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: Â´TV320x224Â´ 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.
