From 3f8a2dd54edab7d30fa4b218f42ea36d7f36560e Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Wed, 22 Nov 2017 21:07:29 -0800 Subject: port elisp-compilation support to emacs-23.1 and newer In May of 2017, emacs.master support for using the long-deprecated byte-compile-dest-file function was removed, and that removal broke automake's elisp-compiling rule for any .el file not in the current directory. In emacs-23.1 (July 2009) byte-compile-dest-file-function became the recommended way to adjust the byte-compiler's destination. The removed functionality has been restored for Emacs-26, albeit with dissuasive diagnostics warning about the imminent removal of this functionality. It will be removed in Emacs-27. * lib/am/lisp.am (.el.elc): Use byte-compile-dest-file-function, rather than byte-compile-dest-file. Also, use "-f batch-byte-compile '$<'" rather than open-coding it, as suggested by Glenn Morris. * t/lisp-readonly-srcdir.sh: New file, to test for the above. * t/list-of-tests.mk (handwritten_TESTS): Add it. * NEWS (Bugs fixed): Mention this problem. --- t/lisp-readonly-srcdir.sh | 46 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 t/lisp-readonly-srcdir.sh (limited to 't/lisp-readonly-srcdir.sh') diff --git a/t/lisp-readonly-srcdir.sh b/t/lisp-readonly-srcdir.sh new file mode 100644 index 000000000..38b866404 --- /dev/null +++ b/t/lisp-readonly-srcdir.sh @@ -0,0 +1,46 @@ +#! /bin/sh +# Copyright (C) 2017 Free Software Foundation, Inc. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2, or (at your option) +# any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
