Tinyos 第三版Make系统

1.make系统安装

cd tools
./Bootstrap
./configure
make
sudo make install

2.make系统结构

3.第三版Makerules文件部分解析

 #  Allow users to specify additional directories to find .target, .extra, and
 #  .rules files. This allows for platforms to be stored in separate repositories
 #  and still compile against the main TinyOS code.
 #
 #  To use this feature, set the environment variable TINYOS_ROOT_DIR_ADDITIONAL
 #  to a space or colon separated list of additional paths to make folders you would
 #  like the make system to search.
 #
 #  Make expects space seperated lists, but ':' seperated is easier to read.  We
 #  convert ':' to ' ' below so Make is happy.
 #
 ROOT_DIR_ADDITIONAL = $(subst :, ,$(TINYOS_ROOT_DIR_ADDITIONAL))
 TOSMAKE_PATH = $(addsuffix /support/make,$(ROOT_DIR_ADDITIONAL))
 TOSMAKE_PATH += $(TINYOS_MAKE_DIR)

添加附加的make目录。以“：”分隔开。

 #  Also determine the path for all TinyOS OS directories that may have code in
 #  them. This makes out-of-tree builds and multiple TinyOS code trees very easy
 #  to manage. All relevant folders will automatically be included to the call to
 #  nescc.
 TOSMAKE_OS_DIR_ALL = $(addsuffix /tos,$(ROOT_DIR_ADDITIONAL)) $(TINYOS_OS_DIR)

 # Create identifying flags for the particular application, user, timestamp, etc.
 IDENT_FLAGS := $(shell tos-ident-flags "$(COMPONENT)")
 CFLAGS += $(IDENT_FLAGS)

第五行定义了全部make路径的变量。8-9行定义了指定目标组件的参数。

 #  Set the rules that expand PFLAGS (which have %T in them) to the PFLAGS that
 #  nescc sees when it compiles.
 TOSDIR_OPTS = $(addprefix --tosdir ,$(TOSMAKE_OS_DIR_ALL))
 ADD_SIM_DIRS = $(if $(filter sim sim-fast sim-sf,$(GOALS)),--sim,)
 NESC_PFLAGS = $(shell tos-sub-tosdir $(TOSDIR_OPTS) $(ADD_SIM_DIRS) $(PFLAGS) $(TOSMAKE_PFLAGS_STD_INCLUDE))

此段代码是获取nesc编译参数中的路径参数，其中tos-sub-tosdir是创建nescc路径命令。使用以下命令查询：

tos-sub-tosdir --help

 # Colors
 ifndef TOSMAKE_NO_COLOR
 NO_COLOR=\x1b[0m
 OK_COLOR=\x1b[;01m
 ERROR_COLOR=\x1b[;01m
 WARN_COLOR=\x1b[;01m
 INFO_COLOR=\x1b[;01m
 endif

 OK_STRING=$(OK_COLOR)[OK]$(NO_COLOR)
 ERROR_STRING=$(ERROR_COLOR)[ERROR]$(NO_COLOR)
 WARN_STRING=$(WARN_COLOR)[WARNING]$(NO_COLOR)
 INFO_STRING=$(INFO_COLOR)[INFO]$(NO_COLOR)

此段代码是指定了OK，ERROR等的显示颜色设置。
