Ticket #6648 (new Bugs)

Opened 2 years ago

managed_unique_ptr cannot be used inside template (VS2008).

Reported by: anonymous Owned by: igaztanaga
Milestone: To Be Determined Component: interprocess
Version: Boost 1.49.0 Severity: Problem
Keywords: Cc:

Description

There is a very simple example:

#include <iostream>

#include <boost/interprocess/managed_windows_shared_memory.hpp>

#include <boost/interprocess/smart_ptr/unique_ptr.hpp>
#include <boost/interprocess/allocators/allocator.hpp>
#include <boost/interprocess/containers/list.hpp>
#include <boost/interprocess/sync/named_mutex.hpp>
#include <boost/interprocess/sync/named_condition.hpp>
#include <boost/interprocess/sync/scoped_lock.hpp>

struct Request
{
 int a;
};

template<typename Segment, typename T>
class Channel
{
public:

 /// Value pointer in queue.
 typedef typename boost::interprocess::managed_unique_ptr<T, Segment>::type
  ValuePtr;

};

int main(int argc, char* argv[])
{
 Channel<boost::interprocess::managed_windows_shared_memory, Request>::ValuePtr v;
 
 std::cout << "Test" << std::endl;
 
 return 0;
}

I got this error in Visual Studio 2008:

................

This example works fine in boost 1.48.0
