Hmm, my errors are getting weirder and weirder:

35    FATAL yade.Omega /home/chiab/yadeNew/Branch6/core/Omega.cpp:226 loadPlugins: /home/chiab/yadeNew/YADEb6/lib/yade-b6/extra/libCWBoonPlugin3.so: undefined symbol `typeinfo for InteractionGeometryFunctor'
36    FATAL yade.Omega /home/chiab/yadeNew/Branch6/core/Omega.cpp:226 loadPlugins: /home/chiab/yadeNew/YADEb6/lib/yade-b6/extra/libCWBoonPlugin3.so: /home/chiab/yadeNew/YADEb6/lib/yade-b6/extra/libCWBoonPlugin3.so: undefined symbol: _ZTI26InteractionGeometryFunctor
36    FATAL yade.Omega /home/chiab/yadeNew/Branch6/core/Omega.cpp:226 loadPlugins: Bailing out.

Do you know what's happening?


Yours,

Boon
