my own class

Dear ROOTers,

After writing a very simple class, inheriting from a TObject.h, I am trying to link it inside my CMS ORCA code. The compile process of the class is successfull, I cannot say the same for the test program, on the other hand:

The ORCA I am using is necessarly ORCA_8_8_0. Unfortunately, I am not able to say which version of ROOT is in use, since the doc page doesn't load.

Did anybody already meet this problem?

Thanks in advance for your kind help,

Pietro Govoni
