如何在我的C项目中的代码块（Windows）中包含curl库？ [英] How do I include curl library in my C project in Code Blocks (Windows)?

问题描述

这个问题似乎很简单。我尝试了很多东西，只是为了包括curl在我的C项目使用代码:: blocks ide但没有效果。

The question seems straight forward. I tried a lot of things just to include curl in my C project using the code::blocks ide but to no avail.

我想使用cURL的库控制台应用程序需要http功能。
如果任何人已经成功这样做，那么你的帮助是非常感谢。 ：）

I would like to use cURL's library for my console app project that needs http capabilities. If anyone had successfully done so, then your help is very much appreciated. :)

之前发生了什么：

- 我将所有cURL文件复制到我的项目，具有.a或.lib ext的那些。）

-I copied all cURL files to my project and linked the libraries (the ones with .a or .lib ext.)

- 当我构建项目时。很多未定义的引用出现了。

-Then when I build the project. A lot of undefined reference showed up.

这是我测试的代码：

#include <stdio.h>
#include <stdlib.h>
#include <curl/curl.h>

    int main()
    {
     curl_global_init( CURL_GLOBAL_ALL );
     CURL * myHandle;
     CURLcode result; 
     myHandle = curl_easy_init ( ) ;

     curl_easy_setopt(myHandle, CURLOPT_URL, "http://www.example.com");
     result = curl_easy_perform( myHandle );
     curl_easy_cleanup( myHandle ); 
     printf("LibCurl rules!\n");
     return 0;
    }

以下是错误：

||=== Fa, Release ===|
obj\Release\main.o:main.c|| undefined reference to `_imp__curl_global_init'|
obj\Release\main.o:main.c|| undefined reference to `_imp__curl_easy_init'|
obj\Release\main.o:main.c|| undefined reference to `_imp__curl_easy_setopt'|
obj\Release\main.o:main.c|| undefined reference to `_imp__curl_easy_perform'|
obj\Release\main.o:main.c|| undefined reference to `_imp__curl_easy_cleanup'|
||=== Build finished: 5 errors, 0 warnings ===|

推荐答案

转到您的项目Build Options链接器选项卡，因此您有两个选择：

Go to your project "Build Options" -> "Linker" tab and so you have two choices:

1. 如果您的库已正确安装在系统范围，其他链接器选项的lib，就像你直接使用你的编译器。
   对于GCC，您可以写 -lcurl 。您还可以使用此路径指令，如 wl，-rpath，/ path / to / your / library -lMyLib 。显然，这取决于编译器和系统设置。

1. If your library is (correctly) installed system-wide, write in "other linker options" the libs as if you were using your compiler directly. For GCC you'd write -lcurl. You may also use this with a path instruction like Wl,-rpath,/path/to/your/library -lMyLib. Obviously it depends on the compiler and system setup.

将库添加到左侧的链接库点击添加按钮并浏览到您的图书馆文件。

Add the library in "Link libraries" on the left. Click the "Add" button and browse to your library file.
