# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
182 |
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to |
183 |
# `$srcdir', `$srcdir/..', or `$srcdir/../..'. |
184 |
# |
185 |
# Of course, Automake must honor this variable whenever it calls a |
186 |
# tool from the auxiliary directory. The problem is that $srcdir (and |
187 |
# therefore $ac_aux_dir as well) can be either absolute or relative, |
188 |
# depending on how configure is run. This is pretty annoying, since |
189 |
# it makes $ac_aux_dir quite unusable in subdirectories: in the top |
190 |
# source directory, any form will work fine, but in subdirectories a |
191 |
# relative path needs to be adjusted first. |
192 |
# |
193 |
# $ac_aux_dir/missing |
194 |
# fails when called from a subdirectory if $ac_aux_dir is relative |
195 |
# $top_srcdir/$ac_aux_dir/missing |
196 |
# fails if $ac_aux_dir is absolute, |
197 |
# fails when called from a subdirectory in a VPATH build with |
198 |
# a relative $ac_aux_dir |
199 |
# |
200 |
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
201 |
# are both prefixed by $srcdir. In an in-source build this is usually |
202 |
# harmless because $srcdir is `.', but things will broke when you |
203 |
# start a VPATH build or use an absolute $srcdir. |
204 |
# |
205 |
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
206 |
# iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
207 |
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
208 |
# and then we would define $MISSING as |
209 |
# MISSING="\${SHELL} $am_aux_dir/missing" |
210 |
# This will work as long as MISSING is not called from configure, because |
211 |
# unfortunately $(top_srcdir) has no meaning in configure. |
212 |
# However there are other variables, like CC, which are often used in |
213 |
# configure, and could therefore not use this "fixed" $ac_aux_dir. |
214 |
# |
215 |
# Another solution, used here, is to always expand $ac_aux_dir to an |
216 |
