In other projects, it is set to 68# `$srcdir', `$srcdir/..', or `$srcdir/../..'. 69# 70# Of course, Automake must honor this variable whenever it calls a 71# tool from the auxiliary directory. The problem is that $srcdir (and 72# therefore $ac_aux_dir as well) can be either absolute or relative, 73# depending on how configure is run. This is pretty annoying, since 74# it makes $ac_aux_dir quite unusable in subdirectories: in the top 75# source directory, any form will work fine, but in subdirectories a 76# relative path needs to be adjusted first. 77# 78# $ac_aux_dir/missing 79# fails when called from a subdirectory if $ac_aux_dir is relative 80# $top_srcdir/$ac_aux_dir/missing 81# fails if $ac_aux_dir is absolute, 82# fails when called from a subdirectory in a VPATH build with 83# a relative $ac_aux_dir 84# 85# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 86# are both prefixed by $srcdir. In an in-source build this is usually 87# harmless because $srcdir is `.', but things will broke when you 88# start a VPATH build or use an absolute $srcdir. 89# 90# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 91# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 92# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 93# and then we would define $MISSING as 94# MISSING="\${SHELL} $am_aux_dir/missing" 95# This will work as long as MISSING is not called from configure, because 96# unfortunately $(top_srcdir) has no meaning in configure. 97# However there are other variables, like CC, which are often used in 98# configure, and could therefore not use this "fixed" $ac_aux_dir. 99# 100# Another solution, used here, is to always expand $ac_aux_dir to an 101# absolute PATH.
