Hi Dipanwita,

I think your problem could be that probably you didn't set the CERN library.

export CERN_ROOT=....

(whereever your CERN library is).

However, there is now another (probably easier) way to run EvtGen,
namely the PndEvtGenDirect, developed by Björn Spruck (but undocumented yet).
I think so far we only have a small tutorial example existing.

http://panda-wiki.gsi.de/cgi-bin/view/Computing/PandaRootCharmoniumTutor ial

under item (3).

PndEvtGenDirect *EvtGen = new PndEvtGenDirect("psi(2S)","PSI2S.DEC");
primGen->AddGenerator(EvtGen);


is how to use it directly in your simulation macro.
You need a few ASCII files (evt.pdl, DECAY.DEC and your own decay file, e.g. PSI2S.DEC in this case), but it is maybe easier than compiling simpleEvtGen.cc.

cheers, Soeren
