Set compilation and installation parameters for GNU Emacs, and report.
CONFIGURATION specifies the machine and operating system to build for.
For example:
${progname} sparc-sun-sunos4.1
configures Emacs to build on a Sun Sparc machine running SunOS 4.1, and
${progname} decstation
configures Emacs to run on a DECstation running Ultrix. See \`etc/MACHINES'.
The --with-x, --with-x11 and --with-x10 options specify what window
system to use; if all are omitted, use X11 if present. If you
don't want X, specify \`--with-x=no'.
The --x-includes=DIR option tells the build process where to search
for the X Windows header files. DIR should have a
subdirectory called \`X11' which contains \`X.h', \`Xlib.h', and
the rest of the header files; DIR should not contain \`X11'
itself. If this option is omitted, the build process assumes
they exist in a directory the compiler checks by default.
The --x-libraries=DIR option tells the build process where to look for
the X windows libraries. If this option is omitted, the build
process assumes they are in a directory the compiler checks by
The --with-gcc option says that the build process should use GCC to
compile Emacs. If you have GCC but don't want to use it,
specify \`--with-gcc=no'. \`configure' tries to guess whether
or not you have GCC by searching your executable path, but if
it guesses incorrectly, you may need to use this.
The --run-in-place option sets up default values for the path
variables in \`./Makefile' so that Emacs will expect to find
its data files (lisp libraries, runnable programs, and the
like) in the same locations they occupy while Emacs builds.
This means that you don't have to install Emacs in order to
run it; it uses its data files as they were unpacked.
The --srcdir=DIR option specifies that the configuration and build
processes should look for the Emacs source code in DIR, when
DIR is not the current directory.
--with-x Support the X Window System.
--with-x=no Don't support the X Window System.
--x-includes=DIR Search for X Window System header files in DIR.
--x-libraries=DIR Search for X Window System libraries in DIR.
--with-gcc Use GCC to compile Emacs.
--with-gcc=no Don't use GCC to compile Emacs.
--run-in-place Use libraries and data files directly out of the
source tree.
--srcdir=DIR Look for source in DIR.
--prefix=DIR Install files below dir.
If successful, ${progname} leaves its status in config.status. If
unsuccessful after disturbing the status quo, it removes config.status."
