How to Install Environment-Modules Lmod on Manjaro

Environment-modules Lmod is an alternative to the traditional Tcl-based Environment-modules system for dynamically managing your shell environment on a per-application basis. This tutorial will provide step-by-step instructions on how to install Environment-modules Lmod on Manjaro.

Step 1: Update and Upgrade your System

The first step is to make sure your system is up to date.

sudo pacman -Syu

Step 2: Install Required Packages

Install the packages required to build Lmod:

sudo pacman -S lua readline

Step 3: Clone the Lmod Repo

Clone the Lmod repository:

git clone https://github.com/TACC/Lmod

Step 4: Build and Install Lmod

Build and install Lmod:

cd Lmod
./configure --prefix=/usr
make
sudo make install

Step 5: Update your Shell

Lmod is not yet integrated with Manjaro's system-wide environment. To use Lmod, you'll need to add the following lines to your shell configuration file:

source /etc/profile.d/z00_lmod.sh
alias module='source /etc/profile.d/z00_lmod.sh ; module'

For Bash users, run this command:

echo -e "\nsource /etc/profile.d/z00_lmod.sh" >> ~/.bashrc
echo -e "\nalias module='source /etc/profile.d/z00_lmod.sh ; module'\n" >> ~/.bashrc

For Zsh users, run this command:

echo -e "\nsource /etc/profile.d/z00_lmod.sh" >> ~/.zshrc
echo -e "\nalias module='source /etc/profile.d/z00_lmod.sh ; module'\n" >> ~/.zshrc

Step 6: Verify Lmod Installation

Source your shell config file or open a new terminal window and type:

module avail

If Lmod is installed correctly, you should see a list of available modules.

Congratulations, you have successfully installed Environment-modules Lmod on Manjaro.
