Hello, I am using the genie MC, but stopped using it since a year or so, now I am unable to compile it any more on my new machine (it crashes at the linking stage). 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
