Linux下编译并使用ZeroMQ

（1）下载ZeroMQ以及头文件zmq.hpp

ZeroMQ：http://download.zeromq.org/

zmq.hpp：https://github.com/zeromq/cppzmq/archive/master.zip

（2）编译生成动态库

 1.解压

tar -xvf zeromq-4.1.2.tar.gz

2.编译

cd zeromq-4.1.2
./configure --prefix=/home/libdev/zmq --without-libsodium
make && make install

如果第二步报错：

则执行以下命令：

./configure --prefix=/home/libdev/zmq --without-libsodium

3.示例以及编译、运行

服务端：Server

hwserver.cpp

#include 
#include 
#include 
#include 

int main () {
    // Prepare our context and socket
    zmq::context_t context (1);
    zmq::socket_t socket (context, ZMQ_REP);
    socket.bind ("tcp://*:5555");

    while (true) {
        zmq::message_t request;

        // Wait for next request from client
        socket.recv (&request);
        std::cout << "Received Hello" << std::endl;

        // Do some 'work'
        sleep (1);

        // Send reply back to client
        zmq::message_t reply (5);
        memcpy ((void *) reply.data (), "World", 5);
        socket.send (reply);
    }
    return 0;
}

客户端：Client

hwclient.cpp

//
// Hello World client
// Connects REQ socket to tcp://localhost:5555
// Sends "Hello" to server, expects "World" back
//
#include 
#include 
#include 
#include 

int main (void)
{
    void *context = zmq_init (1);

    // Socket to talk to server
    printf ("Connecting to hello world server…\n");
    void *requester = zmq_socket (context, ZMQ_REQ);
    zmq_connect (requester, "tcp://localhost:5555");

    int request_nbr;
    for (request_nbr = 0; request_nbr != 10; request_nbr++) {
        zmq_msg_t request;
        zmq_msg_init_size (&request, 5);
        memcpy (zmq_msg_data (&request), "Hello", 5);
        printf ("Sending Hello %d…\n", request_nbr);
        zmq_msg_send (&request, requester, 0);
        zmq_msg_close (&request);

        zmq_msg_t reply;
        zmq_msg_init (&reply);
        zmq_msg_recv (&reply, requester, 0);
        printf ("Received World %d\n", request_nbr);
        zmq_msg_close (&reply);
    }
    zmq_close (requester);
    zmq_term (context);
    return 0;
}

编译命令：

g++ -g -Wall -fPIC -I/home/libdev/zmq/include -L/home/libdev/zmq/lib -lzmq hwserver.cpp -o server 

g++ -g -Wall -fPIC -I/home/libdev/zmq/include -L/home/libdev/zmq/lib -lzmq hwclient.cpp -o client

如果编译出错，请下载zmq.hpp放入zmq安装目录的include目录下

4.运行

./server

./client
