  25 ### Since Emacs has configuration requirements that autoconf can't
  26 ### meet, this file is an unholy marriage of custom-baked
  27 ### configuration code and autoconf macros.  New versions of autoconf
  28 ### could very well break this arrangement.
  29 ###
  30 ### We omit the invocation of autoconf's initialization function,
  31 ### because it produces Bourne shell code to parse arguments, but we
  32 ### need to parse our own arguments.
  33 ###
  34 ### We use the m4 quoting characters [ ] (as established by the
  35 ### autoconf system) to include large sections of raw sewage - Oops, I
  36 ### mean, shell code - in the final configuration script.
  37 ###
  38 ### Usage: configure config_name
  39 ###
  40 ### If configure succeeds, it leaves its status in config.status.
  41 ### If configure fails after disturbing the status quo,
  42 ###     config.status is removed.
  43
  44
  45 ### Remove any more than one leading "." element from the path name.
  46 ### If we don't remove them, then another "./" will be prepended to
  47 ### the file name each time we use config.status, and the program name
  48 ### will get larger and larger.  This wouldn't be a problem, except
  49 ### that since progname gets recorded in all the Makefiles this script
  50 ### produces, move-if-change thinks they're different when they're
  51 ### not.
  52 ###
  53 ### It would be nice if we could put the ./ in a \( \) group and then
  54 ### apply the * operator to that, so we remove as many leading ./././'s
  55 ### as are present, but some seds (like Ultrix's sed) don't allow you to
  56 ### apply * to a \( \) group.  Bleah.

  60 #### Usage messages.
  61
  62 short_usage="Type \`${progname} --usage' for more information about options."
  63
  64 long_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
  65
  66 Set compilation and installation parameters for GNU Emacs, and report.
  67 CONFIGURATION specifies the machine and operating system to build for.
  68 For example:
  69         ${progname} sparc-sun-sunos4.1
  70 configures Emacs to build on a Sun Sparc machine running SunOS 4.1, and
  71         ${progname} decstation
  72 configures Emacs to run on a DECstation running Ultrix.  See \`etc/MACHINES'.
  73
  74 The --with-x, --with-x11 and --with-x10 options specify what window
  75         system to use; if all are omitted, use X11 if present.  If you
  76         don't want X, specify \`--with-x=no'.
  77
  78 The --x-includes=DIR option tells the build process where to search
  79         for the X Windows header files.  DIR should have a
  80         subdirectory called \`X11' which contains \`X.h', \`Xlib.h', and
  81         the rest of the header files; DIR should not contain \`X11'
  82         itself.  If this option is omitted, the build process assumes
  83         they exist in a directory the compiler checks by default.
  84
  85 The --x-libraries=DIR option tells the build process where to look for
  86         the X windows libraries.  If this option is omitted, the build
  87         process assumes they are in a directory the compiler checks by
  88         default.
  89
  90 The --with-gcc option says that the build process should use GCC to
  91         compile Emacs.  If you have GCC but don't want to use it,
  92         specify \`--with-gcc=no'.  \`configure' tries to guess whether
  93         or not you have GCC by searching your executable path, but if
  94         it guesses incorrectly, you may need to use this.
  95
  96 The --run-in-place option sets up default values for the path
  97         variables in \`./Makefile' so that Emacs will expect to find
  98         its data files (lisp libraries, runnable programs, and the
  99         like) in the same locations they occupy while Emacs builds.
 100         This means that you don't have to install Emacs in order to
 101         run it; it uses its data files as they were unpacked.
 102
 103 The --srcdir=DIR option specifies that the configuration and build
 104         processes should look for the Emacs source code in DIR, when
 105         DIR is not the current directory.  This option doesn't work yet.
 106
 107 If successful, ${progname} leaves its status in config.status.  If
 108 unsuccessful after disturbing the status quo, it removes config.status."

 118 ### configuration or the run-in-place configuration.
