[Rivet] undefined symbol: _ZNK5Rivet8Analysis6getLogEv

[James Monk]

Did you build libRivetMyAnalysis.so with the command exactly as it  
shows on the wiki?  I'm sort of surprised that works - I'd expect it  
to complain about undefined symbols.  Surely it needs to know about  
libRivet.so for the base Analysis class, since otherwise how's it  
supposed to know which library to look in at runtime?  (unless it  
already happens to have been linked).  Have you tried loading a  
standard analysis first and then your own, i.e Rivetgun -a  
CDF_blah_blah -a MyAnalysis to see if that makes it pick up the base  
Analysis clase?

What machine are you building this on?
