   2 #  Make rules for determining the dependencies between source files.
   3 #
   4 #  This file is intended for use in a Makefile via the include directive, e.g.
   5 #
   6 #      include $(BUID_DIR)/depend_rules.mk
   7 #
   8 #  It may also be include by other rule files in this directory.
   9 #
  10 #  These rules rely upon proper setting of OBJS and SRC_EXTENSIONS.

  21 #  RULES for creating the source code dependencies.
  22 #
  23 #  These are typically used to implement the rules depend and clean_depend
  24 #  in other make rule files.
  25 #
  26 #  'generic_depend' creates the dependencies and appends them to a separate
  27 #      file in the same directory as the source code, called .depend.
  28 #      Depend uses some customized logic to determine the name of the source
  29 #      code file associated with each object file in OBJS.  This means that we
  30 #      can mix source code extensions in the same library (e.g. use C and C++
  31 #      source interchangeably).  See compile_rules.mk for supported file name
  32 #      extensions for C and C++ development.
  33 #
  34 #  'generic_clean_depend' removes the dependencies file .depend.
