2 # Rules for NuttX binaries compilation of C, C++ and assembler
3 # sources using GNU toolchain.
5 # Interface to other rules:
6 # kernel_HEADERS .. list of the kernel-space public header files
7 # kernel_MODULES .. list of the kernel side modules/applications
10 # NUTTX_EXPORT - export directory of NuttX build
11 # it should contain subdirectories:
12 # arch build include libs registry startup)
13 # LIB_DIR - directory where compiled libraries are stored
14 # OBJS_DIR - directory where intermediate files (.o, .map, ...) are stored
15 # INCLUDE_DIR - where includes can be found
16 # from config.omk or Makefile.omk
17 # CROSS_COMPILE - target architecture tools prefix
18 # TARGET_ARCH, DEBUG, OPTIMIZE, DEFS - forms CFLAGS
19 # from base: SOURCES_DIR
20 # from Makefile.omk: lib_LOADLIBES
21 # xxx_PROGBUILTIN - list of builtin programs linked into final system image
22 # when "all" is used then all programs provided by build are linked
23 # xxx_PROGBUILTIN_EXCLUDE - list of builtin user or NuttX provided programs which are excluded
24 # xxx_KMODBUILTIN - list of builtin programs linked into final system image
27 # SOURCES - all the source files that needs to be compiled (except for shared library sources)
28 # SOLIB_SOURCES - all the source files that needs to be compiled for a shared library
29 # OBJ_EXT - extension of object files
30 # LIB_EXT - extension of library files
31 # LIB_PREF - prefix for library files
32 # ASM_EXT - extension of assembler sources
35 # COMPILER_DEFS_template - definitions that should be defined before
36 # the following templates can be used. The input variables needs to be
37 # defined before evaluating this template
39 # COMPILE_c_o_template, COMPILE_cc_o_template, COMPILE_S_o_template -
40 # templates that create rules for compilation of sources
42 # PROGRAM_template, LIBRARY_template, SOLIB_template - templates that
43 # create rules for compilation of a program, library and shared
44 # library. The rules can use rules produced by COMPILE_xxx_template.
