3.第三版Makerules文件部分解析
1 # Allow users to specify additional directories to find .target, .extra, and 2 # .rules files. This allows for platforms to be stored in separate repositories 3 # and still compile against the main TinyOS code. 4 # 5 # To use this feature, set the environment variable TINYOS_ROOT_DIR_ADDITIONAL 6 # to a space or colon separated list of additional paths to make folders you would 7 # like the make system to search. 8 # 9 # Make expects space seperated lists, but ':' seperated is easier to read. We 10 # convert ':' to ' ' below so Make is happy. 11 # 12 ROOT_DIR_ADDITIONAL = $(subst :, ,$(TINYOS_ROOT_DIR_ADDITIONAL)) 13 TOSMAKE_PATH = $(addsuffix /support/make,$(ROOT_DIR_ADDITIONAL)) 14 TOSMAKE_PATH += $(TINYOS_MAKE_DIR)
添加附加的make目录。以“：”分隔开。
1 # Also determine the path for all TinyOS OS directories that may have code in 2 # them. This makes out-of-tree builds and multiple TinyOS code trees very easy 3 # to manage. All relevant folders will automatically be included to the call to 4 # nescc. 5 TOSMAKE_OS_DIR_ALL = $(addsuffix /tos,$(ROOT_DIR_ADDITIONAL)) $(TINYOS_OS_DIR) 6 7 # Create identifying flags for the particular application, user, timestamp, etc. 8 IDENT_FLAGS := $(shell tos-ident-flags "$(COMPONENT)") 9 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。
1 # Set the rules that expand PFLAGS (which have %T in them) to the PFLAGS that 2 # nescc sees when it compiles. 3 TOSDIR_OPTS = $(addprefix --tosdir ,$(TOSMAKE_OS_DIR_ALL)) 4 ADD_SIM_DIRS = $(if $(filter sim sim-fast sim-sf,$(GOALS)),--sim,) 5 NESC_PFLAGS = $(shell tos-sub-tosdir $(TOSDIR_OPTS) $(ADD_SIM_DIRS) $(PFLAGS) $(TOSMAKE_PFLAGS_STD_INCLUDE))
此段代码是获取nesc编译参数中的路径参数，其中tos-sub-tosdir是创建nescc路径命令。使用以下命令查询：
tos-sub-tosdir --help
1 # Colors 2 ifndef TOSMAKE_NO_COLOR 3 NO_COLOR=x1b[0m 4 OK_COLOR=x1b[32;01m 5 ERROR_COLOR=x1b[31;01m 6 WARN_COLOR=x1b[33;01m 7 INFO_COLOR=x1b[34;01m 8 endif 9 10 OK_STRING=$(OK_COLOR)[OK]$(NO_COLOR) 11 ERROR_STRING=$(ERROR_COLOR)[ERROR]$(NO_COLOR) 12 WARN_STRING=$(WARN_COLOR)[WARNING]$(NO_COLOR) 13 INFO_STRING=$(INFO_COLOR)[INFO]$(NO_COLOR)
此段代码是指定了OK，ERROR等的显示颜色设置。
