ea04106b
AX
91#
92# Of course, Automake must honor this variable whenever it calls a
93# tool from the auxiliary directory. The problem is that $srcdir (and
94# therefore $ac_aux_dir as well) can be either absolute or relative,
95# depending on how configure is run. This is pretty annoying, since
96# it makes $ac_aux_dir quite unusable in subdirectories: in the top
97# source directory, any form will work fine, but in subdirectories a
98# relative path needs to be adjusted first.
99#
100# $ac_aux_dir/missing
101# fails when called from a subdirectory if $ac_aux_dir is relative
102# $top_srcdir/$ac_aux_dir/missing
103# fails if $ac_aux_dir is absolute,
104# fails when called from a subdirectory in a VPATH build with
105# a relative $ac_aux_dir
106#
107# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
108# are both prefixed by $srcdir. In an in-source build this is usually
cae5b340 109# harmless because $srcdir is `.', but things will broke when you
ea04106b
AX
110# start a VPATH build or use an absolute $srcdir.
111#
112# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
113# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
114# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
115# and then we would define $MISSING as
116# MISSING="\${SHELL} $am_aux_dir/missing"
117# This will work as long as MISSING is not called from configure, because
118# unfortunately $(top_srcdir) has no meaning in configure.
119# However there are other variables, like CC, which are often used in
120# configure, and could therefore not use this "fixed" $ac_aux_dir.
121#
122# Another solution, used here, is to always expand $ac_aux_dir to an
123# absolute PATH. The drawback is that using absolute paths prevent a
124# configured tree to be moved without reconfiguration.
