无法编译curlpp

Question

我已经在这几个小时了(这就是今天)所以我真的可以使用一些帮助.我总是在Windows环境中编写代码,所以我试图将curlpp添加到我的Code :: Blocks项目中.

1. 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.
2. 我下载了curl-7.22.0并使用vc6curl.dsw编译了libcurl.lib,将其添加到Code :: Blocks项目中.
3. 已下载curlpp -0.7.3
4. 将MinGW\lib\libwsock32.a添加到Code :: Blocks项目中.
5. 在项目中添加了以下目录: curlpp-0.7.3\include和curl-7.22.0\include

但是我得到了很多"未定义的引用"错误,所以我猜这意味着curlpp也需要编译.它包含一个VC8项目,所以我下载了Visual C++ 2005 Express并进行了安装.

打开项目时遇到的第一个错误是无法加载示例.我想这不是一个真正的问题.尝试立即构建项目,给出错误"无法打开包含文件:'curl/curl.h'",因此我将cURL include文件夹curl-7.22.0\include添加到项目中,然后重试.

错误时出错,这让我疯狂.Googeling一个人也没有真正帮助.我发现一些论坛帖子说必须添加WS2_32.Lib,并且在C:\ Program Files(x86)\ Microsoft SDKs\Windows\v7.0A\Lib中,但是将其添加到VS2005项目中的libraries文件夹中好像什么都做.

我只是在忘记这一切......这应该是怎么回事？我认为它会像下面这样简单:

1. 编译卷曲
2. 编译curlpp
3. 利润!

但不幸的是,它似乎并不那么容易.

UPDATE

哦是的,我忘记了,最初我也遇到了这些错误:

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

但在src\curlpp中有:

Info.cpp
Options.cpp

所以我只是将它们复制并重命名为

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.

好像curlpp被打破了？但它一定是我正在做的奇怪事情,因为有人会注意到!

UPDATE2 好的我从头开始并想通了我还必须从windows SDK 添加includes文件夹.这照顾了无法打开包含文件:'winsock2.h'错误.但现在我得到了一些其他错误:

这会永远结束吗？

其他库现在看起来像这样:

"C:\Users\admin\Downloads\curl-7.22.0\curl-7.22.0\lib\Debug";
"C:\Program Files (x86)\CodeBlocks\MinGW\lib";
"C:\Users\admin\Downloads\curl-7.22.0\curl-7.22.0\lib";
"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib";
"C:\Program Files\Microsoft SDKs\Windows\v7.1\Lib"

包括:

"C:\Program Files\Microsoft SDKs\Windows\v7.1\Include";
"C:\Users\admin\Downloads\curl-7.22.0\curl-7.22.0\include";
.\;
include\curlpp;
include;
"$(BOOST_PATH)"

什么是BOOST PATH？

而且,为了摆脱"libcurl.lib not found"错误,我打开了我在curl-7.22.0中找到并编译它的项目,但这意味着libcurl.lib位于"lib\Debug"文件夹中,我你可以看到,如上所述,我是否正确地做到了？

UPDATE3:

我注意到一个名为create-vc-solution.bat的文件,因此,在为windows下载"sed"之后,我尝试为VS9创建一个vc解决方案(10没有选项)希望这样可行,但这就是我得到的内容打开在VS2010中创建的解决方案文件:

从未创建过curlpp.examples.VC9.vcproj和curlpp.VC9.vcproj.curlpp有没有经过测试？任何人？我开始认为这不再是我的错了.

我看到你正在将curlpp编译成动态库。这就是你想要的吗？您应该将libcurl.lib添加到链接器输入中。
