geant3_vmc undefined symbol: _ZN10TVirtualMC14DefineParticleEiPKc15TMCParticleTypeddd

Hi

I have upgrade the OPERA simulation software to use root_v5.23 and therefore I changed also the version of geant3_vmc to v1.10.
At run time I get the 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

In fact using

nm -u libgeant321vmc.so

I see that

U _ZN10TVirtualMC14DefineParticleEiPKc15TMCParticleTypeddd

where the U means (from nm man page) that the symbol is undefined.

What is wrong?
It is a problem of geant3_vmc or of ROOT?

The geant3_vmc library has been build just with

gmake

and the environmental variable $ROOTSYS pointing to the ROOT v5.23 directory and $ROOTSYS/lib added to the $LD_LIBRARY_PATH and $ROOTSYS/bin added to $PATH.

Do I have to specify something else when I compile geant3_vmc? Do I have to use some special switch when I compile root?

With regards
Stefano
