libtins | High-level , multiplatform C++ network packet sniffing | Learning library

This is the output of the SDK when it tries to link my project:

I'm getting undefined reference to dlsym@@GLIBC_2.2.5 even after linking it before and after the libraries. However in the linking output it appears that it's linking just before, but linking before all libraries should work, I guess.

I have a uint8_t* buffer which I get by doing buf.data(). It's a buffer of an IP packet.

I want to change the source address and recalculate the checksum, so I recreated the packet in libtins by doing what you see below:

I was trying to make a program to sniff packets and went to libtins

If you are using a static build of libtins on Windows, then you have link your application with tins.lib. You also need to add this macro definition to your project: TINS_STATIC

What does it mean? It even does not have a value. Can some one help me how to add this in visual studio?

Does it mean something like

I'm working on an small UDP traffic sniffing example using libtins. Everything worked until I started encapsulating everythin into a class. Acording the tutorial (loop sniffing section), the snifer_loop takes a template functor as an argument, and:

The call to Sniffer::sniff_loop will make the sniffer start processing packets. The functor will be called using each processed packet as its argument. If at some point, you want to stop sniffing, then your functor should return false. Otherwise return true and the Sniffer object will keep looping.

The functor object will be copy constructed, so it must implement copy semantics. There is a helper template function which takes a pointer to an object of a template parameter type, and a member function, and returns a HandlerProxy. That object implements the required operator, in which it forwards the call to the member function pointer provided, using the object pointer given:

Everything works if I use PDU data type, or if I use Packet type with an external function, but once I use Packet type with a method, I get a compiler error:

I took a look at libtins and at the Examples I found the ARP Monitor example. The Code of the Example is this here:

Trying to set up libtins on windows. Im relatively new to Visual studio and most of the documentation on the matter was for older versions. I was able to get the include files set up with the project but linking the .lib's was problematic and i cant seem to configure it properly. The properties menu seems pretty convoluted as im used to doing most things compiler related configurations from a command line.
