Resulting errors:
Undefined symbols for architecture x86_64:
  "ROOT::GenerateInitInstance(Event const*)", referenced from:
      ___cxx_global_var_init.1 in event.o
  "typeinfo for Event", referenced from:

  NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.
