I have a problem when trying to use a package (ie. Electron.par) which is an Electron class derived from TLorentzVector class. it failed when I enable it with an message:

where I had a reference to mother class in LinkDef header file which looks like: (I attached the .par package if it helps)

Thank you for any helps or comments,

what does ldd /scratch/proofbox/baotran/packages/Electron/./libElectron.so show? You could add it as the last command in the list of commands building libElectron.so in your Makefile.
The main problem is that you do not load libPhysics, the library containing TLorenzVector. Autoload works for classes, not for libraries. Then the warnings about ‘nostubs’ and alike come from the fact that the Makefile that you use must be rather old.
Attached is the fixed PAR file (ElectronMk.par).
However, when you have a simple class, or a set of simple classes depending on each other, you can just load them in SETUP.C as you would do in a normal ROOT session. No need for makefiles, dictionary files, etc.
See Electron.par .
