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