Description jaztango 2005-10-18 16:23:01 CEST

I am trying to compile this example and get errors of the following type:

Linking G4PersEx01 ...
/geant/geant4.7.1/examples/extended/persistency/rootio//tmp/Linux-g++/G4PersEx01/G4PersEx01.o(.text+0x19):

Any ideas?

If you strictly follow the instructions in
  examples/extended/persistency/PersEx01/README
you should be able to build the example with no troubles.
It seems to me that your problem is due to a wrong setup for the visualization
drivers. Did you build the Geant4 libraries using any of the graphics drivers ?
If so, you should have set in your environment the corresponding G4VIS_BUILD_xxx
variables when building the libraries and corresponding G4VIS_USE_xxxx when
building your examples.
Another possibility is that you're linking against incompatible libraries (i.e.
libraries built in another system different from yours).
I would suggest to verify your setup by building first a simpler example, like
those distributed in the examples/novice directory.
