While writing simple macros or python scripts can be an effective way to quickly
get started with ROOT, cases frequently arise where it would be most effective
to create a library of compiled functions or even a compiled executable. Here is
the setup of a template package for compiling ROOT-dependent C++ classes and applications.
- First, determine which ROOT installation you will use.
On lxplus5 (i.e., slc5 operating system), set environment variables with values like these:
export ROOTSYS=/afs/cern.ch/sw/lcg/app/releases/ROOT/5.22.00d/i686-slc5-gcc43-dbg/root
export LD_LIBRARY_PATH=${ROOTSYS}/lib:/afs/cern.ch/sw/lcg/external/Python/2.5/i686-slc5-gcc43-opt/lib:${LD_LIBRARY_PATH}
export PATH=${ROOTSYS}/bin:/afs/cern.ch/sw/lcg/external/Python/2.5/i686-slc5-gcc43-opt/bin:${PATH}
export PYTHONPATH=$ROOTSYS/lib
- Second, go home
