When a new LArSoft release is available and you want to develop against the new LArSoft release

(Stolen from dunetpc wiki)

• Relogin into a sbndgpvm node, do the following\

  source /grid/fermiapp/products/sbnd/setup_sbnd.sh
  setup larsoft vxx_yy_zz -q e14:prof #set up the latest larsoft release
  cd larsoft_mydev
  mrb newDev -p #this creates a new localProducts_XXXX directory using the new larsoft release and the existing srcs directory
  source localProducts_XXXX/setup  #make sure to use the new localProducts directory, it's better to delete the old directory
  cd srcs/sbndcode
  git checkout develop
  git pull
  

• If you are working on a feature branch (ignore if you are working in develop branch):\

  cd srcs/sbndcode
  git checkout develop
  git pull
  git checkout feature/<my feature branch>
  git merge develop
  

• Update all other repositories if they exist in your srcs directory (e.g. larreco)

• Make a clean build\

  cd $MRB_BUILDDIR
  mrb z
  mrbsetenv
  mrb i -j4 #rebuild
