C++ 未能编译curlpp

我已经做了几个小时了（就在今天），所以我真的需要一些帮助。我总是在Windows环境中编写代码，所以我尝试将curlpp添加到我的code:：Blocks项目中

我下载了curl-7.22.0-devel-mingw32，并将所有这些库添加到Code:：Blocks项目中

我下载了curl-7.22.0，并使用vc6curl.dsw进行编译，它生成了libcurl.lib，并将其添加到Code:：Blocks项目中

下载curlpp-0.7.3

将MinGW\lib\libwsock32.a添加到Code:：Blocks项目中

将以下目录添加到项目中： curlpp-0.7.3\包含和curl-7.22.0\包含

但是我得到了很多“未定义引用”错误，所以我猜这意味着curlpp也需要编译。它包含了VC8项目，所以我下载了Visual C++ 2005 Express并安装了。 我在打开项目时遇到的第一个错误是无法加载示例。我想这不是什么问题。尝试立即构建项目时，出现错误“无法打开包含文件：'curl/curl.h'”，因此我将curl includes文件夹curl-7.22.0\include添加到项目中，然后重试

一次又一次的错误，让我发疯。谷歌搜索那个也没什么帮助。我发现一些论坛帖子说必须添加WS2_32.Lib，这是在C:\Program Files（x86）\Microsoft SDK\Windows\v7.0A\Lib中，但将其添加到VS2005项目的libraries文件夹似乎没有任何作用

我都快忘了。。这是怎么回事？我认为这很简单：

编译卷曲

编译curlpp

利润 但不幸的是，这似乎并不那么容易

更新

哦，是的，我忘了，最初我也犯了以下错误：

c1xx : fatal error C1083: Cannot open source file: '.\src\curlpp\Infos.cpp': No such file or directory

c1xx : fatal error C1083: Cannot open source file: '.\src\curlpp\Option.cpp': No such file or directory

c1xx : fatal error C1083: Cannot open source file: '.\src\utilspp\singleton\LifetimeLibrary.cpp': No such file or directory

c1xx : fatal error C1083: Cannot open source file: '.\src\utilspp\singleton\PrivateMembers.cpp': No such file or directory

但是在src\curlpp中有：

Info.cpp
Options.cpp

所以我只是复制了它们，并将副本重命名为

Info2.cpp
Option.cpp

在src\utilspp中有

LifetimeLibrary.cpp
PrivateMembers.cpp

所以我只是在那里创建了一个文件夹“singleton”，并将文件复制到那里

就好像柯尔普是。。破碎的但我做的一定很奇怪，因为有人会注意到的

更新2 好的，我从头开始，我发现我还必须从WindowsSDK添加includes文件夹。这解决了无法打开包含文件：“winsock2.h”的错误。但现在我又犯了一大堆错误：

其中包括：

什么是推进路径

另外，为了消除“libcurl.lib未找到”错误，我打开了在curl-7.22.0中找到的项目并对其进行了编译，但这意味着libcurl.lib位于我包含的“lib\Debug”文件夹中，正如您在上面看到的，我这样做正确吗

更新3:

我注意到一个名为create-vc-solution.bat的文件，因此，在下载了windows版的“sed”之后，我尝试为VS9创建一个vc解决方案（10版没有选项），希望它能起作用，但当我打开在VS2010中创建的解决方案文件时，我得到了以下结果：

curlpp.examples.VC9.vcproj和curlpp.VC9.vcproj甚至从未创建过。curlpp是否已经过测试？有人吗？我开始认为这甚至不再是我的错。

我看到您正在将curlpp编译到动态库中。这就是你想要的吗？您应该将libcurl.lib添加到链接器输入中。

在深入研究此依赖关系之前，让我们从头开始。您是否正确设置了libcurl库，并且可以从您选择的开发环境中使用它？你能编译一个使用libcurl的演示应用程序吗。如果不是的话，你可能想看一看。实际上我已经设法让libcurl附带的C示例运行了，所以libcurl本身看起来不错。我也开始了这个教程：它工作（排序），但是每次我启动我的C++程序时，我都会得到“MSVCR80.DLL”，这是胡说八道，因为我安装了2005, 2008个和2010个运行时库。我也不明白。而且那个教程甚至没有使用curlpp，所以我还需要弄清楚这一点。我不知道什么是“动态”库，但我会用谷歌搜索它。“将libcurl.lib添加到链接器输入”。这就是我所说的

“2.我下载了curl-7.22.0，并使用vc6curl.dsw编译了它，它生成了libcurl.lib，并将其添加到code:：Blocks项目中。”
