You often do not need to care (i.e., you can safely live with these warnings).

In principle, before opening the ROOT file, you should load a shared library that “defines” these classes.
If you do not have the “original” source code for these classes, you may try: TFile::MakeProject

Thank you for your reply. I am a new root user. Kindly how do you load a shared library that defines these classes?

You would need something like: gSystem->Load("/path/to/your/libAllMyClasses.so");

You need to talk to your colleagues and/or supervisor and/or the author(s) of your ROOT files about how to proceed.

Thank you let me work on that.
