Software size is too big

dsl, how can i use the unix printf then?

I made the following changes and the code size went down from 28k to 13kbytes (A NORMAL PRINTF)

template BSP/syslib:

- uncheck Support C++ em properties->C/C++ Build do BSP Template

- check Lightweight device driver no BSP Editor

- check Reduced device drivers no BSP Editor

- uncheck enable_clean_exit no BSP Editor

- uncheck enable_exit no BSP Editor

- configure optimize level to Size on properties->C/C++ Build do BSP Template

- configure Debug level to none on properties->C/C++ Build do BSP Template

Software:

- configure optimize level to Size em properties->C/C++ Build do BSP Template

- configure Debug level to none em properties->C/C++ Build do BSP Template

IF I CHANGE the code to this

#include "sys/alt_stdio.h"
//#include <stdio.h>
int main()
{
  //printf("Hello from Nios II!\n");
  alt_putstr("Hello from Nios II!\n");
  return 0;
}

the size goes to 600bytes
