[Mac-emacs-users] Emacs 21.2 on Darwin: the ctrl-G crash in -nw still exists, old patch still works
|
From: Marc-Antoine P. <map...@ac...> - 2002-05-26 16:05:50
|
The title says it. I rebuilt the new emacs from CVS today (Thanks
Andrew!) and I noticed that, when I try to use emacs via a terminal
(option -nw) and use ctrl-G, emacs crashes. The content of the old patch
that was posted a while ago still solves this problem.
Applying the patch led to a few errors during patch, which all
correspond to the patche's content having been otherwise integrated in
the source. Ignore those.
Another detail:
The patch adds the line
#define HAVE_ALLOCA
in src/s/darwin.h
This causes a warning during compilation, as HAVE_ALLOCA is now defined
in src/config.h.
I removed it from darwin.h
The resulting patch file looks something like this:
Tell me if I've made a mistake somewhere, I've been doing this somewhat
blindly...
