This command is trying to link rand.o with librand.a to make an executablecalled rand(.exe on Windows). This can't possibly be what you meant to do. 
Since every program must have a main() (or WinMain() for GUI programs),and rand.o does not, the linker complains.
You really should just  Google for a tutorial that explains how to compileprograms with gcc. The gcc manual (available at www.gnu.org) probablywon't help you with that.
