222 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
223 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
224 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
225 #
226 # Of course, Automake must honor this variable whenever it calls a
227 # tool from the auxiliary directory. The problem is that $srcdir (and
228 # therefore $ac_aux_dir as well) can be either absolute or relative,
229 # depending on how configure is run. This is pretty annoying, since
230 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
231 # source directory, any form will work fine, but in subdirectories a
232 # relative path needs to be adjusted first.
233 #
234 # $ac_aux_dir/missing
235 # fails when called from a subdirectory if $ac_aux_dir is relative
236 # $top_srcdir/$ac_aux_dir/missing
237 # fails if $ac_aux_dir is absolute,
238 # fails when called from a subdirectory in a VPATH build with
239 # a relative $ac_aux_dir
240 #
241 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
242 # are both prefixed by $srcdir. In an in-source build this is usually
243 # harmless because $srcdir is `.', but things will broke when you
244 # start a VPATH build or use an absolute $srcdir.
245 #
246 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
247 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
248 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
249 # and then we would define $MISSING as
250 # MISSING="\${SHELL} $am_aux_dir/missing"
251 # This will work as long as MISSING is not called from configure, because
252 # unfortunately $(top_srcdir) has no meaning in configure.
253 # However there are other variables, like CC, which are often used in
254 # configure, and could therefore not use this "fixed" $ac_aux_dir.
255 #
256 # Another solution, used here, is to always expand $ac_aux_dir to an
257 # absolute PATH. The drawback is that using absolute paths prevent a
258 # configured tree to be moved without reconfiguration.
