undefined reference to `sf::SoundBuffer::SoundBuffer()'

[Alfonso1]

I am using Windows XP and code::block

when I load some sample (for example the "sound" sample) and try to compile it, it geves me an error

undefined reference to `sf::SoundBuffer::SoundBuffer()'

what can i do?

Link the SFML libraries. But I have already told you that twice here.

Have you ever taken a look at the official tutorials? :roll:

[Alfonso1]

is these the official totorial?

Tutorial - Getting started - SFML and Code::Blocks (MinGW)
http://www.sfml-dev.org/tutorials/1.6/start-cb.php

yes I had read it, but I can't link the library

is these the official totorial?

Yes.

yes I had read it, but I can't link the library

If you tried at least to describe your problem in a meaningful way, we would be able to help you. But like this, it is really difficult. Why exactly can't you link the library? What doesn't work?

I dont know, when I try to compile it gives me these error.
