'configure' configures GNU coreutils 9.7 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print 'checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for '--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or '..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, 'make install' will install all the files in
'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc. You can specify
an installation prefix other than '$ac_default_prefix' using '--prefix',
for instance '--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]

Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-silent-rules less verbose build output (undo: "make V=1")
--disable-silent-rules verbose build output (undo: "make V=0")
--enable-dependency-tracking
do not reject slow dependency extractors
--disable-dependency-tracking
speeds up one-time build
--disable-largefile omit support for large files
--enable-threads={isoc|posix|isoc+posix|windows}
specify multithreading API
--disable-threads build without multithread safety
--enable-cross-guesses={conservative|risky}
specify policy for cross-compilation guesses
--disable-acl do not support ACLs
--disable-assert turn off assertions
--disable-rpath do not hardcode runtime library paths
--disable-xattr do not support extended attributes
--enable-systemd use systemd APIs
--disable-libsmack disable libsmack support
--disable-libcap disable libcap support
--enable-single-binary=shebangs|symlinks
Compile all the tools in a single binary, reducing
the overall size. When compiled this way, shebangs
(default when enabled) or symlinks are installed for
each tool that points to the single binary.
--enable-single-binary-exceptions=PROG_LIST
When used with --enable-single-binary, exclude the
PROG_LIST from it, so these programs are compiled as
separated files (comma-separated, default none))
--disable-bold-man-page-references
When generating man pages, do not apply bold style
around any references like name(1) etc.
--enable-gcc-warnings[=TYPE]
control generation of GCC warnings. The TYPE 'no'
disables warnings (default for non-developer
builds); 'yes' generates cheap warnings if available
(default for developer builds); 'expensive' in
addition generates expensive-to-compute warnings if
available.
--enable-install-program=PROG_LIST
install the programs in PROG_LIST (comma-separated,
default: none)
--enable-no-install-program=PROG_LIST
do NOT install the programs in PROG_LIST
(comma-separated, default: arch,coreutils,hostname)
--disable-nls do not use Native Language Support
--disable-year2038 don't support timestamps after 2038
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--without-libsmack do not use libsmack, even on systems that have it
--with-linux-crypto use Linux kernel cryptographic API (if available)
for the hash functions MD5, SHA-1, SHA-224, SHA-256,
SHA-384, SHA-512 on files
--with-openssl[=ARG] use libcrypto hash routines for the hash functions
MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512.
Valid ARGs are:
'yes',
'no',
'auto' => use if any version available,
'auto-gpl-compat' => use if GPL compatible version
available,
'optional' => use if available
and warn if not available;
Default is 'auto-gpl-compat'.
Note also --with-linux-crypto, which will enable the
use of Linux kernel crypto routines (if available),
which has precedence for files.
--without-selinux do not use SELinux, even on systems with SELinux
--with-gnulib-prefix=DIR search for gnulib's runtime data in DIR/share
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
--without-libgmp do not use the GNU Multiple Precision (GMP) library;
this is the default on systems lacking libgmp.
--with-libgmp-prefix[=DIR] search for libgmp in DIR/include and DIR/lib
--without-libgmp-prefix don't search for libgmp in includedir and libdir
--without-included-regex
don't compile regex; this is the default on systems
with recent-enough versions of the GNU C Library
(use with caution on other systems).
--with-packager String identifying the packager of this software
--with-packager-version Packager-specific version information
--with-packager-bug-reports
Packager info for bug reports (URL/e-mail/...)
--with-tty-group[=NAME]
group used by system for TTYs, "tty" when not
specified (default: do not rely on any group used
for TTYs)
--with-libintl-prefix[=DIR] search for libintl in DIR/include and DIR/lib
--without-libintl-prefix don't search for libintl in includedir and libdir
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
YACC The "Yet Another C Compiler" implementation to use. Defaults to
'bison -o y.tab.c'. Values other than 'bison -o y.tab.c' will
most likely break on most systems.
YFLAGS YFLAGS contains the list arguments that will be passed by
default to Bison. This script will default YFLAGS to the empty
string to avoid a default value of '-d' given by some make
applications.
DEFAULT_POSIX2_VERSION
POSIX version to default to; see 'config.hin'.
Use these variables to override the choices made by 'configure' or to help
it to find libraries and programs with nonstandard names/locations.

Oops!
Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message. This
can help us improve future automake versions.

Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: <https://www.gnu.org/software/coreutils/>.
If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.

# year2038 module does): It leaves the upper 32 bits of the tv_sec field

# Solaris 2.5.1 needs -lposix4 to get the clock_gettime function.
# Solaris 7 prefers the library name -lrt to the obsolescent name -lposix4.
# Save and restore LIBS so e.g., -lrt, isn't added to it. Otherwise, *all*
