python - vector of user defined types

From: John Hunter (jdhunter_at_[hidden])

Yet another boost::python question...

I am writing a template based boost::python class generator for
std::vector<T>.  I noticed how David did it for vector<float> in
comprehensive.cpp and tried to generalize it because I have lots of
member functions that return vector<T> for user defined types.

The technique works great for built in types, but fails for my user
defined class 'Date'.  

I use the VectorPy template class (below) to generate python
extensions like so:

    boost::python::module_builder m("MyModule");
    DatePy date( m );
    VectorPy<float> vf( m, "VectorFloats" );
    VectorPy<int> vi( m, "VectorInts" );
    VectorPy<Date> vd( m, "VectorDates" );

where the VectorPy code and the horribly long compiler message appear
below (all of the compiler errors are generated by the template
instantiation 'template class VectorPy<DateFinancial>;' which is the
last line of VectorPy.cpp.

The only thing in the docs that I have found about potential problems
with user defined types is

   Because the to_python and from_python functions for a user-defined
   class are defined by extension_class<T>, it is important that an
   instantiation of extension_class<T> is visible to any code which
   wraps a C++ function with a T, T*, const T&, etc. parameter or
   return value. In particular, you may want to create all of the
   classes at the top of your module's init function, then def the
   member functions later to avoid problems with inter-class
   dependencies.

Is this related to my problem?  I certainly include the header for the
'Date' class before the module init function and VectorPy<Date>
instantiation.  Any suggestions for a workaround?

Thanks,
John Hunter
