jit-compile: Not a byte-compiled function

jit-compile: Not a byte-compiled function

[Óscar Fuentes]

I'm trying the libjit branch but I'm stuck with the above error thrown
from jit-compile. For instance:

$ emacs -Q

;; Eval in *scratch*:

(defun foo ()
  (message "hi!"))

(byte-compile 'foo)
(jit-compile 'foo)


What I'm missing?

The function has to be compiled with lexical-binding = t.

Thanks, but evaluating this sequence in *scratch* :

(setq lexical-binding t)
(defun foo ()
  (message "hi"))
(byte-compile 'foo)
(jit-compile 'foo)

still produces the error. Same with a function that is defined on a
source file that contains lexical-binding: t as file-local variable:

(jit-compile 'avy--style-fn)

Sorry, I misremembered this earlier.  I built the libjit branch again
and tried it.  jit-compile takes a compiled object:

  if (!COMPILEDP (func))                                                                                                                                                                                           
    error ("Not a byte-compiled function");                                                                                                                                                                        

So you need

(jit-compile (symbol-function 'foo))

The compiled code is stored into the bytecode vector.

Thanks, this method works.
