# SYNOPSIS
#
#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   This macro figures out how to build C programs using POSIX threads. It
#   sets the PTHREAD_LIBS output variable to the threads library and linker
#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
#   flags that are needed. (The user can also force certain compiler
#   flags/libs to be tested by setting these environment variables.)
#
#   Also sets PTHREAD_CC to any special C compiler that is needed for
#   multi-threaded programs (defaults to the value of CC otherwise). (This
#   is necessary on AIX to use the special cc_r compiler alias.)
#
#   NOTE: You are assumed to not only compile your program with these flags,
#   but also link it with them as well. e.g. you should link with
#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
#   If you are only building threads programs, you may wish to use these
#   variables in your default LIBS, CFLAGS, and CC:
#
#          LIBS="$PTHREAD_LIBS $LIBS"
#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
#          CC="$PTHREAD_CC"
#
#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
#   ACTION-IF-FOUND is a list of shell commands to run if a threads 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_PTHREAD.
#
#   Please let the authors know if this macro fails on any platform, or if
#   you have any other suggestions or comments. This macro was based on work
#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
#   grateful for the helpful feedback of numerous users.

# -pthreads: Solaris/gcc

# SYNOPSIS
#
#   DX_INIT_DOXYGEN(PROJECT-NAME, DOXYFILE-PATH, [OUTPUT-DIR])
#   DX_DOXYGEN_FEATURE(ON|OFF)
#   DX_DOT_FEATURE(ON|OFF)
#   DX_HTML_FEATURE(ON|OFF)
#   DX_CHM_FEATURE(ON|OFF)
#   DX_CHI_FEATURE(ON|OFF)
#   DX_MAN_FEATURE(ON|OFF)
#   DX_RTF_FEATURE(ON|OFF)
#   DX_XML_FEATURE(ON|OFF)
#   DX_PDF_FEATURE(ON|OFF)
#   DX_PS_FEATURE(ON|OFF)
#
# DESCRIPTION
#
#   The DX_*_FEATURE macros control the default setting for the given
#   Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
#   generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
#   help (for MS users), 'CHI' for generating a seperate .chi file by the
#   .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
#   output formats. The environment variable DOXYGEN_PAPER_SIZE may be
#   specified to override the default 'a4wide' paper size.
#
#   By default, HTML, PDF and PS documentation is generated as this seems to
#   be the most popular and portable combination. MAN pages created by
#   Doxygen are usually problematic, though by picking an appropriate subset
#   and doing some massaging they might be better than nothing. CHM and RTF
#   are specific for MS (note that you can't generate both HTML and CHM at
#   the same time). The XML is rather useless unless you apply specialized
#   post-processing to it.
#
#   The macros mainly control the default state of the feature. The use can
#   override the default by specifying --enable or --disable. The macros
#   ensure that contradictory flags are not given (e.g.,
#   --enable-doxygen-html and --enable-doxygen-chm,
#   --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
#   feature will be automatically disabled (with a warning) if the required
#   programs are missing.
#
#   Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
#   with the following parameters: a one-word name for the project for use
#   as a filename base etc., an optional configuration file name (the
#   default is 'Doxyfile', the same as Doxygen's default), and an optional
#   output directory name (the default is 'doxygen-doc').
#
#   Automake Support
#
#   The following is a template aminclude.am file for use with Automake.
#   Make targets and variables values are controlled by the various
#   DX_COND_* conditionals set by autoconf.
#
#   The provided targets are:
#
#     doxygen-doc: Generate all doxygen documentation.
#
#     doxygen-run: Run doxygen, which will generate some of the
#                  documentation (HTML, CHM, CHI, MAN, RTF, XML)
#                  but will not do the post processing required
#                  for the rest of it (PS, PDF, and some MAN).
#
#     doxygen-man: Rename some doxygen generated man pages.
#
#     doxygen-ps:  Generate doxygen PostScript documentation.
#
#     doxygen-pdf: Generate doxygen PDF documentation.
#
#   Note that by default these are not integrated into the automake targets.
#   If doxygen is used to generate man pages, you can achieve this
#   integration by setting man3_MANS to the list of man pages generated and
#   then adding the dependency:
#
#     $(man3_MANS): doxygen-doc
#
#   This will cause make to run doxygen and generate all the documentation.
#
#   The following variable is intended for use in Makefile.am:
#
#     DX_CLEANFILES = everything to clean.
#
#   Then add this variable to MOSTLYCLEANFILES.

# 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.
