title: recipe for target 'main.o' failed, Atmel Studio
body: <p>I'm getting the error: recipe for target main.o failed. I'm currently programming for the ATmega 168BPB board, trying to run the following simple program: </p>
  
  <pre><code>int main(void)
  {
      DDRB = 0xFF;
      PORTB = 1 &lt;&lt; PORTB5;
  
      while (1) 
      {
      }
  }
  </code></pre>
  
  <p>to just get the built-in LED to turn on.
  Has anyone had any experience with this problem and/or knows how to solve it?</p>
