使用 libcurl 链接程序时未解析的符号 [英] Unresolved symbols when linking a program using libcurl

问题描述

我知道这是编程问题，但我只是很沮丧试图找出我做错了什么..

I know this is programming questions but I'm just frustrated trying to figure out what I'm doing wrong..

我正在使用 Visual Studio 2010 并按照此处的所有步骤操作:http://curl.haxx.se/libcurl/c/visual_studio.pdf

I'm using visual studio 2010 and followed all the steps here: http://curl.haxx.se/libcurl/c/visual_studio.pdf

当我尝试编译我的解决方案时，我不断收到此错误:

When I try to compile my solution I keep getting this error:

#include "stdafx.h"

#include <curl/curl.h>

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

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://google.com");
    res = curl_easy_perform(curl);

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

推荐答案

看起来库没有成功链接.确保库目录设置为包含 libcurl dll 的完整路径.还要确保此库确实已添加到您的项目中.

Looks like the libraries are not being successfully linked. Ensure the library directory is set to include the full path to the libcurl dll. Also make sure this library is actually added to your project.
