Spack is an excellent package manager with excellent facilities for building and installing packages.

However, for building software that is going to run in a Grid environment, encourage use of binary package distribution, and to assist our users who are migrating from UPS packaging, we have several recommendations and tools, included in this repository.

We have a more complete Spack Tutorial, done initially for Mu2e Spack Tutorial.pdf

Getting Started

The current recommendation is to use our bootstrap script to install spack, for one of our releases:

• pick a directory path where you want to place your spack instance

• fetch a release branch of our bootstrap script with wget or curl, one of

  • v2.23.0 -- latest, defaults to v0.23.0-fermi
  • v2.21.0 defaults to v0.21.0-fermi
  • v2.20.0

• run "bootstrap.sh /path/to/directory"

• Get a cup of coffee or your favorite beverage

• source /path/to/directory/setup-env.sh
