#  Make rules for producing a library module.
#
#  This file is intended for use in Makefile via the include directive, e.g.
#
#      include $(BUILD_DIR)/library_rules.mk
#
#  It is assumed that the environment has been set by sourcing the build
#  resource file (buildrc).
# 
#  This file defines the following rules for library modules:
#
#      all, lib, archive, linked_lib, utest, exe, clean, clean_lib, 
#      clean_depend, depend.

SHELL=/bin/sh

#
#  RULES that can be passed through to subdirectories. 
#
#    Each of these rules executes the rule on this directory, then executes
#    the same rule on each subdirectory specified in SUB_DIRS.
#
#    The rules for this directory are specified as thisdir_<rulename> in
#    this file, e.g. "thisdir_all" implements "make all" for this directory. 
#
#    The SUB_DIRS variable only needs to be set if building of subdirectories
#    is desired.  In this case, the list of subdirectories ($$s) is set to the
#    no-op value of "foobar" to prevent the shell for seeing errors in the 
#    subsequent for loop when SUB_DIRS is not set.

#
#  RULES for building a library.
#
#  - 'lib' builds the library as a shared library.
#  - 'archive' builds the library as an archive library.
#  - 'linked_lib' builds the library as a shared library (if necessary), and
#    links the shared library to its dependent libraries.
#  - Specific library names are built depending on the update status of the
#    library of the same name installed in $(LIB_DEST).
#  - Libraries are built depending on the status of its object files (OBJS)
#
#  NOTE: Shared libraries are linked against the libraries upon which they
#        depend.  This is not possible with archive libraries.

#  RULE for building an executable.
#
#  For library modules, these do nothing, but we define one so that make exe
#  can be passed down to all source directories.
#
exe:
	@echo "make exe does nothing for library modules"

#
#  RULES for cleaning up derived files.
#
#  'clean' removes all objects produced by this file, as well as other 
#      extraneous artifacts of compiling and building libraries.
# 
#      A subsequent make will both recompile the source code and recreate
#      the shared library.  clean also removes files core files and other
#      auxilliary files created during compilation.
#
#  'clean_lib' removes only the libraries, both shared and archive.
#
#      A subsequent make will recreate the shared library from the compiled
#      object files.

#
#  RULES for creating the include dependencies.
#
#  'depend' creates the dependencies and appends them to the end of this file.
#      Depend uses some customized logic to determine the name of the source
#      code file associated with each object file in OBJS.  This means that we
#      can mix source code extensions in the same library (e.g. use C and C++
#      source interchangeably).  See compile_rules.mk for supported file name
#      extensions.
#
#  'clean_depend' removes the dependencies from this file, which makes the
#      Makefile much smaller.  make clean_depend should be done before
#      checking a Makefile into revision control.
