Hello everyone ! Is there a guide out there (here or on the net), that provide step-by-step easy to understand explanantions on how to build a wallet on a Raspberry Pi 2 ?

What kind of wallet? Different wallets are compiled differently. Are you talking about the bitcoin-qt fork for altcoins? That has the instructions inside the source on github, usually called build-unix which will help you build things on linux and thus the raspberry pi.

Yes, I am talking about that. Thank you I'll take a look to the sources on GitHub, but if there is nothing, what do I have to do ?

Generally you can use Bitcoin's build docs at: https://github.com/bitcoin/bitcoin/blob/master/doc/build-unix.md to help you since most coins are forks of Bitcoin. However some of the dependencies might not work since altcoins may add or remove dependencies and Bitcoin changes its dependencies as it evolves.

I personally use buildroot https://buildroot.org/ to compile for ARM devices (including the pi) since compiling on the device itself can be horridly slow. I haven't written up a guide, but it does vary greatly on the dependencies used.  It is usually best to consult the README for whatever coin you are building so that you can prepare your environment accordingly.

Good luck.
