88 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
89 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
90 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
92 # Of course, Automake must honor this variable whenever it calls a
93 # tool from the auxiliary directory. The problem is that $srcdir (and
94 # therefore $ac_aux_dir as well) can be either absolute or relative,
95 # depending on how configure is run. This is pretty annoying, since
96 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
97 # source directory, any form will work fine, but in subdirectories a
98 # relative path needs to be adjusted first.
100 # $ac_aux_dir/missing
101 # fails when called from a subdirectory if $ac_aux_dir is relative
102 # $top_srcdir/$ac_aux_dir/missing
103 # fails if $ac_aux_dir is absolute,
104 # fails when called from a subdirectory in a VPATH build with
105 # a relative $ac_aux_dir
107 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
108 # are both prefixed by $srcdir. In an in-source build this is usually
109 # harmless because $srcdir is `.', but things will broke when you
110 # start a VPATH build or use an absolute $srcdir.
112 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
113 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
114 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
115 # and then we would define $MISSING as
116 # MISSING="\${SHELL} $am_aux_dir/missing"
117 # This will work as long as MISSING is not called from configure, because
118 # unfortunately $(top_srcdir) has no meaning in configure.
119 # However there are other variables, like CC, which are often used in
120 # configure, and could therefore not use this "fixed" $ac_aux_dir.
122 # Another solution, used here, is to always expand $ac_aux_dir to an
123 # absolute PATH. The drawback is that using absolute paths prevent a
