ROOT
#1

Hi

I am having this problem - My code compiles ok, but when running, I get this

[quote]Error in TClonesArray::SetClass: called with a null pointer

*** Break *** segmentation violation
[/quote]

I attach the makefile and the main .cc code

thanks in advance

Hi,

This error message indicates that ROOT does not know about one of the class name that has been passed to the TClonesArray (in the trunk, the error message has been updated to indicate which class name is the problem).

Make sure you have properly spelled each of the class name and that you have a dictionary for each of them.

Cheers,
Philippe.
