 Hi,

   I'm trying to build machinekit from the 2017-02-12 version.  I've 
 gone through the steps below, and at step 24 I encounter an error while 
 compiling emctask.cc.  I read somewhere that adding a swap space might 
 help, so I tried to add one, and it either didn't help, or I did it wrong. 
  
 In any case, can anyone tell me if the steps I've taken below are either 
 wrong, or if I'm missing any?

 Thanks,

 Jeff
 (PS.  I tried to download the most recent Jessie version and when 
 booting the three blue LEDs would light up, and the BBB would freeze, thus 
 I'm using the 02-12 version)

For the gerber to gcode conversion I find pcb2gcode works quite well with 
kicad:
pcb2gcode/pcb2gcode 
There is also a GUI for it:
https://github.com/pcb2gcode/pcb2gcodeGUI

This setup creates code for milling the outlines of the connections and 
only removes that.
