Disclaimer: The usual nightly restrictions apply when using development versions: a build might have failed, a build might be unavailable for a particular configuration, features might be missing / are not yet in release quality ...

Where to find nightly builds:

• Directory with nightly binaries for various platforms
• CVMFS:
  • Source the relevant setup scripts, such as
    
    • Full LCG software stack, python2: source /cvmfs/sft.cern.ch/lcg/nightlies/dev3/<DAY>/lcgenv/*/<PLATFORM+Compiler>/lcgenv-env.sh
    • Full LCG software stack, python3: source /cvmfs/sft.cern.ch/lcg/nightlies/dev3python3/<DAY>/lcgenv/*/<PLATFORM+Compiler>/lcgenv-env.sh
    • Only ROOT (packages might be missing on your system):
      source /cvmfs/sft.cern.ch/lcg/nightlies/dev3/<DAY>/ROOT/HEAD/<PLATFORM+Compiler>/bin/thisroot.sh
• Gentoo prefix (platform independent):
  Execute /cvmfs/sft.cern.ch/lcg/contrib/gentoo/linux/x86_64/startprefix
