| 182 | # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to |

| 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 |
