Error in C compilation when rubex method is recursive

[shaunakpp]

Consider a simple example of printing sum of n Fibonacci numbers.

# fibonacci.rubex
class Fibonacci
  def compute(int n)
    if n == 0 || n == 1
      return n
    end
    return compute(n - 1) + compute(n - 2)
  end
end

running rubex fibonacci.rubex successfully generates the extconf.rb, Makefile and fibonacci.c files. But, on running make, I got the following errors:

It would be awesome if recursion is supported in rubex, as recursion often helps in writing concise programs.
