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

46# Optionally, for a binary:
47# STATIC_NEEDED set to 'y' for init binaries, will build statically
48# linked version
49# STATIC_ONLY set to 'y' if binary cannot be linked dynamically
50# (e.g. uses thread-local variables)

52# Optionally, for a libary:
53# SLIBRARY Name with full version, e.g. libfoo.so.0.0
54# LSONAME Soname / name with short version, e.g. libfoo.so.0
55#
56# (x) required variables
57# (/) exactly one of the variables must be defined
