Hi, I eagerly want to try boost 1.49, but the compiler error stuck me. managed_unique_ptr cannot be used inside template if I use Visual Studio 2008: There is a very simple example: #include <iostream> #include <boost/interprocess/managed_windows_shared_memory.hpp> #include <boost/interprocess/smart_ptr/unique_ptr.hpp> #include <boost/interprocess/allocators/allocator.hpp> #include <boost/interprocess/containers/list.hpp> #include <boost/interprocess/sync/named_mutex.hpp> #include <boost/interprocess/sync/named_condition.hpp> #include <boost/interprocess/sync/scoped_lock.hpp> struct Request { int a; }; template<typename Segment, typename T> class Channel { public: /// Value pointer in queue. typedef typename boost::interprocess::managed_unique_ptr<T, Segment>::type ValuePtr; }; int main(int argc, char* argv[]) { Channel<boost::interprocess::managed_windows_shared_memory, Request>::ValuePtr v; std::cout << "Test" << std::endl; return 0; } I got this error in Visual Studio 2008: T.cpp C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/pointer_type.hpp(64) : error C2039: 'remove_reference' : is not a member of 'boost::interprocess::ipcdetail::ipcdetail' C:\Program Files\boost\boost_1_49_0\boost/interprocess/smart_ptr/unique_ptr.hpp(94) : see reference to class template instantiation 'boost::interprocess::ipcdetail::pointer_type<T,D>' being compiled with [ T=Request, D=boost::interprocess::deleter<Request,boost::interprocess::segment_manager<char,boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family>,boost::interprocess::iset_index>> ] T.cpp(34) : see reference to class template instantiation 'boost::interprocess::unique_ptr<T,D>' being compiled with [ T=Request, D=boost::interprocess::deleter<Request,boost::interprocess::segment_manager<char,boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family>,boost::interprocess::iset_index>> ] C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/pointer_type.hpp(64) : error C2947: expecting '>' to terminate template-argument-list, found '<' C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/pointer_type.hpp(64) : error C3203: 'remove_reference' : unspecialized class template can't be used as a template argument for template parameter 'D', expected a real type C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/pointer_type.hpp(64) : error C2955: 'boost::interprocess::ipcdetail::remove_reference' : use of class template requires template argument list C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/type_traits.hpp(30) : see declaration of 'boost::interprocess::ipcdetail::remove_reference' C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/pointer_type.hpp(64) : error C2143: syntax error : missing ';' before '>' C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/pointer_type.hpp(64) : error C2039: 'type' : is not a member of '`global namespace'' C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/pointer_type.hpp(64) : error C2039: 'type' : is not a member of '`global namespace'' C:\Program Files\boost\boost_1_49_0\boost/interprocess/detail/pointer_type.hpp(64) : error C2238: unexpected token(s) preceding ';' C:\Program Files\boost\boost_1_49_0\boost/interprocess/smart_ptr/unique_ptr.hpp(94) : error C2039: 'type' : is not a member of 'boost::interprocess::ipcdetail::pointer_type<T,D>' ................ This example works fine in boost 1.48.0 I submit a ticket ( https://svn.boost.org/trac/boost/ticket/6648 #6648 ) to boost::interprocess, but no any reply since 3 weeks ago, So I just ask how to solve this problem or any direction? Thanks. -- View this message in context: http://boost.2283326.n4.nabble.com/boost-interprocess-managed-unique-ptr-can... Sent from the Boost - Users mailing list archive at Nabble.com.
