BACnet Stack Makefile - c

Question

I updated this post on 8/23 to reflect the working solution.
I'm working with the c BACnet Stack on sourceforge. http://sourceforge.net/projects/bacnet/
I'm trying to modify the demo server included in the library. The server does almost exactly what I want it to, except that I need to connect it to some other c programs that I wrote.
My problem right now is that I can't figure out how to add my own c programs into the demo server. There are several nested Makefiles in the demo. I've tried adding my file into these Makefiles, but the compiler (gcc) doesn't like it.
The latest error is:
No rule to make target ../../demo/object/test.o', needed bybacserv'. Stop.
I am not a c expert. I've been working with it my spare time for about a year. I understand the basics of a Makefile, but the Makefiles in this demo are apparently beyond me.
Is there anyone familiar with this library that might give me a little help?
Are there any better documentation than what is on the sourceforge website?
In this example I'm simply trying to add test.c to ai.c.

I would say that your test.o cannot be made by gcc. The Makefile does specify to create it, though :
.c.o:
${CC} -c ${CFLAGS} $*.c -o $#
I noticed that $(BACNET_OBJECT) in /demo/server/Makefile refers to the path /demo/object
You should try to add test.c there.
And i believe you don't need to add test.c in /lib/Makefile
Long time i didnt do any C, but didnt you forget to #include <stdio.h> for printf in test.c ?
