Hi all,

I'm having issues compiling  boost::unordered_map with boost::interprocess. I'm using boost 1.57 and compiler is GCC 4.1.2 . I've tried to ask it on SO few months ago, but got no solution for it and decided to use just map. Now I'm seeking for some performance improvement again, so I will try my luck here.
I took code from the answer on SO (http://stackoverflow.com/questions/29557680/boost-interprocess-unordered-map-compilation) with minimal changes to make it work under non C++11 compiler. It looks better than my and there are same errors generated.

Code:

#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/containers/string.hpp>
#include <boost/interprocess/containers/map.hpp>
#include <boost/unordered_map.hpp>

namespace bip = boost::interprocess;
// ShmString is boost::interprocess::basic_string
typedef bip::allocator<char, bip::managed_shared_memory::segment_manager> CharAllocator;
typedef bip::basic_string<char, std::char_traits<char>, CharAllocator> ShmString;
typedef ShmString HashKeyType;
// ComplexType is a wrapper for internal interprocess::map
struct ComplexType {
    typedef bip::allocator<std::pair<int const, int>, bip::managed_shared_memory::segment_manager> Alloc;
    typedef bip::map<int, int, std::less<int>, Alloc> Map;

    template <typename Alloc2>
    ComplexType(std::string, Alloc2 const& alloc) : map(alloc) {}
    Map map;
};

typedef ComplexType HashMappedType;
typedef std::pair<const ShmString, ComplexType> HashValueType;
typedef bip::allocator<HashValueType, bip::managed_shared_memory::segment_manager> HashMemAllocator;
typedef boost::unordered_map<HashKeyType, HashMappedType, boost::hash<HashKeyType>, std::equal_to<HashKeyType>, HashMemAllocator>
    TestHashMap;

int main()
{
    // Allocation:
    {
        bip::managed_shared_memory segment(bip::open_or_create, "MySharedMemory", 65536);
        TestHashMap  * thm_ = segment.construct<TestHashMap>("TestHashMap")(3, boost::hash<ShmString>(), std::equal_to<ShmString>(),
                segment.get_allocator<HashValueType>());

    }
    // Usage:
    bip::managed_shared_memory segment(bip::open_only, "MySharedMemory");
    TestHashMap * thm_ = segment.construct<TestHashMap>("TestHashMap")(3, boost::hash<ShmString>(), std::equal_to<ShmString>(), segment.get_allocator<HashValueType>());
    ShmString str("123.345", segment.get_allocator<ShmString>());

    ComplexType th("MySharedMemory", segment.get_segment_manager());

    HashValueType value(str, th);
    thm_->insert(value);
}

And here is some error output:

Is it possible to fix this problem without switching  updating the compiler?

Thanks and regards.
