Dear All,
 I am encountering link errors whilst attempting to use the hadronic physics
list (LHEP_PRECO_HP). The procedure I followed is described below (this
procedure is identical to that I was using for geant4.7.0 for which I
encountered no errors) :

cd /usr/local/geant4.7.1/physics_lists/hadronic/Packaging
gmake
cd ../LHEP_PRECO_HP
gmake

this creates static libraries that reside in $G4LIB/plists/$G4SYSTEM

Then I copied GNUmakefile.user.code.example to my directory and commented out
the following lines to set the relevant link variables

EXTRALIBS += -lLHEP_PRECO_HP
EXTRALIBS += -lPackaging

and in my main file I include the header,

#include "LHEP_PRECO_HP.hh"

and declare an instance of the appropriate class:

LHEP_PRECO_HP* physics = new LHEP_PRECO_HP();
runManager->SetUserInitialization(physics);

Then, when I attempt to make the application I encounter a number of errors; the
first being:

/usr/lib/gcc-lib/i586-suse-linux/3.3.5/../../../../i586-suse-linux/bin/ld:
`.gnu.linkonce.t._ZNK23G4NeutronHPInterpolator11InterpolateE21G4InterpolationSchemeddddd'
referenced in section `.rodata' of
/usr/local/geant4.7.1/lib/Linux-g++/libG4had_neu_hp.a(G4NeutronHPVector.o):
defined in discarded section
`.gnu.linkonce.t._ZNK23G4NeutronHPInterpolator11InterpolateE21G4InterpolationSchemeddddd'
of /usr/local/geant4.7.1/lib/Linux-g++/libG4had_neu_hp.a(G4NeutronHPVector.o)

If, on the other hand, I attempt to use LHEP_BIC_HP I encounter the following
linnk error:

/home/iwan/geant4/tmp/Linux-g++/CutsBugTest/exe/CutsBugTest.o(.gnu.linkonce.t._ZN12TLHEP_BIC_HPI21G4VModularPhysicsListEC1Ev+0x254):
In function `TLHEP_BIC_HP<G4VModularPhysicsList>::TLHEP_BIC_HP[in-charge]()':
CutsBugTest.cc: undefined reference to
`HadronPhysicsLHEP_BIC_HP::HadronPhysicsLHEP_BIC_HP[in-charge](G4String const&)'

Note, I did not encounter these problems with geant4.7.0 using the environment:
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
