classes/siteinfo.bbclass

   1 # This class exists to provide information about the targets that
   2 # may be needed by other classes and/or recipes. If you add a new
   3 # target this will probably need to be updated.
   4
   5 #
   6 # Returns information about 'what' for the named target 'target'
   7 # where 'target' == "<arch>-<os>"
   8 #
   9 # 'what' can be one of
  10 # * target: Returns the target name ("<arch>-<os>")
  11 # * endianess: Return "be" for big endian targets, "le" for little endian
  12 # * bits: Returns the bit size of the target, either "32" or "64"
  13 # * libc: Returns the name of the c library used by the target
  14 #
  15 # It is an error for the target not to exist.
  16 # If 'what' doesn't exist then an empty value is returned
