I tried to compile this boost dependent class with VS2008 and VS2010 (error lines are in bold)

#include <boost/interprocess/ipc/message_queue.hpp>

#include <boost/interprocess/sync/scoped_lock.hpp>

#include <boost/interprocess/sync/named_mutex.hpp> 

#include <boost/interprocess/sync/named_condition.hpp>

struct SafeShardQueue

{

typedef boost::interprocess::scoped_lock<boost::interprocess::named_mutex> scoped_mutex;

SafeShardQueue()//:

{

}

~SafeShardQueue()

{

remove();

}

void wait_msg()

{

scoped_mutex locker(*mu);

data_avail_condition->wait(locker);

}

void wait_space()

{

scoped_mutex locker(*mu);

queue_empty_condition->wait(locker);

}

boost::shared_ptr<boost::interprocess::message_queue> msgs;

boost::shared_ptr<boost::interprocess::named_condition> data_avail_condition;

boost::shared_ptr<boost::interprocess::named_mutex> mu;

boost::shared_ptr<boost::interprocess::named_condition> queue_empty_condition;

static SafeShardQueue* open()

{

SafeShardQueue* tmp = new SafeShardQueue();

boost::interprocess::open_only_t open_create_type;

tmp->msgs.reset(new boost::interprocess::message_queue  (open_create_type, "message_queue"));

tmp->mu.reset(new boost::interprocess::named_mutex(open_create_type, "shared_queue_mutex"));

tmp->data_avail_condition .reset(new boost::interprocess::named_condition(open_create_type, "data_avail_condition"));

tmp->queue_empty_condition .reset(new boost::interprocess::named_condition(open_create_type, "queue_empty_condition"));

return tmp;

}

static SafeShardQueue* create()

{

remove();

SafeShardQueue* tmp = new SafeShardQueue();

boost::interprocess::create_only_t open_create_type;

std::stringstream ss;

try

{

tmp->msgs.reset(new boost::interprocess::message_queue(open_create_type, "message_queue", 256, 1024));

tmp->mu.reset(new boost::interprocess::named_mutex(open_create_type, "shared_queue_mutex"));

tmp->data_avail_condition .reset(new boost::interprocess::named_condition(open_create_type, "data_avail_condition"));

tmp->queue_empty_condition .reset(new boost::interprocess::named_condition(open_create_type, "queue_empty_condition"));

}

catch (const boost::interprocess::interprocess_exception& e)

{

ss << e.what();

}

return tmp;

}

static void remove()

{

boost::interprocess::message_queue::remove("message_queue");

boost::interprocess::named_mutex::remove("shared_queue_mutex");

boost::interprocess::named_condition::remove("data_avail_condition");

boost::interprocess::named_condition::remove("queue_empty_condition");

}

};

I got the following error message:

It seems that you cannot use both interprocess::message_queue and interprocess:named_condition in the same class.

Any ideas? I would greatly appreciate your help in this issue.
