Since the big website revamp, it should be noted that versions of Geant4 prior to 10.4 cannot reach the data to download so you can't compile them with data or use them. For example, they look for it here: https://geant4.web.cern.ch/support/source/G4NEUTRONXS.1.4.tar.gz but more modern versions look here: https://cern.ch/geant4-data/datasets/G4NDL.4.5.tar.gz I only found out as I have a docker image for 10.1 -> latest for testing BDSIM as we technically support them. Practically, 10.4.p04 is the oldest we use as it has the last point where proton diffraction still works. Thankfully, 10.4 works. Just so you're aware. Cheers, Laurie PS didn't find a good category for this, so thought cmake was the best.
This will require a bit of finessing of redirects on the new website, so may take a little while to implement.

It is fixed by Ben.
This is now handled through redirects, and so should work right back to 10.0 (the earliest I've tested).
