My application that works with 1.32 is failing to link with 1.33 RC1 due
to boost::serialization::void_cast_register (specialised for my classes)
being an unresolved external.
In my case the void_cast_register call and the BOOST_CLASS_EXPORT macro
are in one module while the serialization is done in another module,
with all modules linked in one application.
The code below also shows this problem, however if I add an archive
class and header to the example then it will compile and link ok.
Obviously this is when serialization is in the same module as the
void_cast_register call.
Any suggestions about what I need to add to make the application link?
