  60. # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  61. # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
  62. # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
  63. #
  64. # Of course, Automake must honor this variable whenever it calls a
  65. # tool from the auxiliary directory. The problem is that $srcdir (and
  66. # therefore $ac_aux_dir as well) can be either absolute or relative,
  67. # depending on how configure is run. This is pretty annoying, since
  68. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  69. # source directory, any form will work fine, but in subdirectories a
  70. # relative path needs to be adjusted first.
  71. #
  72. # $ac_aux_dir/missing
  73. # fails when called from a subdirectory if $ac_aux_dir is relative
  74. # $top_srcdir/$ac_aux_dir/missing
  75. # fails if $ac_aux_dir is absolute,
  76. # fails when called from a subdirectory in a VPATH build with
  77. # a relative $ac_aux_dir
  78. #
  79. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  80. # are both prefixed by $srcdir. In an in-source build this is usually
  81. # harmless because $srcdir is `.', but things will broke when you
  82. # start a VPATH build or use an absolute $srcdir.
  83. #
  84. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  85. # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
  86. # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  87. # and then we would define $MISSING as
  88. # MISSING="\${SHELL} $am_aux_dir/missing"
  89. # This will work as long as MISSING is not called from configure, because
  90. # unfortunately $(top_srcdir) has no meaning in configure.
  91. # However there are other variables, like CC, which are often used in
  92. # configure, and could therefore not use this "fixed" $ac_aux_dir.
  93. #
  94. # Another solution, used here, is to always expand $ac_aux_dir to an
  95. # absolute PATH. The drawback is that using absolute paths prevent a
  96. # configured tree to be moved without reconfiguration.
