Chris@42 67 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
Chris@42 68 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
Chris@42 69 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
Chris@42 70 #
Chris@42 71 # Of course, Automake must honor this variable whenever it calls a
Chris@42 72 # tool from the auxiliary directory. The problem is that $srcdir (and
Chris@42 73 # therefore $ac_aux_dir as well) can be either absolute or relative,
Chris@42 74 # depending on how configure is run. This is pretty annoying, since
Chris@42 75 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
Chris@42 76 # source directory, any form will work fine, but in subdirectories a
Chris@42 77 # relative path needs to be adjusted first.
Chris@42 78 #
Chris@42 79 # $ac_aux_dir/missing
Chris@42 80 # fails when called from a subdirectory if $ac_aux_dir is relative
Chris@42 81 # $top_srcdir/$ac_aux_dir/missing
Chris@42 82 # fails if $ac_aux_dir is absolute,
Chris@42 83 # fails when called from a subdirectory in a VPATH build with
Chris@42 84 # a relative $ac_aux_dir
Chris@42 85 #
Chris@42 86 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
Chris@42 87 # are both prefixed by $srcdir. In an in-source build this is usually
Chris@42 88 # harmless because $srcdir is '.', but things will broke when you
Chris@42 89 # start a VPATH build or use an absolute $srcdir.
Chris@42 90 #
Chris@42 91 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
Chris@42 92 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
Chris@42 93 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
Chris@42 94 # and then we would define $MISSING as
Chris@42 95 # MISSING="\${SHELL} $am_aux_dir/missing"
Chris@42 96 # This will work as long as MISSING is not called from configure, because
Chris@42 97 # unfortunately $(top_srcdir) has no meaning in configure.
Chris@42 98 # However there are other variables, like CC, which are often used in
Chris@42 99 # configure, and could therefore not use this "fixed" $ac_aux_dir.
Chris@42 100 #
Chris@42 101 # Another solution, used here, is to always expand $ac_aux_dir to an
Chris@42 102 # absolute PATH. The drawback is that using absolute paths prevent a
Chris@42 103 # configured tree to be moved without reconfiguration.
