This are the warnings I'm getting while compiling a bigger project with the currect boost trunk version: boost/lexical_cast.hpp(726): warning C4512: 'boost::detail::lcast_put_unsigned' : assignment operator could not be generated boost/lexical_cast.hpp(862): warning C4512: 'boost::detail::lcast_ret_unsigned' : assignment operator could not be generated boost/lexical_cast.hpp(1984): warning C4512: 'boost::detail::lexical_ostream_limited_src>' : assignment operator could not be generated This classes (and possibly more) should have a deleted/private assignment operator or disable this warning altogether. Hopefully this can be fixed before the 1.55 release." Bugs closed Boost 1.56.0 lexical_cast Boost Development Trunk Problem fixed
