[Swig-user] Help with template specialization: Import Error symbol not found

[Jeremy C. <jer...@gm...>]

I have a class that looks like:
template<typename S>
class M{
    ...

    S*   M_method(S* const sr, int N);

    ...
};

When I define the templated function M_Method everything works fine.  The
problem arises when I try to do template specialization for M_method(...); I
need slightly different methods for typename H vs. typename B.  Both H and B
inherit from the virtual base class F.  When I have specialization, I get an
ImportError, it couldn't find the symbol "vtable for H".

In my SWIG interface file I have:

%template(M_B) M<B>;
%template(M_H) M<H>;

but that doesn't seem to make any difference.  Everything in the
documentation seemed to say that template specialization "just works".  Is
there something special I need to put in my SWIG interface file in order to
use template specialization?

Thanks,
Jeremy
