Hi,

The lines of code you posted seem to be ok, so the problem is somewhere in
the code you haven't posted here. Ensure that your io_service is initialized
*before* you pass it to the other asio objects, and that the socket is
initialized before you pass it to the acceptor.
Here is an example of how you should use the acceptor:
