  51. # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  52. # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
  53. # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
  54. #
  55. # Of course, Automake must honor this variable whenever it calls a
  56. # tool from the auxiliary directory. The problem is that $srcdir (and
  57. # therefore $ac_aux_dir as well) can be either absolute or relative,
  58. # depending on how configure is run. This is pretty annoying, since
  59. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  60. # source directory, any form will work fine, but in subdirectories a
  61. # relative path needs to be adjusted first.
  62. #
  63. # $ac_aux_dir/missing
  64. # fails when called from a subdirectory if $ac_aux_dir is relative
  65. # $top_srcdir/$ac_aux_dir/missing
  66. # fails if $ac_aux_dir is absolute,
  67. # fails when called from a subdirectory in a VPATH build with
  68. # a relative $ac_aux_dir
  69. #
  70. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  71. # are both prefixed by $srcdir. In an in-source build this is usually
  72. # harmless because $srcdir is `.', but things will broke when you
  73. # start a VPATH build or use an absolute $srcdir.
  74. #
  75. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  76. # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
  77. # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  78. # and then we would define $MISSING as
  79. # MISSING="\${SHELL} $am_aux_dir/missing"
  80. # This will work as long as MISSING is not called from configure, because
  81. # unfortunately $(top_srcdir) has no meaning in configure.
  82. # However there are other variables, like CC, which are often used in
  83. # configure, and could therefore not use this "fixed" $ac_aux_dir.
  84. #
  85. # Another solution, used here, is to always expand $ac_aux_dir to an
  86. # absolute PATH. The drawback is that using absolute paths prevent a
  87. # configured tree to be moved without reconfiguration.
