Subjects

News

  • ROOT 5.16/00 about to be released.
    Philippe: there will be another bug-fix: 5.14.00g (for gfal protocol)
    Because of problems in the nightlies, it was not possible to test the new version, but it seemed not too bad.
  • A new major version of Geant4 (9) is being prepared an should be ready by the end of July. To be tested.

Software Releases

Gaudi (Hubert)

  • Problem with the distribution for win32. The Python LCG tar-ball was not consistent with the AFS directory, in particular because of a DLL file that is now used by GaudiPolicy to merge rootmap and genconf files.
    The tar-balls have been remade.
  • Fix in install project
  • Full stack build for all platforms

LHCb, Boole, Brunel (Marco Ca.)

  • In the T-Rec meeting as been decided that we will need a new iteration (Brunel, etc.) in 2 weeks, sill based on Gaudi v19r4

Gauss (Gloria)

  • Preparing new Gauss based on Gaudi v19r4 and Geant4 8.3

DaVinci

Philippe: In the stripping tests, 2/3 of the job failed during finalization (not simply reproducible). Patrick is investigating.

OnLine

  • Policy for the packaging of Online:
    • Whatever needs to be released will go into tar-balls
    • Avoid proliferation of applications
  • Released on amd64 (only 4 packages... the others do not compile)
  • Hubert: problems building on win32, Oracle was missing in the LCGCMT tar-ball (win32 only).

Panoramix

Thomas will test Panoramix on Win32 as soon as available.

Round Table

Marco Cl.
LCG_Settings in LCGCMT 52a are breaking the SLC3 on SLC4 cross compilation (building of slc3 binaries on slc4 machines). The problem is that the tag "slc4" is implied by a tag defined by CMT and used in GaudiPolicy (combined to gcc323) to define the name of the compiler, which is wrong in case of cross compilation. I have a work-around if needed, but the problem will be fixed in LCG_Settings.
Thomas
What about Panoramix on MAC?
LCG is not yet ready. We will ask for support for osx_ia32 only. We need to make our software compile on gcc 4.0 (Marco Cl. already did the exercise for 4.1 and has got a patch ready to be applied).
