In other projects, it is set to 66# `$srcdir', `$srcdir/..', or `$srcdir/../..'. 67# 68# Of course, Automake must honor this variable whenever it calls a 69# tool from the auxiliary directory. The problem is that $srcdir (and 70# therefore $ac_aux_dir as well) can be either absolute or relative, 71# depending on how configure is run. This is pretty annoying, since 72# it makes $ac_aux_dir quite unusable in subdirectories: in the top 73# source directory, any form will work fine, but in subdirectories a 74# relative path needs to be adjusted first. 75# 76# $ac_aux_dir/missing 77# fails when called from a subdirectory if $ac_aux_dir is relative 78# $top_srcdir/$ac_aux_dir/missing 79# fails if $ac_aux_dir is absolute, 80# fails when called from a subdirectory in a VPATH build with 81# a relative $ac_aux_dir 82# 83# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 84# are both prefixed by $srcdir. In an in-source build this is usually 85# harmless because $srcdir is `.', but things will broke when you 86# start a VPATH build or use an absolute $srcdir. 87# 88# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 89# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 90# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 91# and then we would define $MISSING as 92# MISSING="\${SHELL} $am_aux_dir/missing" 93# This will work as long as MISSING is not called from configure, because 94# unfortunately $(top_srcdir) has no meaning in configure. 95# However there are other variables, like CC, which are often used in 96# configure, and could therefore not use this "fixed" $ac_aux_dir. 97# 98# Another solution, used here, is to always expand $ac_aux_dir to an 99# absolute PATH.
