346 | # Of course, Automake must honor this variable whenever it calls a | |

349 | # depending on how configure is run. This is pretty annoying, since | |
350 | # it makes $ac_aux_dir quite unusable in subdirectories: in the top | |
351 | # source directory, any form will work fine, but in subdirectories a | |
352 | # relative path needs to be adjusted first. | |
353 | # | |
354 | # $ac_aux_dir/missing | |
355 | # fails when called from a subdirectory if $ac_aux_dir is relative | |
356 | # $top_srcdir/$ac_aux_dir/missing | |
357 | # fails if $ac_aux_dir is absolute, | |
358 | # fails when called from a subdirectory in a VPATH build with | |
359 | # a relative $ac_aux_dir | |
360 | # | |
361 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | |
362 | # are both prefixed by $srcdir. In an in-source build this is usually | |
89fde9ac | 363 | # harmless because $srcdir is '.', but things will broke when you |
fe000966 DM |
364 | # start a VPATH build or use an absolute $srcdir. |
365 | # | |
366 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, | |
367 | # iff we strip the leading $srcdir from $ac_aux_dir. That would be: | |
368 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` | |

371 | # This will work as long as MISSING is not called from configure, because | |
372 | # unfortunately $(top_srcdir) has no meaning in configure. | |
373 | # However there are other variables, like CC, which are often used in | |
374 | # configure, and could therefore not use this "fixed" $ac_aux_dir. | |
375 | # | |
376 | # Another solution, used here, is to always expand $ac_aux_dir to an | |
