In other projects, it is set to 63# `$srcdir', `$srcdir/..', or `$srcdir/../..'. 64# 65# Of course, Automake must honor this variable whenever it calls a 66# tool from the auxiliary directory. The problem is that $srcdir (and 67# therefore $ac_aux_dir as well) can be either absolute or relative, 68# depending on how configure is run. This is pretty annoying, since 69# it makes $ac_aux_dir quite unusable in subdirectories: in the top 70# source directory, any form will work fine, but in subdirectories a 71# relative path needs to be adjusted first. 72# 73# $ac_aux_dir/missing 74# fails when called from a subdirectory if $ac_aux_dir is relative 75# $top_srcdir/$ac_aux_dir/missing 76# fails if $ac_aux_dir is absolute, 77# fails when called from a subdirectory in a VPATH build with 78# a relative $ac_aux_dir 79# 80# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 81# are both prefixed by $srcdir. In an in-source build this is usually 82# harmless because $srcdir is `.', but things will broke when you 83# start a VPATH build or use an absolute $srcdir. 84# 85# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 86# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 87# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 88# and then we would define $MISSING as 89# MISSING="\${SHELL} $am_aux_dir/missing" 90# This will work as long as MISSING is not called from configure, because 91# unfortunately $(top_srcdir) has no meaning in configure. 92# However there are other variables, like CC, which are often used in 93# configure, and could therefore not use this "fixed" $ac_aux_dir. 94# 95# Another solution, used here, is to always expand $ac_aux_dir to an 96# absolute PATH.
