我现在已经在这几个小时了(而且就在今天)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,因此我尝试将curlpp添加到我的Code :: Blocks项目中。
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包含文件夹 curl-7.22.0 \ include 添加到项目中,再试一次。

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,并且它位于 C:\ Program Files(x86)\ Microsoft SDKs \ Windows \ v7.0A \ Lib 中,但是将其添加到libraries文件夹在VS2005项目中似乎没有做任何事情。
我只是在忘记这一切......这应该是怎么回事?我认为它会如此简单:
但不幸的是,这似乎并不那么容易。
更新
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
但是在 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?但它一定是我做的奇怪事情,因为有人会注意到它!
UPDATE2 好的,我从头开始,发现我还必须从windows SDK添加 includes 文件夹。这照顾了无法打开包含文件:'winsock2.h'错误。但现在我收到了其他一些错误:

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”中正如你在上面看到的那样我包含的文件夹,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(没有10的选项)希望会工作,但这是我打开在VS2010中创建的解决方案文件时得到的结果:

甚至从未创建过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。
答案 0 :(得分:0)
我看到你正在将curlpp编译成动态库。那是你想要的吗?您应该将 libcurl.lib 添加到链接器输入。
