13 ### Don't edit this script!
14 ### This script was automatically generated by the `autoconf' program
15 ### from the file `./configure.in'.
16 ### To rebuild it, execute the command
17 ### autoconf

36 ### Since Emacs has configuration requirements that autoconf can't
37 ### meet, this file is an unholy marriage of custom-baked
38 ### configuration code and autoconf macros.
39 ###
40 ### We use the m4 quoting characters [ ] (as established by the
41 ### autoconf system) to include large sections of raw sewage - Oops, I
42 ### mean, shell code - in the final configuration script.
43 ###
44 ### Usage: configure config_name
45 ###
46 ### If configure succeeds, it leaves its status in config.status.
47 ### If configure fails after disturbing the status quo,
48 ### config.status is removed.
50 ### Remove any more than one leading "." element from the path name.
51 ### If we don't remove them, then another "./" will be prepended to
52 ### the file name each time we use config.status, and the program name
53 ### will get larger and larger. This wouldn't be a problem, except
54 ### that since progname gets recorded in all the Makefiles this script
55 ### produces, move-if-change thinks they're different when they're
56 ### not.
57 ###
58 ### It would be nice if we could put the ./ in a \( \) group and then
59 ### apply the * operator to that, so we remove as many leading ./././'s
60 ### as are present, but some seds (like Ultrix's sed) don't allow you to
61 ### apply * to a \( \) group. Bleah.

91 #### Usage messages.
93 short_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
95 Set compilation and installation parameters for GNU Emacs, and report.
96 CONFIGURATION specifies the machine and operating system to build for.
97 --with-x Support the X Window System.
98 --with-x=no Don't support X.
99 --x-includes=DIR Search for X header files in DIR.
100 --x-libraries=DIR Search for X libraries in DIR.
101 --with-gcc Use GCC to compile Emacs.
102 --with-gcc=no Don't use GCC to compile Emacs.
103 --run-in-place Use libraries and data files directly out of the
104 source tree.
105 --single-tree=DIR Has the effect of creating a directory tree at DIR
106 which looks like:
107 .../DIR/bin/CONFIGNAME (emacs, etags, etc.)
108 .../DIR/bin/CONFIGNAME/etc (movemail, etc.)
109 .../DIR/common/lisp (emacs' lisp files)
110 .../DIR/common/site-lisp (local lisp files)
111 .../DIR/common/lib (DOC, TUTORIAL, etc.)
112 .../DIR/common/lock (lockfiles)
113 --srcdir=DIR Look for the Emacs source files in DIR.
114 --prefix=DIR Install files below DIR. Defaults to \`${prefix}'.
116 You may also specify any of the \`path' variables found in Makefile.in,
117 including --bindir, --libdir, --etcdir, --infodir, and so on. This allows
118 you to override a single default location when configuring.
120 If successful, ${progname} leaves its status in config.status. If
121 unsuccessful after disturbing the status quo, it removes config.status."
124 #### Option processing.
126 ### Record all the arguments, so we can save them in config.status.
127 arguments="$@"
129 ### Shell Magic: Quote the quoted arguments in ARGUMENTS. At a later date,
130 ### in order to get the arguments back in $@, we have to do an
131 ### `eval set x "$quoted_arguments"; shift'.
132 quoted_arguments=
133 for i in "$@"; do
134 quoted_arguments="$quoted_arguments '$i'"
135 done
137 ### Don't use shift -- that destroys the argument list, which autoconf needs
138 ### to produce config.status. It turns out that "set - ${arguments}" doesn't
139 ### work portably.
140 ### However, it also turns out that many shells cannot expand ${10} at all.
141 ### So using an index variable doesn't work either. It is possible to use
142 ### some shell magic to make 'set x "$arguments"; shift' work portably.
