Re: [VMC] Re: geant3_vmc undefined symbol: _ZN10TVirtualMC14DefineParticleEiPKc15TMCParticleTypeddd

Stefano, looks like your G3 compilation is inconsistent. Just refresh the geant3 directory and recompile it from scratch. Make also sure that the library you compile is the first one accessible in LD_LIBRARY_PATH in case you have multiple versions.

Cheers,
Andrei
