cannam@167 70 #
cannam@167 71 # Of course, Automake must honor this variable whenever it calls a
cannam@167 72 # tool from the auxiliary directory. The problem is that $srcdir (and
cannam@167 73 # therefore $ac_aux_dir as well) can be either absolute or relative,
cannam@167 74 # depending on how configure is run. This is pretty annoying, since
cannam@167 75 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
cannam@167 76 # source directory, any form will work fine, but in subdirectories a
cannam@167 77 # relative path needs to be adjusted first.

cannam@167 82 # fails if $ac_aux_dir is absolute,
cannam@167 83 # fails when called from a subdirectory in a VPATH build with
cannam@167 84 # a relative $ac_aux_dir
cannam@167 85 #
cannam@167 86 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
cannam@167 87 # are both prefixed by $srcdir. In an in-source build this is usually
cannam@167 88 # harmless because $srcdir is '.', but things will broke when you
cannam@167 89 # start a VPATH build or use an absolute $srcdir.
cannam@167 90 #
cannam@167 91 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
cannam@167 92 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
cannam@167 93 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
cannam@167 94 # and then we would define $MISSING as
cannam@167 95 # MISSING="\${SHELL} $am_aux_dir/missing"
cannam@167 96 # This will work as long as MISSING is not called from configure, because
cannam@167 97 # unfortunately $(top_srcdir) has no meaning in configure.
cannam@167 98 # However there are other variables, like CC, which are often used in
cannam@167 99 # configure, and could therefore not use this "fixed" $ac_aux_dir.
cannam@167 100 #
cannam@167 101 # Another solution, used here, is to always expand $ac_aux_dir to an
cannam@167 102 # absolute PATH. The drawback is that using absolute paths prevent a
cannam@167 103 # configured tree to be moved without reconfiguration.
