Setting the Environment Variables

Setting the ROOTSYS and PATH Variables

   export ROOTSYS=/root   (in bash or ksh)
   setenv ROOTSYS /root   (in csh or tcsh)

   export PATH=$PATH:$ROOTSYS/bin        (in bash or ksh)
   set path=($path $ROOTSYS/bin)         (in csh or tcsh)

Setting the Library Path

On HP-UX, before executing the interactive module, you must set the library path:

export SHLIB_PATH=$SHLIB_PATH:$ROOTSYS/lib                   (in bash or ksh)
setenv SHLIB_PATH ${SHLIB_PATH}:${ROOTSYS}/lib        (in csh or tcsh)

On AIX, before executing the interactive module, you must set the library path:

[ -z "$LIBPATH" ] && export LIBPATH=/lib:/usr/lib
export LIBPATH=$LIBPATH:$ROOTSYS/lib

or the equivalent setenv.

On Linux, Solaris, Alpha OSF and SGI, before executing the interactive module, you must set the library path:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib

or the equivalent setenv.

On Solaris, in case your LD_LIBRARY_PATH is empty, you should set it like this:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib:/usr/dt/lib

where $ROOTSYS is an environment variable pointing to the ROOT directory. For example, if you use the HPUX-10 AFS version (see below), you should set:

export ROOTSYS=/afs/cern.ch/na49/library.4/ROOT/v2.23/hp700_ux102/root      (in bash or ksh)
setenv ROOTSYS /afs/cern.ch/na49/library.4/ROOT/v2.23/hp700_ux102/root       (in csh or tcsh)

To run the program just type: root.
