ExRootAnalysis: no dictionary for class TRootLHEFEvent is available
Hi!
I have installed ExRootAnalysis via the install command in MG/ME. Now when I launch a process I get the following error
[...]
Error in <UnknownClass:
Error in <UnknownClass:

Followed by the requested cross section. The first part about the missing dictionary modules I can get rid of by simply copying them from the tmp-folder into my root installation, but after that I still have an issue with the TRootLHEFEvent dictionary. It seems something has gone wrong in the installation of ExRootAnalysis. My guess is that some files weren't copied to the correct locations...
By the way, I have tried to download ExRootAnalysis directly from the MG webpage and compiling it. When running ExRootLHEFConverter directly on the produced .lhe file, I get exactly the same error.
I run Ubuntu 12.04 (64-bit). I have aslo tried on a machine running MacOSX and have the same problem there.
I hope you can help, and thanks in advance!
