Does this mean that  I should be using a newer version than Root 5.14?


Not at all, 5.14 works well with gate3.1.2 version.
When you get "Undefined reference" error messages while linking, that means
that the definition is present in the header file but not in the
corresponding library. I think your problem here is just related to your
environment (assuming ROOT is well installed). Have you fixed the ROOTSYS
environment variable before launching make, have you source the
env_gate.sh/csh file before launching make, have you added the ROOT
libraries path to your LD_LIBRARY_PATH ???

Anyone else encountered this problem?
