使用 Boost 在共享内存中创建循环缓冲区时出现问题

我正在尝试使用 Boost circular_buffer 和 Interprocess 库在共享内存中创建循环缓冲区。我编译并运行了进程间文档，用于在共享内存中毫无问题地创建向量。但是，当我修改它以使用 Boostcircular_buffer 时：

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;
}

我收到编译错误（由 segment.construct() 引起）。知道我做错了什么吗？是否因为circular_buffer不是/boost/interprocess/containers中列出的容器之一，即它与Interprocess不兼容？

谢谢，

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,
