error in building a project in software eclipse

I wrote the code to perform read and write operation of a register in nios-ii SBT Eclipse.While building a project,one error occuring for me.I didn't know to correct the error.I want to know about the error and how to correct it.

my code is:# include "sys/alt_stdio.h"# include "system.h"# include "io.h"# define OFFSET 1# define DATA 0x000010# define BASE 0X00005000

void init()

{

while(1)

{

IOWR_8DIRECT(BASE,OFFSET,DATA);

alt_printf("iregport=%x\n",IORD_8DIRECT(BASE,OFFSET));

}

}

alt_main()

{

alt_putstr("hello from nios-ii!\n");

init();

while(1);

return 0;

}

error is:
