  • OS: Kubuntu 8.04 (64 bit)
  • Shell: BASH
  • Memory: 4 Gb

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 script which is used to setup and initialize a CMS software area:
    wget -O $VO_CMS_SW_DIR/
  • This set depends on a directory /tmp/$USER being already present. If not
    mkdir /tmp/$USER
  • Initialize software area:
    bash -x $VO_CMS_SW_DIR/ setup -path $VO_CMS_SW_DIR -arch $SCRAM_ARCH -unsupported_distribution_hack -v >& $VO_CMS_SW_DIR/bootstrap_$SCRAM_ARCH.log
    source $HOME/local/cmssoft/cms/slc4_ia32_gcc345/external/apt/*/etc/profile.d/
    apt-get update
