# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
62
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
63
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
65
# Of course, Automake must honor this variable whenever it calls a
66
# tool from the auxiliary directory. The problem is that $srcdir (and
67
# therefore $ac_aux_dir as well) can be either absolute or relative,
68
# depending on how configure is run. This is pretty annoying, since
69
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
70
# source directory, any form will work fine, but in subdirectories a
71
# relative path needs to be adjusted first.
74
# fails when called from a subdirectory if $ac_aux_dir is relative
75
# $top_srcdir/$ac_aux_dir/missing
76
# fails if $ac_aux_dir is absolute,
77
# fails when called from a subdirectory in a VPATH build with
78
# a relative $ac_aux_dir
80
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
81
# are both prefixed by $srcdir. In an in-source build this is usually
82
# harmless because $srcdir is `.', but things will broke when you
83
# start a VPATH build or use an absolute $srcdir.
85
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
86
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
87
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
88
# and then we would define $MISSING as
89
# MISSING="\${SHELL} $am_aux_dir/missing"
90
# This will work as long as MISSING is not called from configure, because
91
# unfortunately $(top_srcdir) has no meaning in configure.
92
# However there are other variables, like CC, which are often used in
93
# configure, and could therefore not use this "fixed" $ac_aux_dir.
95
# Another solution, used here, is to always expand $ac_aux_dir to an
96
# absolute PATH. The drawback is that using absolute paths prevent a
97
# configured tree to be moved without reconfiguration.
