Boost ASIO TCP计时器客户端错误“解决：找不到指定的类”

Question

I am following Boost's TCP Timer tutorial here to learn TCP and UDP. I comment out the argc check, and change the following line:

tcp::resolver::query query(argv[1], "daytime");

into:

tcp::resolver::query query("127.0.0.1", "daytime");

Having the server code run on the same machine, I then ran the client code. This error is thrown:

resolve: The specified class is not found

Using the debugger, the error comes from this line:

tcp::resolver::iterator endpoint_iterator = resolver.resolve(query);

which is right below the query declaration. Can someone point me to where the error comes from, and how to fix it? Thanks.

Answer 1

Found the answer. The server code specified port number 13. I just need to change the line:

tcp::resolver::query query("127.0.0.1", "daytime");

into:

tcp::resolver::query query("127.0.0.1", "13");
