The problem is that $srcdir (and 1468 # therefore $ac_aux_dir as well) can be either absolute or relative, 1469 # depending on how configure is run. This is pretty annoying, since 1470 # it makes $ac_aux_dir quite unusable in subdirectories: in the top 1471 # source directory, any form will work fine, but in subdirectories a 1472 # relative path needs to be adjusted first. 1473 # 1474 # $ac_aux_dir/missing 1475 # fails when called from a subdirectory if $ac_aux_dir is relative 1476 # $top_srcdir/$ac_aux_dir/missing 1477 # fails if $ac_aux_dir is absolute, 1478 # fails when called from a subdirectory in a VPATH build with 1479 # a relative $ac_aux_dir 1480 # 1481 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir 1482 # are both prefixed by $srcdir. In an in-source build this is usually 1483 # harmless because $srcdir is '.', but things will broke when you 1484 # start a VPATH build or use an absolute $srcdir. 1485 # 1486 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 1487 # iff we strip the leading $srcdir from $ac_aux_dir. That would be: 1488 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*$.*$"` 1489 # and then we would define $MISSING as 1490 # MISSING="\${SHELL} $am_aux_dir/missing" 1491 # This will work as long as MISSING is not called from configure, because 1492 # unfortunately $(top_srcdir) has no meaning in configure. 1493 # However there are other variables, like CC, which are often used in 1494 # configure, and could therefore not use this "fixed" $ac_aux_dir. 1495 # 1496 # Another solution, used here, is to always expand $ac_aux_dir to an 1497 # absolute PATH.
