adamc@1141 72 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

adamc@1141 74 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
adamc@1141 75 #
adamc@1141 76 # Of course, Automake must honor this variable whenever it calls a
adamc@1141 77 # tool from the auxiliary directory. The problem is that $srcdir (and
adamc@1141 78 # therefore $ac_aux_dir as well) can be either absolute or relative,
adamc@1141 79 # depending on how configure is run. This is pretty annoying, since
adamc@1141 80 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
adamc@1141 81 # source directory, any form will work fine, but in subdirectories a
adamc@1141 82 # relative path needs to be adjusted first.
adamc@1141 83 #
adamc@1141 84 # $ac_aux_dir/missing
adamc@1141 85 # fails when called from a subdirectory if $ac_aux_dir is relative
adamc@1141 86 # $top_srcdir/$ac_aux_dir/missing
adamc@1141 87 # fails if $ac_aux_dir is absolute,
adamc@1141 88 # fails when called from a subdirectory in a VPATH build with
adamc@1141 89 # a relative $ac_aux_dir
adamc@1141 90 #
adamc@1141 91 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
adamc@1141 92 # are both prefixed by $srcdir. In an in-source build this is usually
adamc@1141 93 # harmless because $srcdir is `.', but things will broke when you
adamc@1141 94 # start a VPATH build or use an absolute $srcdir.
adamc@1141 95 #
adamc@1141 96 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
adamc@1141 97 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
adamc@1141 98 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
adamc@1141 99 # and then we would define $MISSING as
adamc@1141 100 # MISSING="\${SHELL} $am_aux_dir/missing"
adamc@1141 101 # This will work as long as MISSING is not called from configure, because
adamc@1141 102 # unfortunately $(top_srcdir) has no meaning in configure.
adamc@1141 103 # However there are other variables, like CC, which are often used in
adamc@1141 104 # configure, and could therefore not use this "fixed" $ac_aux_dir.
adamc@1141 105 #
adamc@1141 106 # Another solution, used here, is to always expand $ac_aux_dir to an
adamc@1141 107 # absolute PATH. The drawback is that using absolute paths prevent a
adamc@1141 108 # configured tree to be moved without reconfiguration.
