I am getting the following error when i am compiling the code by selecting the board as attiny85, and if i compile the same code by selecting board as arduino nano ,i am getting no error. please help

[kamaluddin786]

Code :

#include <IRremote.h>

IRrecv irrecv(0);
decode_results results;

int lig1 = 1;
int lig2 = 2;
int lig3 = 3;
int lig4 = 4;

int flag1 = 0;
int flag2 = 0;
int flag3 = 0;
int flag4 = 0;

unsigned int value;

void setup() {
irrecv.enableIRIn();

pinMode(lig1, OUTPUT);
pinMode(lig2, OUTPUT);
pinMode(lig3, OUTPUT);
pinMode(lig4, OUTPUT);

}

void loop() {
if (irrecv.decode(&results)) {
value = results.value;
irrecv.resume();

if (results.value == 0x1FE50AF) {flag1 = !flag1; digitalWrite(lig1, flag1 ? HIGH : LOW); value =0; }
if (results.value == 0x1FED827) {flag2 = !flag2; digitalWrite(lig2, flag2 ? HIGH : LOW); value =0; }
if (results.value == 0x1FEF807) {flag3 = !flag3; digitalWrite(lig3, flag3 ? HIGH : LOW); value =0; }
if (results.value == 0x1FE30CF) {flag4 = !flag4; digitalWrite(lig4, flag4 ? HIGH : LOW); value =0; }
if (results.value == 0x1FE48B7)
{digitalWrite(lig1 , LOW);
digitalWrite(lig2, LOW);
digitalWrite(lig3 , LOW);
digitalWrite(lig4 , LOW);

}    

} }
