Looks like you included the headers but didn't included in the project the "netlink.lib" (or whatever you named it in the static library project).
To use the library:
1- First create a project (static library) and include the sources of the "src" folder to compile and include "include" folder in headers path. Building it you get a lib file.
2- Use the headers of the "include" folder in headers path and also link against the lib file you created in the previous step to use the library in your project.
Can you confirm me if that was the cause?

Hi,
Thanks for your responsde.
Indeed, I didnt realize that I have to build a static lib first.
Let me try, and I will tell you

I program in Code :: Blocks IDE and put my archive project:
I have found where the problem is. You have modified library source files: for example in socket.h commenting
#include "netlink/core.h"
replacing it for
#include "socket.h"
(I don't know why).
I assume you have changed the includes instructions inside the sources of the library because you had problems making the compiler find them but you only have to add the include folder in the search path of the compiler to make it find them rather to modify the code of the library (as this leads to errors).
So what I suggest you is:
* Do not modify the source code of the library.
* Add include folder (as it is in the library package) to the search path of the compiler (in codeblocks go to project -> build options -> search directories -> compiler -> add)
I also would suggest you to build the library as static library instead of including all the sources files each time but this is totally up to you.
Please let me know if this solved your problem.
Regards.

Hi,
As for the version 1.0.0-pre3 Mingw is not supported and the library doesn't work for this compiler.
For windows platform is officially supported and tested Visual C++ 2008 Express Edition (you can download it for free). Any further version (as VC++ 2010) should be fine.
The compilers supported and tested are:
Windows: VC++ 2008+
OSX: g++
Linux: g++, intel compiler
I hope this helps.
Regards.
