Hi Marcus,
some weeks back you opened ticket #200 with a patch to make boost::bind
work with OpenSG. The ticket says this is for 1.8, is that correct?
Do you have some more information on why that patch is necessary, I've
looked over the documentation of boost::bind and could not find any
mention of the need to provide a get_pointer function.
Anyway the attached test compiles, if get_pointer overloads for
FCPtr<FCPtrType, FCType> and NodePtr are added, but it crashes at
runtime in FieldContainerPtrBase::operator =.
Do you have a small example that shows how to use boost::bind correctly?
Thanks,
Carsten
