Hi, I ran into exactly the same issue with Microsoft Visual Studio 2010. Here is the error I got: u:\development\thirdparty\boost_1_43_0\boost\atomic.hpp(167): warning C4800: 'intptr_t' : forcing value to bool 'true' or 'false' (performance warning) 1>u:\development\thirdparty\boost_1_43_0\boost\atomic\detail\integral-casts.hpp(228): error C2621: member 'boost::detail::atomic::platform_atomic<T>::e' of union 'boost::detail::atomic::platform_atomic<T>::<unnamed-tag>' has copy constructor 1> with 1> [ 1> T=boost::lockfree::tagged_ptr<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node> 1> ] 1> u:\development\thirdparty\boost_1_43_0\boost\atomic\detail\base.hpp(63) : see reference to class template instantiation 'boost::detail::atomic::platform_atomic<T>' being compiled 1> with 1> [ 1> T=boost::lockfree::tagged_ptr<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node> 1> ] 1> u:\development\thirdparty\boost_1_43_0\boost\atomic.hpp(20) : see reference to class template instantiation 'boost::detail::atomic::internal_atomic<T>' being compiled 1> with 1> [ 1> T=boost::lockfree::tagged_ptr<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node> 1> ] 1> u:\development\thirdparty\boost_1_43_0\boost\lockfree\fifo.hpp(202) : see reference to class template instantiation 'boost::atomic<T>' being compiled 1> with 1> [ 1> T=boost::lockfree::tagged_ptr<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node> 1> ] 1> u:\development\thirdparty\boost_1_43_0\boost\lockfree\fifo.hpp(223) : see reference to class template instantiation 'boost::lockfree::detail::fifo<T,freelist_t,Alloc>' being compiled 1> with 1> [ 1> T=int, 1> freelist_t=boost::lockfree::caching_freelist_t, 1> Alloc=std::allocator<int> 1> ] 1> u:\development\thirdparty\concurrencytest\fifotest\fifo.cpp(15) : see reference to class template instantiation 'boost::lockfree::fifo<T>' being compiled 1> with 1> [ 1> T=int 1> ] 1>u:\development\thirdparty\boost_1_43_0\boost\atomic\detail\integral-casts.hpp(228): error C2621: member 'boost::detail::atomic::platform_atomic<T>::e' of union 'boost::detail::atomic::platform_atomic<T>::<unnamed-tag>' has copy constructor 1> with 1> [ 1> T=boost::lockfree::tagged_ptr<boost::lockfree::caching_freelist<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node,std::allocator<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node>>::freelist_node> 1> ] 1> u:\development\thirdparty\boost_1_43_0\boost\atomic\detail\base.hpp(63) : see reference to class template instantiation 'boost::detail::atomic::platform_atomic<T>' being compiled 1> with 1> [ 1> T=boost::lockfree::tagged_ptr<boost::lockfree::caching_freelist<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node,std::allocator<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node>>::freelist_node> 1> ] 1> u:\development\thirdparty\boost_1_43_0\boost\atomic.hpp(20) : see reference to class template instantiation 'boost::detail::atomic::internal_atomic<T>' being compiled 1> with 1> [ 1> T=boost::lockfree::tagged_ptr<boost::lockfree::caching_freelist<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node,std::allocator<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node>>::freelist_node> 1> ] 1> u:\development\thirdparty\boost_1_43_0\boost\lockfree\detail\freelist.hpp(131) : see reference to class template instantiation 'boost::atomic<T>' being compiled 1> with 1> [ 1> T=boost::lockfree::tagged_ptr<boost::lockfree::caching_freelist<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node,std::allocator<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node>>::freelist_node> 1> ] 1> u:\development\thirdparty\boost_1_43_0\boost\lockfree\fifo.hpp(208) : see reference to class template instantiation 'boost::lockfree::caching_freelist<T,Alloc>' being compiled 1> with 1> [ 1> T=boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node, 1> Alloc=std::allocator<boost::lockfree::detail::fifo<int,boost::lockfree::caching_freelist_t,std::allocator<int>>::node> 1> ] 1> 1>Build FAILED. 1> 1>Time Elapsed 00:00:10.46 ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== Have you found a solution yet? -Mike Andrey Zhdanov wrote:

i don't have access to other compilers, so i need to rely on other people's report

Hello Tim,

MSVC 9.0 complains about lockfree/fifo - does not like tagged_ptr to have copy constructor:

Though, after commening copy contructor, there is another error:

1>e:\work\201003\10.lock_free\boost-lf\boost\atomic\detail\integral-casts.hpp(228) : error C2620: member 'boost::detail::atomic::platform_atomic<T>::e' of union 'boost::detail::atomic::platform_atomic<T>::<unnamed-tag>' has user-defined constructor or non-trivial default constructor
