Hello, I'm using the std::shared_ptr provided with MSVC 2010. I'd like to be able to use boost.serialization to serialize some of those shared_ptrs. I could find an old thread stating that std::tr1::shared_ptr were not handled (and it looked impossible to make them work). Is the situation the same with std::shared_ptr? I thought of the "solution" of using boost::shared_ptr instead of std::shared_ptr, but it is currently not the prefered option: We have parts of our program independant from boost that use std::shared_ptr, we would like those parts to remain independant from boost. And we have other parts of our program where shared_ptr is used without qualification, and where a "using namespace std" directive is active. Switching to boost would incur either qualifying all shared_ptr uses, or adding a "using namespace boost" but that would introduce ambiguities. Thank you for your help! -- Loïc
