NIOS2 MMU uCLinux + LEDs

Hi

I'm trying to use LEDs on my DE2-70 board. When I add LED NIOS2 driver in menuconfig of uCLinux I get error during compilation.

/home/lukasz/workspace/nios2-linux/linux-2.6/arch/nios2/drivers/pio.c: In function 'pio_led_init':

How I have to define in nios.h my LEDs and how name it in SOPC to work with them?
