6147	message_queue sample fails to compile in 32-bit	Graham Perks <graham@…>	Ion Gaztañaga	"Just upgraded to 1.48.

On OS X I compile the sample program with: gcc -I <blah path to boost>/include -arch i386  main.cpp

and it fails with ""....boost/interprocess/ipc/message_queue.hpp:330: error: no matching function for call to ‘get_rounded_size(long unsigned int, const unsigned int&)’""

It's the MQ creation line that fails. If I build for x64, it compiles successfully. The source is:

#define BOOST_DATE_TIME_NO_LIB
#include <boost/interprocess/ipc/message_queue.hpp>
#include <iostream>
#include <vector>

using namespace boost::interprocess;

int main ()
{
    try{
        //Erase previous message queue
        message_queue::remove(""message_queue"");
        
        //Create a message_queue.
        message_queue mq
        (create_only               //only create
         ,""message_queue""           //name
         ,100                       //max message number
         ,sizeof(int)               //max message size
         );
        
        //Send 100 numbers
        for(int i = 0; i < 100; ++i){
            mq.send(&i, sizeof(i), 0);
        }
    }
    catch(interprocess_exception &ex){
        std::cout << ex.what() << std::endl;
        return 1;
    }
    
    return 0;
