67d4401354Smrg# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
68f591e195Smrg# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
69f591e195Smrg# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
70d4401354Smrg#
71d4401354Smrg# Of course, Automake must honor this variable whenever it calls a
72d4401354Smrg# tool from the auxiliary directory.  The problem is that $srcdir (and
73d4401354Smrg# therefore $ac_aux_dir as well) can be either absolute or relative,
74d4401354Smrg# depending on how configure is run.  This is pretty annoying, since
75d4401354Smrg# it makes $ac_aux_dir quite unusable in subdirectories: in the top
76d4401354Smrg# source directory, any form will work fine, but in subdirectories a
77d4401354Smrg# relative path needs to be adjusted first.
78d4401354Smrg#
79d4401354Smrg# $ac_aux_dir/missing
80d4401354Smrg#    fails when called from a subdirectory if $ac_aux_dir is relative
81d4401354Smrg# $top_srcdir/$ac_aux_dir/missing
82d4401354Smrg#    fails if $ac_aux_dir is absolute,
83d4401354Smrg#    fails when called from a subdirectory in a VPATH build with
84d4401354Smrg#          a relative $ac_aux_dir
85d4401354Smrg#
86d4401354Smrg# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
87d4401354Smrg# are both prefixed by $srcdir.  In an in-source build this is usually
88f591e195Smrg# harmless because $srcdir is '.', but things will broke when you
89d4401354Smrg# start a VPATH build or use an absolute $srcdir.
90d4401354Smrg#
91d4401354Smrg# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
92d4401354Smrg# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
93d4401354Smrg#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
94d4401354Smrg# and then we would define $MISSING as
95d4401354Smrg#   MISSING="\${SHELL} $am_aux_dir/missing"
96d4401354Smrg# This will work as long as MISSING is not called from configure, because
97d4401354Smrg# unfortunately $(top_srcdir) has no meaning in configure.
98d4401354Smrg# However there are other variables, like CC, which are often used in
99d4401354Smrg# configure, and could therefore not use this "fixed" $ac_aux_dir.
100d4401354Smrg#
101d4401354Smrg# Another solution, used here, is to always expand $ac_aux_dir to an
102d4401354Smrg# absolute PATH.  The drawback is that using absolute paths prevent a
103d4401354Smrg# configured tree to be moved without reconfiguration.
