How to Install CMSSW on Ubuntu

System

• Laptop: Dell Latitude E6500
• OS: Kubuntu 8.04 (64 bit)
• Shell: BASH
• Memory: 4 Gb
• CPU: Intel Core2 Duo T9400 @ 2.53GHz

One time initialization of the software area (LCG style)

• Choose and create installation directory, for example

  mkdir -p $HOME/local/cmssoft/cms

• Set environment variables:

  export VO_CMS_SW_DIR=$HOME/local/cmssoft/cms

  export SCRAM_ARCH=slc4_ia32_gcc345

  export LANG="C"

• Download the bootstartp.sh script which is used to setup and initialize a CMS software area:

  wget -O $VO_CMS_SW_DIR/bootstrap.sh http://cmsrep.cern.ch/cmssw/cms/bootstrap.sh

• This set depends on a directory /tmp/$USER being already present. If not

  mkdir /tmp/$USER

• Initialize software area:

  bash -x $VO_CMS_SW_DIR/bootstrap.sh setup -path $VO_CMS_SW_DIR -arch $SCRAM_ARCH -unsupported_distribution_hack -v >& $VO_CMS_SW_DIR/bootstrap_$SCRAM_ARCH.log

  source $VO_CMS_SW_DIR/$SCRAM_ARCH/external/apt/*/etc/profile.d/init.sh

  apt-get update
