Help compiling an application

I need some help... I have some Epson Point Of Sale printers that I need to manage some advanced settings on and while there is a windows version of the program the only thing I could find from Epson for Mac was source code.. I don't understand why they would release that and not the actual app but either way I need to try and make it work since I don't have access to a windows computer.

I am attaching the code, I tried putting it in xcode and hitting run but it comes up with a couple errors and that is way beyond me.

If someone could take a look at this and just see if they could get it compiled for me I would greatly appreciate it.

Edit: I guess what is included in there is a sample app and that package is meant to be for incorporating into your applications.... that sample app may be functional though and if it is that would be great.
