It seems that my problem with move emulation in projects imported from older MSVC to MSVC10 is that some rvalue references rules need language extensions option activated. Otherwise we can't have movable-only types.
It seems some explicit casts are required, for example in boost/interprocess/detail/move.hpp: template <class T> inline typename remove_reference<T>::type&& move(T&& t) { return t; } Should be either: template <class T> inline typename remove_reference<T>::type&& move(T&& t) { return std::move(t); } or template <class T> inline typename remove_reference<T>::type&& move(T&& t) { return static_cast<typename remove_reference<T>::type&&>(t); } Likewise for the "forward" function. However that still leaves errors deep within the Boost.Preprocessor code: 1> adaptive_node_pool_test.cpp 1>m:\data\boost\trunk\boost\preprocessor\iteration\detail\local.hpp(37): error C2664: 'boost::interprocess::forward' : cannot convert parameter 1 from 'boost::interprocess::segment_manager<CharType,MemoryAlgorithm,IndexType> ' to 'boost::interprocess::segment_manager<CharType,MemoryAlgorithm,IndexType> *&&' 1> with 1> [ 1> CharType=char, 1> MemoryAlgorithm=boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family>, 1> IndexType=boost::interprocess::iset_index 1> ] 1> You cannot bind an lvalue to an rvalue reference 1> m:\data\boost\trunk\libs\interprocess\test\node_pool_test.hpp(146) : see reference to function template instantiation 'T *boost::interprocess::detail::named_proxy<SegmentManager,T,is_iterator>::operator ()<boost::interprocess::segment_manager<CharType,MemoryAlgorithm,IndexType>*>(P0 &&) const' being compiled 1> with 1> [ 1> T=node_pool_t, 1> SegmentManager=boost::interprocess::segment_manager<char,boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family>,boost::interprocess::iset_index>, 1> is_iterator=false, 1> CharType=char, 1> MemoryAlgorithm=boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family>, 1> IndexType=boost::interprocess::iset_index, 1> P0=boost::interprocess::segment_manager<char,boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family>,boost::interprocess::iset_index> * 1> ] 1> m:\data\boost\trunk\libs\interprocess\test\adaptive_node_pool_test.cpp(24) : see reference to function template instantiation 'bool boost::interprocess::test::test_all_node_pool<node_pool_t>(void)' being compiled Which appear to have the same cause, but I'm unable to figure out what needs changing. Seems likely that gcc in C++0x mode has the same issues - creating an rvalue ref needs an explicit cast. HTH, John.
