Installation procedure for a minimal set of FairSoft packages, FairRoot and DDS together with an AliRoot installation including Root, Geant3, AliRoot core , and AliPhysics.

Issues

• FairRoot installation fails if the FairSoft packages have been installed in 'reco only' mode, fix is provided in https://github.com/matthiasrichter/FairRoot, and a corresponding pull request has been opened https://github.com/FairRootGroup/FairRoot/pull/191
• FaiRoot needs to find Geant3, additional flag has been added to cmake find, same pull request, flag can be used -DGEANT3_PATH=<path>
• AliceO2 cmake does not find boost unless -DBOOST_ROOT=$SIMPATH has been added
• AliceO2 cmake fails in module Generators because PYTHIA8_INCLUDE_DIR is required

Installation

• root has been omitted from the FairSoft installation by commenting the corresponding lines in configure.sh
• aliroot is compiled with specific options in order to use the GPU tracker -DHLT_CUDA=ON -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-5.5
• using repo https://github.com/matthiasrichter/AliceO2.git
• using Alice Software setup alice-env.sh from D. Berzano
