02_c/c++开源库ZeroMQ

1.安装

C库 libzmq

sudo apt install libzmq3-dev

实例: https://zeromq.org/get-started/?language=c\&library=libzmq#

编译依赖:
pkg-config --cflags --libs libzmq or cat /usr/lib/x86_64-linux-gnu/pkgconfig/libzmq.pc

-isystem /usr/include/mit-krb5 -I/usr/include/pgm-5.2 -lzmq

只使用ZMQ基本功能, 添加链接选项 -lzmq 即可

编译选项: 无

链接选项: -lzmqpp

---

C++库 libzmqpp

sudo apt install libzmqpp-dev

实例: https://zeromq.org/get-started/?language=cpp\&library=zmqpp#

编译依赖

1. 不支持.pc 格式查看
2. 通过安装位置, 可知头文件,动态库位置

/usr/include/zmqpp/zmqpp.hpp

/usr/lib/x86_64-linux-gnu/libzmqpp.so

编译选项: 无

链接选项: -lzmqpp

1_zmqpp_sub订阅端.cc

#include <iostream>
#include <string>
#include <zmqpp/zmqpp.hpp>
using namespace std;
int main(int argc, char *argv[])
{
    zmqpp::context context;
    const string addr_port = "tcp://localhost:5555";
    zmqpp::socket_type type = zmqpp::socket_type::subscribe;
    zmqpp::socket socket = zmqpp::socket(context, type);
    socket.set(zmqpp::socket_option::subscribe, "");
    socket.connect(addr_port);
    while (1)
    {
        zmqpp::message message;
        socket.receive(message);
        std::cout << "recv data: " << message.get(0) << std::endl;
    }
    return 0;
}

#include <iostream>
#include <string>
#include <zmqpp/zmqpp.hpp>
#include <unistd.h>
using namespace std;
int main()
{
    zmqpp::context context;
    const string addr_port = "tcp://*:5555";
    zmqpp::socket_type type = zmqpp::socket_type::publish;
    zmqpp::socket socket = zmqpp::socket(context, type);
    socket.bind(addr_port);
    int i = 0;
    while (i < 100)
    {
        zmqpp::message message;
        message << "test[" + to_string(i++) + "]";
        socket.send(message);
        sleep(1);
    }
    return 0;
}

2.scons构建

SConstruct

## 模板2
env = Environment()
env["PROGSUFFIX"] = ".out"            # 可执行后缀.out
env["CCFLAGS"] = " -g3 -O0 -Wall"  # gdb 调试开关
env["LIBS"]=["zmqpp","zmq","protobuf"]
env.Program("1_zmqpp_sub订阅端.cc")
env.Program("2_zmqpp_pub发布端.cc")

scons

scons: Reading SConscript files ...

scons: done reading SConscript files.
