How to Install Spack on OpenBSD

Spack is an open-source package manager for scientific computing that helps simplify the installation and management of software. In this tutorial, we will guide you on how to install Spack on OpenBSD.

Prerequisites

Before we proceed with the installation, make sure that your OpenBSD system is up to date and has the following prerequisite software installed:

• curl
• tar
• perl

Step 1: Install Spack

To install Spack on OpenBSD, we need to download the package archive from the official Spack website using the curl command, extract it using the tar command, and then move the extracted folder to the /opt directory.

1. Open a terminal on your OpenBSD system.

2. Run the following command to create a directory for Spack:

   sudo mkdir /opt/spack
   

3. Download the Spack package archive using the curl command:

   curl -L -O https://github.com/spack/spack/archive/v0.16.2.tar.gz
   

4. Extract the downloaded archive using the tar command:

   tar xvzf v0.16.2.tar.gz -C /opt/spack --strip-components=1
   

5. Set the SPACK_ROOT environment variable to point to the Spack installation directory:

   export SPACK_ROOT=/opt/spack
   

6. Add the spack command to your PATH environment variable:

   export PATH=$SPACK_ROOT/bin:$PATH
   

7. Verify that the installation was successful by running the spack command:

   spack --version
   

   This command should output the version of Spack that you have installed.

Step 2: Configure Spack

1. Run the following command to install any dependencies required by Spack:

   spack bootstrap
   

2. Configure Spack to use the clang compiler by running the following command:

   spack compiler find
   

3. If you wish to use a different compiler, you can install it using Spack by running the following command:

   spack install <compiler_name>
