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

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