Not able to run Delphes on lxplus@cern.ch

[Fabrizio Scuri]

Hello, I followed the instructions in the following websites:
https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/Tutorials/Mc4Bsm
https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/QuickTour

but when I try to lauch any executable (DelphesHepMC, DelphesLHEF, or DelphesSTDHEP) i get the message that the shared lib libMultiProc.so cannot be found. In fact, the only shared object file I can find in the generated directory tree when installing the program are
libDelphes.so and libDelphesNoFastJet.so ....
Thank-you for explanations on how to fix this ..

Hello Fabrizio,

I've just tried the following commands from WorkBook/QuickTour:

ssh lxplus.cern.ch

source /afs/cern.ch/sw/lcg/external/gcc/4.9.3/x86_64-slc6/setup.sh
source /afs/cern.ch/sw/lcg/app/releases/ROOT/6.06.00/x86_64-slc6-gcc49-opt/root/bin/thisroot.sh

wget http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.3.3.tar.gz
tar -zxf Delphes-3.3.3.tar.gz

cd Delphes-3.3.3
make -j 4

rfcat /castor/cern.ch/user/d/demine/test.hepmc.gz | gunzip | ./DelphesHepMC cards/delphes_card_CMS.tcl delphes_output.root

They worked without any problem.

Could it be that some other environment variables (for example, the ones configured in your shell configuration scripts) are pointing to a wrong library location?

Best regards,

Pavel
