[Rivet] Rivet 2.0.0

[Andy Buckley]

Hi Sarah,

No problem to get in touch, but the rivet at projects.hepforge.org
developer list is the best place to contact when you have trouble: I've
CC'd it now. But this one is actually easiest for me to answer, I suspect...

This issue was actually a problem that I encountered (and was surprised
by) in the tutorial -- for some reason the "-L" flag that specifies
*where* -lRivet will be found was missing from the compiler command
generated by rivet-buildplugin.

I've fixed this on the trunk (it was a very boring typo bug) and it'll
be working properly in Rivet 2.1.0 which we plan to release very soon.
But as a workaround you can add the missing -L to the buildplugin
command as an extra argument for the compiler:

rivet-buildplugin WZanalysis_5fb.cc
-L/afs/cern.ch/sw/lcg/experimental/rivet/local/lib

By the way, it's mostly recommended to use the Genser copy of Rivet
(source
/afs/cern.ch/sw/lcg/external/MCGenerators_lcgcmt65/rivet/2.0.0/x86_64-slc6-gcc46-opt/rivetenv.sh)
rather than that experimental one -- although I think this experimental
copy is exactly version 2.0.0. The main reasons that I used this area in
the tutorial was that I could provide a script that guaranteed all the
compiler setup stuff, and provided a copy of the Sacrifice Pythi8
steering program, too). I should provide a setup for a more standard
installation in future tutorials, especially since there's no guarantee
that we won't break or remove stuff from the experimental area!

Best wishes, and please let us know if you still have any difficulties,
Andy
