| 443 # `$srcdir', `$srcdir/..', or `$srcdir/../..'. | |
| 444 # | |
| 445 # Of course, Automake must honor this variable whenever it calls a | |
| 446 # tool from the auxiliary directory. The problem is that $srcdir (and | |
| 447 # therefore $ac_aux_dir as well) can be either absolute or relative, | |
| 448 # depending on how configure is run. This is pretty annoying, since | |
| 449 # it makes $ac_aux_dir quite unusable in subdirectories: in the top | |
| 450 # source directory, any form will work fine, but in subdirectories a | |
| 451 # relative path needs to be adjusted first. | |
| 452 # | |
| 453 # $ac_aux_dir/missing | |
| 454 # fails when called from a subdirectory if $ac_aux_dir is relative | |
| 455 # $top_srcdir/$ac_aux_dir/missing | |
| 456 # fails if $ac_aux_dir is absolute, | |
| 457 # fails when called from a subdirectory in a VPATH build with | |
| 458 # a relative $ac_aux_dir | |
| 459 # | |
| 460 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | |
| 461 # are both prefixed by $srcdir. In an in-source build this is usually | |
| 462 # harmless because $srcdir is `.', but things will broke when you | |
| 463 # start a VPATH build or use an absolute $srcdir. | |
| 464 # | |
| 465 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, | |
| 466 # iff we strip the leading $srcdir from $ac_aux_dir. That would be: | |
| 467 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` | |
| 468 # and then we would define $MISSING as | |
| 469 # MISSING="\${SHELL} $am_aux_dir/missing" | |
| 470 # This will work as long as MISSING is not called from configure, because | |
| 471 # unfortunately $(top_srcdir) has no meaning in configure. | |
| 472 # However there are other variables, like CC, which are often used in | |
| 473 # configure, and could therefore not use this "fixed" $ac_aux_dir. | |
| 474 # | |
| 475 # Another solution, used here, is to always expand $ac_aux_dir to an | |
| 476 # absolute PATH. The drawback is that using absolute paths prevent a | |
| 477 # configured tree to be moved without reconfiguration. | |
