Works On XP, But Not 98

[hatflyer]

I compiled my program on WIndows XP, and the executable works fine.
But when I try to run the executable on a W98, the resulting error
says something like the executable is linked to missing export
mfc.DLL.688

Do I have to compile my program on a W98 machine to yield a workable
program on W98? Do I have to link .dll files?

I'm just a newby, so if any linking is needed, I'd appreciate learning how to.

Thanks,

Matt
