The problem is that $srcdir (and 78 # therefore $ac_aux_dir as well) can be either absolute or relative, 79 # depending on how configure is run. This is pretty annoying, since 80 # it makes $ac_aux_dir quite unusable in subdirectories: in the top 81 # source directory, any form will work fine, but in subdirectories a 82 # relative path needs to be adjusted first. 83 # 84 # $ac_aux_dir/missing 85 # fails when called from a subdirectory if $ac_aux_dir is relative 86 # $top_srcdir/$ac_aux_dir/missing 87 # fails if $ac_aux_dir is absolute, 88 # fails when called from a subdirectory in a VPATH build with 89 # a relative $ac_aux_dir 90 # 91 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir 92 # are both prefixed by $srcdir. In an in-source build this is usually 93 # harmless because $srcdir is `.', but things will broke when you 94 # start a VPATH build or use an absolute $srcdir. 95 # 96 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 97 # iff we strip the leading $srcdir from $ac_aux_dir.
