  21 # Shell script to edit files and make symlinks in preparation for
  22 # compiling Emacs.
  23 #
  24 # Usage: configure config_name
  25 #
  26 # If configure succeeds, it leaves its status in config.status.
  27 # If configure fails after disturbing the status quo,
  28 #       config.status is removed.
  29 #
  30
  31 # Remove any leading "." elements from the path name.  If we don't
  32 # remove them, then another "./" will be prepended to the file name
  33 # each time we use config.status, and the program name will get larger
  34 # and larger.  This wouldn't be a problem, except that since progname
  35 # gets recorded in all the Makefiles this script produces,
  36 # move-if-changed thinks they're different when they're not.
  37 #
  38 # It would be nice if we could put the ./ in a \( \) group and then
  39 # apply the * operator to that, so we remove as many leading ./././'s
  40 # as are present, but some seds (like Ultrix's sed) don't allow you to
  41 # apply * to a \( \) group.  Bleah.

  47
  48 Set compilation and installation parameters for GNU Emacs, and report.
  49 CONFIGURATION specifies the machine and operating system to build for.
  50 For example:
  51         ${progname} sparc-sun-sunos4.1
  52 configures Emacs to build on a Sun Sparc machine running SunOS 4.1, and
  53         ${progname} decstation
  54 configures Emacs to run on a DECstation running Ultrix.  See \`etc/MACHINES'.
  55 Options are:
  56   --with-x, --with-x11 or --with-x10 - what window system to use;
  57          default is to use X11 if present.  If you don't want X, specify
  58          \`--with-x=no'.
  59   -g, -O - Passed to the compiler.  Default is -g, plus -O if using gcc.
  60   --prefix=DIR - where to install Emacs's library files
  61   --libdir=DIR - where to look for arch-dependent library files
  62   --datadir=DIR - where to look for architecture-independent library files
  63   --bindir=DIR - where to install the Emacs executable, and some friends
  64   --lisppath=PATH - colon-separated list of Emacs Lisp directories
  65   --lockdir=DIR - where Emacs should do its file-locking stuff
  66 If successful, ${progname} leaves its status in config.status.  If
  67 unsuccessful after disturbing the status quo, config.status is removed."
  68 # These are omitted since users should not mess with them.
  69 #  --gnu-malloc=[yes] or no - use the GNU memory allocator
  70 #  --rel-alloc=[yes] or no - use compacting allocator for buffers
  71 #  --lisp-float-type=[yes] or no - Support floating point in Emacs Lisp.
  72 # --window-system is omitted because --with... follow the conventions.

 225 ### based on the machine portion of the configuration name, and an s-
 226 ### file based on the operating system portion.  However, it turns out
 227 ### that each m/*.h file is pretty manufacturer-specific - for
 228 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
 229 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
 230 ### machines.  So we basically have to have a special case for each
 231 ### configuration name.

 233 ### As far as handling version numbers on operating systems is
 234 ### concerned, make sure things will fail in a fixable way.  If
 235 ### /etc/MACHINES doesn't say anything about version numbers, be
 236 ### prepared to handle anything reasonably.  If version numbers
 237 ### matter, be sure /etc/MACHINES says something about it.

 991 The following values have been set in ./Makefile and ./build-install:
 992   \`make install' or \`build-install' will place executables in
 993         ${bindir}.
 994   Emacs's lisp search path will be
 995         \`${lisppath}'.
 996   Emacs will look for its architecture-independent data in
 997         ${datadir}.
 998   Emacs will look for its utility programs and other architecture-
 999   dependent data in
1000         ${libdir}.
1001   Emacs will keep track of file-locking in
1002         ${lockdir}.

1008   Should Emacs use the relocating allocator for buffers?  ${rel_alloc}
1009   Should Emacs support a floating point data type?        ${lisp_float_type}
1010   What window system should Emacs use?                    ${window_system}
1011   What compiler should emacs be built with?               ${cc}
