Hi all, I am getting following error in boost multi-index library. I am using following code to add and remove procedures by id in multi index container. Can somebody please let me know what might be wrong here? Really appreciate your quick response on this. // HEADER FILE #include #include #include #include #include #include #include #include #include "Procedure.h" using boost::multi_index_container; using namespace boost::multi_index; /** * Defines tag used for procedure id. */ struct procedure_id_tag { }; class Procedure_Pool: boost::noncopyable { private: /** * Type definition for multi index container. */ typedef multi_index_container< Procedure*, indexed_by< hashed_unique< tag, const_mem_fun >
