In other projects, it is set to 74# `$srcdir', `$srcdir/..', or `$srcdir/../..'. 75# 76# Of course, Automake must honor this variable whenever it calls a 77# tool from the auxiliary directory. The problem is that $srcdir (and 78# therefore $ac_aux_dir as well) can be either absolute or relative, 79# depending on how configure is run. This is pretty annoying, since 80# it makes $ac_aux_dir quite unusable in subdirectories: in the top 81# source directory, any form will work fine, but in subdirectories a 82# relative path needs to be adjusted first. 83# 84# $ac_aux_dir/missing 85# fails when called from a subdirectory if $ac_aux_dir is relative 86# $top_srcdir/$ac_aux_dir/missing 87# fails if $ac_aux_dir is absolute, 88# fails when called from a subdirectory in a VPATH build with 89# a relative $ac_aux_dir 90# 91# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 92# are both prefixed by $srcdir. In an in-source build this is usually 93# harmless because $srcdir is `.', but things will broke when you 94# start a VPATH build or use an absolute $srcdir. 95# 96# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 97# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 98# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 99# and then we would define $MISSING as 100# MISSING="\${SHELL} $am_aux_dir/missing" 101# This will work as long as MISSING is not called from configure, because 102# unfortunately $(top_srcdir) has no meaning in configure. 103# However there are other variables, like CC, which are often used in 104# configure, and could therefore not use this "fixed" $ac_aux_dir. 105# 106# Another solution, used here, is to always expand $ac_aux_dir to an 107# absolute PATH.
