1.3.1 Makfile中常用变量
1. LITEOSTOPDIR // kernel/liteos_a 2. LITEOSTHIRDPARTY // third_party 3. LITEOS_MK_PATH // kernel/liteos_a/tools/build/mk 4. MK_PATH = $(LITEOSTOPDIR)/tools/build/mk // kernel/liteos_a/tools/build/mk
1.3.2 包含的文件
Makefile里使用include命令包含了很多文件，这些文件又包含了其他文件。
1. STM32MP157
Makefile -include $(LITEOSTOPDIR)/tools/build/config.mk -include $(LITEOSTOPDIR)/tools/build/mk/los_config.mk -include $(LITEOSTOPDIR)/.config include $(LITEOSTOPDIR)/arch/cpu.mk -include $(LITEOSTOPDIR)/arch/arm/arm.mk include $(LITEOSTOPDIR)/platform/bsp.mk include $(LITEOSTOPDIR)/../../vendor/st/stm32mp157/stm32mp157.mk include $(LITEOSTOPDIR)/../../drivers/hdf/lite/hdf_lite.mk include $(LITEOSTOPDIR)/../../vendor/st/hdf/hdf_vendor.mk -include $(LITEOSTOPDIR)/3rdParty/3rdParty.mk -include $(LITEOS_MK_PATH)/liteos_tables_ldflags.mk -include $(LITEOS_MK_PATH)/dynload.mk
2. IMX6ULL
Makefile -include $(LITEOSTOPDIR)/tools/build/config.mk -include $(LITEOSTOPDIR)/tools/build/mk/los_config.mk -include $(LITEOSTOPDIR)/.config include $(LITEOSTOPDIR)/arch/cpu.mk -include $(LITEOSTOPDIR)/arch/arm/arm.mk include $(LITEOSTOPDIR)/platform/bsp.mk include $(LITEOSTOPDIR)/../../vendor/nxp/imx6ull/imx6ull.mk include $(LITEOSTOPDIR)/../../drivers/hdf/lite/hdf_lite.mk include $(LITEOSTOPDIR)/../../vendor/nxp/hdf/hdf_vendor.mk -include $(LITEOSTOPDIR)/3rdParty/3rdParty.mk -include $(LITEOS_MK_PATH)/liteos_tables_ldflags.mk -include $(LITEOS_MK_PATH)/dynload.mk
两个板子的区别：
3. 展开Makefile
把Makefile里被包含的文件都展开，这样便于分析。
我们事先对STM32MP157、IMX6ULL展开了它们的Makefile，结果分别保存在这两个文件里：
Makefile_all_stm32mp157.txt Makefile_all_imx6ull.txt
注意：-include表示有文件就包含，没有文件就不包含。
下面是Makefile_all_stm32mp157.txt

1.3.3 分析make过程
1. 第1个目标
all: $(OUT) $(BUILD) $(LITEOS_TARGET) $(APPS)
2. 目标: OUT
OUT目标：
创建了目录：kernel/liteos_a/imx6ull/lib
把board.ld.S编译成了board.ld，这是链接文件。
# .config文件中， LOSCFG_PLATFORM="imx6ull" OUT = $(LITEOSTOPDIR)/out/$(LITEOS_PLATFORM) $(OUT): $(LITEOS_MENUCONFIG_H) $(HIDE)mkdir -p $(OUT)/lib $(HIDE)$(CC) -I$(LITEOS_PLATFORM_BASE)/include -I$(BOARD_INCLUDE_DIR) \ -E $(LITEOS_PLATFORM_BASE)/board.ld.S \ -o $(LITEOS_PLATFORM_BASE)/board.ld -P
OUT的依赖：LITEOS_MENUCONFIG_H
配置内核，生成头文件autoconf.h。
LITEOS_MENUCONFIG_H = $(LITEOSTOPDIR)/include/generated/autoconf.h KCONFIG_FILE_PATH = $(LITEOSTOPDIR)/Kconfig $(LITEOS_MENUCONFIG_H): ifneq ($(LITEOS_PLATFORM_MENUCONFIG_H), $(wildcard $(LITEOS_PLATFORM_MENUCONFIG_H))) $(HIDE)$(MAKE) genconfig endif genconfig:$(MENUCONFIG_PATH)/conf $(HIDE)mkdir -p include/config include/generated $< --silentoldconfig $(KCONFIG_FILE_PATH) -mv -f $(LITEOS_MENUCONFIG_H) $(LITEOS_PLATFORM_MENUCONFIG_H)
3. 目标: BUILD
创建目录 kernel/liteos_a/out/stm32mp157/obj或kernel/liteos_a/out/imx6ull/obj
OUT = $(LITEOSTOPDIR)/out/$(LITEOS_PLATFORM) BUILD = $(OUT)/obj $(BUILD): $(HIDE)mkdir -p $(BUILD)
4. 目标: LITEOS_TARGET
这是核心，进入子目录执行make，把子目录中的文件链接为一个库。
最后，把这些库链接为liteos内核。
LITEOS_TARGET = liteos $(LITEOS_TARGET): $(__LIBS) $(HIDE)touch $(LOSCFG_ENTRY_SRC) $(HIDE)for dir in $(LITEOS_SUBDIRS); \ do $(MAKE) -C $$dir all || exit 1; \ done $(LD) $(LITEOS_LDFLAGS) $(LITEOS_TABLES_LDFLAGS) $(LITEOS_DYNLDFLAGS) -Map=$(OUT)/$@.map -o $(OUT)/$@ --start-group $(LITEOS_LIBDEP) --end-group # $(SIZE) -t --common $(OUT)/lib/*.a >$(OUT)/$@.objsize $(OBJCOPY) -O binary $(OUT)/$@ $(LITEOS_TARGET_DIR)/$@.bin $(OBJDUMP) -t $(OUT)/$@ |sort >$(OUT)/$@.sym.sorted $(OBJDUMP) -d $(OUT)/$@ >$(OUT)/$@.asm # $(NM) -S --size-sort $(OUT)/$@ >$(OUT)/$@.size
目标：__LIBS
# 没做什么事
__LIBS = libs $(__LIBS): $(OUT) $(CXX_INCLUDE)
命令：$(HIDE)touch $(LOSCFG_ENTRY_SRC)
每次都要编译los_config.c，touch一下
LOSCFG_ENTRY_SRC = $(LITEOSTOPDIR)/kernel/common/los_config.c
命令：进入每个LITEOS_SUBDIRS，执行make
# LIB_SUBDIRS 等于一系列的目录 LIB_SUBDIRS := LIB_SUBDIRS += arch/arm/$(LITEOS_ARCH_ARM) # 就是arch/arm/arm LIB_SUBDIRS += $(PLATFORM_BSP_HISI_BASE) LIB_SUBDIRS += $(LITEOSTOPDIR)/kernel/common LIB_SUBDIRS += kernel/base LIB_SUBDIRS += $(IMX6ULL_BASE_DIR)/board LIB_SUBDIRS += $(IMX6ULL_BASE_DIR)/driver/mtd/common LIB_SUBDIRS += $(IMX6ULL_BASE_DIR)/driver/mtd/spi_nor LIB_SUBDIRS += $(IMX6ULL_BASE_DIR)/driver/imx6ull-fb LIB_SUBDIRS += $(IMX6ULL_BASE_DIR)/driver/imx6ull-uart LIB_SUBDIRS += kernel/extended/cpup LIB_SUBDIRS += lib/libc LIB_SUBDIRS += lib/libsec LIB_SUBDIRS += lib/libscrew LIB_SUBDIRS += fs/fat LIB_SUBDIRS += fs/jffs2 LITEOS_SUBDIRS = $(LIB_SUBDIRS) $(HIDE)for dir in $(LITEOS_SUBDIRS); \ do $(MAKE) -C $$dir all || exit 1; \ done
链接及各类处理
$(LD) $(LITEOS_LDFLAGS) $(LITEOS_TABLES_LDFLAGS) $(LITEOS_DYNLDFLAGS) -Map=$(OUT)/$@.map -o $(OUT)/$@ --start-group $(LITEOS_LIBDEP) --end-group # $(SIZE) -t --common $(OUT)/lib/*.a >$(OUT)/$@.objsize $(OBJCOPY) -O binary $(OUT)/$@ $(LITEOS_TARGET_DIR)/$@.bin $(OBJDUMP) -t $(OUT)/$@ |sort >$(OUT)/$@.sym.sorted $(OBJDUMP) -d $(OUT)/$@ >$(OUT)/$@.asm # $(NM) -S --size-sort $(OUT)/$@ >$(OUT)/$@.size
1.4 核心总结
1.4.1 生成内核的过程
配置内核时，配置信息放在.config里，比如：LOSCFG_FS_FAT=y
kernel/liteos_a/Makefile会包含很多文件，比如kernel/liteos_a/tools/build/mk/los_config.mk
它会看到LIB_SUBDIRS和LITEOS_BASELIB这两个变量
LIB_SUBDIRS表示要进入那个子目录编译
LITEOS_BASELIB表示要把哪些库链接进内核
比如：
```shell ifeq ($(LOSCFG_FS_FAT), y) LITEOS_BASELIB += -lfat LIB_SUBDIRS += fs/fat LITEOS_FAT_INCLUDE += -I $(LITEOSTHIRDPARTY)/FatFs/source endif ```
编译子目录：进入LIB_SUBDIRS指定的子目录，执行make all
对于子目录xxx的编译，一般是生成libxxx.a
链接内核 * 把 LITEOS_BASELIB指定的库都链接进内核
1.4.2 增加模块
在kernel/liteos_a/Makefile能包含的文件中，增加这2个变量：
LIB_SUBDIRS += 源码目录/xxx
LITEOS_BASELIB += -lxxx
在源码目录/xxx下仿照fs/fat/Makefile增加Makefile
