1. you cannot export variable, without exporting its type first: you have to
expose s_address class too, if you want to expose address mem. variable.

2. here is the code that was generated by Py++(
http://language-binding.net/), the only change I did for original code
was to change everything to
public.

#include "boost/python.hpp"

#include "1.hpp"

namespace bp = boost::python;

BOOST_PYTHON_MODULE(pyplusplus){
    { //::Customers
        typedef bp::class_< Customers > Customers_exposer_t;
        Customers_exposer_t Customers_exposer = Customers_exposer_t(
"Customers" );
        bp::scope Customers_scope( Customers_exposer );
        bp::class_< Customers::s_address >( "s_address" )
            .def_readwrite( "city", &Customers::s_address::city )
            .def_readwrite( "contact", &Customers::s_address::contact )
            .def_readwrite( "country", &Customers::s_address::country )
            .def_readwrite( "postalCode", &Customers::s_address::postalCode
)
            .def_readwrite( "province", &Customers::s_address::province )

            .def_readwrite( "street1", &Customers::s_address::street1 )
            .def_readwrite( "street2", &Customers::s_address::street2 );
        Customers_exposer.def( bp::init< >() );
        Customers_exposer.def_readonly( "address", &Customers::address );
    }
}
