# 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 |
|
|

# $top_srcdir/$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" |

# unfortunately $(top_srcdir) has no meaning in configure. |
| 212 |

# However there are other variables, like CC, which are often used in |
