How to compile tictactoe widget example in tutorial

[donn <donn ingle gmail com>]

Hi,
I can't figure out how to compile the sample code at:
http://man.chinaunix.net/develop/GTK+/tutorial/a2903.html#SEC-TICTACTOE

There seems to be no information beyond the usual gcc for compiling a 
simple .c app (like Hello.c).

I get this:
$ gcc -Wall -g tictactoe.c -o ttt `pkg-config --cflags --libs gtk+-2.0`
/usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crt1.o: In function 
`_start':
/build/buildd/eglibc-2.10.1/csu/../sysdeps/i386/elf/start.S:115: 
undefined reference to `main'
collect2: ld returned 1 exit status

And:
$ gcc -Wall -g test_tictactoe.c -o ttt `pkg-config --cflags --libs gtk+-2.0`
/tmp/cccS33ns.o: In function `win':
/home/donn/Projects/cing/gtk_tuts/test_tictactoe.c:9: undefined 
reference to `tictactoe_get_type'
/home/donn/Projects/cing/gtk_tuts/test_tictactoe.c:9: undefined 
reference to `tictactoe_clear'
/tmp/cccS33ns.o: In function `main':
/home/donn/Projects/cing/gtk_tuts/test_tictactoe.c:29: undefined 
reference to `tictactoe_new'
collect2: ld returned 1 exit status

Which is all Martian to me ;) Is this a bug in the tutorials, or a 
compile thing?

Any clues?
