In other projects, it is set to 43# `$srcdir', `$srcdir/..', or `$srcdir/../..'. 44# 45# Of course, Automake must honor this variable whenever it calls a 46# tool from the auxiliary directory. The problem is that $srcdir (and 47# therefore $ac_aux_dir as well) can be either absolute or relative, 48# depending on how configure is run. This is pretty annoying, since 49# it makes $ac_aux_dir quite unusable in subdirectories: in the top 50# source directory, any form will work fine, but in subdirectories a 51# relative path needs to be adjusted first. 52# 53# $ac_aux_dir/missing 54# fails when called from a subdirectory if $ac_aux_dir is relative 55# $top_srcdir/$ac_aux_dir/missing 56# fails if $ac_aux_dir is absolute, 57# fails when called from a subdirectory in a VPATH build with 58# a relative $ac_aux_dir 59# 60# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 61# are both prefixed by $srcdir. In an in-source build this is usually 62# harmless because $srcdir is `.', but things will broke when you 63# start a VPATH build or use an absolute $srcdir. 64# 65# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 66# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 67# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 68# and then we would define $MISSING as 69# MISSING="\${SHELL} $am_aux_dir/missing" 70# This will work as long as MISSING is not called from configure, because 71# unfortunately $(top_srcdir) has no meaning in configure. 72# However there are other variables, like CC, which are often used in 73# configure, and could therefore not use this "fixed" $ac_aux_dir. 74# 75# Another solution, used here, is to always expand $ac_aux_dir to an 76# absolute PATH.
