How do I create a TCP server using Boost.Asio in C++?

To create a TCP server using Boost.Asio, you'll need to set up an io_context, create an acceptor, and handle incoming connections.

Can you provide a simple code example?

Sure! Here's a basic example:

#include <boost/asio.hpp>
#include <iostream>

using boost::asio::ip::tcp;

int main() {
    boost::asio::io_context io_context;
    tcp::acceptor acceptor(io_context, tcp::endpoint(tcp::v4(), 12345));

    while (true) {
        tcp::socket socket(io_context);
        acceptor.accept(socket);
        std::cout << "Client connected!" << std::endl;
    }
    return 0;
}

What do I need to link against to compile this code?

You need to link against the Boost.System library. You can do this by adding -lboost_system to your compile command.

Are there any common issues I should be aware of?

Yes, common issues include not having the Boost library installed, incorrect port usage, and handling exceptions properly.
