在项目中包含libcurl [英] Including libcurl in project

问题描述

所以我从curl网站下载了zip文件。我将所有头文件的目录复制到我的include目录中。包括curl.h的工作没有问题，但是，当我去实际调用一个函数，突然我的c ++应用程序将不再编译。

这里是错误我' m接收：

  [链接器错误]未定义引用
`curl_easy_init'
  

以下是代码：

  #define CURL_STATICLIB 
 #include< curl / curl.h> 
 #include< string> 
 #include< iostream> 
 using namespace std; 
 
 int main（）{
 string url =http://www.google.com; 
 cout<< 检索<< url<< endl; 
 
 //我们的curl对象
 CURL * curl; 
 CURLcode result; 
 
 //创建我们的curl句柄
 curl = curl_easy_init（）; 
 
系统（pause）; 
 
 return 0; 
} 
  

如果我注释掉curl = curl_easy_init / p>

根据文档，这应该可以工作，

解决方案

p>您必须将程序与curl库链接

  -L / path / of / curl / lib / libcurl.a 
 
  $ b <$> 

Solution-> properties->链接（ing）并添加libcurl.lib





So I downloaded the zip file from the curl website. I copied the directory with all of the header files into my include directory. Including the curl.h works with no problems, however, when I go to actually call a function, suddenly my c++ app will no longer compile.

Here's the error I'm receiving:

 [Linker error] undefined reference to
 `curl_easy_init'

Here's the code:

#define CURL_STATICLIB
#include <curl/curl.h>
#include <string>
#include <iostream>
using namespace std;

int main() {
      string url = "http://www.google.com";
      cout << "Retrieving " << url << endl;

      // Our curl objects
      CURL *curl;
      CURLcode result;

      // Create our curl handle  
      curl = curl_easy_init();  

    system("pause");

    return 0;
}

It works fine if I comment out the curl=curl_easy_init() line.

According to the documentation this should work, as seen here.

Any ideas?

解决方案

you must link your program with the curl library

-L/path/of/curl/lib/libcurl.a (g++)

or add curl in your solution

Solution->properties->Link(ing) and add libcurl.lib
