Round Table

Marco Cl.

• CMake
  • Geant4 builds with CMake (CMT compatible)
  • Gauss initial migration completed: to be tuned (issues with Pythia)
• Gaudi
  • v23r10 is a minor bugfix release
  • the next release will focus on the merge between the LHCb and ATLAS branches (will be tagged even if we are not building the LHCb stack on it)

Joel

• First release of BeautyDirac in production

Ben

• Issues with getpack and the french language

After a discussion on the various options, we agreed to set the LANG environment variable to C in few key places:

• LbScripts script baseclass
• gaudirun.py
• GaudiPython (module)

These should cover 99.9% of the use cases without interfering with the user desktop. Note that the changes in Gaudi will be in v23r10 after a retag.
