# Makefile fragment for C and C++ libraries for applications and modules
#
# $Id$
#
# This makefile provides the following phony targets:
#
#    all_libs  export_hdrs  export_libs
#
#
# This fragment uses the following macros set by the master makefile.
#
#
# COMPONENT          (the name of the component)
# TARGET       (opt) (the leafname of the primary target - otherwise ${COMPONENT})
# LIBRARY      (opt) (the leafname of the application library - otherwise ${TARGET})
# LIBRARYZM    (opt) (the leafname of the module library - otherwise ${LIBRARY}zm)
# LIBRARYD     (opt) (the leafname of the debug app library - otherwise ${LIBRARY}d)
# LIBRARYDZM   (opt) (the leafname of the debug module library - otherwise ${LIBRARY}dzm)
# LIBRARIES    (opt) (libraries to build/export - otherwise ${LIBRARY} and ${LIBRARYZM})
# LIBEXT       (opt) (subdir or filename extension for library files - otherwise o)
# EXPDIR       (opt) (the target directory - otherwise <Lib$Dir>.${TARGET})
# DIRS         (opt) (stamp object for directory creation - otherwise o._dirs)
# HDRS         (opt) (header files to export, no h. prefix - otherwise ${TARGET})
# ASMHDRS      (opt) (assembly header files to export, no Hdr. prefix - otherwise none)
# OBJS               (object files, no o. or oz. prefixes)
# DBG_OBJS     (opt) (debug build object files, no o. or oz. prefixes - otherwise ${OBJS})
# APP_OBJS     (opt) (object files for application version - otherwise derived from ${OBJS})
# APP_DBG_OBJS (opt) (object files for debug app version - otherwise derived from ${DBG_OBJS})
# MOD_OBJS     (opt) (object files for module version - otherwise derived from ${OBJS})
# MOD_DBG_OBJS (opt) (object files for debug module version - otherwise derived from ${DBG_OBJS})
# CUSTOMLIB    (opt) (set to "custom" to override the application library rule)
# CUSTOMLIBZM  (opt) (set to "custom" to override the module library rule)
# CUSTOMLIBD   (opt) (set to "custom" to override the debug application library rule)
# CUSTOMLIBDZM (opt) (set to "custom" to override the debug module library rule)
#
#
# It relies on the following from the build system:
#
#
# PHASE            (export phase discriminator)
#
#
# It relies on the following generic tool macros from the StdTools makefile
#
#
# CP + CPFLAGS     (copy, cp etc.)
# WIPE + WFLAGS    (recursive delete)
# RM               (non-recursive delete)
# AS + ASFLAGS     (assembler)
# MKDIR            (cdir/mkdir -p)
# ECHO
# AR + ARFLAGS     (libfile/ar)
# TOUCH            (create/touch)
# NOP
#
#
# It relies on the following from the StdRules makefile
#
#
# .c.o  .c.oz  .c++.o  .cpp.o  .c++.oz  .c++.oz  .s.o  .s.oz
#
#
# It relies on the following from the DbgRules makefile
#
#
# CDFLAGS  C++DFLAGS  ASDFLAGS
# .c.od  .c.odz  .c++.od  .cpp.od  .c++.odz  .cpp.odz  .s.od  .s.odz
