Problem creating a circular buffer in shared memory using Boost

Question

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);
    const ShmemAllocator alloc_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

I asked the same question on the boost user forum and the solution that was suggested was to use -DBOOST_CB_DISABLE_DEBUG or -DNDEBUG flags, since circular_buffer relies on raw pointers for debug support.

Any other suggestions?
