JIT Emacs

JIT Emacs

[Emanuel Berg]

I just downloaded and built the JIT Emacs.
Easy and it worked great. But I didn't install
it because I wanted to try it out first.

However trying to bring in my own Elisp was
another matter. Compilation brought literally
hundreds of errors and warnings, files not
found, functions not defined, etc. etc.

So is there a method to do this, which, while
not solving every single problem at once, at
least will, as far as possible, minimize the
transition problem?

TIA

I don't think I understand the problem you are describing.  Using
Emacs with JIT doesn't require recompiling any Lisp files.

Also, what kinds of errors and warnings did you see?

Perhaps the version of your "regular" Emacs and your freshly
compiled JIT Emacs are so different that the .elc or the
Lisp libraries aren't quite compatible?

Starting JIT without recompiling runs on an
error immediately, commenting that away,
another error, an so on.

To answer Tomas' question, which I thought
about also, I'm currently on GNU Emacs 24.4.1
from the distro's repo. JIT is 27.0.50.

I made a branch in the Makefile [1]

    jit-emacs=0

    ifeq ($(jit-emacs),1)
       emacs=/home/incal/emacs/emacs-feature/libjit/src/emacs
    else
       emacs=emacs
    endif

with jit-emacs as 0, not a single warning
or error. With jit-emacs as 1, well to answer
your question...

(It seems Emacs-w3m, a third party piece of

a lesser extent ERC. The "obsolete" stuff I can
