Hi,

I have recompiled root with

--enable-pythia6 --with-pythia-libdir=$KITS_DIR/pythia6

recompiled geant3_vmc_1.10

but the keep crash with the same error

/sps/opera/scratch/dusini/sw/OpRelease/3.1/OpSim/v7r4/Linux/opsim.exe: symbol lookup error:
/sps/opera/scratch/dusini/sw/OpRelease_fluka/kits/geant3_vmc_1.10/lib/tgt_linux/libgeant321vmc.so: undefined symbol: _ZN10TVirtualMC14DefineParticleEiPKc15TMCParticleTypeddd

This error occur at the point where I define a new particle

// DefineParticle(PDGCode, Name, Type, Mass, Charge, Lifetime) gMC->DefineParticle(kOpPDGDPlus, "OPERA D +", kPTMuon, kOpMassDPlus, 1., 1e+12);

where gMC is a TGeant3TGeo object.

regards,
Stefano
