hazelcast c ++客户端示例不断崩溃

Question

• 我已经尝试在Windows中使用最简单的示例使用hazelcast c ++，例如

#include <hazelcast/client/HazelcastClient.h>

int main() {
    hazelcast::client::ClientConfig config;
    hazelcast::client::HazelcastClient hz(config);
    std::cout << "Started the Hazelcast C++ client instance " << hz.getName() << std::endl;
}

但是它一直崩溃

• 我已经下载了“ hazelcast-cpp-client-3.12.1-Windows_64”，并使用Visual Studio 2019进行了编译
• 在/ bin目录中，我执行了start.bat文件，服务器弹出并运行

• 我写了代码来测试连接（代码如上），但是显示这些消息却失败了>]

Hazelcast v4.0的cpp客户端尚未发布，并且客户端的3.x版本与其不兼容。您现在可以尝试在服务器中使用Hazelcast 3.x。
