Getting Started

Please fill out the following information to help in answering your question

Geant4-11.2.2
Mac OS
Sonoma 14.4

I know at
https://geant4userdoc.web.cern.ch/UsersGuides/InstallationGuide/fo/Geant4InstallationGuide.pdf
It makes clear that Package Managers are not supported by Geant4 developers

In the past I have used brew on my Mac and they no longer provide a formula for Geant4
so I have just tried spack ( Which I have never used before ) and not having success.

So hence my question anybody successfully installed Geant4 using spack?

Thanks

What problems are you seeing with the spack install? Can take a look here first, but we may want to push upstream depending on the issue.

Trying a workaround

pip install clingo

Okay pip install clingo gets further but then hits other fetch errors

I’ve tried installing just the data in a fresh spack checkout (so not Homebrew installed) and it worked for me. All I can suggest is trying a non-Hombrew install, and if the problem persists, raise a spack Issue or Discussion (There’s also the Slack Channel if you use that).
