Ethernet Interface

The whole superloop concept isn't giving me any positive vibes...I installed Quartus 7.1, and Megacore IP library 7.1 and Nios 2 EDS 7.1, just to get the superloop socket server example to work. I followed the instructions in the attached word document to the letter. However, when I came to the stage of building the superloop socket server example...I got errors in the network_utilities.c file that it could not find the headers "ipport.h" and "tcpport.h"
