That solution is really impractical, IMHO.
If this is really the only solution, I would consider the serialization lib
broken wrt to DLLs, and that should be in the docs somewhere.
That's really too bad, since it is such a nice and useful library!
I.e. how would you solve the following, if A and B are unrelated libraries
in seperate DLLs sharing a class X that is serialized as part of serializing
A and B?
//dll A
struct A
{
X x;
};
//dll B
struct B
{
X x;
};
Placing the serialization code for both libraries in a third io.dll means
that any program using just one of A or B becomes dependent on both A and B
(since io.dll must link to both A and B). And if you added a struct C { X
x; }; it would be even worse..

Ensure that the serialization code is in one DLL by having some function
like:
MyClass *
deserializeMyClass(std::istream & is);
And call that from either dll. Then all the serialization magic is hidden
(and instantiated) in one dll and you don't need to worry about cross-dll
template/static/ARGH!
HTH and good luck!

Subject: [Boost-users] [serialization] DLL woes
Hi,
I'm trying to serialize a class using two functions located in different
DLLs.
I can serialize fine by calling one function, but when I call the second it
triggers
an assertion in extended_type_info.cpp:
// make sure that attempt at registration is done only once
assert(lookup(eti) == m_self->m_map.end());
Apparently the class is registered twice, but how do I avoid that?
