293 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
294 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
295 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
297 # Of course, Automake must honor this variable whenever it calls a
298 # tool from the auxiliary directory. The problem is that $srcdir (and
299 # therefore $ac_aux_dir as well) can be either absolute or relative,
300 # depending on how configure is run. This is pretty annoying, since
301 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
302 # source directory, any form will work fine, but in subdirectories a
303 # relative path needs to be adjusted first.
305 # $ac_aux_dir/missing
306 # fails when called from a subdirectory if $ac_aux_dir is relative
307 # $top_srcdir/$ac_aux_dir/missing
308 # fails if $ac_aux_dir is absolute,
309 # fails when called from a subdirectory in a VPATH build with
310 # a relative $ac_aux_dir
312 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
313 # are both prefixed by $srcdir. In an in-source build this is usually
314 # harmless because $srcdir is `.', but things will broke when you
315 # start a VPATH build or use an absolute $srcdir.
317 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
318 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
319 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
320 # and then we would define $MISSING as
321 # MISSING="\${SHELL} $am_aux_dir/missing"
322 # This will work as long as MISSING is not called from configure, because
323 # unfortunately $(top_srcdir) has no meaning in configure.
324 # However there are other variables, like CC, which are often used in
325 # configure, and could therefore not use this "fixed" $ac_aux_dir.
327 # Another solution, used here, is to always expand $ac_aux_dir to an
