Hi Jeff, Yes, I have often gone back to a build and tried to figure out how it was actually built. We're investigating using EasyBuild ( https://github.com/hpcugent/easybuild ) however we haven't taken the plunge yet. We do use Lmod ( https://github.com/TACC/Lmod ) and so I have modules loaded into our environment. All this being said, I wrote a quick and dirty script that logs the modules loaded and the configure line from the config.log to a DB. The script also queries the DB and can produce the configure command (including module loads) and update the prefix based upon the source directory your in (it only does this for patch version updates only (i.e 1.8.4 -> 1.8.5), I decided anything larger than this you really should read the docs/configure options to see if your doing things correctly). It's an ugly script that I'm not proud of but it works! Regards Tim
