问题描述

我在让 LibCurl 与 Visual Studio 2013 一起工作时遇到问题.我下载了当前版本 (curl-7.33.0) 并尝试按照我在本网站上找到的说明进行操作:添加 libcurl 库并成功编译后，我现在收到此错误消息:

 应用程序无法正确启动 (0xc000007b).单击确定关闭应用程序.

这是我尝试运行的示例代码:

#include #include #include int main(void){卷曲 *卷曲；CURLcode res;curl = curl_easy_init();如果(卷曲){curl_easy_setopt(curl, CURLOPT_URL, "http://google.com");res = curl_easy_perform(curl);/* 总是清理 */curl_easy_cleanup(卷曲)；}返回0；}

最终更新

我相信我现在已经让 LibCurl 与 Visual Studio 2013 一起工作了.坚持ftw！虽然，在花了几个小时试图解决这些错误消息之后，我还是有点犹豫现在一切正常.这就是为什么我在这个问题上悬赏以获取关于让 LibCurl 与 Visual Studio 2013 一起使用的清晰简洁说明.

这是我为了让它工作而做的:

1. 首先，在此处下载 Win32 MSVC 包:http://curl.haxx.se/download.html#Win32为了这些说明，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|包含目录|将路径添加到下载的包内的包含目录中.(C:LibCurlinclude)

3. 接下来，转到项目|项目属性|链接器|常规|附加库目录|添加lib目录的路径.(curllib.dll 所在的位置)

4. 然后，转到项目|项目属性|链接器|输入|其他依赖项|并添加 curllib.lib

5. 现在，如果您编译测试程序，您可能会收到消息，指出缺少 libsasl.dll.您需要下载此文件并将其放在与构建相同的目录中.我使用 7-Zip 从 OpenLDAP for Windows 中提取 libsasl.dll.Windows 版 OpenLDAP

这是我上面的测试代码的结果:

我会在评论中说，但我缺乏要点.您不必将任何 .dll 复制到您的程序运行目录中.转到项目|属性 |配置属性并在环境中写入:PATH=$(ExecutablePath)$(LocalDebuggerEnvironment).

从现在开始，您在项目|项目属性|VC++ 目录|二进制中提到的任何目录中的所有 .dll 都应该可以使用而无需复制.

其余的和你写的完全一样.

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:LibCurlinclude)

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:

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.
