SOS !! unrecognized option '-pu' - what is this ??!!

dear all

Keil is driving me nuts, i just opened an example and when i compile the project an error appears which is

unrecognized option '-pu'

what should i do?

  • "i just opened an example"

    What example?
    Did it come with any instructions on preparations that you have to make before opening it?

    "an error appears which is unrecognized option '-pu'"

    What tool productes that error?
    For what file(s)?

    You don't have any spaces anywhere in any of your paths, do you...?

    "what should i do?"

    Stop panicking, and think logically!
