使LibCurl与Visual Studio 2013配合使用 [英] Getting LibCurl to work with Visual Studio 2013

问题描述

我无法使LibCurl与Visual Studio 2013一起工作。我下载了当前版本（curl-7.33.0），并尝试按照我在此网站上找到的说明：
添加libcurl库并成功编译后，我现在得到此错误消息：

 应用程序无法正确启动（0xc000007b ）。单击确定关闭应用程序。 
  

这里是我试图运行的示例代码：

  #include< iostream> 
 #include< stdio.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; 
}

我相信我已经让LibCurl与Visual Studio 2013合作了。持续性
虽然，花了几个小时试图解决这些错误消息，我有点犹豫，说一切都工作正常现在。这就是为什么我要对这个问题提供一个赏金，以获得清楚和简洁的指示关于获取LibCurl工作与Visual Studio 2013.

这个是我做的，让它工作：

1. 首先，下载Win32 MSVC包这里： http://curl.haxx.se/download.html#Win32
   为了这些说明，我们假设您下载到C ：\LibCurl




2. 在Visual Studio中启动一个新项目。转到项目|项目属性| VC ++目录|包括目录|
   将路径添加到下载的包中的include目录。 （C：\LibCurl\include）




3. 接下来，转到项目|项目属性|
   将路径添加到lib目录。




4. 然后，转到Project | Project Properties | Linker | Input | Additional Dependencies |
   并添加 curllib.lib




5. 现在如果你编译一个测试程序，你可能会得到libsasl .dll缺失。您将需要下载此文件，并将其放在与您的构建相同的目录。
   我使用7-Zip从 OpenLDAP for Windows 中提取 libsasl.dll 。 适用于Windows的OpenLDAP

这是我上面的测试代码的结果：

解决方案

我会说在评论，但我缺乏点。
您不必将任何.dll复制到程序运行目录中。
转到项目|属性|配置属性和环境变量： PATH = $（ExecutablePath）$（LocalDebuggerEnvironment）。

从现在起，项目|项目属性| VC ++目录|二进制中提到的任何目录中的所有.dll文件都应该可以使用，无需复制。

其余的就是你写的。

I am having trouble getting LibCurl to work with Visual Studio 2013. I downloaded the current version (curl-7.33.0) and tried following the instructions I found on this site: Using LibCurl with Visual 2010

But I can't find curllib.lib in the folder I downloaded. And I am still getting errors:

After searching the internet for more help. I now get these error messages. There appears to be a problem with linking to libcurl.lib?

This is what I have configured:

---

Inside /lib I have libcurl.lib and libcurl.dll

---

UPDATE

I downloaded this release for Win32 MSVC: http://curl.haxx.se/download.html#Win32 After adding the libcurl libraries and successfully compiling, I am now getting this error message:

 The application was unable to start correctly (0xc000007b). Click OK to close the application.

Here is the sample code I am trying to run:

#include <iostream>
#include <stdio.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;
}

FINAL UPDATE

I believe I have gotten LibCurl to work with Visual Studio 2013 now. Persistence ftw! Although, after spending hours trying to solve these error messages, I am a little hesitant at saying everything is working fine now. That is why I am putting a bounty on this question to get clear and concise instructions on getting LibCurl to work with Visual Studio 2013.

This is what I did to get it to work:

1. First, download the Win32 MSVC package here: http://curl.haxx.se/download.html#Win32 For these instructions sake, let's say you downloaded to C:\LibCurl

2. Start a new project in Visual Studio. Go to Project|Project Properties|VC++ Directories|Include Directories| Add the path to the include directory inside the downloaded package. (C:\LibCurl\include)

3. Next, go to Project|Project Properties|Linker|General|Additional Library Directories| Add the path to the lib directory. (Where curllib.dll is located)

4. Then, go to Project|Project Properties|Linker|Input|Additional Dependencies| And add curllib.lib

5. Now if you compile a test program, you will likely get the message saying libsasl.dll is missing. You will need to download this file and put it in the same directory as your build. I used 7-Zip to extract libsasl.dll from OpenLDAP for Windows. OpenLDAP for Windows

This is the result of my test code from above:

解决方案

I would say that in a comment, but I am lacking in points. You don't have to copy any .dll into your program run catalog. Go to Project | Properties | Configuration Properties and in line Envrionment write: PATH=$(ExecutablePath)$(LocalDebuggerEnvironment).

From now on, all .dlls from any catalog you mention in Project|Project Properties|VC++ Directories|Binary should be usable without copying them.

The rest is exactly as you written.
