这么长的文件，其实真正用来编译的指令只有几行：
而贯穿整篇Makefile的只有三行代码：
$(BUILD_DIR)/$(TARGET).elf: $(OBJECTS) Makefile
$(CC) $(OBJECTS) $(LDFLAGS) -o $@
$(SZ) $@
正向解析（从Makefile文件->输出结果）
如果要正向解析Makefile文件，需要理清整个文件输出流程，即依赖结构。
其实在这篇makefile里，make就等于make all。
可以看到，make执行的缺省动作就是all这个label，所以当你打下make时，makefile会想办法生成以下三个文件
$(BUILD_DIR)/$(TARGET).elf
$(BUILD_DIR)/$(TARGET).hex
$(BUILD_DIR)/$(TARGET).bin
而我们找到makefile最上面，定义的变量：
可以清楚的看到TARGET、BUILD_DIR这两个变量定义，所以我们所要生成的目标文件实际是：
build/GCC_F103.elf
build/GCC_F103.hex
build/GCC_F103.bin
也就是在目录build下生成这三个文件。而build目录和这三个文件的生成方法也已经给出：
其实把BUILD_DIR和TARGET替换掉，也就是：
build/GCC_F103.elf: $(OBJECTS) Makefile
$(CC) $(OBJECTS) $(LDFLAGS) -o $@
$(SZ) $@
build/%.hex: build/%.elf | build
$(HEX) $< $@
build/%.bin: build/%.elf | build
$(BIN) $< $@
build:
mkdir $@
由此也可以看出来，只要GCC_F103.elf有了，那GCC_F103.hex和GCC_F103.bin都是在GCC_F103.elf基础上生成的，所以肯定要先生成GCC_F103.elf。而build就是一行指令：mkdir build($@代表目标文件，这里目标文件就是build)。接着往下看，GCC_F103.elf这个文件又依赖于 $(OBJECTS)这个变量，也就是需要先生成这个，然后执行下面两行代码。 $(OBJECTS)具体是什么，我们再看上面变量定义：
可以看到这个变量又使用了其他变量，还运用了函数addprefix、notdir和sort。而其中新的两个变量也定义在最上面：
最外层addprefix用法是：
$(addprefix <prefix>, <name-1>, <name-2>...<name-n>)
把前缀prefix加到name前面。
而notdir是把字符串中的路径去掉，比如：
C_SOURCES = F103/Src/main.c
OBJECTS = $(notdir$(C_SOURCES))
最终OBJECT = main.c
还有一个地方$(C_SOURCES:.c=.o)，这里的意思是把C_SOURCES里所有以.c结尾的文件替换为.o结尾的文件。
所以替换展开后OBJECTS其实为：
OBJECTS = \
build/main.o \
build/stm32f1xx_it.o \
build/stm32f1xx_hal_msp.o \
build/stm32f1xx_hal_gpio_ex.o \
build/stm32f1xx_hal_tim.o \
build/stm32f1xx_hal_tim_ex.o \
build/stm32f1xx_hal.o \
build/stm32f1xx_hal_rcc.o \
build/stm32f1xx_hal_rcc_ex.o \
build/stm32f1xx_hal_gpio.o \
build/stm32f1xx_hal_dma.o \
build/stm32f1xx_hal_cortex.o \
build/stm32f1xx_hal_pwr.o \
build/stm32f1xx_hal_flash.o \
build/stm32f1xx_hal_flash_ex.o \
build/system_stm32f1xx.o
接下来看vpath这个关键字，它的用法是
vpath <pattern> <directories>
设置符合pattern的文件的搜索路径是directories
的意思就是，所有.c文件的搜索路径是$(sort $(dir $(C_SOURCES))) ，sort函数用来去掉重复的文件路径，dir函数即取路径和notdir函数刚好相反，最终结果就是所有.c文件的搜索路径是C_SOURCES这个变量去掉文件名只保留路径，去掉重复的并排好序列。
可以看出这两行代码是处理所有.c文件的，而下面的两行代码是处理.s文件的，处理方式都一样，都是把文件后缀换为.o：
注意这里OBJECT是用的 += 而不是 =，代表最后OBJECT里面包含了.c和.s的处理结果。至此我们得到了OBJECT这个变量的最终结果：
OBJECTS = \
build/main.o \
build/stm32f1xx_it.o \
build/stm32f1xx_hal_msp.o \
build/stm32f1xx_hal_gpio_ex.o \
build/stm32f1xx_hal_tim.o \
build/stm32f1xx_hal_tim_ex.o \
build/stm32f1xx_hal.o \
build/stm32f1xx_hal_rcc.o \
build/stm32f1xx_hal_rcc_ex.o \
build/stm32f1xx_hal_gpio.o \
build/stm32f1xx_hal_dma.o \
build/stm32f1xx_hal_cortex.o \
build/stm32f1xx_hal_pwr.o \
build/stm32f1xx_hal_flash.o \
build/stm32f1xx_hal_flash_ex.o \
build/system_stm32f1xx.o
build/startup_stm32f103xe.o
回到我们刚才追溯到OBJECT的地方：
这里已经分析过build/GCC_F103.elf这个文件依赖OBJECT，其实就是生成它依赖那么多.o文件，那这些.o文件从哪里来？
可以看到，所有.o的生成规则Makefile也已经给出。这里的 | $(BUILD_DIR)不作过多解释，其实就是如果要生成.o就要先生成build这个目录，如果生成了build那以后都不需要再生成它了，如果你去掉这个或者只去掉管道符号 |，则每次make都会重新生成所有文件，这里贴出来GUN make的原文描述：
实际这些.o的生成规则其实就是：
$(CC) -c $(CFLAGS) -Wa,-a,-ad,-alms=$(BUILD_DIR)/$(notdir $(<:.c=.lst)) $< -o $@
而里面用到的变量都在上面有定义，因为内容较多不再截图。
所以这一行展开就是：
arm-none-eabi-gcc -c -mcpu=cortex-m3 -mthumb -DUSE_HAL_DRIVER -DSTM32F103xE -IInc -IDrivers/STM32F1xx_HAL_Driver/Inc -IDrivers/STM32F1xx_HAL_Driver/Inc/Legacy -IDrivers/CMSIS/Device/ST/STM32F1xx/Include -IDrivers/CMSIS/Include -IDrivers/CMSIS/Include -Og -Wall -fdata-sections -ffunction-sections -g -gdwarf-2 -MMD -MP -MF"$(@:%.o=%.d)" -Wa,-a,-ad,-alms=$(BUILD_DIR)/$(notdir $(<:.c=.lst)) $< -o $@
可以看到有一部分还未替换的则是根据生成的.o替换为.d和.lst的。其实就是替换变量，具体参数在gcc中的功能需要你自己去查找。(.s生成.o同理，参数并不完全相同)
在生成完所有.o文件后，我们终于可以继续刚才的代码：
同样的替换变量后：
arm-none-eabi-gcc $(OBJECTS) -mcpu=cortex-m3 -mthumb -specs=nano.specs -TSTM32F103ZETx_FLASH.ld -lc -lm -lnosys -Wl,-Map=$(BUILD_DIR)/$(TARGET).map,--cref -Wl,--gc-sections -o $@
arm-none-eabi-size $@
如果变量为空，则实际展开时用空格代替。
最后生成.hex和.bin：
arm-none-eabi-objcopy -O ihex $< $@
arm-none-eabi-objcopy -O binary -S $< $@
$@可以简单理解为targets，而$<则是第一条prerequisites,而$^是所有prerequisites
我们查看输出结果和我们分析的是否一致：
