655# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
656# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
657# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
658#
659# Of course, Automake must honor this variable whenever it calls a
660# tool from the auxiliary directory. The problem is that $srcdir (and
661# therefore $ac_aux_dir as well) can be either absolute or relative,
662# depending on how configure is run. This is pretty annoying, since
663# it makes $ac_aux_dir quite unusable in subdirectories: in the top
664# source directory, any form will work fine, but in subdirectories a
665# relative path needs to be adjusted first.
666#
667# $ac_aux_dir/missing
668# fails when called from a subdirectory if $ac_aux_dir is relative
669# $top_srcdir/$ac_aux_dir/missing
670# fails if $ac_aux_dir is absolute,
671# fails when called from a subdirectory in a VPATH build with
672# a relative $ac_aux_dir
673#
674# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
675# are both prefixed by $srcdir. In an in-source build this is usually
676# harmless because $srcdir is `.', but things will broke when you
677# start a VPATH build or use an absolute $srcdir.
678#
679# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
680# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
681# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
682# and then we would define $MISSING as
683# MISSING="\${SHELL} $am_aux_dir/missing"
684# This will work as long as MISSING is not called from configure, because
685# unfortunately $(top_srcdir) has no meaning in configure.
686# However there are other variables, like CC, which are often used in
687# configure, and could therefore not use this "fixed" $ac_aux_dir.
688#
689# Another solution, used here, is to always expand $ac_aux_dir to an
690# absolute PATH. The drawback is that using absolute paths prevent a
691# configured tree to be moved without reconfiguration.
