67# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
22c6a0d0 68# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
69# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
3a479287 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
22c6a0d0 88# harmless because $srcdir is '.', but things will broke when you
3a479287 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. The drawback is that using absolute paths prevent a
103# configured tree to be moved without reconfiguration.
