Someone, please help me with Saturn C...

I am trying to compile a file (i read in an tutorial) that i just copyed and pasted. I saved it as main.c and objects

(also as the tutorial said), but when i try to compile it it says:

main.c:7: ´TV320x224´ undeclared (first use this function)

main.c:7: (each undeclared identifier is reported only once

main.c:7: for each function it appears in.)

make.exe: *** [main.o] error 1

It works to compile other programs.

Please help me. I really want it to work.
