In other projects, it is set to 69# '$srcdir', '$srcdir/..', or '$srcdir/../..'. 70# 71# Of course, Automake must honor this variable whenever it calls a 72# tool from the auxiliary directory. The problem is that $srcdir (and 73# therefore $ac_aux_dir as well) can be either absolute or relative, 74# depending on how configure is run. This is pretty annoying, since 75# it makes $ac_aux_dir quite unusable in subdirectories: in the top 76# source directory, any form will work fine, but in subdirectories a 77# relative path needs to be adjusted first. 78# 79# $ac_aux_dir/missing 80# fails when called from a subdirectory if $ac_aux_dir is relative 81# $top_srcdir/$ac_aux_dir/missing 82# fails if $ac_aux_dir is absolute, 83# fails when called from a subdirectory in a VPATH build with 84# a relative $ac_aux_dir 85# 86# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 87# are both prefixed by $srcdir. In an in-source build this is usually 88# harmless because $srcdir is '.', but things will broke when you 89# start a VPATH build or use an absolute $srcdir. 90# 91# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 92# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 93# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 94# and then we would define $MISSING as 95# MISSING="\${SHELL} $am_aux_dir/missing" 96# This will work as long as MISSING is not called from configure, because 97# unfortunately $(top_srcdir) has no meaning in configure. 98# However there are other variables, like CC, which are often used in 99# configure, and could therefore not use this "fixed" $ac_aux_dir. 100# 101# Another solution, used here, is to always expand $ac_aux_dir to an 102# absolute PATH.
