Hello
This is my last problem with the BSL but the most important one (because
there is no workaround).
I am trying to serialize a class (whose name is "ClassSpecification") which
has a std::vector of pointers. The code for serializing the class the
pointer refer to (MemberVariableSpecification) is written and instantiated
correctly. However I cannot correctly serialize the std::vector. It fails
with a message complaining about:
C:/Boost/include/boost-1_33_1/boost/archive/detail/iserializer.hpp:115:
error: incomplete type
`boost::serialization::extended_type_info_null<std::vector<MemberVariableSpecification*,
std::allocator<MemberVariableSpecification*> > >' used in nested name
specifier
I do not understand why I need an extended_type_info for this vector. I sure
need it for the class the pointers refer to (and I did specify it), but the
std::vector itself is serialized as such, not as a pointer.
*** hmmm - can sympathise with you here. I suspect that this is a mistake.
It might
be an accidental side effect of the fact that the default serialization
trait for any class is tracked with
class information. You might try the following:
BOOST_CLASS_IMPLEMENTATION(
std::vector<MemberVariableSpecification*,
std::allocator<MemberVariableSpecification*>,
boost::serialization::object_serializable
)
Why do I get this error ???
I would have to look into it.
Can you please check the attached code and help me?
Thanks
Jean-Noël
Ps: using gcc 3.4.2
