  33. # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  34. # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
  35. # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
  36. #
  37. # Of course, Automake must honor this variable whenever it calls a
  38. # tool from the auxiliary directory. The problem is that $srcdir (and
  39. # therefore $ac_aux_dir as well) can be either absolute or relative,
  40. # depending on how configure is run. This is pretty annoying, since
  41. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  42. # source directory, any form will work fine, but in subdirectories a
  43. # relative path needs to be adjusted first.
  44. #
  45. # $ac_aux_dir/missing
  46. # fails when called from a subdirectory if $ac_aux_dir is relative
  47. # $top_srcdir/$ac_aux_dir/missing
  48. # fails if $ac_aux_dir is absolute,
  49. # fails when called from a subdirectory in a VPATH build with
  50. # a relative $ac_aux_dir
  51. #
  52. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  53. # are both prefixed by $srcdir. In an in-source build this is usually
  54. # harmless because $srcdir is `.', but things will broke when you
  55. # start a VPATH build or use an absolute $srcdir.
  56. #
  57. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  58. # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
  59. # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  60. # and then we would define $MISSING as
  61. # MISSING="\${SHELL} $am_aux_dir/missing"
  62. # This will work as long as MISSING is not called from configure, because
  63. # unfortunately $(top_srcdir) has no meaning in configure.
  64. # However there are other variables, like CC, which are often used in
  65. # configure, and could therefore not use this "fixed" $ac_aux_dir.
  66. #
  67. # Another solution, used here, is to always expand $ac_aux_dir to an
  68. # absolute PATH. The drawback is that using absolute paths prevent a
  69. # configured tree to be moved without reconfiguration.
