Hi Igor,
I am trying to add the files you sent.  However, I can see now that
pps-generator-gpio.c includes corresponding header file, and you
forgot so send it, so the compilation fails (fatal error:
linux/pps-generator-gpio.h: No such file or directory).

Do you have this file at your disposal?

BR,
Drasko
