87 1.1 riastrad # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
88 1.1 riastrad # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
89 1.1 riastrad # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
90 1.1 riastrad #
91 1.1 riastrad # Of course, Automake must honor this variable whenever it calls a
92 1.1 riastrad # tool from the auxiliary directory. The problem is that $srcdir (and
93 1.1 riastrad # therefore $ac_aux_dir as well) can be either absolute or relative,
94 1.1 riastrad # depending on how configure is run. This is pretty annoying, since
95 1.1 riastrad # it makes $ac_aux_dir quite unusable in subdirectories: in the top
96 1.1 riastrad # source directory, any form will work fine, but in subdirectories a
97 1.1 riastrad # relative path needs to be adjusted first.
98 1.1 riastrad #
99 1.1 riastrad # $ac_aux_dir/missing
100 1.1 riastrad # fails when called from a subdirectory if $ac_aux_dir is relative
101 1.1 riastrad # $top_srcdir/$ac_aux_dir/missing
102 1.1 riastrad # fails if $ac_aux_dir is absolute,
103 1.1 riastrad # fails when called from a subdirectory in a VPATH build with
104 1.1 riastrad # a relative $ac_aux_dir
105 1.1 riastrad #
106 1.1 riastrad # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
107 1.1 riastrad # are both prefixed by $srcdir. In an in-source build this is usually
108 1.1 riastrad # harmless because $srcdir is '.', but things will broke when you
109 1.1 riastrad # start a VPATH build or use an absolute $srcdir.
110 1.1 riastrad #
111 1.1 riastrad # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
112 1.1 riastrad # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
113 1.1 riastrad # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
114 1.1 riastrad # and then we would define $MISSING as
115 1.1 riastrad # MISSING="\${SHELL} $am_aux_dir/missing"
116 1.1 riastrad # This will work as long as MISSING is not called from configure, because
117 1.1 riastrad # unfortunately $(top_srcdir) has no meaning in configure.
118 1.1 riastrad # However there are other variables, like CC, which are often used in
119 1.1 riastrad # configure, and could therefore not use this "fixed" $ac_aux_dir.
120 1.1 riastrad #
121 1.1 riastrad # Another solution, used here, is to always expand $ac_aux_dir to an
122 1.1 riastrad # absolute PATH. The drawback is that using absolute paths prevent a
