I am posting this again in that the boot list indicated it needed subscription. ------- Jonathan, (redi at gcc dot gnu.org <gcc-bugzilla@gcc.gnu.org>) Re: [Bug c++/53899] [C++0x] undefined reference to std::atomic<boost::lockfree::detail::tagged_ptr...

Tim Blechmann posted on the Boost list this morning he was doing final testing for the Boost 51 release. I will copy this to him in case he has an idea. My impression is that g++ -std=c++0x and boost lockfree are rather close. Neil -- View this message in context: http://boost.2283326.n4.nabble.com/lockfree-include-into-1-51-tp4632704p4632...
