Hi, I am using ROOT 3.05/03 in a REDHAT 8.0 Linux PC. I have compiled this using source code. It looked it worked fine. I have a macro which runs fine in another machine which has ROOT 3.00/06. Code is at the end of this message. There is no way to mail the root data file, since it is too big to the roottalk mail server(80 MB). When I tried the same code with ROOT 3.05/03 I get following error. It seems this errors come when the statment nbytes += EVENT->GetEvent(i); is added. How can I get it fixed?
