# SYNOPSIS
#
# AX_MPI([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
# AX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro tries to find out how to compile programs that use MPI
# (Message Passing Interface), a standard API for parallel process
# communication (see http://www-unix.mcs.anl.gov/mpi/)
# 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.
#
# On success, it sets the MPICC, MPICXX, MPIF77, or MPIFC output variable
# to the name of the MPI compiler, depending upon the current language.
# (This may just be $CC/$CXX/$F77/$FC, but is more often something like
# mpicc/mpiCC/mpif77/mpif90.) It also sets MPILIBS to any libraries that
# are needed for linking MPI (e.g. -lmpi or -lfmpi, if a special
# MPICC/MPICXX/MPIF77/MPIFC was not found).
# To link with BLAS, you should link with:
#
# If you want to compile everything with MPI, you should use something
# like this for C:
# $BLAS_LIBS $LIBS $FLIBS
#
# if test -z "$CC" && test -n "$MPICC"; then
# CC="$MPICC"
# fi
# AC_PROG_CC
# AX_MPI
# CC="$MPICC"
# LIBS="$MPILIBS $LIBS"
# 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.
#
# and similar for C++ (change all instances of CC to CXX), Fortran 77
# (with F77 instead of CC) or Fortran (with FC instead of CC).
# 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.
#
# NOTE: The above assumes that you will use $CC (or whatever) for linking
# as well as for compiling. (This is the default for automake and most
# Makefiles.)
#
# The user can force a particular library/compiler by setting the
# MPICC/MPICXX/MPIF77/MPIFC and/or MPILIBS environment variables.
#
# ACTION-IF-FOUND is a list of shell commands to run if an MPI library is
# found, and ACTION-IF-NOT-FOUND is a list of commands to run if it is not
# found. If ACTION-IF-FOUND is not specified, the default action will
# define HAVE_MPI.
# 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_ELISP_CONFIG_FILE(FILENAME)
# AX_ELISP_CHECK(SYMBOL,DESCRIPTION,BODY,SUCCESS-EXPR)
# AX_ELISP_CHECK_FEATURE(SYMBOL)
# AX_ELISP_CHECK_FBOUNDP(SYMBOL,[FEATURE [...]])
# AX_ELISP_CHECK_BOUNDP(SYMBOL,[FEATURE [...]])
#
# DESCRIPTION
#
# This is a simple library to check the Emacs reality by way of Emacs Lisp
# forms evaluated under $EMACS --batch -Q. This means you MUST have the
# shell variable EMACS set to a valid Emacs executable prior to the first
# call to any of the AX_ELISP_CHECK et al macros. Those work by saving
# their results to the file defined by calling AX_ELISP_CONFIG_FILE so you
# MUST call that prior, too. For example:
#
# dnl Arrange to save config answers in $top_builddir/lisp/config.el.
# AX_ELISP_CONFIG_FILE([lisp/config.el])
#
# dnl Set shell variable EMACS and AC_SUBST it, too.
# dnl (NB: This is a separate Autoconf Archive macro.)
# AX_PROG_EMACS
#
# In the following detailed descriptions, SYMBOL stands for an Emacs Lisp
# symbol, which may contain hyphens, e.g., 'define-error' or 'org-src'.
# Likewise, FEATURE is an Emacs Lisp symbol (naming a feature). BODY and
# SUCCESS-EXPR are Emacs Lisp forms, zero or more for BODY and exactly one
# for SUCCESS-EXPR. In these forms you must take care to avoid apostrophe
# (U+27). Instead of 'foo, write (quote foo).
#
# * AX_ELISP_CONFIG_FILE(FILENAME)
#
# This arranges for future AX_ELISP_CHECK (et al) calls to save their
# results in FILENAME. May be called multiple times. FILENAME should be
# relative to the top build dir.
#
# * AX_ELISP_CHECK(SYMBOL,DESCRIPTION,BODY,SUCCESS-EXPR)
#
# This is the general macro that the other AX_ELISP_CHECK* macros use. It
# constructs a short Emacs Lisp file comprising BODY and evaluates it via
# $EMACS --batch -Q. The exit value of this script depends on the result
# of evaluating SUCCESS-EXPR: non-nil is success and nil is failure. On
# success, append SYMBOL on a line of its own to the config file. This
# macro uses AC_CACHE_CHECK and passes DESCRIPTION to it.
#
# * AX_ELISP_CHECK_FEATURE(FEATURE)
#
# This checks if (require (quote FEATURE)) is successful. If so, add
# featurep-FEATURE to the config file (NB the "featurep-" prefix).
#
# * AX_ELISP_CHECK_FBOUNDP(SYMBOL,[FEATURE [...]])
#
# This checks if (fboundp (quote SYMBOL)) is successful. If so, append
# SYMBOL to the config file. Optional 2nd arg is a space-separated list of
# features to require prior to the fboundp check.
#
# * AX_ELISP_CHECK_BOUNDP(SYMBOL,[FEATURE [...]])
#
# This checks if (boundp (quote SYMBOL)) is successful. If so, append
# SYMBOL to the config file. Optional 2nd arg is a space-separated list of
# features to require prior to the boundp check.

#
# 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.

# SYNOPSIS
#
# AX_PROG_CXX_MPI([MPI-WANTED-TEST[, ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
# This macro tries to find out how to compile C++ 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_CXX and will replace the
# standard variable CXX 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 C 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 C 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])

# SYNOPSIS
#
# AX_PROG_EMACS
#
# DESCRIPTION
#
# This macro allows the end user to specify a particular Emacs executable
# via a configure script command-line arg. For example:
#
# ./configure EMACS=$HOME/build/GNU/emacs/src/emacs
#
# It also arranges to mention env var EMACS in the './configure --help'
# output. See info node "(autoconf) Generic Programs" for details.
#
# More precisely...
#
# If env var EMACS is set, try to use its value directly, but avoid
# getting fooled by value 't' (set by older Emacsen for subprocesses). If
# no joy from the environment, search for "emacs" via AC_CHECK_PROG. If
# still no joy, display "Emacs not found; required!" and make configure
# exit failurefully. Otherwise, set shell var EMACS and AC_SUBST it, too.
