| 403 | # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
| 404 | # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to |
| 405 | # '$srcdir', '$srcdir/..', or '$srcdir/../..'. |
| 406 | # |
| 407 | # Of course, Automake must honor this variable whenever it calls a |
| 408 | # tool from the auxiliary directory. The problem is that $srcdir (and |
| 409 | # therefore $ac_aux_dir as well) can be either absolute or relative, |
| 410 | # depending on how configure is run. This is pretty annoying, since |
| 411 | # it makes $ac_aux_dir quite unusable in subdirectories: in the top |
| 412 | # source directory, any form will work fine, but in subdirectories a |
| 413 | # relative path needs to be adjusted first. |
| 414 | # |
| 415 | # $ac_aux_dir/missing |
| 416 | # fails when called from a subdirectory if $ac_aux_dir is relative |
| 417 | # $top_srcdir/$ac_aux_dir/missing |
| 418 | # fails if $ac_aux_dir is absolute, |
| 419 | # fails when called from a subdirectory in a VPATH build with |
| 420 | # a relative $ac_aux_dir |
| 421 | # |
| 422 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
| 423 | # are both prefixed by $srcdir. In an in-source build this is usually |
| 424 | # harmless because $srcdir is '.', but things will broke when you |
| 425 | # start a VPATH build or use an absolute $srcdir. |
| 426 | # |
| 427 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
| 428 | # iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
| 429 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
| 430 | # and then we would define $MISSING as |
| 431 | # MISSING="\${SHELL} $am_aux_dir/missing" |
| 432 | # This will work as long as MISSING is not called from configure, because |
| 433 | # unfortunately $(top_srcdir) has no meaning in configure. |
| 434 | # However there are other variables, like CC, which are often used in |
| 435 | # configure, and could therefore not use this "fixed" $ac_aux_dir. |
| 436 | # |
| 437 | # Another solution, used here, is to always expand $ac_aux_dir to an |
| 438 | # absolute PATH. The drawback is that using absolute paths prevent a |
| 439 | # configured tree to be moved without reconfiguration. |
