MACHINENAME [-OPTION[=VALUE] ...]
Set compilation and installation parameters for GNU Emacs, and report.
MACHINENAME is the machine to build for. See
\`
etc/MACHINES'.
Options are:
-opsystem=SYSTEM - operating system to build for; see
\`
etc/MACHINES'.
-libroot=DIR - where to install Emacs's library files
These options have reasonable defaults (in []s), and may not be needed:
-g, -O - Passed to the compiler. If omitted, use -O only.
-cc=COMPILER - Which compiler to use. Defaults to gcc if available.
-libdir=DIR - where to look for arch-dependent library files
-datadir=DIR - where to look for architecture-independent library files
-installbin=DIR - where to install the Emacs executable, and some friends
-lisppath=PATH - colon-separated list of Elisp directories
-lockdir=DIR - where Emacs should do its file-locking stuff
-window_system=none or [x11, if it is installed] - what window system to use
-have_x_menu=yes or [no] - include menu support under X11
-gnu_malloc=[yes] or no - use the GNU memory allocator
-rel_alloc=[yes] or no - use compacting allocator for buffers
-highpri=N - run at N points higher-than-normal priority
-lisp_float_type=[yes] or no - Support floating point in Elisp
If successful,
${
progname
}
leaves its status in config.status. If
unsuccessful after disturbing the status quo, config.status is removed."
