meillo@0 369 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
meillo@0 370 #
meillo@0 371 # Of course, Automake must honor this variable whenever it calls a
meillo@0 372 # tool from the auxiliary directory. The problem is that $srcdir (and
meillo@0 373 # therefore $ac_aux_dir as well) can be either absolute or relative,
meillo@0 374 # depending on how configure is run. This is pretty annoying, since
meillo@0 375 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
meillo@0 376 # source directory, any form will work fine, but in subdirectories a
meillo@0 377 # relative path needs to be adjusted first.
meillo@0 378 #
meillo@0 379 # $ac_aux_dir/missing
meillo@0 380 # fails when called from a subdirectory if $ac_aux_dir is relative
meillo@0 381 # $top_srcdir/$ac_aux_dir/missing
meillo@0 382 # fails if $ac_aux_dir is absolute,
meillo@0 383 # fails when called from a subdirectory in a VPATH build with
meillo@0 384 # a relative $ac_aux_dir
meillo@0 385 #
meillo@0 386 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
meillo@0 387 # are both prefixed by $srcdir. In an in-source build this is usually
meillo@0 388 # harmless because $srcdir is `.', but things will broke when you
meillo@0 389 # start a VPATH build or use an absolute $srcdir.
meillo@0 390 #
meillo@0 391 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
meillo@0 392 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
meillo@0 393 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
meillo@0 394 # and then we would define $MISSING as
meillo@0 395 # MISSING="\${SHELL} $am_aux_dir/missing"
meillo@0 396 # This will work as long as MISSING is not called from configure, because
meillo@0 397 # unfortunately $(top_srcdir) has no meaning in configure.
meillo@0 398 # However there are other variables, like CC, which are often used in
meillo@0 399 # configure, and could therefore not use this "fixed" $ac_aux_dir.
meillo@0 400 #
meillo@0 401 # Another solution, used here, is to always expand $ac_aux_dir to an
meillo@0 402 # absolute PATH. The drawback is that using absolute paths prevent a
