| 411 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets | |
| 412 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to | |
| 413 # '$srcdir', '$srcdir/..', or '$srcdir/../..'. | |
| 414 # | |
| 415 # Of course, Automake must honor this variable whenever it calls a | |
| 416 # tool from the auxiliary directory. The problem is that $srcdir (and | |
| 417 # therefore $ac_aux_dir as well) can be either absolute or relative, | |
| 418 # depending on how configure is run. This is pretty annoying, since | |
| 419 # it makes $ac_aux_dir quite unusable in subdirectories: in the top | |
| 420 # source directory, any form will work fine, but in subdirectories a | |
| 421 # relative path needs to be adjusted first. | |
| 422 # | |
| 423 # $ac_aux_dir/missing | |
| 424 # fails when called from a subdirectory if $ac_aux_dir is relative | |
| 425 # $top_srcdir/$ac_aux_dir/missing | |
| 426 # fails if $ac_aux_dir is absolute, | |
| 427 # fails when called from a subdirectory in a VPATH build with | |
| 428 # a relative $ac_aux_dir | |
| 429 # | |
| 430 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | |
| 431 # are both prefixed by $srcdir. In an in-source build this is usually | |
| 432 # harmless because $srcdir is '.', but things will broke when you | |
| 433 # start a VPATH build or use an absolute $srcdir. | |
| 434 # | |
| 435 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, | |
| 436 # iff we strip the leading $srcdir from $ac_aux_dir. That would be: | |
| 437 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` | |
| 438 # and then we would define $MISSING as | |
| 439 # MISSING="\${SHELL} $am_aux_dir/missing" | |
| 440 # This will work as long as MISSING is not called from configure, because | |
| 441 # unfortunately $(top_srcdir) has no meaning in configure. | |
| 442 # However there are other variables, like CC, which are often used in | |
| 443 # configure, and could therefore not use this "fixed" $ac_aux_dir. | |
| 444 # | |
| 445 # Another solution, used here, is to always expand $ac_aux_dir to an | |
| 446 # absolute PATH. The drawback is that using absolute paths prevent a | |
| 447 # configured tree to be moved without reconfiguration. | |
