Il a l'air de manquer
#include "xgpio_l.h"
#include "xutil.h"

Es-tu sur que la fonction Print (avec un P majuscule existe ?

De plus "Do / while" s'écrit "do / while" avec un 'd' minuscule

Merci beaucoooooooooooooup ça marcher

La fonction XGpio_mGetDataReg fait parti du kernel. Comment tu fais pour appeler une fonction du kernel depuis un programme en userspace ?!?

Je me trompe pas, c'est bien un simple executable que tu fais et pas un module, hein ?

Je voudrais voir ton makefile et en particulier tes options de link... Qq chose m'echappe. Qd j'essaye de compiler une version simplifiée, tout ce que j'obtient c'est:
