Failing to compile curlpp

Question

I've been on this for a few hours now (and that's just today) so I could really use some help. I always code in a Windows environment so I am trying to add curlpp to my Code::Blocks project.

1. I downloaded curl-7.22.0-devel-mingw32 and added all those libraries to Code::Blocks project.
2. I downloaded curl-7.22.0 and compiled it using vc6curl.dsw which made libcurl.lib, added that to Code::Blocks project.
3. Downloaded curlpp-0.7.3
4. Added MinGW\lib\libwsock32.a to Code::Blocks project.
5. Added the following directories to the project: curlpp-0.7.3\include and curl-7.22.0\include

But I get a lot of "undefined reference" errors, so I'm guessing that means curlpp needs compiling too. It contains a VC8 project, so I downloaded Visual C++ 2005 Express and installed.

First error I get when opening the project is that the examples couldn't be loaded. Not really a problem, I guess. Trying to build the project right away, gives the error "Cannot open include file: 'curl/curl.h'" so I add the cURL includes folder curl-7.22.0\include to the project and try again.

Erorr upon error upon error, it's driving me nuts. Googeling that one doesn't really help either. I found some forum posts saying WS2_32.Lib had to be added, and that's in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib but adding that to the libraries folder in the VS2005 project doesn't seem to do anything.

I'm just losing track of it all.. how is this supposed to go? I thought it would be as simple as:

1. Compile curl
2. Compile curlpp
3. Profit!

But unfortunately it doesn't seem to be that easy.

UPDATE

Oh yeah, I forgot, initially I also got these errors:

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

But in src\curlpp there are:

Info.cpp
Options.cpp

So I just copied them and renamed the copies to

Info2.cpp
Option.cpp

And in src\utilspp there are

LifetimeLibrary.cpp
PrivateMembers.cpp

So I just made a folder "singleton" there and copied the files in there.

It's as if curlpp is.. broken? But it must be something weird I am doing because someone would have noticed!

UPDATE2 Ok I started from scratch and figured out that I also had to add the includes folder from the windows SDK. This took care of the Cannot open include file: 'winsock2.h' errors. But now I'm getting a buttload of other errors:

Will this ever end?

Additional Libraries now looks like this:

"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"

And the includes:

"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)"

What is BOOST PATH?

And also, to get rid of the "libcurl.lib not found" error, I opened the project I found in curl-7.22.0 and compiled it, but that means libcurl.lib is in the "lib\Debug" folder which I included as you can see above, did I do that correctly?

UPDATE3:

I noticed a file called create-vc-solution.bat so, after downloading "sed" for windows, I tried creating a vc solution for VS9 (There was no option for 10) hoping that would work, but here's what I get when I open the solution file that creates in VS2010:

curlpp.examples.VC9.vcproj and curlpp.VC9.vcproj were never even created. Has curlpp been tested at all? By anyone? I'm starting to think this isn't even my fault anymore.

Answer 1

I see you are compiling curlpp into dynamic library. Is that what you wanted? And you should add libcurl.lib to your linker input.
