I am trying to compile the Linux Ethernet SDK, but I'm having some trouble. I was able to do this about 18 months ago, and I remember having a little bit of trouble back then, too. I had some help from another gentleman from the forums at Automation Direct through direct e-mail, but figured I'd post this here so whatever the solution may be is available to anyone.
I was able to work around this issue by uploading the source to a directory to one of my web host's servers and compiling it there. I then copied the files to my server and ran make install.

The computer this program will be running on has two network cards. One is connected to a 5-port switch on a cable modem, and the other is connected to my LAN. There is a PLC on the "internet" side of the server, and my network has about 10 PLC's on it. I have a test program that was given to me that searches the network for ECOM's and lists them. The program is only searching for devices on the one interface. Is there something I can do to make it search the other?
