246 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
247 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
248 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
250 # Of course, Automake must honor this variable whenever it calls a
251 # tool from the auxiliary directory. The problem is that $srcdir (and
252 # therefore $ac_aux_dir as well) can be either absolute or relative,
253 # depending on how configure is run. This is pretty annoying, since
254 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
255 # source directory, any form will work fine, but in subdirectories a
256 # relative path needs to be adjusted first.
258 # $ac_aux_dir/missing
259 # fails when called from a subdirectory if $ac_aux_dir is relative
260 # $top_srcdir/$ac_aux_dir/missing
261 # fails if $ac_aux_dir is absolute,
262 # fails when called from a subdirectory in a VPATH build with
263 # a relative $ac_aux_dir
265 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
266 # are both prefixed by $srcdir. In an in-source build this is usually
267 # harmless because $srcdir is `.', but things will broke when you
268 # start a VPATH build or use an absolute $srcdir.
270 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
271 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
272 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
273 # and then we would define $MISSING as
274 # MISSING="\${SHELL} $am_aux_dir/missing"
275 # This will work as long as MISSING is not called from configure, because
276 # unfortunately $(top_srcdir) has no meaning in configure.
277 # However there are other variables, like CC, which are often used in
278 # configure, and could therefore not use this "fixed" $ac_aux_dir.
280 # Another solution, used here, is to always expand $ac_aux_dir to an
