The macro BOOST_NO_RVALUE_REFERENCES is not defined, which means boost thinks the compiler supports rvalue references. Since the code is header only, how Boost was built is irrelevant - but there must be some mismatch between what Boost.Config is doing and what type_traits expects. The only thing I can think of that would cause that are either: * A really really old version of Boost.Config with a newer version of type_traits - not sure how you would manage that though, or... * You have a custom config (in boost/config/user.hpp) which is setup for a newer MSVC version. If all else fails, try with a fresh boost source tree, HTH, John. ------------------------------------------------------- Thank you very much John. I didn't changed anything of the boost installation whatsoever, except for the build itself, before that problem.I was using exactly the same thing as I did 2 yearly ago, when it worked. Now it works, for boost 1.39.0, 1.49.0 and 1.57.0. But I cannot think of anything that I did made the difference.

I'm compiling a old project which used to work fine. But now I received a bunch of errors (this is not a surprise because the project have a lot of other dependencies and I'm in the way of setting them up) with the first one as: c:\lib\boost_1_49_0\boost\type_traits\add_lvalue_reference.hpp(19) : error C2143: syntax error : missing ',' before '&&' I'm using Win 7 SP1 + VS 2008 with SP + boost 1.49.0 (I'm using this because I previous used this. If this works fine, I will consider migrating to the latest version) Thanks for any hints. If you are using an older version of Boost and it was working before and now it is not working, something must have changed. Try to determine what might have changed. You also need to show source code you are compiling when the error occurs. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users -- Juan :wq _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
