  56. # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  57. # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
  58. # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
  59. #
  60. # Of course, Automake must honor this variable whenever it calls a
  61. # tool from the auxiliary directory. The problem is that $srcdir (and
  62. # therefore $ac_aux_dir as well) can be either absolute or relative,
  63. # depending on how configure is run. This is pretty annoying, since
  64. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  65. # source directory, any form will work fine, but in subdirectories a
  66. # relative path needs to be adjusted first.
  67. #
  68. # $ac_aux_dir/missing
  69. # fails when called from a subdirectory if $ac_aux_dir is relative
  70. # $top_srcdir/$ac_aux_dir/missing
  71. # fails if $ac_aux_dir is absolute,
  72. # fails when called from a subdirectory in a VPATH build with
  73. # a relative $ac_aux_dir
  74. #
  75. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  76. # are both prefixed by $srcdir. In an in-source build this is usually
  77. # harmless because $srcdir is `.', but things will broke when you
  78. # start a VPATH build or use an absolute $srcdir.
  79. #
  80. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  81. # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
  82. # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  83. # and then we would define $MISSING as
  84. # MISSING="\${SHELL} $am_aux_dir/missing"
  85. # This will work as long as MISSING is not called from configure, because
  86. # unfortunately $(top_srcdir) has no meaning in configure.
  87. # However there are other variables, like CC, which are often used in
  88. # configure, and could therefore not use this "fixed" $ac_aux_dir.
  89. #
  90. # Another solution, used here, is to always expand $ac_aux_dir to an
  91. # absolute PATH. The drawback is that using absolute paths prevent a
  92. # configured tree to be moved without reconfiguration.
