I said something wrong when I said that the compiler tries to use the default constructor. What happens is that it can not match the correct allocator and hence fails to find a valid constructor. Let me link the compiler output to clarify what happens when I use operator[] instead of at(). In bold is the one that should be used but it is deemed not valid: In file included from /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/interprocess/containers/flat_map.hpp:23: In file included from /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/container/flat_map.hpp:29: In file included from /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/container/detail/flat_tree.hpp:30: /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/container/vector.hpp:301:9: error: no matching constructor for initialization of 'boost::interprocess::allocator<int, boost::interprocess::segment_manager<char, boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family, boost::interprocess::offset_ptr<void, long, unsigned long, 0>, 0>, iset_index> >' : Allocator(), m_start(), m_size(), m_capacity() ^ /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/container/vector.hpp:725:9: note: in instantiation of member function 'boost::container::container_detail::vector_alloc_holder<boost::interprocess::allocator<int, boost::interprocess::segment_manager<char, boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family, boost::interprocess::offset_ptr<void, long, unsigned long, 0>, 0>, iset_index> >, boost::container::container_detail::integral_constant<unsigned int, 2> this->priv_subscript) ^ /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/move/detail/move_helpers.hpp:42:14: note: expanded from macro 'BOOST_MOVE_CONVERSION_AWARE_CATCH' { return FWD_FUNCTION(static_cast<const TYPE&>(x)); }\ ^ include/LVCNext/CacheLayout.hxx:191:9: note: in instantiation of member function 'boost::container::flat_map<int, boost::container::vector<int, boost::interprocess::allocator<int, boost::interprocess::segment_manager<char, boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family, boost::interprocess::offset_ptr<void, long, unsigned long, 0>, 0>, iset_index> > >, std::less<int>, boost::interprocess::allocator<std::pair<int, boost::container::vector<int, boost::interprocess::allocator<int, boost::interprocess::segment_manager<char, boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family, boost::interprocess::offset_ptr<void, long, unsigned long, 0>, 0>, iset_index> > > >, boost::interprocess::segment_manager<char, boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family, boost::interprocess::offset_ptr<void, long, unsigned long, 0>, 0>, iset_index> > >::operator[]' requested here sync_policy::edit_data(m_cache_layout)[cache_itr->first][*record_itr] = type_resize_value; ^ /home/user/mbravi/Current/Options/LVCNext/src/cache_layout.cxx:40:6: note: in instantiation of member function 'lvcnext::CacheLayout<InterProcess::MemoryManager<InterProcess::MemoryMappedFileChar, Allocator, DynamicResize>, lvcnext::UnsynchronizedData>::Update' requested here cl.Update(cache_add_fields, cache_remove_fields, resize_list); ^ /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/interprocess/allocators/allocator.hpp:142:4: note: candidate constructor template not viable: requires single argument 'other', but no arguments were provided allocator(const allocator<T2, SegmentManager> &other) ^ /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/interprocess/allocators/allocator.hpp:131:4: note: *candidate constructor not viable: requires single argument 'segment_mngr', but no arguments were provided allocator(segment_manager *segment_mngr)* ^ /home/dev/build/third_party/64-rhel5/boost_1_58_0/include/boost/interprocess/allocators/allocator.hpp:136:4: note: candidate constructor not viable: requires single argument 'other', but no arguments were provided allocator(const allocator &other) ^ 1 error generated. make: *** [obj/64d-rhel6/test-rhel6.1.o] Error 1 -- View this message in context: http://boost.2283326.n4.nabble.com/Interprocess-Container-nested-containers-...
