# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
65
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
66
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
68
# Of course, Automake must honor this variable whenever it calls a
69
# tool from the auxiliary directory. The problem is that $srcdir (and
70
# therefore $ac_aux_dir as well) can be either absolute or relative,
71
# depending on how configure is run. This is pretty annoying, since
72
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
73
# source directory, any form will work fine, but in subdirectories a
74
# relative path needs to be adjusted first.
77
# fails when called from a subdirectory if $ac_aux_dir is relative
78
# $top_srcdir/$ac_aux_dir/missing
79
# fails if $ac_aux_dir is absolute,
80
# fails when called from a subdirectory in a VPATH build with
81
# a relative $ac_aux_dir
83
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
84
# are both prefixed by $srcdir. In an in-source build this is usually
85
# harmless because $srcdir is `.', but things will broke when you
86
# start a VPATH build or use an absolute $srcdir.
88
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
89
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
90
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
91
# and then we would define $MISSING as
92
# MISSING="\${SHELL} $am_aux_dir/missing"
93
# This will work as long as MISSING is not called from configure, because
94
# unfortunately $(top_srcdir) has no meaning in configure.
95
# However there are other variables, like CC, which are often used in
96
# configure, and could therefore not use this "fixed" $ac_aux_dir.
98
# Another solution, used here, is to always expand $ac_aux_dir to an
99
# absolute PATH. The drawback is that using absolute paths prevent a
100
# configured tree to be moved without reconfiguration.
