Re: GCC Fails to Recognize Parameters 2 Months Ago by rproffitt Here's another problem. When we change the OS not only must we setup the compiler, environment and such but sometimes an OS API could be deprecated or removed. You made mention of a possible OS change so that's a possibility. You obtained this code from somewhere. Go back there and see if they updated it for your new OS.
