\`configure' configures libmesh 1.7.0-pre 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]
  --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]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/libmesh]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]

  YACC        The `Yet Another Compiler Compiler' implementation to use.
              Defaults to the first program found out of: `bison -y', `byacc',
              `yacc'.
  YFLAGS      The list of arguments that will be passed by default to $YACC.
              This script will default YFLAGS to the empty string to avoid a
              default value of `-d' given by some make applications.

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.

# We originally passed [enable] to AM_MAINTAINER_MODE, but this caused
# ordinary users to have to configure with --disable-maintainer-mode,
# which is easy to forget unless you are closely following the
# instructions, or are aware of the issue and have run the provided
# ./bootstrap script.
#
# We've now switched this to simply AM_MAINTAINER_MODE with no
# arguments, which is equivalent to AM_MAINTAINER_MODE([disable]).  In
# this configuration, developers who modify Makefile.am files (or
# other build system files) *must* configure with
# --enable-maintainer-mode in order for dependent files (Makefile.in,
# etc) to be properly rebuilt whenever changes to the build system are
# made.
#
# Note that this approach is not without its drawbacks and detractors:
# https://blogs.gnome.org/desrt/2011/09/08/am_maintainer_mode-is-not-cool
# https://www.gnu.org/software/automake/manual/html_node/maintainer_002dmode.html
# but the benefit is that casual and first-time users are not
# surprised by the default behavior of simply running ./configure.
#
# Note that we also do things a bit differently than most other
# projects regarding the number of auto-generated build files
# (Makefile.in) that are checked in, and it seems like the new
# approach makes more sense for the way our project works --
# rebuilding the build files are not part of a normal build for most
# users.

# Determine support for the C99 "restrict" keyword in the C++
# compiler.  This should place a pound-define statement in the
# config file along the lines of:
#
# #define _libmesh_restrict __restrict
#
# The restrict keyword allows the compiler to make
# certain optimizations which require non-overlapping pointer
# addresses, i.e. in a call to:
#
# foo(int* restrict a, int* restrict b)
#
# the compiler may assume that the memory addresses pointed to
# by a and b do not overlap, and therefore certain low-level
# optimizations can be made.  From the Autoconf documentation:
#
# If the C compiler recognizes a variant spelling for the restrict
# keyword (__restrict, __restrict__, or _Restrict), then define restrict
# to that; this is more likely to do the right thing with compilers that
# support language variants where plain restrict is not a
# keyword. Otherwise, if the C compiler recognizes the restrict keyword,
# don't do anything. Otherwise, define restrict to be empty. Thus,
# programs may simply use restrict as if every C compiler supported it;
# for those that do not, the makefile or configuration header defines it
# away.
#
# Although support in C++ for the restrict keyword is not required,
# several C++ compilers do accept the keyword. This macro works for
# them, too.
#
# This macro caches 'no' in the ac_cv_c_restrict variable if restrict is
# not supported, and a supported spelling otherwise.

# -pthread: Linux/gcc (kernel threads), BSD/gcc (userland threads)
# -pthreads: Solaris/gcc
# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
#      doesn't hurt to check since this sometimes defines pthreads too;
