hello to boost multi index - c++

Question

I have started working on a project that incorporates some of boost libraries(thread and MPI).
I am going to use boost multi_index in one of the modules which is not using boost at all.FYI this project has not used boost multi index before)
as soon as I tried to include
boost/multi_index_container.hpp
to the file and built the projects, I received a number of errors starting with the following:
Building CXX object CMakeFiles/SimMobility.dir/main.cpp.o

/usr/include/boost/multi_index/detail/header_holder.hpp:35:32: error: expected primary-expression before ‘)’ token
may I know what the problem is? is it cmake not finding what it needs? any idea how to solve it?
Edit:
in case you want to have a look at the source code, here is a simplified version:
RoadNetwork.hpp:
#pragma once
#include <iostream>
#include <vector>
#include <set>
#include <boost/multi_index_container.hpp> //causing problem!!!!!!!
namespace geo {class Links_pimpl;}
namespace sim_mob
{
//Forward declarations
class Node;
class UniNode;
class MultiNode;
class Point2D;
class Link;
namespace aimsun
{
//Forward declaration
class Loader;
}
//typedef multi_index_container<
//sim_mob::Link,
// indexed_by<
// random_access<>,
//// ordered_unique< member<sim_mob::Link, std::string, &sim_mob::Link::linkID> >
// >
//> Link_m;
class RoadNetwork {
public:
RoadNetwork() { drivingSide=DRIVES_ON_LEFT; } //TEMP
sim_mob::Node* locateNode(const sim_mob::Point2D& position, bool includeUniNodes=false, int maxDistCM=100) const;
private:
std::vector<sim_mob::MultiNode*> nodes;
std::vector<sim_mob::Link*> links;
std::vector<sim_mob::MultiNode*>& getNodesRW() { return nodes; }
std::set<sim_mob::UniNode*>& getUniNodesRW() { return segmentnodes; }
std::vector<sim_mob::Link*>& getLinksRW() { return links; }
friend class sim_mob::aimsun::Loader;
friend class geo::Links_pimpl;
};
}
Thank you your kind help

I modified your header to look like this:
#pragma once
#include <iostream>
#include <vector>
#include <set>
#include <boost/multi_index_container.hpp> //causing problem!!!!!!!
using boost::multi_index_container;
namespace geo {class Links_pimpl;}
namespace sim_mob
{
//Forward declarations
class Node;
class UniNode;
class MultiNode;
class Point2D;
class Link;
namespace aimsun
{
//Forward declaration
class Loader;
}
//typedef multi_index_container<
//sim_mob::Link,
// indexed_by<
// random_access<>,
// ordered_unique< member<sim_mob::Link, std::string, &sim_mob::Link::linkID> >
// >
//> Link_m;
class RoadNetwork {
int drivingSide;
enum side { DRIVES_ON_LEFT, DRIVES_ON_RIGHT};
public:
RoadNetwork() { drivingSide=DRIVES_ON_LEFT; } //TEMP
sim_mob::Node* locateNode(const sim_mob::Point2D& position, bool includeUniNodes=false, int maxDistCM=100) const;
private:
std::vector<sim_mob::MultiNode*> nodes;
std::vector<sim_mob::Link*> links;
std::set<sim_mob::UniNode*> segmentnodes;
std::vector<sim_mob::MultiNode*>& getNodesRW() { return nodes; }
std::set<sim_mob::UniNode*>& getUniNodesRW() { return segmentnodes; }
std::vector<sim_mob::Link*>& getLinksRW() { return links; }
friend class sim_mob::aimsun::Loader;
friend class geo::Links_pimpl;
};
}
Then I included it in a small file that instantiated a RoadNetwork object:
#include <iostream>
#include "roadnetwork.hpp"
int main() {
sim_mob::RoadNetwork roads;
return 0;
}
This compiled, linked, and executed (though produced no output).
Not entirely sure what problem you're encountering...

Answer 2

I encountered the same problem and tracked it down. Do you have by chance a #define final somewhere in your sources before including boost/multi_index.hpp or a -Dfinal in your compiler settings? In my case that was the problem, I use the C++11 keywords final and override in my classes and had to define them when using older compilers.
Or, maybe it's some other identifier used by multi_index that you have defined somewhere. You could dump all your defined macros as described here and check if disabling one of them helps.

Answer 3

I also encountered similar problem.
I got compile error in
multi_index header_holder file.
warning : final key word is blah... blah...
So I changed the
#include <boost/xxxxx>
position to other place.
( ex: stdafx.h etc ... )
Try this one.
