Prerequisites

XCode, command line tools and git & github account

• See here for a step by step instructions for XCode and command line tools
• Install homebrew and git:

Homebrew

• Useful pages: brew.sh
• Install...

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$ brew doctor

More packages we will use

• Git https://git-scm.com
• CMake https://cmake.org
• gfortan (part of gcc these days)
• Boost http://www.boost.org

$ brew update
$ brew install git
$ brew install cmake
$ brew install gcc
$ brew install boost --build-from-source

GitHub

• Open a free account on https://github.com
• I recommend installing GUI software for interactions with Git: SourceTree
• In the next section<user> with yout GitHub username

HepSoft

• Fork https://github.com/matplo/hepsoft
• Clone and try to follow the installation instructions - note: below we assume things land in $HOME/devel
• HepMC - note, we will use a 2.X version - not the newest (to be updated)
• Pythia8 Pythia8.2 online documentation
• LHAPDF - note we are also using a rather older version 5.9.1 (this is why we need gfortran)
• FASTJET

If you do not have ROOT (including CMake things)

• ROOT@CERN
• install_all.sh will install a fixed version of ROOT and FastJet
• the installed packages land in $HOME/software/hepsoft by default

$ mkdir -p $HOME/devel
$ cd $HOME/devel
$ git clone https://github.com/<user>/hepsoft
$ cd hepsoft
$ ./bin/build.sh --all --download --build --module

OR for the last command (note you can go one by one... better visibility as of what really went ok...):

$ ./bin/build.sh cmake boost cgal hepmc lhapdf fastjet fastjet_contrib root pythia8 --download --build --module

If you do have ROOT

• Make sure the environment is setup...

$ ./bin/build.sh hepmc lhapdf fastjet fastjet_contrib pythia8 --download --build --module

First steps with PYTHIA + ROOT

• IF the above works try this
