Programming attiny85 using eclipse

Hello! I want to control the digital output in attiny85. I use eclipse ide with the plugin avr. As a programmer I use avr pocket programmer. The text of the sketch:

#include "Arduino.h"

int pinNumber = 0;

void setup()
{
    pinMode(pinNumber, OUTPUT);
}

void loop()
{
    digitalWrite(pinNumber, HIGH);
    delay(1000);
    digitalWrite(pinNumber, LOW);
    delay(1000);
}

int main(void)
{
    init();
    setup();

    for (;;)
    {
        loop();
    }
    return 0;
}

I programmed the microcontroller, but there is no control pin. The voltage is always equal to 0V. If I control the digital output using DDRB and PORTB, then the output control works. I need your help.

Compile the program using the Arduino IDE. Use avr-objdump to disassemble the image. Compile the program using Eclipse. Use avr-objdump to disassemble the image. Compare the two dis-assemblies.
