Emacs assumes GNU Make, and GNU Make has much of the functionality of
Automake built-in. The Emacs build process uses Automake primarily
because Emacs uses some Gnulib code and Gnulib formerly required
Automake. Now that Gnulib no longer requires Automake, Emacs can
stop using Automake and this should simplify Emacs maintenance
in the future (Bug#26100). Although this patch may look long, most of
it is generated automatically: the changes to build-aux/config.guess,
build-aux/config.sub, build-aux/install-sh, and lib/gnulib.mk.in are
all done by admin/merge-gnulib.
* .gitignore: Remove build-aux/ar-lib, build-aux/compile,
build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
build-aux/install-sh, build-aux/missing, and lib/Makefile.in,
as they are no longer built by autogen.sh.
Add lib/gnulib.mk, as it is now built by 'configure'.
Remove nt/gnulib.mk, as it is no longer built by 'make'.
* INSTALL.REPO, README, admin/make-tarball.txt:
Remove mention of Automake.
* Makefile.in (AUTOCONF, AUTOMAKE, AUTOHEADER, ACLOCAL, lib)
(AUTOCONF_INPUTS, ACLOCAL_PATH, ACLOCAL_INPUTS)
($(srcdir)/aclocal.m4, AUTOMAKE_INPUTS)
($(srcdir)/lib/Makefile.in, $(srcdir)/nt/gnulib.mk, am--refresh):
Remove.
($(MAKEFILE_NAME)): Depend on lib/gnulib.mk.in.
($(srcdir)/configure, $(srcdir)/src/stamp-h.in)
($(srcdir)/src/config.in):
Use autogen.sh instead of doing it by hand.
* admin/merge-gnulib (AVOIDED_MODULES, avoided_flags)):
New vars, to simplify processing of avoided modules.
(GNULIB_TOOL_FLAGS): Move --avoid flags into AVOIDED_MODULES.
Add --gnu-make, and change makefile name to gnulib.mk.in.
Copy config.guess, config.sub, and install-sh too, since
Automake no longer does that for us.
* admin/notes/copyright:
* admin/update_autogen (genfiles):
Update list of files.
Remove hack for nt/gnulib.mk, a file that is no longer needed.
* autogen.sh (progs): Remove Automake.
(automake_min): Remove.
Build aclocal.m4 so that autoreconf need not use aclocal.
* build-aux/config.guess, build-aux/config.sub:
* build-aux/install-sh:
New files, copied from Gnulib. These are now updated by
admin/merge-gnulib instead by autogen.sh.
* configure.ac (AC_PROG_MAKE_SET, ACLOCAL_PATH, AM_CONDITIONAL):
Remove.
(AM_INIT_AUTOMAKE, AM_SILENT_RULES): Remove call.
(AC_PROG_CC_C_O): Call this instead of AM_PROG_CC_C_O.
(BUILDING_FOR_WINDOWSNT, HYBRID_MALLOC_LIB): Remove; no longer needed.
(--disable-silent-rules): New option, since Automake no longer
does this for us.
(AM_V, AM_DEFAULT_V): Set unconditionally, and do not bother
with AM_SUBST_NOTMAKE.
(AC_PROG_INSTALL): Add call.
(MAKEINFO): Do not bother with the 'missing' program.
(MAKEINFO, SYSTEM_TYPE): AC_SUBST.
(AC_CONFIG_FILES): Add Makefile, lib/gnulib.mk.
(SUBDIR_MAKEFILES): Remove duplication.
* lib/Makefile.am: Remove, replacing with:
* lib/Makefile.in: New file, with the old Makefile.am contents
and with the following changes:
(AUTOMAKE_OPTIONS, BUILT_SOURCES, CLEANFILES, EXTRA_DIST)
(MOSTLYCLEANDIRS, MOSTLYCLEANFILES, noinst_LIBRARIES, SUFFIXES)
(AM_CFLAGS, DEFAULT_INCLUDES, libegnu_a_SOURCES, libegnu_a_LIBADD)
(EXTRA_libegnu_a_SOURCES, libegnu_a_SHORTNAME, libegnu_a_CPPFLAGS):
Remove.
(VPATH, abs_top_builddir, top_builddir, top_srcdir, all, AM_V_AR)
(AM_V_CC, AM_V_GEN, AM_V_at, DEPDIR, DEPFLAGS, MKDEPDIR, SYSTEM_TYPE)
(libgnu.a, libegnu.a, ETAGS, $(ETAGS), tags, TAGS, clean)
(mostlyclean, distclean, bootstrap-clean, maintainer-clean):
New macros and rules, since Automake no longer does them.
Include ../nt/gnulib-cfg.mk if SYSTEM_TYPE is windows-nt,
instead of including ../nt/gnulib.mk if BUILDING_FOR_WINDOWS_NT.
Include dependency files if AUTO_DEPEND.
(ALL_CFLAGS, AUTOCONF_INPUTS, libgnu_a_OBJECTS, libegnu_a_OBJECTS):
New macros.
(bootstrap-clean): Depend on distclean, not maintainer-clean,
and remove gnulib.mk.
(AUTOCONF_INPUTS, $(top_srcdir)/configure, ../config.status, Makefile):
New macros and rules, copied from ../Makefile.in.
($(libegnu_a_OBJECTS), $(libgnu_a_OBJECTS)): Depend on BUILT_SOURCES.
(.c.o, e-%.o): New generic rules.
* lib/gnulib.mk: Remove.
* lib/gnulib.mk.in: New file, which is built by autogen.sh
and contains much of what used to be in lib/gnulib.mk.
* m4/gnulib-common.m4: Copy from gnulib.
* make-dist: Do not distribute build-aux/compile, build-aux/depcomp,
build-aux/missing, build-aux/ar-lib, lib/Makefile.am, nt/gnulib.mk,
nt/gnulib-modules-to-delete.cfg. Distribute lib/Makefile.in,
lib/gnulib.mk.in, and nt/gnulib-cfg.mk instead.
* nt/Makefile.in (AM_V_GEN, am__v_GEN_, am__v_GEN_0)
(am__v_GEN_1, ${srcdir}/gnulib.mk): Remove.
* nt/gnulib-cfg.mk: New file, which supersedes ...
* nt/gnulib-modules-to-delete.cfg: ... this file, which is removed.
* src/Makefile.in (ACLOCAL_INPUTS): Remove.
(AUTOCONF_INPUTS): Merge ACLOCAL_INPUTS into it.

This directory tree holds version 26.0.50 of GNU Emacs, the extensible,
|
||
customizable, self-documenting real-time display editor.
|
||
|
||
The file INSTALL in this directory says how to build and install GNU
|
||
Emacs on various systems, once you have unpacked or checked out the
|
||
entire Emacs file tree.
|
||
|
||
See the file etc/NEWS for information on new features and other
|
||
user-visible changes in recent versions of Emacs.
|
||
|
||
The file etc/PROBLEMS contains information on many common problems that
|
||
occur in building, installing and running Emacs.
|
||
|
||
The file CONTRIBUTE contains information on contributing to Emacs as a
|
||
developer.
|
||
|
||
You may encounter bugs in this release. If you do, please report
|
||
them; your bug reports are valuable contributions to the FSF, since
|
||
they allow us to notice and fix problems on machines we don't have, or
|
||
in code we don't use often. Please send bug reports to the mailing
|
||
list bug-gnu-emacs@gnu.org. If possible, use M-x report-emacs-bug.
|
||
|
||
See the "Bugs" section of the Emacs manual for more information on how
|
||
to report bugs. (The file 'BUGS' in this directory explains how you
|
||
can find and read that section using the Info files that come with
|
||
Emacs.) For a list of mailing lists related to Emacs, see
|
||
<http://savannah.gnu.org/mail/?group=emacs>. For the complete
|
||
list of GNU mailing lists, see <http://lists.gnu.org/>.
|
||
|
||
The 'etc' subdirectory contains several other files, named in capital
|
||
letters, which you might consider looking at when installing GNU
|
||
Emacs.
|
||
|
||
The file 'configure' is a shell script to acclimate Emacs to the
|
||
oddities of your processor and operating system. It creates the file
|
||
'Makefile' (a script for the 'make' program), which automates the
|
||
process of building and installing Emacs. See INSTALL for more
|
||
detailed information.
|
||
|
||
The file 'configure.ac' is the input used by the autoconf program to
|
||
construct the 'configure' script.
|
||
|
||
The shell script 'autogen.sh' generates 'configure' and other files by
|
||
running Autoconf, which in turn uses GNU m4. If you want to use it,
|
||
you will need to install recent versions of these build tools. This
|
||
should be needed only if you edit files like 'configure.ac' that
|
||
specify Emacs's autobuild procedure.
|
||
|
||
The file 'Makefile.in' is a template used by 'configure' to create
|
||
'Makefile'.
|
||
|
||
The file 'make-dist' is a shell script to build a distribution tar
|
||
file from the current Emacs tree, containing only those files
|
||
appropriate for distribution. If you make extensive changes to Emacs,
|
||
this script will help you distribute your version to others.
|
||
|
||
There are several subdirectories:
|
||
|
||
'src' holds the C code for Emacs (the Emacs Lisp interpreter and
|
||
its primitives, the redisplay code, and some basic editing
|
||
functions).
|
||
'lisp' holds the Emacs Lisp code for Emacs (most everything else).
|
||
'leim' holds the original source files for the generated files
|
||
in lisp/leim. These form the library of Emacs input methods,
|
||
required to type international characters that can't be
|
||
directly produced by your keyboard.
|
||
'lib' holds source code for libraries used by Emacs and its utilities
|
||
'lib-src' holds the source code for some utility programs for use by or
|
||
with Emacs, like movemail and etags.
|
||
'etc' holds miscellaneous architecture-independent data files Emacs
|
||
uses, like the tutorial text and tool bar images.
|
||
The contents of the 'lisp', 'leim', 'info', and 'doc'
|
||
subdirectories are architecture-independent too.
|
||
'info' holds the Info documentation tree for Emacs.
|
||
'doc/emacs' holds the source code for the Emacs Manual. If you modify the
|
||
manual sources, you will need the 'makeinfo' program to produce
|
||
an updated manual. 'makeinfo' is part of the GNU Texinfo
|
||
package; you need a suitably recent version of Texinfo.
|
||
'doc/lispref' holds the source code for the Emacs Lisp reference manual.
|
||
'doc/lispintro' holds the source code for the Introduction to Programming
|
||
in Emacs Lisp manual.
|
||
'msdos' holds configuration files for compiling Emacs under MS-DOS.
|
||
'nextstep' holds instructions and some other files for compiling the
|
||
Nextstep port of Emacs, for GNUstep and macOS Cocoa.
|
||
'nt' holds code and documentation for building Emacs on MS-Windows.
|
||
'test' holds tests for various aspects of Emacs's functionality.
|
||
|
||
Building Emacs on non-Posix platforms requires tools that aren't part
|
||
of the standard distribution of the OS. The platform-specific README
|
||
files and installation instructions should list the required tools.
