Why the error?

itoa isn't standard and doesn't appear to be included on OS X (there isn't a man page, as there is for atoi)

See http://stackoverflow.com/questions/190229/where-is-the-itoa-function-in-linux#190235 for similar issues on linux. The suggestions should work just as well on OS X.

Thanks. Used sprintf instead of itoa.
