Dear pandaROOTers,

I have checked out the latest release of pandaRoot from SVN (3227) and I did a make clean and make install. But when I try to run the MVD simulation macro I get the following error message:

Has someone an idea what might have caused this problem?

Hallo Tobias,

the G4OpenGLImmediateXm is part of the G4 visualization which we do not use! and I checked our installation scripts we do not set the flages :
G4VIS_BUILD_OPENGLXM_DRIVER
G4VIS_USE_OPENGLXM

and in the libgeant4vmc.so there is no symbol ZN19G4OpenGLImmediateXmC1Ev at all!

So for me this could be the result of:
1. you configure Geant4 your self!
2. g4libs.C: did you change anything there!
3. you updated the Geant4VMC your self and linked to another G4 installation!

hope this will help you!

regards

Mohammad
