我正在尝试从网站读取JSON数据。我在Windows 10上使用具有MinGW编译器的Dev C ++。这是我尝试在静态项目中运行的教程中的JSON解析器：

#define CURL_STATICLIB
#include <cstdint>
#include <iostream>
#include <memory>
#include <string>
#include <sstream>

#include "curl.h"
#include "json.h"

namespace
{
    std::size_t callback(
            const char* in,
            std::size_t size,
            std::size_t num,
            std::string* out)
    {
        const std::size_t totalBytes(size * num);
        out->append(in, totalBytes);
        return totalBytes;
    }
}

int main()
{
    const std::string url("http://date.jsontest.com/");

    CURL* curl = curl_easy_init();

    // Set remote URL.
    curl_easy_setopt(curl, CURLOPT_URL, url.c_str());

    // Don't bother trying IPv6, which would increase DNS resolution time.
    curl_easy_setopt(curl, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);

    // Don't wait forever, …
