In other projects, it is set to 85# `$srcdir', `$srcdir/..', or `$srcdir/../..'. 86# 87# Of course, Automake must honor this variable whenever it calls a 88# tool from the auxiliary directory. The problem is that $srcdir (and 89# therefore $ac_aux_dir as well) can be either absolute or relative, 90# depending on how configure is run. This is pretty annoying, since 91# it makes $ac_aux_dir quite unusable in subdirectories: in the top 92# source directory, any form will work fine, but in subdirectories a 93# relative path needs to be adjusted first. 94# 95# $ac_aux_dir/missing 96# fails when called from a subdirectory if $ac_aux_dir is relative 97# $top_srcdir/$ac_aux_dir/missing 98# fails if $ac_aux_dir is absolute, 99# fails when called from a subdirectory in a VPATH build with 100# a relative $ac_aux_dir 101# 102# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 103# are both prefixed by $srcdir. In an in-source build this is usually 104# harmless because $srcdir is `.', but things will broke when you 105# start a VPATH build or use an absolute $srcdir. 106# 107# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 108# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 109# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 110# and then we would define $MISSING as 111# MISSING="\${SHELL} $am_aux_dir/missing" 112# This will work as long as MISSING is not called from configure, because 113# unfortunately $(top_srcdir) has no meaning in configure. 114# However there are other variables, like CC, which are often used in 115# configure, and could therefore not use this "fixed" $ac_aux_dir. 116# 117# Another solution, used here, is to always expand $ac_aux_dir to an 118# absolute PATH.
