Question

我正在尝试在我的电脑上安装ZeroMQ，但我不能让我的程序在没有崩溃的情况下运行安装：

1) install Visual Studio 2017.

2) clone from git jzmq and libzmq

3) install ZMQ version 4.0.4 for windows.

4) run the script build in: \libzmq\builds\msvc\build\build.bat

5) open in Visual Studio 2017: libzmq\builds\msvc\vs2017\libzmq.sln and jzmq\jzmq-jni\builds\msvc\msvc.sln.

6) rebuild in the Visual Studio 2017 the sln files:

+ libzmq.sln : in the properties: configuration: Active(DebugDLL) platform: Active(x64)

+ msvc.sln : in the properties: configuration:Release platform: Active(x64)
label VC++ Directories: update the include directories and Library directories,
label Linker -> Input: update the Additional Dependencies with - C:\git-repo\libzmq\bin\x64\Debug\v141\dynamic\libzmq.lib;%(AdditionalDependencies)

7) put the libzmq.dll and the jzmq.dll in the system32 folder.

完成安装后，我尝试运行简单的Java示例，看看是否一切正常：
java代码：

import org.zeromq.ZMQ;
import java.nio.charset.Charset;

public class TestMainClass {

public static void main(String[] args){
    try {
        ZMQ.Context context = ZMQ.context(1);
        ZMQ.Socket replier = context.socket(ZMQ.REP);
        replier.bind("tcp://*:5559");

        while (true) {

            String gwSource = replier.recvStr(Charset.defaultCharset());
            replier.send("OK");
            System.out.println(gwSource);
        }
    }catch (Throwable e) {
        System.out.println(e);
    }
  }
}

import org.zeromq.ZMQ;

public class Requester {

public static void main(String[] args){
    ZMQ.Context context = ZMQ.context(1);
    ZMQ.Socket replier = context.socket(ZMQ.REQ);
    replier.connect("tcp://localhost:5559");

    while (true) {
        replier.send("public");
        System.out.println(new String(replier.recv()));
    }
  }
}

领事输出：

TestMainClass尝试接收响应并打印后程序崩溃：处理以退出代码-1073740791（0xC0000409）

结束

我认为导致失败的安装有问题，但我找不到问题。

Answer 1

好的，Alea Acta Est：

如何调试根本原因？

等级0：首先发送 int -s，而不是任何 string -s（其中）有不同的附加字符集问题）

等级1 ：尝试 .recv() 方法的非阻止模式（从{{1}的非阻止模式返回方法调用最终将证明ZeroMQ-part不是问题）

安装和运行ZeroMQ
