Erro Compiling - Serial port

[jorgan202]

Hi, I am very new to this and have tried to look for the error. Please can someone point me in the right direction withe the following error? :
Arduino: 1.6.1 (Windows 7), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"
In file included from Marlin.h:22:0,
from cardreader.cpp:1:
Configuration.h:41:2: error: 'SERIAL_PORT' does not name a type
SERIAL_PORT selects which serial port should be used for communication with the host.

Error compiling.

I'm not sure I understand what you try exactly. This package is meant to be used with ros on Ubuntu. We do not depend on any serial port with this package.
