Anet A8, cannot install Firmware

Hi,
i have a Anet A8 Printer and i would like to install the Repetier-Firmware because i plan to update the Printer with AutoLeveling.
I use the ARDUINO 1.8.1, my Mainboard ist this when i upload the Firmware i become this Massage:
 
 Arduino: 1.8.1 (Linux), Board: "Arduino/Genuino Uno"
.

sketch/fastio.h:17:30: note: in definition of macro 'MASK'
  #define  MASK(PIN)    (1 << PIN)

         WRITE(Y_STEP_PIN,!START_STEP_WITH_HIGH);
         ^
exit status 1
