87# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
[44f44617]88# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
89# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
[a77e7b5]90#
91# Of course, Automake must honor this variable whenever it calls a
92# tool from the auxiliary directory. The problem is that $srcdir (and
93# therefore $ac_aux_dir as well) can be either absolute or relative,
94# depending on how configure is run. This is pretty annoying, since
95# it makes $ac_aux_dir quite unusable in subdirectories: in the top
96# source directory, any form will work fine, but in subdirectories a
97# relative path needs to be adjusted first.
98#
99# $ac_aux_dir/missing
100# fails when called from a subdirectory if $ac_aux_dir is relative
101# $top_srcdir/$ac_aux_dir/missing
102# fails if $ac_aux_dir is absolute,
103# fails when called from a subdirectory in a VPATH build with
104# a relative $ac_aux_dir
105#
106# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
107# are both prefixed by $srcdir. In an in-source build this is usually
[44f44617]108# harmless because $srcdir is '.', but things will broke when you
[a77e7b5]109# start a VPATH build or use an absolute $srcdir.
110#
111# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
112# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
113# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
114# and then we would define $MISSING as
115# MISSING="\${SHELL} $am_aux_dir/missing"
116# This will work as long as MISSING is not called from configure, because
117# unfortunately $(top_srcdir) has no meaning in configure.
118# However there are other variables, like CC, which are often used in
119# configure, and could therefore not use this "fixed" $ac_aux_dir.
120#
121# Another solution, used here, is to always expand $ac_aux_dir to an
122# absolute PATH. The drawback is that using absolute paths prevent a
123# configured tree to be moved without reconfiguration.
