title: use GPIO sysfs in Ubuntu 14.04 with kernel 3.14.1
body: <p>I am trying to get a viperboard USB GPIO board running on ubuntu.
  I already got a newer kernel, because I understood that the 3.13 kernel doesn't support the viperboard so well.</p>
  
  <p>What I want to do is to use the /sys/class/gpio sysfs interface for GPIO so I can develop raspberry pi projects on my PC and then use them
  on my RPi.</p>
  
  <p>My Problem - the /sys/class/gpio directory is missing.
  The config of the kernel shows:</p>
  
  <blockquote>
    <p>CONFIG_GPIO_SYSFS is not set</p>
  </blockquote>
  
  <p>Does this mean I have to compile a new kernel?</p>
