Building Key4hep: For Librarians
Key4hep comprises a fairly large number of software and depends on even more externals, so some tooling is needed to efficiently build the whole software stack. The spack package manager can be used to build scientific software at scale, and is part of the Key4hep software R&D program.
A spack install of Key4hep is regularly deployed to /cvmfs/sw.hsf.org/, and can be used on lxplus/centos7 just by sourcing the following setup script:
source /cvmfs/sw.hsf.org/key4hep/setup.sh
In this page, the workflow to create this installation is documented.
