70 1.1 christos #
71 1.1 christos # Of course, Automake must honor this variable whenever it calls a
72 1.1 christos # tool from the auxiliary directory. The problem is that $srcdir (and
73 1.1 christos # therefore $ac_aux_dir as well) can be either absolute or relative,
74 1.1 christos # depending on how configure is run. This is pretty annoying, since
75 1.1 christos # it makes $ac_aux_dir quite unusable in subdirectories: in the top
76 1.1 christos # source directory, any form will work fine, but in subdirectories a
77 1.1 christos # relative path needs to be adjusted first.

79 1.1 christos # $ac_aux_dir/missing
80 1.1 christos # fails when called from a subdirectory if $ac_aux_dir is relative
81 1.1 christos # $top_srcdir/$ac_aux_dir/missing
82 1.1 christos # fails if $ac_aux_dir is absolute,
83 1.1 christos # fails when called from a subdirectory in a VPATH build with
84 1.1 christos # a relative $ac_aux_dir
85 1.1 christos #
86 1.1 christos # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
87 1.1 christos # are both prefixed by $srcdir. In an in-source build this is usually
88 1.1.1.4 christos # harmless because $srcdir is '.', but things will broke when you
89 1.1 christos # start a VPATH build or use an absolute $srcdir.
90 1.1 christos #
91 1.1 christos # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
92 1.1 christos # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
93 1.1 christos # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
94 1.1 christos # and then we would define $MISSING as
95 1.1 christos # MISSING="\${SHELL} $am_aux_dir/missing"
96 1.1 christos # This will work as long as MISSING is not called from configure, because
97 1.1 christos # unfortunately $(top_srcdir) has no meaning in configure.
98 1.1 christos # However there are other variables, like CC, which are often used in
99 1.1 christos # configure, and could therefore not use this "fixed" $ac_aux_dir.
100 1.1 christos #
101 1.1 christos # Another solution, used here, is to always expand $ac_aux_dir to an
102 1.1 christos # absolute PATH. The drawback is that using absolute paths prevent a
