127 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
128 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
129 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
131 # Of course, Automake must honor this variable whenever it calls a
132 # tool from the auxiliary directory. The problem is that $srcdir (and
133 # therefore $ac_aux_dir as well) can be either absolute or relative,
134 # depending on how configure is run. This is pretty annoying, since
135 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
136 # source directory, any form will work fine, but in subdirectories a
137 # relative path needs to be adjusted first.
139 # $ac_aux_dir/missing
140 # fails when called from a subdirectory if $ac_aux_dir is relative
141 # $top_srcdir/$ac_aux_dir/missing
142 # fails if $ac_aux_dir is absolute,
143 # fails when called from a subdirectory in a VPATH build with
144 # a relative $ac_aux_dir
146 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
147 # are both prefixed by $srcdir. In an in-source build this is usually
148 # harmless because $srcdir is '.', but things will broke when you
149 # start a VPATH build or use an absolute $srcdir.
151 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
152 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
153 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
154 # and then we would define $MISSING as
155 # MISSING="\${SHELL} $am_aux_dir/missing"
156 # This will work as long as MISSING is not called from configure, because
157 # unfortunately $(top_srcdir) has no meaning in configure.
158 # However there are other variables, like CC, which are often used in
159 # configure, and could therefore not use this "fixed" $ac_aux_dir.
161 # Another solution, used here, is to always expand $ac_aux_dir to an
162 # absolute PATH. The drawback is that using absolute paths prevent a
