[g4star] Update stacker and agml extension classes to enable multi engine tracking and user defined hits in the geant4 application. Few additional fixes and cleanups in the code. [g4star] Import the StGeant4Maker into the repository. Builds under root 6.24 (with some additional compilation flags). [g4star] Defer mysql load until StBFChain can do it. [g4star] Add geant4vmc, geant4mk and fastjet chain options. Load libfastjet with stargen package b/c one or more filters depends on it. (Should consider splitting filters into sep chain opt). [g4star] Cleanup commented out includes. [g4star] Reduce compile time warnings... [g4star] ... more reduction of compiler warnings ... and even more reduction of compiler warnings... [g4star] And modify cons to pickup the include paths to geant4 and geant4 vmc libraries

AgMLBTofVolumeId and similarly named classes implement the unique volume IDs defined in pams/sim/g2t/g2t_volume_id.g. They provide the unique associated between hits and hardware channels.

AgStarDummy inserts a few dummy routines (mangled to look like FORtran routines) which satisfy dependencies between the StarGenerator package and starsim.

The GEANT3 VMC took use of both the "user" and "framework" extensions to TGeoVolume, leaving us with the only option of keeping a map between volume names and extension data.

I assume you are referring to the "volume ID" classes? No. These are new classes to support the geant4star application. |

If you have a chance please try to build with this dependencies Geant3-3-9-p1 is currently missing from the spack repo so, I'll need to add it |

Hi Dmitri,
Will do. The changes in Geant3-3-9-p1 are w/ respect to sensitive
detector functionality,
not interface, so building against it will at least allow me to test a
pure G4 simulation.
Thanks,
Jason

geant3@3-9-p1 is also available on the SDCC machines now. So, the following modules can be used for testing: |

With the last three pushes, code compiles and runs the TPC to completion. Albeit with no hits generated. Reason TBC. |

Draft PR for geant4star. Supersedes #617.
Branch was rebased against current main (02/21/24). Plus few additional fixes to get it to run (up to loading G3) in the current environment.
NOTE: The code should be functional, but requires two modules which we don't currently have in spack, plus an update to a newer version of the geant4 library. Specifically, we need to add a GEANT3 VMC library, and update the Geant 4 VMC library to one which supports multi-engine simulations.
These versions have been tested together by the VMC team.
I should also mention that we are at a point of divergence in the ROOT / VMC development. Currently we are using the VMC version 1.1, which is built with ROOT. The next version is 2.0, which is shipped separately. The GEANT3 VMC 3.9p1 release includes fixes to sensitive volumes which we require, and is the last version able to run with VMC 1.1. Any move to a new version of ROOT, VMC and/or Geant (either G3 or G4) likely entails advancing to a new version of all of these packages... with the possible exception of ROOT.
Code compiles against root 6.24 in our production environment:
