我需要怎么做才能使ZMQ_RADIO/ZMQ_DISH正常工作? [英] What do I need to do to get ZMQ_RADIO / ZMQ_DISH to work properly?
问题描述
我正在尝试使用ZMQ规范草案 ZMQ_RADIO 和 ZMQ_DISH .我使用CMake ExternalProject 和标志 ENABLE_DRAFTS = ON 构建了libzmq和cppzmq，并使用 zmq_has()函数验证了它是使用草稿构建的.我修改了标准您好世界示例以使用收音机和碟形天线，无法让他们通话.我还收到未定义 ZMQ_RADIO 和 ZMQ_DISH 的编译错误.我手动定义了它们并进行了编译，但我始终无法获得实际的连接，因此似乎有些其他问题.
I'm attempting to use the ZMQ draft specs ZMQ_RADIO and ZMQ_DISH. I built libzmq and cppzmq with CMake ExternalProject and and the flag ENABLE_DRAFTS=ON and verified it was built with drafts using the zmq_has() function. I modified the standard hello world example to use radio and dish and cannot get them to talk. I also get compilation errors that ZMQ_RADIO and ZMQ_DISH are undefined. I defined them manually and it compiles but I never get an actual connection so it seems like something else is wrong.
这是我的代码:

socket.connect ("udp://127.0.0.1:5555");
for (int request_nbr = 0; request_nbr != 10; request_nbr++)
{
zmq::message_t request (5);
memcpy (request.data (), "Hello", 5);
std::cout << "Sending Hello " << request_nbr << "…" << std::endl;
socket.send (request);
sleep(1);
}
return 0;
}
服务器为 zmq_has()函数输出预期的1，该函数应验证libzmq是在草稿API模式打开的情况下构建的.
The server outputs a 1 as expected for the zmq_has() function, which should verify libzmq was built with the draft API mode on.
我想在项目上使用ZMQ作为UDP接收器，以从非ZMQ应用程序接收一些UDP数据包.
I'd like to use ZMQ on a project as a UDP receiver to receive some UDP packets from a non-ZMQ application.
推荐答案
RADIO和DISH处于草稿状态，无法在稳定版本中使用.如果您需要访问DRAFT API，请从此链接
The RADIO and DISH are in draft state and not available in stable build. If you need to access DRAFT API, build zmq from this link
以下是 zmq.hpp
// These functions are DRAFT and disabled in stable releases, and subject to
// change at ANY time until declared stable.
#ifdef ZMQ_BUILD_DRAFT_API
//DRAFT Socket types.
#define ZMQ_SERVER 12
#define ZMQ_CLIENT 13
#define ZMQ_RADIO 14
#define ZMQ_DISH 15
#define ZMQ_GATHER 16
#define ZMQ_SCATTER 17
#define ZMQ_DGRAM 18
#endif
