I'm trying to do what you suggest, with some additional parameters:

----

#include <boost/python/module.hpp>
#include <boost/python/class.hpp>
#include <boost/python/def.hpp>

#include <memory>

namespace python = boost::python;

namespace
{

class Bar {};

}

BOOST_PYTHON_MODULE(pfe)
{
    python::class_<Bar,
                   std::auto_ptr<Bar>,
                   boost::noncopyable> bar("Bar", python::no_init);

}

----

I copied that over 'getting_started2.cc and run
bjam "-sBUILD=<architecture>mips4" (with TOOLS=mipspro).

This results in the error message

cc-1306 CC: ERROR File = 
/homes/Developer/sseefel/boost/boost/python/object/make_instance.hpp, 
Line = 60
   Class "std::auto_ptr<<unnamed>::Bar>" has no copy constructor to copy 
a const
           object.

           return new ((void*)&result->storage) Holder(x);

...

what is wrong ? I guess it's either boost:noncopyable or python::no_init
though I don't see why that should be wrong.

Thanks,
