# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
67
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
68
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
70
# Of course, Automake must honor this variable whenever it calls a
71
# tool from the auxiliary directory. The problem is that $srcdir (and
72
# therefore $ac_aux_dir as well) can be either absolute or relative,
73
# depending on how configure is run. This is pretty annoying, since
74
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
75
# source directory, any form will work fine, but in subdirectories a
76
# relative path needs to be adjusted first.
79
# fails when called from a subdirectory if $ac_aux_dir is relative
80
# $top_srcdir/$ac_aux_dir/missing
81
# fails if $ac_aux_dir is absolute,
82
# fails when called from a subdirectory in a VPATH build with
83
# a relative $ac_aux_dir
85
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
86
# are both prefixed by $srcdir. In an in-source build this is usually
87
# harmless because $srcdir is `.', but things will broke when you
88
# start a VPATH build or use an absolute $srcdir.
90
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
91
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
92
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
93
# and then we would define $MISSING as
94
# MISSING="\${SHELL} $am_aux_dir/missing"
95
# This will work as long as MISSING is not called from configure, because
96
# unfortunately $(top_srcdir) has no meaning in configure.
97
# However there are other variables, like CC, which are often used in
98
# configure, and could therefore not use this "fixed" $ac_aux_dir.
100
# Another solution, used here, is to always expand $ac_aux_dir to an
101
# absolute PATH. The drawback is that using absolute paths prevent a
102
# configured tree to be moved without reconfiguration.

# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
1708
# Of course, Automake must honor this variable whenever it calls a
1709
# tool from the auxiliary directory. The problem is that $srcdir (and
1710
# therefore $ac_aux_dir as well) can be either absolute or relative,
1711
# depending on how configure is run. This is pretty annoying, since
1712
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
1713
# source directory, any form will work fine, but in subdirectories a
1714
# relative path needs to be adjusted first.

# fails when called from a subdirectory if $ac_aux_dir is relative

# $top_srcdir/$ac_aux_dir/missing

# fails if $ac_aux_dir is absolute,
1720
# fails when called from a subdirectory in a VPATH build with
1721
# a relative $ac_aux_dir
1723
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1724
# are both prefixed by $srcdir. In an in-source build this is usually
1725
# harmless because $srcdir is `.', but things will broke when you
1726
# start a VPATH build or use an absolute $srcdir.
1728
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1729
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
1730
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1731
# and then we would define $MISSING as
1732
# MISSING="\${SHELL} $am_aux_dir/missing"
1733
# This will work as long as MISSING is not called from configure, because
1734
# unfortunately $(top_srcdir) has no meaning in configure.
1735
# However there are other variables, like CC, which are often used in
1736
# configure, and could therefore not use this "fixed" $ac_aux_dir.
1738
# Another solution, used here, is to always expand $ac_aux_dir to an
