*** Break *** segmentation violation Generating stack trace...

Asked by yvonne ng on 2015-08-14

Hi,

So I imported a model,
Added a process and output successfully, but when I try to launch it gives me this error.
online searching tells me that this error is related to C++ and that somethings are not correctly referenced?
I wonder if anyone has ran into this problem before and can tell me what this is caused by.

Hi,

madgraph do not use any C++, so the problem is either in Delphes or in the ExRootAnalysis package (both external package).
Pavel is one author of both package and might be able to help you.

Cheers,

Olivier

Hi it was indeed an Exrootanalysis problem. i reinstalled root after the initial installation and I think that was what that lead to the problem.
Thank you so much for your help!
