\`configure' configures LinuxCNC 2.9.0~pre0 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]

  --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]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/linuxcnc]

                          Build documentation. FORMAT may be "Y" for both or
                          "pdf" or "html" if only one format is desired.
  --disable-check-runtime-deps
                          Skip checks for runtime requirements not needed
                          during the build process.

                          userspace.
  --with-kernel-headers=PATH
                          Location for kernel headers.

                          Force given directory for boost libraries. Note that
                          this will override library path detection, so use
                          this parameter only if default library detection
                          fails and you know exactly where your boost
                          libraries are located.

Some influential environment variables:
  CXX         C++ compiler command
  CXXFLAGS    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>
  CC          C compiler command
  CFLAGS      C compiler flags
  CPP         C preprocessor
  PYTHON_VERSION
              The installed Python version to use, for example '2.3'. This
              string will be appended to the Python interpreter canonical
              name.
  XMKMF       Path to xmkmf, Makefile generator for X Window System

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

# SYNOPSIS
#
#   AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
#
# DESCRIPTION
#
#   Check for baseline language coverage in the compiler for the C++11
#   standard; if necessary, add switches to CXXFLAGS to enable support.
#
#   The first argument, if specified, indicates whether you insist on an
#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
#   -std=c++11).  If neither is specified, you get whatever works, with
#   preference for an extended mode.
#
#   The second argument, if specified 'mandatory' or if left unspecified,
#   indicates that baseline C++11 support is required and that the macro
#   should error out if no mode with that support is found.  If specified
#   'optional', then configuration proceeds regardless, after defining
#   HAVE_CXX11 if and only if a supporting mode is found.

#
# DESCRIPTION
#
#   This macro does a complete Python development environment check.
#
#   It checks for all known versions. When it finds an executable, it looks
#   to find the header files and library.
#
#   It sets PYTHON_BIN to the name of the python executable,
#   PYTHON_INCLUDE_DIR to the directory holding the header files, and
#   PYTHON_LIB to the name of the Python library.
#
#   This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG),
#   PYTHON_INCLUDE_DIR and PYTHON_LIB.

# SYNOPSIS
#
#   AX_PYTHON_DEVEL([version])
#
# DESCRIPTION
#
#   Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
#   in your configure.ac.
#
#   This macro checks for Python and tries to get the include path to
#   'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) output
#   variables. It also exports $(PYTHON_EXTRA_LIBS) and
#   $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
#
#   You can search for some particular version of Python by passing a
#   parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
#   note that you *have* to pass also an operator along with the version to
#   match, and pay special attention to the single quotes surrounding the
#   version number. Don't use "PYTHON_VERSION" for this: that environment
#   variable is declared as precious and thus reserved for the end-user.
#
#   This macro should work for all versions of Python >= 2.1.0. As an end
#   user, you can disable the check for the python version by setting the
#   PYTHON_NOVERSIONCHECK environment variable to something else than the
#   empty string.
#
#   If you need to use this macro for an older Python version, please
#   contact the authors. We're always open for feedback.

# This is what autoupdate's m4 run will expand.  It fires the warning
# (with _au_warn_XXX), outputs it into the updated configure.ac (with
# m4_warn), and then outputs the replacement expansion.  We need extra
# quotation around the m4_warn and dnl so they will be written
# unexpanded into the updated configure.ac.


# This is an auxiliary macro that is also run when
# autoupdate runs m4.  It simply calls m4_warning, but
# we need a wrapper so that each warning is emitted only
# once.  We break the quoting in m4_warning's argument in
# order to expand this macro's arguments, not AU_DEFUN's.


# Finally, this is the expansion that is picked up by
# autoconf, causing NAME to expand to NEW-CODE, plus
# (if SILENT is not "silent") a m4_warning telling the
# maintainer to run autoupdate.  We don't issue MESSAGE
# from autoconf, because that's instructions for what
# to do *after* running autoupdate.

#
# SYNOPSIS
#
#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
#
# DESCRIPTION
#
#   Test for the Boost C++ libraries of a particular version (or newer)
#
#   If no path to the installed boost library is given the macro searches
#   under /usr, /usr/local, /opt and /opt/local and evaluates the
#   $BOOST_ROOT environment variable. Further documentation is available at
#   <http://randspringer.de/boost/index.html>.
#
#   This macro calls:
#
#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
#
#   And sets:
#
#     HAVE_BOOST

#
# SYNOPSIS
#
#   AX_BOOST_PYTHON
#
# DESCRIPTION
#
#   This macro checks to see if the Boost.Python library is installed. It
#   also attempts to guess the correct library name using several attempts.
#   It tries to build the library name using a user supplied name or suffix
#   and then just the raw library.
#
#   If the library is found, HAVE_BOOST_PYTHON is defined and
#   BOOST_PYTHON_LIB is set to the name of the library.
#
#   This macro calls AC_SUBST(BOOST_PYTHON_LIB).
#
#   In order to ensure that the Python headers and the Boost libraries are
#   specified on the include path, this macro requires AX_PYTHON_DEVEL and
#   AX_BOOST_BASE to be called.
