# Makefile-Include for compiling templates (prog.mk, lib.mk)
# Makefile-Include for binary and lib directories
# Definitions for building the Makefile.inc, building dependencies,
# compiler configuration.
#
# If SYSTEM is defined and we do not clean, we generate Makefile.inc. This file
# holds the dependencies of the targets. Is also contains the definitions of
# variables holding the objects of the related targets. In a multiple
# architecture makefile, Makefile.inc will be built in arch-specific subdirs,
# like the other components built.
#
# Most compiler- and linker-flag variables are defined in such a way that
# using them in the rule will expand all the target- and
# architecture-specific definitions.
#
# The relink-rule is defined in this file.
#
# The dependencies for compiling files are defined here, the dep-files are
# generated with names .(source-file).d for .c, .cc and .S-files.
#
# Clean-rules are defined here.

# Variables Section
#
# There is a hierarchy on defining variables depending on the targets they
# refer to: Most standard-Make Variables are supported. This includes
# LDFLAGS - options for ld, defined in prog.mk and lib.mk
# CPPFLAGS - options for the c preprocessor, included in CFLAGS
# CFLAGS - options for the c compiler
# CXXFLAGS - options for the c++ compiler
# FFLAGS - options for the fortran compiler
# ASFLAGS - options for the assembler
#
# Additionally, the following variables are supported:
# SRC_C, SRC_CC, SRC_F, SRC_S - .c, .cc, .f90, .S source files
# LIBS - additional libs to link (with -l), including paths (-L)
# IDL - interface definition files
# TARGET - targets to be built
#
# These variables will be used for all operations with the corresponding
# file types. More specific description is possible by using variables with
# added specifications. These specifications include a referred element and
# the architecture, both optional but in this order, separated by
# underscores. The referred element for CPPFLAGS, CFLAGS, CXXFLAGS and
# ASFLAGS is the source file. For the other variables, it is one of the
# target files. The TARGET variable can only be postfixed by an
# architecture.
# The specific variables will be used for the target and the referred element
# given in the name, additionally to the more general ones.
#
# Example for a valid specifications:
# SRC_C_libxverbose.a = verbose.c - ar's verbose.o into libxverbose.a, but
# not in other libs in the TARGET var.
include $(L4DIR)/mk/modes.inc
# select the variable specified in $(1) from the current architecture and
# mode. Fall back to "all" architecture if no specific version exists.
