147 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
148 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
149 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
150 #
151 # Of course, Automake must honor this variable whenever it calls a
152 # tool from the auxiliary directory. The problem is that $srcdir (and
153 # therefore $ac_aux_dir as well) can be either absolute or relative,
154 # depending on how configure is run. This is pretty annoying, since
155 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
156 # source directory, any form will work fine, but in subdirectories a
157 # relative path needs to be adjusted first.
158 #
159 # $ac_aux_dir/missing
160 # fails when called from a subdirectory if $ac_aux_dir is relative
161 # $top_srcdir/$ac_aux_dir/missing
162 # fails if $ac_aux_dir is absolute,
163 # fails when called from a subdirectory in a VPATH build with
164 # a relative $ac_aux_dir
165 #
166 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
167 # are both prefixed by $srcdir. In an in-source build this is usually
168 # harmless because $srcdir is '.', but things will broke when you
169 # start a VPATH build or use an absolute $srcdir.
170 #
171 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
172 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
173 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
174 # and then we would define $MISSING as
175 # MISSING="\${SHELL} $am_aux_dir/missing"
176 # This will work as long as MISSING is not called from configure, because
177 # unfortunately $(top_srcdir) has no meaning in configure.
178 # However there are other variables, like CC, which are often used in
179 # configure, and could therefore not use this "fixed" $ac_aux_dir.
180 #
181 # Another solution, used here, is to always expand $ac_aux_dir to an
182 # absolute PATH. The drawback is that using absolute paths prevent a
183 # configured tree to be moved without reconfiguration.
