universe@48 67 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
universe@48 68 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
universe@48 69 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
universe@48 70 #
universe@48 71 # Of course, Automake must honor this variable whenever it calls a
universe@48 72 # tool from the auxiliary directory. The problem is that $srcdir (and
universe@48 73 # therefore $ac_aux_dir as well) can be either absolute or relative,
universe@48 74 # depending on how configure is run. This is pretty annoying, since
universe@48 75 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
universe@48 76 # source directory, any form will work fine, but in subdirectories a
universe@48 77 # relative path needs to be adjusted first.
universe@48 78 #
universe@48 79 # $ac_aux_dir/missing
universe@48 80 # fails when called from a subdirectory if $ac_aux_dir is relative
universe@48 81 # $top_srcdir/$ac_aux_dir/missing
universe@48 82 # fails if $ac_aux_dir is absolute,
universe@48 83 # fails when called from a subdirectory in a VPATH build with
universe@48 84 # a relative $ac_aux_dir
universe@48 85 #
universe@48 86 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
universe@48 87 # are both prefixed by $srcdir. In an in-source build this is usually
universe@48 88 # harmless because $srcdir is '.', but things will broke when you
universe@48 89 # start a VPATH build or use an absolute $srcdir.
universe@48 90 #
universe@48 91 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
universe@48 92 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
universe@48 93 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
universe@48 94 # and then we would define $MISSING as
universe@48 95 # MISSING="\${SHELL} $am_aux_dir/missing"
universe@48 96 # This will work as long as MISSING is not called from configure, because
universe@48 97 # unfortunately $(top_srcdir) has no meaning in configure.
universe@48 98 # However there are other variables, like CC, which are often used in
universe@48 99 # configure, and could therefore not use this "fixed" $ac_aux_dir.
universe@48 100 #
universe@48 101 # Another solution, used here, is to always expand $ac_aux_dir to an
universe@48 102 # absolute PATH. The drawback is that using absolute paths prevent a
universe@48 103 # configured tree to be moved without reconfiguration.
