Question

我正在尝试将curl添加到我的项目上的codeblocks（Windows 10）。我在链接器设置中链接了libcurl的.a文件，并在搜索目录中添加了include文件。但是，当我尝试运行示例代码时

#include <stdio.h>
#include <iostream>
#include <json.hpp>
#include <curl/curl.h>

using namespace std;

int main()
{
  CURL *curl;
  CURLcode res;

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
    /* example.com is redirected, so we tell libcurl to follow redirection */
    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);

    /* Perform the request, res will get the return code */
    res = curl_easy_perform(curl);
   /* Check for errors */
   if(res != CURLE_OK)
     fprintf(stderr, "curl_easy_perform() failed: %s\n",
          curl_easy_strerror(res));

  /* always cleanup */
  curl_easy_cleanup(curl);
  }
  return 0;
}

但我仍然遇到一堆错误（不介意我的用户名）

任何人都知道会出现什么问题？

尝试在代码块中使用curl，获得大量＆＃34;未定义的引用＆＃34;错误
