I tried to compile a project but it failed with the following error: Build Error Below is the code in my project: boost::system::error_code ec; auto endpoints = resolver->resolver().resolve(ip_address, std::to_string(port)), ec); if (ec) return; // Connect to server boost::asio::ip::tcp::endpoint m_endpoint; m_endpoint = *(boost::asio::connect(_socket, endpoints.begin(), endpoints.end(), ec)); The problem occurs in the call to boost::asio::connect function.

I need to call method which is a request for a remote server. After that i want to wait for an answer, and waiting is not blocked by other asynchronous function/objects(timers for example). Method got_response(…) tells user that he got an answer from remote server, also method gets entry data which we got as an ..
I’m migrating my app from boost 1.72 to boost 1.75. The code was working with 1.72. but not for 1.75 I got this strange error when including boost/asio/ssl: boost/asio/ssl/impl/host_name_verification.ipp : error X509_check_ip_asc was not declared in this scope Have you any idea ? Thanks Source: Windows Que..
I would like to convert this asynchronous echo server to the same server, but using boost :: spawn. I’ve tried this, but I’m facing various problems: it is not possible to pass a non-static function to spawn. I want to pass a function, and not write a lambda every time (as is done in the ..
For a client side application, I wish to serialize http post requests using strand, in order to avoid overlapping writes/ responses to/from the server. Serialization is made using boost::asio, by calling the method as a callback from strand.post as shown below. Notice that inside each http session (write request and read it’s response, is made ..
I’d like to serialize http post requests using strand, to avoid overlapping writes to network. My approach was to call the post method from the strand object with the callback that send the data as can be shown in the following code : void Send( boost::beast::http::request<boost::beast::http::string_body> &req) { strand_.post([=]() { … boost::beast::http::write(stream_, req); … } ..
I wanted to try out to c++20 coroutines together with asio. In a simple test three are coroutines which would be executed on a asio::thread_pool with 4 threads. When I run the test all the coroutines are executed one-by-one after each other, and not simultaneously. This is not the behavior that I expected. I thought ..
I am trying to get My modem IPV4 by using boost Asio and c++, For doing this I try this code : try { boost::asio::io_service netService; udp::resolver resolver(netService); udp::resolver::query query(udp::v4(), "google.com", ""); udp::resolver::iterator endpoints = resolver.resolve(query); udp::endpoint ep = *endpoints; udp::socket socket(netService); socket.connect(ep); boost::asio::ip::address addr = socket.local_endpoint().address(); std::cout << "My IP according to google is: ..
So currently I am following a tutorial on writing sockets using ASIO on youtube https://www.youtube.com/watch?v=2hNdkYInj4g&ab_channel=javidx9, really great guy. I am not sure the proper way to ask questions. Here goes… So I have 2 projects, first project NetCommon, I have created a header file, olc_net.h to include all header files In tutorial he just links ..
I have a cnx class which represents a socket and it must also has a timer in which if the clients stays more than cnx::timeout_mili milliseconds without responding then I’ll close the connection. Each timer will start when the connection is made, or, when the cnx object is instantiated. The socket part is working fine, ..
