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 77 # relative path needs to be adjusted first. 78 # 79 # $ac_aux_dir/missing 80 # fails when called from a subdirectory if $ac_aux_dir is relative 81 # $top_srcdir/$ac_aux_dir/missing 82 # fails if $ac_aux_dir is absolute, 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 88 # harmless because $srcdir is '.', but things will broke when you 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//*\(.*\)"` 94 # and then we would define $MISSING as 95 # MISSING="\${SHELL} $am_aux_dir/missing" 96 # This will work as long as MISSING is not called from configure, because 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 102 # absolute PATH.
