1 | - | 70 | # |
71 | # Of course, Automake must honor this variable whenever it calls a |

72 | # tool from the auxiliary directory. The problem is that $srcdir (and |
||
73 | # therefore $ac_aux_dir as well) can be either absolute or relative, |
||
74 | # depending on how configure is run. This is pretty annoying, since |
||
75 | # it makes $ac_aux_dir quite unusable in subdirectories: in the top |
||
76 | # source directory, any form will work fine, but in subdirectories a |

83 | # fails when called from a subdirectory in a VPATH build with |
||
84 | # a relative $ac_aux_dir |
||
85 | # |

86 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
||
87 | # are both prefixed by $srcdir. In an in-source build this is usually |
||
2005 | jag | 88 | # harmless because $srcdir is '.', but things will broke when you |
1 | - | 89 | # start a VPATH build or use an absolute $srcdir. |
90 | # |
||
91 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
||
92 | # iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
||
93 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |

95 | # MISSING="\${SHELL} $am_aux_dir/missing" |

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

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

99 | # configure, and could therefore not use this "fixed" $ac_aux_dir. |

100 | # |

101 | # Another solution, used here, is to always expand $ac_aux_dir to an |
