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