186 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
187 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
188 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
190 # Of course, Automake must honor this variable whenever it calls a
191 # tool from the auxiliary directory. The problem is that $srcdir (and
192 # therefore $ac_aux_dir as well) can be either absolute or relative,
193 # depending on how configure is run. This is pretty annoying, since
194 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
195 # source directory, any form will work fine, but in subdirectories a
196 # relative path needs to be adjusted first.
198 # $ac_aux_dir/missing
199 # fails when called from a subdirectory if $ac_aux_dir is relative
200 # $top_srcdir/$ac_aux_dir/missing
201 # fails if $ac_aux_dir is absolute,
202 # fails when called from a subdirectory in a VPATH build with
203 # a relative $ac_aux_dir
205 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
206 # are both prefixed by $srcdir. In an in-source build this is usually
207 # harmless because $srcdir is '.', but things will broke when you
208 # start a VPATH build or use an absolute $srcdir.
210 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
211 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
212 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
213 # and then we would define $MISSING as
214 # MISSING="\${SHELL} $am_aux_dir/missing"
215 # This will work as long as MISSING is not called from configure, because
216 # unfortunately $(top_srcdir) has no meaning in configure.
217 # However there are other variables, like CC, which are often used in
218 # configure, and could therefore not use this "fixed" $ac_aux_dir.
