Cant Figure Out This Darn Linker

[Bluesun159]

g++: -lobjc: linker input file unused since linking not done

Well, the message is above,

all I did was declare a few variables and some output and input, but I can't run the program and have it show any of it,

[gcn_zelda]

show us the program

What options were you using with g++?

I don't know about g++, I'm using Dev C++ and my book doesn't talk about g++. I think it might be my complier, because when I run the executable, all that shows up is the system("PAUSE").

[Bluesun159]

SEEMS YOU'RE RIGHT, that could be why it's not working...O_o

[Bluesun159]

I changed all of them, but it's still not working.
I DON"T GET IT :S
