This doc does not describe building HLT in great detail but it is rather a record of one successful build session. I usually work on the hltlibr account. The build scripts are located in /afs/cern.ch/atlas/project/hlt/admin/bin

• Go to ~/work/hlt-build and copy one of the existing directories to the new lets say HLT-02-00-01. Update the requirements, run cmt config.

• Packages to be built are specified in /afs/cern.ch/atlas/project/hlt/admin/packages/HLT-02-00-01. Either edit by hand or generate a new from template
  • export PATH=/afs/cern.ch/atlas/project/hlt/admin/bin:$PATH
  • get_latest_packages nightly HLT-02-00-01
  • mv HLT-02-00-01 /afs/cern.ch/atlas/project/hlt/admin/packages
  • if external patches are needed compile them in /afs/cern.ch/atlas/project/hlt/external_patches/HLT-02-00-01
  • build_everything --release HLT-02-00-01 --clean
  • tag_release HLT-02-00-01 (has to be done as an identity having necessary CVS rights)

• Validation by testsuite
  • cd /tmp/hltlibr
  • ~/scripts/run_testsuite_www HLT-02-00-01 i686-slc3-gcc323-dbg
  • ~/scripts/run_testsuite_www HLT-02-00-01 i686-slc3-gcc323-opt

• Web pages update
  • add the release entry to /afs/cern.ch/atlas/project/hlt/admin/www/index.phtml
  • create setup-02-00-01.html
  • update HltReleaseNotes

• Kit preparation
  • driven by requirements in ~/cmthome, do cmt config and . ./setup.sh there
  • /afs/cern.ch/atlas/project/hlt/admin/bin/hlt_kit.sh -r HLT-02-00-01
  • hlt_kit.sh uses slightly modified offline tools to build the kit
  • move the files to /afs/cern.ch/atlas/project/hlt/admin/www/pacman
  • The installation instructions are HltDistribution
