circular library dependence

Reported by: rhatcher Owned by: jwolcott
Priority: major Milestone:
Component: Framework Version:
Keywords: Cc:


genie::exceptions::EVGThreadException introduces a circular library dependence: (defined in EVGCore lib, used by GInteraction). This leads to the 'genie' script's (i.e. root $GENIE/src/scripts/gcint/genie_interpreter.C) failure to load all the libraries.

  • Owner changed from candreop to jwolcott
  • Status changed from new to assigned

This was at least partially my fault (I introduced the usage of the exception into src/Interaction/KPhaseSpace.cxx). But after writing a separate exception class that lives in src/Interaction and using that instead in r6352 (which removes the dependence of GInteraction on EVGCore), there seems to be another dependency issue blocking the use of the genie script:

which implies that GUtils depends on GNuclear. Looking into this too.

Yep, looks like r6102 introduced another circular dependency because src/Utils/NuclearUtils.cxx now depends on src/Nuclear/NuclearModelI (needs to check whether the nuclear model is LFG or not), and many things in src/Nuclear also depend on src/Utils/NuclearUtils. Hmm...

  • Resolution set to fixed
  • Status changed from assigned to closed

I was able to fix this by moving NuclearModelI to a new directory, Interfaces/, and by moving NuclearModel to a different new directory, Types/, neither of which is built into a library. See r6353.
