Lmod is a tool for managing environment modules on Unix-like systems. It enables users to easily switch between different versions of software packages, compilers, and other tools.

This tutorial will guide you through the process of installing environment-modules Lmod on NetBSD.

Prerequisites

Before you begin, you must have the following:

• A NetBSD system with root access
• An internet connection

Step 1 - Install the pre-requisite packages

Lmod requires certain pre-requisite packages to be installed on the system. Install these packages using the following command:

pkgin update
pkgin install gcc make git

Step 2 - Download Lmod

wget https://github.com/TACC/Lmod/archive/refs/tags/v8.5.19.tar.gz

Step 3 - Extract the downloaded package

Extract the downloaded package using the following command:

tar zxvf v8.5.19.tar.gz

Step 4 - Build and install Lmod

Change directory to the Lmod directory using the following command:

cd Lmod-8.5.19

Configure Lmod using the following command:

Step 5 - Configure Lmod

Configure Lmod by adding the following lines to the end of the /etc/profile file:

## Lmod Modulepath
export MODULEPATH=$MODULEPATH:/usr/local/Modules/modulefiles
export MODULEPATH=$MODULEPATH:/usr/local/Modules/modulefiles/Core

Step 6 - Test Lmod

To test Lmod, load a module using the following command:

module load gcc

Verify that the module has been loaded using the following command:

echo $PATH

You should see /usr/pkg/gcc-10.2.0/bin in the output, indicating that the gcc module is loaded.

Congratulations! You have successfully installed Lmod on your NetBSD system.
