30 # Individual makefiles set:

33 # SOURCES (*) list of source files
34 # LIBS libraries to link with
35 # DEFS compiler defines
36 # EXTRA_CFLAGS additional flags to pass to C compiler
37 # LINKER_SCRIPT linker script
38 # PRE_DEPEND targets required for dependency check
40 # BINARY (/) binary output name (like appname)
41 # LIBRARY (/) library output name (like libname)
43 # EXTRA_OUTPUT additional output targets
44 # EXTRA_CLEAN additional cleanup targets
46 # POSIX_COMPAT set to 'y' to use POSIX compatibility layer
48 # Optionally, for a binary:
49 # STATIC_NEEDED set to 'y' for init binaries, will build statically
51 # STATIC_ONLY set to 'y' if binary cannot be linked dynamically
52 # (e.g. uses thread-local variables)

55 # SLIBRARY Name with full version, e.g. libfoo.so.0.0
56 # LSONAME Soname / name with short version, e.g. libfoo.so.0
58 # (x) required variables
59 # (/) exactly one of the variables must be defined
