CERN and ROOT Scripts

The CERN and ROOT scripts provide the user with a way to automatically set up an environment condusive to the use of ROOT and CERN libraries of a specific version.

The scripts are setup_cern.sh and setup_root.sh and they are located in the /net/cern directory. Users can either call them directly, download them to a separate directory for customization or installed directly into the user's .bash_profile startup script.

The contents of the setup_cern.sh is as follows:

#!/bin/bash
#
# setup_cern.sh
#
# This script sets up environment variables for the
# CERN libraries, as well as a few common libs.

CERNDIR=/net/cernlib
VERSION="pro"
CERNROOT=$CERNDIR/$VERSION

if test -d $CERNDIR; then
    export CERN=$CERNDIR
fi

export HARDWARE="pclinux"
export hardware="pclinux"

if [ $CERN ]; then
    if [ ! $(echo $PATH | grep $CERNROOT/bin) ] ; then
        export PATH=$CERN/pro/bin:$PATH ; fi
    if [ ! $(echo $LD_LIBRARY_PATH | grep $CERNROOT/lib) ] ; then
        export LD_LIBRARY_PATH=$CERNROOT/lib:$LD_LIBRARY_PATH ; fi
    export packlib=$CERNROOT/lib/libpacklib.a
    export kernlib=$CERNROOT/lib/libkernlib.a
    export mathlib=$CERNROOT/lib/libmathlib.a
    export graflib=$CERNROOT/lib/libgraflib.a
fi

Simply change the VERSION variable to whichever version of the CERN libraries you want. Current versions are old(2000), pro(2000) and new(2002). The default is pro.

The contents of the setup_root.sh script is as follows:

#!/bin/bash

# setup_root.sh
#
# This script sets up certain environmental variables
# to use the ROOT software
#

ROOTDIR=/net/cern
ROOTVER="root-3.05.07"

if test -d $ROOTDIR/$ROOTVER ; then
    export ROOTSYS=$ROOTDIR/$ROOTVER
fi

if [ $ROOTSYS ]; then
    if [ ! $(echo $PATH | grep $ROOTSYS/bin ) ] ; then
        export PATH=$ROOTSYS/bin:$PATH ; fi
    if [ ! $(echo $SHLIB_PATH | grep $ROOTSYS/lib ) ] ; then
        export SHLIB_PATH=$ROOTSYS/lib:$SHLIB_PATH ; fi
    if [ ! $(echo $LD_LIBRARY_PATH | grep $ROOTSYS/lib ) ] ; then
        export LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH; fi
fi

The default version is 3.05.07. Other versions available are root-3.01, root-3.05, root-3.05.07-dev, root-4.00, root-4.00.08 and root-4.02.00. Simply change the ROOTVER variable to match your preference.
