Re: no dictionary

Hi Marc,

are you compiling your code with a Makefile or using aclic? If you are using a Makefile you should not forget to generate the dictionaries from you class header file using rootcint. If you are using aclic the dictionaries should be generated automatically.

But from the warning lines you sent, it seems you are not loading the appropriate shared libs(the one containing the dictionaries) when you try to read a root file containing the objects in question.

Can you send us more information?

Cheers
Marcelo
