[Boost-users] cannot compile boost pmr small_vector snippet

Hi there, I am trying to use the pmr version of the boost small_vector container. I expected the following to work: #include #include boost::container::pmr::polymorphic_allocator<int> alloc; boost::container::pmr::small_vector vec(alloc); But this does not compile with boost 65, gcc 7.3/clang 6.0. The compile error seems to suggest I should be using small_vector_allocator which is an internal class. The exact clang error is below. Am I missing something here? Thanks /usr/include/boost/container/small_vector.hpp:514:41: note: candidate constructor not viable: no known conversion from 'boost::container::pmr::polymorphic_allocator<int>' to 'const boost::container::small_vector::allocator_type' (aka 'const small_vector_allocator

') for 1st argument BOOST_CONTAINER_FORCEINLINE explicit small_vector(const allocator_type &a)
