21 # Shell script to edit files and make symlinks in preparation for
24 # Usage: configure machine
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.
31 # Remove any leading "." elements from the path name. When this
32 # script is invoked from the config.status script, a new ./ gets added
33 # to the the front of the path, resulting in a "././" prefix. That
34 # prefix is then recorded in the resulting config.status file, so
35 # basically each time config.status is used, it prepends another "./"
36 # to the filename. This wouldn't be a problem, except that since
37 # progname gets recorded in all the Makefiles this script produces,
38 # move-if-changed thinks they're different when they're not.

53 -g, -O - Passed to the compiler. If omitted, use -O only.
54 -cc=COMPILER - Which compiler to use. Defaults to gcc if available.
55 -libdir=DIR - where to look for arch-dependent library files
56 -datadir=DIR - where to look for architecture-independent library files
57 -bindir=DIR - where to install the Emacs executable, and some friends
58 -lisppath=PATH - colon-separated list of Elisp directories
59 -lockdir=DIR - where Emacs should do its file-locking stuff
60 -window_system=none or [x11, if it is installed] - what window system to use
61 -have_x_menu=yes or [no] - include menu support under X11
62 -gnu_malloc=[yes] or no - use the GNU memory allocator
63 -rel_alloc=[yes] or no - use compacting allocator for buffers
64 -highpri=N - run at N points higher-than-normal priority
65 -lisp_float_type=[yes] or no - Support native floating point in Elisp
