130 1.1 christos #
131 1.1 christos # Of course, Automake must honor this variable whenever it calls a
132 1.1 christos # tool from the auxiliary directory. The problem is that $srcdir (and
133 1.1 christos # therefore $ac_aux_dir as well) can be either absolute or relative,
134 1.1 christos # depending on how configure is run. This is pretty annoying, since
135 1.1 christos # it makes $ac_aux_dir quite unusable in subdirectories: in the top
136 1.1 christos # source directory, any form will work fine, but in subdirectories a
137 1.1 christos # relative path needs to be adjusted first.

142 1.1 christos # fails if $ac_aux_dir is absolute,
143 1.1 christos # fails when called from a subdirectory in a VPATH build with
144 1.1 christos # a relative $ac_aux_dir
145 1.1 christos #
146 1.1 christos # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
147 1.1 christos # are both prefixed by $srcdir. In an in-source build this is usually
148 1.1 christos # harmless because $srcdir is '.', but things will broke when you
149 1.1 christos # start a VPATH build or use an absolute $srcdir.
150 1.1 christos #
151 1.1 christos # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
152 1.1 christos # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
153 1.1 christos # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
154 1.1 christos # and then we would define $MISSING as
155 1.1 christos # MISSING="\${SHELL} $am_aux_dir/missing"
156 1.1 christos # This will work as long as MISSING is not called from configure, because
157 1.1 christos # unfortunately $(top_srcdir) has no meaning in configure.
158 1.1 christos # However there are other variables, like CC, which are often used in
159 1.1 christos # configure, and could therefore not use this "fixed" $ac_aux_dir.
160 1.1 christos #
161 1.1 christos # Another solution, used here, is to always expand $ac_aux_dir to an
162 1.1 christos # absolute PATH. The drawback is that using absolute paths prevent a
