# -----------------------------------------------------------------------------
|
||||
# DESCRIPTION:
|
||||
# Provides a set of targets to build a C, C++ and/or Assembly application
|
||||
# via the AVR-GCC compiler.
|
||||
# -----------------------------------------------------------------------------
|
||||
# TARGETS:
|
||||
#
|
||||
# size - List built application size
|
||||
# symbol-sizes - Print application symbols from the binary ELF
|
||||
# file as a list sorted by size in bytes
|
||||
# all - Build application and list size
|
||||
# lib - Build and archive source files into a library
|
||||
# elf - Build application ELF debug object file
|
||||
# bin - Build application BIN binary object file
|
||||
# hex - Build application HEX object file
|
||||
# lss - Build application LSS assembly listing file
|
||||
# clean - Remove all project intermediary and binary
|
||||
# output files
|
||||
# mostlyclean - Remove intermediary output files, but
|
||||
# preserve binaries
|
||||
# <filename>.s - Compile C/C++ source file into an assembly file
|
||||
# for manual code inspection

# decrease binary size (note: can cause link
|
||||
# failures on systems with an unpatched binutils)
|
||||
# OBJDIR - Directory for the output object and dependency
|
||||
# files; if equal to ".", the output files will
|
||||
# be generated in the same folder as the sources
|
||||

|
||||
