Hello,

I've just been checking and could not find any "using namespace std"
statement in any of the includes...

I've even been checking with reverting to genuine composite_key file and
adding an explicit

namespace boost
{
}
using namespace boost;

before the includes in my cpp file which appear in the following order :

#include <boost/multi_index_container.hpp>
#include <boost/multi_index/tag.hpp>
#include <boost/multi_index/indexed_by.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/multi_index/composite_key.hpp>

Adding this directive do not solve the issue...

Regards,

Mathieu Peyréga
