Right, you'd better talk with them. Boost.Python allows to export
libraries without touching them, but sometimes a small library change
could make you task easier.

The following code works:

#include <vector>

struct item_t{

    explicit item_t( int v)
    : value( v )

    int value;


    item_t& operator=( const item_t& other );


int main( int argc, const char** argv ){
    std::vector< item_t > values( 10, item_t( 12 ));
    for( size_t i = 0; i < values.size(); ++i ){
        values[ i ].value = i;
