Kaleidoscope code example error

Dear all,

Good day to you. I was trying to subject some sample input code to Kaleidoscope code (given in https://llvm.org/docs/tutorial/MyFirstLanguageFrontend/index.html). However, as I subject the following code segment (given in https://llvm.org/docs/tutorial/MyFirstLanguageFrontend/LangImpl01.html) to the kaleidoscope executable

# Compute the x'th fibonacci number.
def fib(x)
  if x < 3 then
    1
  else
    fib(x-1)+fib(x-2)

# This expression will compute the 40th number.
fib(40)


the following errors are shown.

> > Error: Unknown variable name
> Error: Unknown variable name
> Error: Unknown variable name
> Read top-level expression:
define double @__anon_expr() {
entry:
  ret double 1.000000e+00
}

> Error: Unknown variable name
> Error: Unknown function referenced
Error: Unknown function referenced
> ; ModuleID = 'my cool jit'
source_filename = "my cool jit"


Can somebody kindly help ? 


Thanks a lot.

Perhaps you're trying to run that fib example in noe of the early
chapters (like chapter 1) - it's only going to work once you're a few
chapters in - I think at least around chapter 5, which provides
control flow ('if'/'else').

Thank you. I understood the mistake.
