boost multi_index_container not compiling - c++

Question

Trying to follow the boost docs on the usage of this, but am running into a snag.
Building on CentOS 7, g++ 4.8.5-28. Language standard: C++03
Working sample: https://godbolt.org/z/KPvjS_
My Code:
#include <boost/multi_index_container.hpp>
#include <boost/multi_index/sequenced_index.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/identity.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/multi_index/composite_key.hpp>
using namespace ::boost;

typedef unsigned char UInt8;
typedef unsigned int UInt32;
typedef UInt8 ACCESSID[16];
class AccessID
{
public:
AccessID();
AccessID(const AccessID & id);
const std::size_t GetHash() const { return hashId;}
private:
ACCESSID id;
std::size_t hashId;
};
struct map_entry
{
UInt32 subject_hash;
UInt32 container;
AccessID clientAccessId;
AccessID serverAccessId;
map_entry( UInt32 parmHash
, UInt32 parmContainer

, AccessID &parmServerAccessId )
: subject_hash( parmHash )
, container( parmContainer )
, clientAccessId( parmClientAccessId )
, serverAccessId( parmServerAccessId )
{
}
};
struct clientAccessId_extractor
{
typedef std::size_t result_type;
result_type operator ()( const map_entry &e ) const
{
// Hash is a boost::hash value.
return e.clientAccessId.GetHash();
}
};
struct serverAccessId_extractor
{
typedef std::size_t result_type;

{
return e.serverAccessId.GetHash();
}
};
// Define the mapping relationships; like a "database" of sorts.

// Define an object of the mapping db type.
mapDb_t mapDb;
public:

~MappingClass() { };
};
And the error output from trying to compile:

I don't really understand what the boost errors are, here. What have I missed?

Answer 1

The map index types are not default constructible, you need to change them to references and initialise them in your constructor:
class MappingClass
{
private:
// Define an object of the mapping db type.
mapDb_t mapDb;
// Index iterators.
mapDb_by_clientAid::iterator clientIter;
mapDb_by_serverAid::iterator serverIter;
// Index views.
mapDb_by_serverAid& serverView;
mapDb_by_clientAid& clientView;
public:
MappingClass()
:serverView( mapDb.get< 0 >() ),
clientView( mapDb.get< 1 >() ) { };
~MappingClass() { };
};
Note you also need to move mapDb to before the views so that it is initialised first.
