It may sound ridiculous , but i am getting errors while running the socket example programs like

cannot

well there are many and i do understand there is some small linking error .
i would be glad if u could help me out.

It's not about linking, you probably just forgot to include <SFML/Network.hpp>.

Well i have already included that , but still i do get error messages in here.

These ones are linker errors

Did you link to sfml-network?

[Mindiell]

Linking console executable: bin\Debug\sockets.exe

Let's try smfl-network-d

[rahul8590]

well that linking worked  . kudos to you

But i am unable to understand its working. if i compile that part of code and run it , i am getting one terminal (assuming server) . Now how do i get the client server communicating with each other .
