/11/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
dpkg -i packages-microsoft-prod.deb
rm packages-microsoft-prod.deb
 
sudo apt update
sudo apt install -y dotnet-sdk-6.0
 ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-debian 
sudo dnf install -y dotnet-sdk-6.0
 ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-fedora 
sudo dnf install -y dotnet-sdk-6.0
 ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-fedora

Before you install .NET, run the following commands to add the Microsoft package signing key to your list of trusted keys and add the package repository.

sudo zypper install libicu
sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
wget https://packages.microsoft.com/config/opensuse/15/prod.repo
sudo mv prod.repo /etc/zypp/repos.d/microsoft-prod.repo
sudo chown root:root /etc/zypp/repos.d/microsoft-prod.repo

Then you can install the .Net SDK using the following command:

sudo zypper install -y dotnet-sdk-6.0
 ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-opensuse 
sudo apt install -y dotnet-sdk-6.0
 ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu 
sudo apt install -y dotnet-sdk-6.0
 ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu 
sudo apt install -y dotnet-sdk-6.0
 ref: https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu
