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.
