[Boost-users] Boost.Signals2 - tracking an object managed with tr1::shared_ptr

Is it possible to use slot::track with a tr1::shared_ptr instead of a boost::shared_ptr? For example: std::tr1::shared_ptr<MyObject> o; typedef boost::signals2::signal SigType; SigType s; // Error: can't convert std::tr1::shared_ptr<MyObject> to boost::weak_ptr... s.connect(SigType::slot_type(&MyObject::function, o.get()).track(o)); According to the docs you HAVE to use boost::shared_ptr. I'm just hoping there's some traits specialization or something I can provide so that I can get away with using the tr1 version instead (all our code is already written with tr1). Thanks! -Nathan
