\`configure' configures Macaulay2 1.25.11 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]

                          specified, then the system's default version will be
                          detected. Use --without-python to turn off Python
                          support.
  --with-boost[=ARG]      use Boost library from a standard location
                          (ARG=yes), from the specified location (ARG=<path>),

  --with-boost-libdir=LIB_DIR
                          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.
  --with-boost-regex[=special-lib]
                          use the Regex library from boost - it is possible to
                          specify a certain library for the linker e.g.
                          --with-boost-regex=boost_regex-gcc-mt-d-1_33_1
  --with-fplll            enable linking with the fplll library
  --without-libffi        don't link with libffi, disabling the
                          ForeignFunctions package
  --with-emacsdir=...     set installation directory for installing Emacs Lisp
                          files; must begin with ${prefix} or ${exec_prefix}
  --with-staging-area=... directory for pre-installation of
                          architecture-independent files (usr-dist)

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>
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  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.
  FC          Fortran compiler command
  FCFLAGS     Fortran compiler flags
  F77         Fortran 77 compiler command
  FFLAGS      Fortran 77 compiler flags
  GFTABLESDIR path to gftables directory if factory is already installed

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_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
#
# DESCRIPTION
#
#   This macro compares two version strings. Due to the various number of
#   minor-version numbers that can exist, and the fact that string
#   comparisons are not compatible with numeric comparisons, this is not
#   necessarily trivial to do in a autoconf script. This macro makes doing
#   these comparisons easy.
#
#   The six basic comparisons are available, as well as checking equality
#   limited to a certain number of minor-version levels.
#
#   The operator OP determines what type of comparison to do, and can be one
#   of:
#
#    eq  - equal (test A == B)
#    ne  - not equal (test A != B)
#    le  - less than or equal (test A <= B)
#    ge  - greater than or equal (test A >= B)
#    lt  - less than (test A < B)
#    gt  - greater than (test A > B)
#
#   Additionally, the eq and ne operator can have a number after it to limit
#   the test to that number of minor versions.
#
#    eq0 - equal up to the length of the shorter version
#    ne0 - not equal up to the length of the shorter version
#    eqN - equal up to N sub-version levels
#    neN - not equal up to N sub-version levels
#
#   When the condition is true, shell commands ACTION-IF-TRUE are run,
#   otherwise shell commands ACTION-IF-FALSE are run. The environment
#   variable 'ax_compare_version' is always set to either 'true' or 'false'
#   as well.
#
#   Examples:
#
#     AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
#     AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
#
#   would both be true.
#
#     AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
#     AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
#
#   would both be false.
#
#     AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
#
#   would be true because it is only comparing two minor versions.
#
#     AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
#
#   would be true because it is only comparing the lesser number of minor
#   versions of the two values.
#
#   Note: The characters that separate the version numbers do not matter. An
#   empty string is the same as version 0. OP is evaluated by autoconf, not
#   configure, so must be a string, not a variable.
#
#   The author would like to acknowledge Guido Draheim whose advice about
#   the m4_case and m4_ifvaln functions make this macro only include the
#   portions necessary to perform the specific comparison specified by the
#   OP argument in the final configure script.

# AC_OPENMP
# ---------
# Check which options need to be passed to the C compiler to support OpenMP.
# Set the OPENMP_CFLAGS / OPENMP_CXXFLAGS / OPENMP_FFLAGS variable to these
# options.
# The options are necessary at compile time (so the #pragmas are understood)
# and at link time (so the appropriate library is linked with).
# This macro takes care to not produce redundant options if $CC $CFLAGS already
# supports OpenMP. It also is careful to not pass options to compilers that
# misinterpret them; for example, most compilers accept "-openmp" and create
# an output file called 'penmp' rather than activating OpenMP support.


# Here we introduce a macro that is derived from AC_SEARCH_LIBS, but modified
# so we can specify libraries as absolute paths, such as /usr/local/lib/libfoo.a or -lfoo.
# The point of this is so we can link with the static version of the library instead
# of the dynamic version.  We need something like this, because the BSD "ld" command
# provided by Mac OS does not offer a command line option to achieve it.

# =============================================================================

# -- Macro: SEARCH_LIBRARIES (FUNCTION, SEARCH-LIBS, [ACTION-IF-FOUND],
#          [ACTION-IF-NOT-FOUND], [OTHER-LIBRARIES])
#     Search for a library defining FUNCTION if it's not already
#     available.  This equates to calling
#     `AC_LINK_IFELSE([AC_LANG_CALL([], [FUNCTION])])' first with no
#     libraries, then for each library listed in SEARCH-LIBS.

#     Prepend `LIBRARY' to `LIBS' for the first library found to
#     contain FUNCTION, and run ACTION-IF-FOUND.  If the function is not
#     found, run ACTION-IF-NOT-FOUND.

#     If linking with LIBRARY results in unresolved symbols that would
#     be resolved by linking with additional libraries, give those
#     libraries as the OTHER-LIBRARIES argument, separated by spaces:
#     e.g., `-lXt -lX11'.  Otherwise, this macro fails to detect that
#     FUNCTION is present, because linking the test program always fails
#     with unresolved symbols.

#     The result of this test is cached in the `ac_cv_search_FUNCTION'
#     variable as `none required' if FUNCTION is already available, as
#     `no' if no library containing FUNCTION was found, otherwise as the
#     `LIBRARY' option that needs to be prepended to `LIBS'.

#   interface (see http://www.netlib.org/blas/). On success, it sets the
#   BLAS_LIBS output variable to hold the requisite library linkages.
#
#   To link with BLAS, you should link with:
#
#     $BLAS_LIBS $LIBS $FLIBS
#
#   in that order. FLIBS is the output variable of the
#   AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is
#   sometimes necessary in order to link with F77 libraries. Users will also
#   need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same
#   reason.
#
#   Many libraries are searched for, from ATLAS to CXML to ESSL. The user
#   may also use --with-blas=<lib> in order to use some specific BLAS
#   library <lib>. In order to link successfully, however, be aware that you
#   will probably need to use the same Fortran compiler (which can be set
#   via the F77 env. var.) as was used to compile the BLAS library.
#
#   ACTION-IF-FOUND is a list of shell commands to run if a BLAS library is
#   found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is
#   not found. If ACTION-IF-FOUND is not specified, the default action will
#   define HAVE_BLAS.

# SYNOPSIS
#
#   AX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   This macro looks for a library that implements the LAPACK linear-algebra
#   interface (see http://www.netlib.org/lapack/). On success, it sets the
#   LAPACK_LIBS output variable to hold the requisite library linkages.
#
#   To link with LAPACK, you should link with:
#
#     $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS
#
#   in that order. BLAS_LIBS is the output variable of the AX_BLAS macro,
#   called automatically. FLIBS is the output variable of the
#   AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is
#   sometimes necessary in order to link with F77 libraries. Users will also
#   need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same
#   reason.
#
#   The user may also use --with-lapack=<lib> in order to use some specific
#   LAPACK library <lib>. In order to link successfully, however, be aware
#   that you will probably need to use the same Fortran compiler (which can
#   be set via the F77 env. var.) as was used to compile the LAPACK and BLAS
#   libraries.
#
#   ACTION-IF-FOUND is a list of shell commands to run if a LAPACK library
#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
#   is not found. If ACTION-IF-FOUND is not specified, the default action
#   will define HAVE_LAPACK.

# The list BUILTLIBS is the list of link options for the libraries we have decided to build,
#    of the form "-lFOO", which will be used to link Macaulay2 later on.  These libraries are not
#    available at the time this configure script is run, which is why we can't add "-lFOO" to LIBS.
#    (Programs linked by this configure script are linked with the options in LIBS.  This allows libraries
#    dependent on previously detected libraries to be detected by tests that involve linking.

LIBLIST=" gc gdbm gmp mpfr mpfi normaliz readline ntl flint factory lapack mpsolve frobby glpk cddlib fplll givaro fflas_ffpack linbox gtest tbb memtailor mathic mathicgb eigen "

# The list LIBLIST is the list of libraries that might be used and linked into M2.

PROGLIST="4ti2 gfan csdp nauty cddplus lrslib topcom cohomcalg msolve"

# The list PROGLIST is the list of programs and libraries for them that are distributed with M2.
#     Initially, we offer no option for not compiling some of them.

# These three lists reflect dependencies, with prerequisites listed first, including the following dependencies:
#    mathicgb needs mathic and memtailor
#    mathic needs memtailor
#    factory needs flint, ntl and gmp; it includes and installs gftables, so doesn't need it separately
#    libfac has been replaced by code in factory
#    lapack includes blas, makes both libblas and liblapack
#    mpfr needs gmp
#    	  mpfr puts pointers to gmp numbers in thread local variables, unless
# 	  specially configured, so we shouldn't tell gmp to use libgc (we used to do that)
#    ntl needs gmp
#    4ti2 needs glpk
#    glpk needs gmp
#    topcom depends on cddlib
#    gfan needs cddlib
#    cddlib uses gmp
#    polymake cannot be included in Macaulay2 because its compile/build/install procedure is flawed:
#	it uses a dynamic readline library that can only be provided by fink and probably will not be copied into the install location
#       it offers no way to provide a directory tree containing a readline library we've compiled
#	it writes a file into the user's home directory called ".polymake"
#	it asks questions
#    normaliz needs libgmp, libgmpxx, boost
#    Greg Smith requested cddplus and lrslib for future use
#    nauty is used by the package Nauty
#    normaliz is used by the package Normaliz
#    gfan is used by the packages gfanInterface and StatePolytope
#    4ti2 is used by the package FourTiTwo
#    linbox is provided as an option for experimentation
#    linbox needs fflas_ffpack and givaro
