Hi Cuneyt,

the circular buffer should be compatible with Interprocess - the only 'problem' is that the circular buffer's debug support relies on 'raw' pointers. Try compiling with -DBOOST_CB_DISABLE_DEBUG or -DNDEBUG. I believe this will help.

Regards,

Jan

Hi,
I am trying to create a circular buffer in shared memory using Boost circular_buffer  and Interprocess libraries. I compiled and ran the the example given in  the Interprocess documentation for creating a vector in  shared memory with no problem. However, when I modify it to use the  Boost circular_buffer as: 
int main(int argc, char *argv[])
{
    managed_shared_memory segment(create_only, "MySharedMemory", 65536);
    constShmemAllocatoralloc_inst (segment.get_segment_manager());
    MyCircBuffer  *myCircBuf  = segment.construct<MyCircBuffer>("MyCircBuffer")(alloc_inst);
    return 0;
}

I get a compilation error (caused by segment.construct()). Any idea what I am doing wrong? Is it because circular_buffer is not one of the containers listed in /boost/interprocess/containers, i.e. it's not compatible with Interprocess?
Thanks,
C
