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
23 # SOURCES - all the source files that needs to be compiled (except for shared library sources)
24 # SOLIB_SOURCES - all the source files that needs to be compiled for a shared library
25 # OBJ_EXT - extension of object files
26 # LIB_EXT - extension of library files
27 # LIB_PREF - prefix for library files
28 # ASM_EXT - extension of assembler sources
31 # COMPILER_DEFS_template - definitions that should be defined before
32 # the following templates can be used. The input variables needs to be
33 # defined before evaluating this template
35 # COMPILE_c_o_template, COMPILE_cc_o_template, COMPILE_S_o_template -
36 # templates that create rules for compilation of sources
38 # PROGRAM_template, LIBRARY_template, SOLIB_template - templates that
39 # create rules for compilation of a program, library and shared
40 # library. The rules can use rules produced by COMPILE_xxx_template.
