188 |
|

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 |

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" |
