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