Dear Raphaël To be able to assist you, you need to provide some information on your system (os, compiler etc) and which version of GENIE you are trying to install. cheers Costas On 30 Oct 2012, at 14:43, dupre wrote: --- Dr. Constantinos (Costas) Andreopoulos Staff Scientist Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory Particle Physics Dept.

Yet, there is always a chance that the problem comes from some old files remaining somewhere and missed by make clean, I will check that. Yes I use LHAPDF as default.

Changes in code that links one src area to another can disrupt linkage. I've had trouble with LHAPDF and Pythia at times. Are you using LHAPDF as default instead of Cernlib?

Would you know about any incompatibilities, which would have appeared recently with a new version of one of the software or libraries used by genie? The error message is puzzling to me since he misses some functions that seem to be correctly declared and linked. I past the error here in case you already know this problem or if I miss something obvious: > g++ -Wall -fPIC -O2 -Wno-strict-aliasing -ffriend-injection -c gEvGen.cxx -I/projet/nucleon/dupre/Software/root/include -I/usr/include/libxml2 -I/projet/nucleon/dupre/Software/log4cpp/install/include -I/projet/nucleon/dupre/Software/lhapdf-5.8.8/install/include -I/projet/nucleon/dupre/Software/genie/src/ > g++ -g gEvGen.o -L/projet/nucleon/dupre/Software/genie/lib -lGAlgorithm -lGBaryonResonance -lGBase -lGBodekYang -lGCharm -lGCoh -lGDfrc -lGDIS -lGCrossSections -lGDecay -lGElas -lGElFF -lGHEP -lGEVGCore -lGEVGModules -lGEVGDrivers -lGGiBUU -lGHadronTransp -lGFragmentation -lGInteraction -lGLlewellynSmith -lGMEC -lGMessenger -lGNuGamma -lGNuE -lGNtuple -lGNuclear -lGNumerical -lGQPM -lGPDG -lGPDF -lGQEL -lGRES -lGRegistry -lGReinSeghal -lGUtils -lGGeo -lGFluxDrivers -lGMuELoss -L/projet/nucleon/dupre/Software/root/lib -lGui -lCore -lCint -lRIO -lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics -lMathCore -lThread -pthread -lm -ldl -rdynamic -lMinuit -lGeom -lEG -lEGPythia6 -L/projet/nucleon/dupre/Software/pythia6/v6_412/lib -lPythia6 -L/projet/nucleon/dupre/Software/RADGEN -lradgen /projet/nucleon/dupre/Software/RADGEN/radgen.o -L/cern/pro/lib -lpawlib -lpacklib -lkernlib -lmathlib -L/projet/nucleon/dupre/Software/lhapdf-5.8.8/install/lib -lLHAPDF -L/usr/lib/x86_64-linux-gnu -lxml2 -L/projet/nucleon/dupre/Software/log4cpp/install/lib -llog4cpp -lnsl -o /projet/nucleon/dupre/Software/genie/bin/gevgen > /projet/nucleon/dupre/Software/genie/lib/libGEVGDrivers.so: undefined reference to `genie::AlgFactory::Instance()' > /projet/nucleon/dupre/Software/genie/lib/libGEVGCore.so: undefined reference to `genie::GHepRecord::NEntries(int, int) const' > /projet/nucleon/dupre/Software/genie/lib/libGUtils.so: undefined reference to `genie::NuclearData::DeuteriumSuppressionFactor(double)' > > ... > -- Raphaël Dupré Institut de Physique Nucléaire d'Orsay -- Scanned by iCritical.
