Hello,
I am using boost 1.44 and trying to create shared memory and utilizing the segment manager with a interprocess map.
I continually get a compile error when call the segment manager construct call.  I can't figure out what the problem is.
I have tried copy/paste example but continue to get the same error.

"/usr/local/boost_1_44_0/boost/interprocess/detail/named_proxy.hpp:123:131: error: no matching function for call to 'forward(std::less<int>()&)'

Below is the snippet of  code:

       string driver_share = _cc.share_name + "_drivers";

       using namespace boost::interprocess;
       //Clean up before creating shared memory
       shared_memory_object::remove(driver_share.c_str());

       managed_shared_memory segment(create_only, driver_share.c_str(),65536);

       typedef boost::process::pid_type key_type;
       typedef boost::posix_time::ptime value_type;
       typedef std::pair<key_type, value_type> pair_type;

       typedef boost::interprocess::allocator<pair_type, managed_shared_memory::segment_manager> mem_allocator;

       typedef boost::interprocess::map<key_type, value_type, std::less<key_type>, mem_allocator> driver_map;

       const mem_allocator alloc_instance(segment.get_segment_manager());

       driver_map *dmap = segment.construct<driver_map>("DriverMap")(
                     std::less<int>(),
                     alloc_instance);

My include files are as follows:

#include <boost/thread/thread.hpp>
#include <boost/date_time/posix_time/posix_time_types.hpp>
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/process/all.hpp>
#include <boost/interprocess/allocators/allocator.hpp>
#include <boost/interprocess/containers/map.hpp>
#include <map>
#include <functional>
#include <iostream>
using namespace boost;
using namespace boost::posix_time;
using namespace std;

IF you know of any reason why I get this error that would be great.........I will continue to read the boost documentation.

Regards
carla
