Boost C++ Libraries: Ticket #6147: message_queue sample fails to compile in 32-bit

Fri, 18 Nov 2011 19:42:20 GMT

Retry code formatting. It's the sample from the boost docs.

#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;
}

If anyone has a workaround for this, it would be much appreciated.

I was able to workaround this by adding this code before including the boost headers. It adds a second type to the get_rounded_size template.

namespace boost {
    namespace interprocess {
        namespace ipcdetail {
            //Rounds "orig_size" by excess to round_to bytes
            template<class SizeType, class ST2>
            inline SizeType get_rounded_size(SizeType orig_size, ST2 round_to)
            {
                return ((orig_size-1)/round_to+1)*round_to;
            }
        }
    }
}

Fixed in trunk and release branches adding

#include <boost/interprocess/detail/utilities.hpp>

to message queue header.

Still not fixed in i386 GCC 4.2 xcode 3.2.6 (only works in x86_64) even with this

#include <boost/interprocess/detail/utilities.hpp>

inclusion in message_queue.hpp in boost 1.50 (macports) (with Mac OS X 10.6 SDK / deployment target 10.5).

Graham Perks's workaround allows compiling.

I successfully compiled your test using trunk code in Mac OS 10.6.2 with GCC:

i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664)

can you check the bug is fixed?

No news from the reporter so I'm closing the issue.

I can confirm that this issue is still relevant (as mentioned by moala) in boost 1_56_0.

32bit Intel builds for 10.7.5 fail as above on LLVM GCC 4.2 - The mentioned workaround did indeed solve the problem for me also.

Note that I am static-linking boost, and forcing the compiler to GNU99 dialect. These may be related?

If needed I may be able to create a reproducing project.

darthpjb@… — Tue, 26 Aug 2014 18:34:07 GMT

I can now further confirm the issue is also apparent on I386 builds using LLVM GCC 5.1, for the 10.9 SDK, Xcode 5.1.1.

It would seem this does actively apply to the most recent LLVM compilers, across the full range of Mac OSX builds. As long as the target architecture is 32bit.

darthpjb@… — Wed, 27 Aug 2014 14:45:15 GMT

Further Confirmation: The issue is also present on OSX 10.5.8, Xcode 3.1.4, Using Apple GCC 4.0

Graham Perk's fix does, once again, solve the issue.

Without access to the platform, I can't know where the problem lies. However, one alternative could be specifying the template type in get_rounded_size. That is:

replace "get_rounded_size(a, b)" calls with "get_rounded_size<size_type>(a, b)".

Please let me know if this fixes the problem

For what it's worth, I had this same problem on OSX (with boost 1.56) and this workaround got things compiling.
