#
# SYNOPSIS
#
# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
#
# DESCRIPTION
#
# Check for the presence of an --enable-debug option to configure, with
# the specified default value used when the option is not present. Return
# the value in the variable $ax_enable_debug.
#
# Specifying 'yes' adds '-g -O0' to the compilation flags for all
# languages. Specifying 'info' adds '-g' to the compilation flags.
# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
# the linking flags. Otherwise, nothing is added.
#
# Define the variables listed in the second argument if debug is enabled,
# defaulting to no variables. Defines the variables listed in the third
# argument if debug is disabled, defaulting to NDEBUG. All lists of
# variables should be space-separated.
#
# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
# Should be invoked prior to any AC_PROG_* compiler checks.
#
# IS-RELEASE can be used to change the default to 'no' when making a
# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
# macro, there is no need to pass this parameter.
#
# AX_IS_RELEASE([git-directory])

#
# 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.
