[racket] scheme code in assembly level

I took a look.
When running test I find:

line 77 of decompiler.rkt:
(define on_demand_jit_code (get-ffi-obj "scheme_on_demand_jit_code" #f _pointer))
error: decompiler.rkt:77:0: ffi-obj: couldn't get "scheme_on_demand_jit_code" from #f (No se encontr  el proceso especificado.; errno=127)
(cannot find the specified process)

What do I wrong?
Thanks, Jos
