64# 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/../..'.
252b5132 67#
ab509236

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.
75#
76# $ac_aux_dir/missing
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
82#
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.
87#
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.
252b5132 97#
ab509236
L
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.
