# SYNOPSIS
#
#   AX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   This macro looks for a library that implements the BLAS linear-algebra
#   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.

#   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.

# SYNOPSIS
#
#   AX_OPENMP([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   This macro tries to find out how to compile programs that use OpenMP a
#   standard API and set of compiler directives for parallel programming
#   (see http://www-unix.mcs/)
#
#   On success, it sets the OPENMP_CFLAGS/OPENMP_CXXFLAGS/OPENMP_F77FLAGS
#   output variable to the flag (e.g. -omp) used both to compile *and* link
#   OpenMP programs in the current language.
#
#   NOTE: You are assumed to not only compile your program with these flags,
#   but also link it with them as well.
#
#   If you want to compile everything with OpenMP, you should set:
#
#     CFLAGS="$CFLAGS $OPENMP_CFLAGS"
#     #OR#  CXXFLAGS="$CXXFLAGS $OPENMP_CXXFLAGS"
#     #OR#  FFLAGS="$FFLAGS $OPENMP_FFLAGS"
#
#   (depending on the selected language).
#
#   The user can override the default choice by setting the corresponding
#   environment variable (e.g. OPENMP_CFLAGS).
#
#   ACTION-IF-FOUND is a list of shell commands to run if an OpenMP flag 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_OPENMP.

# SYNOPSIS
#
#   AX_PROG_FC_MPI([MPI-WANTED-TEST[, ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
#   This macro tries to find out how to compile Fortran77 programs that use
#   MPI (Message Passing Interface), a standard API for parallel process
#   communication (see http://www-unix.mcs.anl.gov/mpi/).  The macro has to
#   be used instead of the standard macro AC_PROG_FC and will replace the
#   standard variable FC with the found compiler.
#
#   MPI-WANTED-TEST is used to test whether MPI is actually wanted by the
#   user. If MPI-WANTED_TEST is omitted or if it succeeds, the macro will
#   try to find out how to use MPI, if it fails, the macro will call
#   AC_PROG_CC to find a standard C compiler instead.
#
#   When MPI is found, ACTION-IF-FOUND will be executed, if MPI is not found
#   (or MPI-WANTED-TEST fails) ACTION-IF-NOT-FOUND is executed. If
#   ACTION-IF-FOUND is not set, the macro will define HAVE_MPI.
#
#   The following example demonstrates usage of the macro:
#
#     # If --with-mpi=auto is used, try to find MPI, but use standard FC compiler if it is not found.
#     # If --with-mpi=yes is used, try to find MPI and fail if it isn't found.
#     # If --with-mpi=no is used, use a standard FC compiler instead.
#     AC_ARG_WITH(mpi, [AS_HELP_STRING([--with-mpi],
#         [compile with MPI (parallelization) support. If none is found,
#         MPI is not used. Default: auto])
#     ],,[with_mpi=auto])
#
#     AX_PROG_FC_MPI([test x"$with_mpi" != xno],[use_mpi=yes],[
#       use_mpi=no
#       if test x"$with_mpi" = xyes; then
#         AC_MSG_FAILURE([MPI compiler requested, but couldn't use MPI.])
#       else
#         AC_MSG_WARN([No MPI compiler found, won't use MPI.])

#
# This file is free software; the Free Software Foundation

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory.  The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run.  This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
#    fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
#    fails if $ac_aux_dir is absolute,
#    fails when called from a subdirectory in a VPATH build with
#          a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir.  In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
#   MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH.  The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

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

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: <http://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.

# AM_PROG_INSTALL_STRIP
# ---------------------
# One issue with vendor 'install' (even GNU) is that you can't
# specify the program used to strip binaries.  This is especially
# annoying in cross-compiling environments, where the build's strip
# is unlikely to handle the host's binaries.
# Fortunately install-sh will honor a STRIPPROG variable, so we
# always use install-sh in "make install-strip", and initialize
# STRIPPROG with the value of the STRIP variable (set by the user).

# Installed binaries are usually stripped using 'strip' when the user
# run "make install-strip".  However 'strip' might not be the right
# tool to use in cross-compilation environments, therefore Automake
# will honor the 'STRIP' environment variable to overrule this program.
