//问题：在boost1.61.0+opencv3.1.0及c++98下编译不报错，在boost1.78.0+opencv4.6.0及c++17下编译报上述错误，请问哪位知道怎么解决吗，非常感觉

这个问题是由于Boost库的版本不兼容导致的。在Boost 1.78.0及更高版本中，std::allocator<none>已被弃用，取而代之的是std::allocator<void>。为了解决这个问题，你可以尝试将代码中的std::allocator<none>替换为std::allocator<void>。

首先，找到以下代码：

template< class Allocator = std::allocator< none > >

将其替换为：

template< class Allocator = std::allocator< void > >

然后，找到以下代码：

boost::statechart::fifo_worker<>,

将其替换为：

boost::statechart::fifo_worker<>,

最后，找到以下代码：

boost::statechart::processor_container<>,

将其替换为：

boost::statechart::processor_container<>,

完成这些更改后，重新编译项目，问题应该得到解决。
