Change `configure' to a mixture of custom code and autoconf stuff.
autoconf can't derive all the information we need, but we'd really
like to be able to take advantage of some of its tests, and its
file-editing facilities.
* configure.in: Renamed from configure.
Quote the sections of shell script we want copied literally to
the configure script.
(compile): Initialize this to make the autoconf macros' code happy.
Use AC_PROG_CC, AC_CONST, and AC_RETSIGTYPE instead of writing out
code to do their jobs.
Use autoconf to produce Makefile and src/config.h.
Remove the Makefile-style comment that autoconf places at the top
of src/config.h.
(config_h_opts): Removed - no longer necessary.
* Makefile.in (configname): Renamed to configuration.
(CONFIG_CFLAGS): Renamed to DEFS.
(CC, DEFS, C_SWITCH_SYSTEM, version, configuration): Adjusted to
get values via autoload @cookies@.
(libsrc_libs): Get this from autoconf. We used to do nothing
about this.
(${SUBDIR}): Pass DEFS to submakes instead of CONFIG_CFLAGS.
* Makefile.in (src/paths.h, lib-src/Makefile, src/Makefile): Don't
echo the move-if-change command.
C_SWITCH_SYSTEM from the configuration files.
* configure: Extract C_SWITCH_SYSTEM from the machine and
system-dependent files, and save it in the top-level Makefile.
* Makefile.in (C_SWITCH_SYSTEM): New flag for configure to edit.
(lib-src/Makefile): Edit C_SWITCH_SYSTEM into lib-src/Makefile.
CFLAGS.
* Makefile.in (locallisppath): Make this default to
${datadir}/emacs/site-lisp, instead of
${datadir}/emacs/local-lisp. ${datadir} and ${statedir} are often
the same thing, and local-lisp causes completion conflicts with
lock.
(lisppath): Add ${externallispdir} to this.
* INSTALL: Adjust installation directions.
* Makefile.in (externallispdir): New variable, to say where to
install the externally-maintained lisp files.
(COPYDIR, COPYDESTS): Copy the external lisp directory just like
the others.
* INSTALL: Describe external-lisp and the new externallispdir
variable.
${infodir} from these variables; we have written out explicit code
to install the info files.
* Makefile.in: Some makes can't handle comments in the middle of
commands; move them to before the whole rule.
now. Change references.
* Makefile.in: Adjust `install.mumble' targets to install
`src/emacs', not `src/xemacs'.
* Makefile.in (install, install.sysv, install.xenix, install.aix):
Don't try to copy the info files if there aren't any; the
unexpanded globbing pattern disappoints `install'. Ignore the
return status of that command.
Install the info files in ${infodir}. Install the executable
under both `emacs' and `emacs-VERSION'.
* Makefile.in: Doc fix.
* Makefile.in (exec_prefix): New variable, as per latest version
of coding standards.
(bindir, libdir): Use it, instead of `prefix'.
(lib-src/Makefile): Edit value of exec_prefix into lib-src/Makefile.
* Makefile.in (mandir): Make the default value for this depend on
$(prefix).
* Makefile.in (datadir, statedir, libdir): Make these all default
to ${prefix}/lib.
(lispdir, locallisppath, etcdir, lockdir, archlibdir): Adjusted
to compensate.
* Makefile.in (install, install.sysv, install.xenix, install.aix):
Install the etags and ctags man pages too.
* Makefile.in (distclean): Don't delete backup files; that's the
job of extraclean.
(extraclean): Like distclean, but deletes backup and autosave files.
Make path specification conform to GNU coding standards.
* configure (long_usage): Remove all traces of old arguments from
usage messages, and document the options we do accept in more
detail: -with-x... and --srcdir.
(options, boolean_opts): Deleted; we don't have enough options to
make this worthwhile.
(prefix, bindir, lisppath, datadir, libdir, lockdir): Deleted,
along with the code which supported them; these should be set as
arguments to the top-level make.
(config_h_opts): Since this no longer doubles as a list of option
names, make them upper case; this simplifies the code which uses
them to build the sed command to edit src/config.h. Change the
code which sets them.
(cc, g, O): Don't allow the user to set these using options; they
should be specified using `CC=' and `CFLAGS=' arguments to the
top-level make. Just choose reasonable default values for them,
and edit them into Makefile.in's default CC and CONFIG_CFLAGS
values.
(gnu_malloc, rel_alloc): Don't allow the user to set these using
options; use them whenever the configuration files say they're
possible.
Simplify the argument processing loop. Don't accept abbreviations
for option names; these might conflict with other configuration
options in the future.
Add some support for the `--srcdir' option. Check for the sources
in . and .. if `--srcdir' is omitted. If the directories we will
compile in don't exist yet, create them under the current directory.
Note that the rest of the build process doesn't really support
this.
Edit only the top Makefile. That should edit the others. Edit
into the makefile: `version', from lisp/version.el, `configname'
and `srcdir' from the configuration arguments, `CC' and
`CONFIG_CFLAGS' as guessed from the presence or absence of GCC in
the user's path, and LOADLIBES as gleaned from the system
description files.
Simplify the report generated; it doesn't need to include any
description of paths now.
Make `config.status' exec configure instead of just calling it, so
there's no harm in overwriting `config.status'.
* Makefile.in (version, configname): New variables, used to choose
the default values for datadir and libdir.
Path variables rearranged into two clearer groups:
- In the first group are the variables specified by the GNU coding
standards (prefix, bindir, datadir, statedir, libdir, mandir,
manext, infodir, and srcdir).
- In the second are the variables actually used for Emacs's paths
(lispdir, locallisppath, lisppath, buildlisppath, etcdir, lockdir,
archlibdir), which depend on the first category.
datadir and libdir default to directories under
${prefix}/lib/emacs instead of ${prefix}/emacs, by popular
demand.
etcdir and lispdir default to subdirectories of datadir.
archlibdir defaults to libdir.
The new installation tree is a bit deeper than it used to be, so
use the new make-path program in lib-src to build them all.
Always build a new src/paths.h.tmp and then move-if-change it to
src/paths.h, to avoid unnecessary rebuilds while responding to the
right changes.
Remove all mention of arch-lib. Run utility commands from
lib-src, and let the executables be copied into archlibdir when
Emacs is installed.
Add targets for src/Makefile, lib-src/Makefile, and
oldXMenu/Makefile, editing the values of the path variables into
them.
Let lib-src do its own installation.
(datadir): Default to putting data files under
${prefix}/lib/emacs/${version}, not /usr/local/emacs.
(emacsdir): Variable deleted; it would only be confusing to use.
(lispdir, etcdir): Default to ${datadir}/lisp.
(mkdir): Use make-path for this.
(lockdir): Do this in mkdir.
(Makefile): New target.
