C/C++编程：ZeroMQ安装以及使用（windows+centos）

落日映苍穹つ 2022-11-06 14:00 2338阅读 0赞

>  *  ZeroMQ（也称为ØMQ，0MQ或ZMQ）是一种高性能的异步消息传递库，旨在用于分布式或者并发应用程序中。它提供了一个消息队列，但是与面向消息的中间件不同，ZeroMQ系统可以在没有专用消息代理的情况下运行。
>  *  ZMQ通过各种传输(TCP、进程内、进程间、多播、WebSocket等)支持通用消息传递模式(发布/订阅、请求/回复、客户端/服务器等)，从而使消息传递变得简单。
>  *  ZeroMQ由大型贡献者社区开发。有许多流行编程语言的第三方绑定以及C＃和Java的本机端口。
>  *  ZeroMQ的理念从零开始。零表示零代理（ZeroMQ是无代理），零延迟，零成本（免费）和零管理。
>  *  更广泛地说，“零”是指渗透到项目中的极简主义文化。我们通过消除复杂性而不是通过公开新功能来增加功能。

# C #

*  C开发人员可以使用两个选项CZMQ或libzmq（低级zeromq库）。
 *  对于C开发人员，推荐的绑定是CZMQ，它为ØMQ提供了一个高级API，并带有诸如轮询器，线程管理和安全性助手之类的其他类。

### 安装 ###

vcpkg  install czmq:x64-windows

### 编写cmake ###

cmake_minimum_required (VERSION 3.8)
    
    
    add_executable (zmp_server "zmp_server.cpp" "zmp_server.h")
    
    
    
    include_directories("C:/Users/oceanstar/vcpkg/win/vcpkg/installed/x64-windows/include")
    link_directories("C:/Users/oceanstar/vcpkg/win/vcpkg/installed/x64-windows/lib")
    
    find_package(czmq CONFIG REQUIRED)
    target_link_libraries(${
        PROJECT_NAME}  PRIVATE czmq czmq-static)

### 例子 ###

#include <czmq.h>
    int main(void)
    {
        
        zsock_t* push = zsock_new_push("inproc://example");
        zsock_t* pull = zsock_new_pull("inproc://example");
        zstr_send(push, "Hello, World");
    
        char* string = zstr_recv(pull);
        puts(string);
        zstr_free(&string);
    
        zsock_destroy(&pull);
        zsock_destroy(&push);
        return 0;
    }

效果： 出现错误Assertion failed: Successful WSASTARTUP not yet performed (…\\src\\signaler.cpp:192)

解决：

#include <czmq.h>
    int main(void)
    {
        
        zsock_t* push = zsock_new_push("inproc://example");
        zsock_t* pull = zsock_new_pull("inproc://example");
        zstr_send(push, "Hello, World");
    
        char* string = zstr_recv(pull);
        puts(string);
        zstr_free(&string);
    
        zsys_shutdown();
        zsock_destroy(&pull);
        zsock_destroy(&push);
        return 0;
    }

# C++ #

*  C开发人员可以使用四个选项：cppzmq、zmqpp、azmq、czmqpp
    
     *  cppzmq是libzmq的C ++绑定
     *  zmqpp是libzmq的高级绑定。
     *  czmqpp是基于高级czmq API的绑定。
     *  fbzmq是与Apache Thrift集成的绑定，此外还提供更高级别的抽象。它需要C ++ 14。

## windows + vs2019 + cmake + cppzmq ##

*  Github：[https://github.com/zeromq/cppzmq][https_github.com_zeromq_cppzmq]

### 安装 ###

vcpkg install cppzmq:x64-windows

### 编写cmake ###

cmake_minimum_required (VERSION 3.8)
    
    add_executable (zmp_server "zmp_server.cpp" "zmp_server.h")
    
    include_directories("C:/Users/oceanstar/vcpkg/win/vcpkg/installed/x64-windows/include")
    link_directories("C:/Users/oceanstar/vcpkg/win/vcpkg/installed/x64-windows/lib")
    
    find_package(cppzmq CONFIG REQUIRED)
    target_link_libraries(${
        PROJECT_NAME} PRIVATE cppzmq cppzmq-static)

### 例子 ###

#include <string>
    #include <zmq.hpp>
    int main()
    {
        
       zmq::context_t ctx;
       zmq::socket_t sock(ctx, zmq::socket_type::push);
       sock.bind("inproc://test");
       const std::string_view m = "Hello, world";
       sock.send(zmq::buffer(m), zmq::send_flags::dontwait);
    }

## centos+ clion+ cmake + cppzmq ##

`centos + clion + cmake + libzmq`这个目录处下载的默认只有<zmq.h>头文件，这个文件是ZeroMQ开发的C语言版本。如果想要使用C++开发版本的<zmq.hpp>头文件，那么需要自己下载zmq.hpp文件，然后复制到我们ZeroMQ安装路径的include目录下就可以了

wget https://github.com/zeromq/cppzmq/archive/master.zip
    
    unzip master.zip
    
    
    cd cppzmq-master
    
    sudo cp ./zmq.hpp /usr/local/include

问题：执行`./ci_build.sh`

CMake Error at tests/CMakeLists.txt:51 (catch_discover_tests):
      Unknown CMake command "catch_discover_tests".

解决： `yum install catch-devel`无法解决
