Installing Spack on Fedora CoreOS Latest

Spack is a flexible package manager for scientific software that aims to make installing, compiling, and managing dependencies of scientific computing packages as easy as possible. In this tutorial, we will guide you through the process of installing Spack on the latest version of Fedora CoreOS.

Prerequisites

Before we begin, you will need to have the following:

  • A system running the latest version of Fedora CoreOS
  • Superuser privileges or sudo access
  • An active internet connection

Step 1: Install dependencies

The first step is to install the dependencies needed for Spack. Go ahead and open a terminal window and enter the following command:

sudo rpm-ostree install python3-devel make gcc gcc-c++ git

This command will install the required components for Spack to work correctly.

Step 2: Clone Spack repository

Next, let us clone the Spack repository. In the same terminal window, run the following command:

git clone https://github.com/spack/spack.git

This command will clone the Spack repository to your system's home directory.

Step 3: Set up Spack

Once the cloning process is complete, navigate to the Spack directory using the following command:

cd spack

Now, let us set up Spack. To do so, enter the following command:

./bin/spack bootstrap

The command will create the necessary directories and files for Spack to function.

Step 4: Add Spack to the PATH

For convenience, add Spack to the PATH environment variable. To do so, run the following command:

echo 'export PATH="$HOME/spack/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

The first command adds the Spack directory path to the PATH environment variable. The second command refreshes the bash shell with the updated PATH variable.

Step 5: Verify Spack installation

You have completed Spack's installation process. To verify that the installation is successful, issue the following command:

spack --version

This command should display the Spack version number on your system.

Conclusion

Congratulations! You have successfully installed Spack on your Fedora CoreOS system. You can now use Spack to manage dependencies for scientific packages installed on your system.
