I have a derived class that exports its type and overrides get_key for
serialization through a base class pointer. If I move the definition of the
overridden get_key function out of the header into a cpp file, an assertion
fails on line 49 of extended_type_info.cpp.
Take a look at the example "test_no_rtti".
the class polymorphic_derived has a get_key
declaration - but the get_key definition is not
inline. This would seem identical your case.
You might want to make a small variation of
test_no_rtti such that the definition of
polymorphic_derived1::get_key defintion is moved
to a separate source and verify that
it builds and runs correctly.
If I define any other functions in the cpp file, I get a linker error
saying that the get_key symbol is already defined. It looks to me that any
serializable derived class must be completely defined in the header file. Is
this correct?
If so, why does such a limitation exist?
I don't think this limitation exists
Thank you
Robert Ramey
