boost version is wrong.

[eternally123]

An error occurred while compiling muduo:

/home/shiliangw/code/muduo/examples/ace/ttcp/ttcp_asio_async.cc:147:76: error: ‘boost::asio::ip::tcp::acceptor’ {aka ‘class boost::asio::basic_socket_acceptorboost::asio::ip::tcp’} has no member named ‘get_io_service’
147 | TtcpServerConnectionPtr new_connection(new TtcpServerConnection(acceptor.get_io_service()));

i thought it is because of the version of boost is wrong,but i don't which version can fit muduo.

the environment in my os:
gcc 9.2.0
cmake 3.15.4
boost 1.71

i want to know which version suits muduo
thanks

Try boost 1.69 or below, get_io_service() was removed in 1.70.0.

Another easy solution to this when you want to use boost 1.70 and above is to use get_executor() instead of get_io_service(). The ctor of TtcpServerConnection should be changed, too.

I've opened a PR #451 , it can fix this error.
UPDATE: The PR is merged now.
