mkLCGCMTtar Overview

mkLCGCMTtar

• the script is using /tmp as intermediate storage space, a lot is required so do not run it on lxbuild.
• the list of external packages required by a given version of a PROJECT (usually GAUDI) is retrieved from the list of native_versions recognized by the PROJECT
• the list of externals, not used directly by the PROJECT, must be append at the end of the ProjectSys (usually GaudiRelease) requirements file with a LHCb or LHCbGrid tag.
• CMTPROJECTPATH must be set beforehand if the PROJECT is built with InstallArea.

Usage

def help() :
  print """make a LCGCMT tar file for a given Gaudi version with the necessary libraries\n
  Usage:
    python mkLCGCMTtar.py -n  -b [-d or --debug] [--plugins]\n
    -d                                     - debug mode \n
    -b or --binary=  <binary>              - for this binary platform \n
    -n or --native=  <Lb project_vers>     - application version from where to get native.versions \n
    --plugins                              - if there: build a PLUGINS tar file \n
  Examples:
    cd $LHCBTAR/source
    python mkLCGCMTtar.py --native=GAUDI_<version> --binary=slc3_ia32_gcc323 \n
    gets the libraries used by GAUDI_<version> from $LCG_release_area/LCGCMT/LCGCMT_version used by Gaudi>\n
    python mkLCGCMTtar.py --plugins \n

  sys.exit()

Full description

• main gets the arguments from the command line, retreives the list of native_versions, gets corresponding tar files and buids the final LCGCMT_<version>_<binary>.tar.gz file.
  • get_native_versions
    • retreive the CMTPATH value either from <version>Env package or with CMTPROJECTPATH
    • get the LCGCMT version from CMTPATH
    • write the full list of native_versions, depending on the required binary, on a temporary file
      • on win32 : add LHCb and WIN32 tags
      • on slc3 : add LHCb, LHCbGrid,slc3 tags
      • on slc4 : add LHCb, LHCbGrid tags
    • build a packages_versions dictionary: {pack,version}
    • remove the temporary file
  • get_tar_files
    • build a temporary tree in /tmp: LCGCMT_<lcg_version&gt:/<binary>/external
    • for every package in packages_versions dictionary
      • get the tar file name from get_tar_name
        • get_tar_name tries to get tar files from LCG tar files distribution
          • LCG packages and ROOT are taken in debug mode
          • AIDA exists only in share mode
          • checks that the tarfile exists, if not checks with package name in lower case
          • if tar file exists returns tarfile name and binary for this tarfile otherwise returns None
        • if tarfile name is None tries to find a private tar file from $LHCBTAR/source
          • if there is none : fill the missing dictionary with {pack:version}
        • if tarfile exists:
          • untar it in the temporary directory * in case of error: fill the tarko dictionary with {pack:version}
          • replace old slc4_ia32_gcc345 binary name with slc4_ia32_gcc34 if any
          • remove doc , test , tests , examples , tutorial directories
          • remove softlinks which cannot be resolved (cernlib/2005)
    • clean_clhep_dir : keep only required libraries
    • make the final tar file from /tmp/LCGCMT_<lcg_version>/lt&;binary>/external
    • if OK:
      • remove temporary tree and print a message
    • if not OK:
      • print missing and tarko dictionaries
      • does not remove temporary tree
