adamc@1141 136 #
adamc@1141 137 # Of course, Automake must honor this variable whenever it calls a
adamc@1141 138 # tool from the auxiliary directory. The problem is that $srcdir (and
adamc@1141 139 # therefore $ac_aux_dir as well) can be either absolute or relative,
adamc@1141 140 # depending on how configure is run. This is pretty annoying, since
adamc@1141 141 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
adamc@1141 142 # source directory, any form will work fine, but in subdirectories a
adamc@1141 143 # relative path needs to be adjusted first.
adamc@1141 144 #
adamc@1141 145 # $ac_aux_dir/missing
adamc@1141 146 # fails when called from a subdirectory if $ac_aux_dir is relative
adamc@1141 147 # $top_srcdir/$ac_aux_dir/missing
adamc@1141 148 # fails if $ac_aux_dir is absolute,
adamc@1141 149 # fails when called from a subdirectory in a VPATH build with
adamc@1141 150 # a relative $ac_aux_dir
adamc@1141 151 #
adamc@1141 152 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
adamc@1141 153 # are both prefixed by $srcdir. In an in-source build this is usually
adamc@1141 154 # harmless because $srcdir is `.', but things will broke when you
adamc@1141 155 # start a VPATH build or use an absolute $srcdir.
adamc@1141 156 #
adamc@1141 157 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
adamc@1141 158 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
adamc@1141 159 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
adamc@1141 160 # and then we would define $MISSING as
adamc@1141 161 # MISSING="\${SHELL} $am_aux_dir/missing"
adamc@1141 162 # This will work as long as MISSING is not called from configure, because
adamc@1141 163 # unfortunately $(top_srcdir) has no meaning in configure.
adamc@1141 164 # However there are other variables, like CC, which are often used in
adamc@1141 165 # configure, and could therefore not use this "fixed" $ac_aux_dir.
adamc@1141 166 #
adamc@1141 167 # Another solution, used here, is to always expand $ac_aux_dir to an
adamc@1141 168 # absolute PATH. The drawback is that using absolute paths prevent a
