90 | # |

91 | # Of course, Automake must honor this variable whenever it calls a |

93 | # therefore $ac_aux_dir as well) can be either absolute or relative, |
---|
94 | # depending on how configure is run. This is pretty annoying, since |
---|
95 | # it makes $ac_aux_dir quite unusable in subdirectories: in the top |
---|
96 | # source directory, any form will work fine, but in subdirectories a |

97 | # relative path needs to be adjusted first. |

---|
102 | # fails if $ac_aux_dir is absolute, |
---|
103 | # fails when called from a subdirectory in a VPATH build with |
---|
104 | # a relative $ac_aux_dir |
---|
105 | # |
---|
106 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
---|
107 | # are both prefixed by $srcdir. In an in-source build this is usually |
---|
108 | # harmless because $srcdir is '.', but things will broke when you |
---|
109 | # start a VPATH build or use an absolute $srcdir. |
---|
110 | # |
---|
111 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
---|
112 | # iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
---|
113 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
---|
114 | # and then we would define $MISSING as |
---|
115 | # MISSING="\${SHELL} $am_aux_dir/missing" |

116 | # This will work as long as MISSING is not called from configure, because |

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

119 | # configure, and could therefore not use this "fixed" $ac_aux_dir. |
---|
120 | # |
---|
121 | # Another solution, used here, is to always expand $ac_aux_dir to an |
