# Rules for compilation of C, C++ and assembler sources using GNU
# toolchain.

# Interface to other rules:

# Input variables:
# LIB_DIR - directory where compiled libraries are stored
# OBJS_DIR - directory where intermediate files (.o, .map, ...) are stored
# INCLUDE_DIR - where includes can be found
# from config.omk or Makefile.omk
# CROSS_COMPILE - 
# TARGET_ARCH, DEBUG, OPTIMIZE, DEFS - forms CFLAGS
# from base: SOURCES_DIR
# from Makefile.omk: lib_LOADLIBES

# Output variables:
# SOURCES - all the source files that needs to be compiled (except for shared library sources)
# SOLIB_SOURCES - all the source files that needs to be compiled for a shared library
# OBJ_EXT - extension of object files
# LIB_EXT - extension of library files
# LIB_PREF - prefix for library files
# ASM_EXT - extension of assembler sources

# Templates:
# COMPILER_DEFS_template - definitions that should be defined before
# the following templates can be used. The input variables needs to be
# defined before evaluating this template

# COMPILE_c_o_template, COMPILE_cc_o_template, COMPILE_S_o_template -
# templates that create rules for compilation of sources

# CMETRIC_o_h_template - FIXME

# PROGRAM_template, LIBRARY_template, SOLIB_template - templates that
# create rules for compilation of a program, library and shared
# library. The rules can use rules produced by COMPILE_xxx_template.
