Normally, modprobe does not require any headers.

About the link you provided : if I understand well, I need a dev machine where I install everything an compile again then I can copy, right?
Yes, your understanding is correct. The commands from my instructions should be run on a development machine. The installation of the development machine is described at
this link. The main advantage of this approach is that compilation runs much faster than on Red Pitaya.

Is there anyway to do it directly on the RP (if this involves an 40GB+ SD card, it is not an option right?
It'll take some time (hours). Make sure that your Red Pitaya is properly cooled during this time. Without an active cooling, it'll most probably overheat during the compilation.
You can try the following commands to build modules on Red Pitaya:

(I guess it has something to do with the distribution used, but I missed something in the provided doc...) thanks
