Makefile中沒有運行臂無 - EABI-AR沒有連接所有.o文件

Question

我有下面的Makefile

CC=arm-none-eabi-gcc 
AR=arm-none-eabi-ar 

vpath %.c src src/peripherals 
vpath %.o out 

CFLAGS = -g -O2 -Wall -DUSE_STDPERIPH_DRIVER 
CFLAGS += -mlittle-endian -mthumb -mcpu=cortex-m4 -mthumb-interwork 
CFLAGS += -mfloat-abi=hard -mfpu=fpv4-sp-d16 
CFLAGS += -ffreestanding -nostdlib 
CFLAGS += -Iinc -Iinc/cmsis -Iinc/peripherals -Iinc/stm32f4xx 

OUT_DIR=out 

SRCS = misc.c stm32f4xx_adc.c stm32f4xx_can.c stm32f4xx_crc.c stm32f4xx_cryp.c stm32f4xx_cryp_aes.c \ 
    stm32f4xx_cryp_des.c stm32f4xx_cryp_tdes.c stm32f4xx_dac.c stm32f4xx_dbgmcu.c stm32f4xx_dcmi.c stm32f4xx_dma.c \ 
    stm32f4xx_exti.c stm32f4xx_flash.c stm32f4xx_fsmc.c stm32f4xx_gpio.c stm32f4xx_hash.c stm32f4xx_hash_md5.c \ 
    stm32f4xx_hash_sha1.c stm32f4xx_i2c.c stm32f4xx_iwdg.c stm32f4xx_pwr.c stm32f4xx_rcc.c stm32f4xx_rng.c \ 
    stm32f4xx_rtc.c stm32f4xx_sdio.c stm32f4xx_spi.c stm32f4xx_syscfg.c stm32f4xx_tim.c stm32f4xx_usart.c \ 
    stm32f4xx_wwdg.c 

OBJS = $(SRCS:.c=.o) 

.PHONY: libstm32f4.a 

all: libstm32f4.a 

%.o : %.c 
    mkdir -p $(OUT_DIR) 
    $(CC) $(CFLAGS) -c -o $(OUT_DIR)/$@ $^ 

libstm32f4.a: $(OBJS) 
    $(AR) -r $(OUT_DIR)/$@ $(OUT_DIR)/$(OBJS) 

clean: 
    rm -rf $(OUT_DIR) 

但運行make，我的.o文件正在修建好的時候，但關鍵在那裏，無所事事的人打來電話，我正在弄得一團糟。

線

$(AR) -r $(OUT_DIR)/$@ $(OUT_DIR)/$(OBJS) 

可能是我要去哪裏錯了，它的輸出是：

arm-none-eabi-ar -r out/libstm32f4.a out/misc.o stm32f4xx_adc.o stm32f4xx_can.o stm32f4xx_crc.o stm32f4xx_cryp.o stm32f4xx_cryp_aes.o stm32f4xx_cryp_des.o stm32f4xx_cryp_tdes.o stm32f4xx_dac.o stm32f4xx_dbgmcu.o stm32f4xx_dcmi.o stm32f4xx_dma.o stm32f4xx_exti.o stm32f4xx_flash.o stm32f4xx_fsmc.o stm32f4xx_gpio.o stm32f4xx_hash.o stm32f4xx_hash_md5.o stm32f4xx_hash_sha1.o stm32f4xx_i2c.o stm32f4xx_iwdg.o stm32f4xx_pwr.o stm32f4xx_rcc.o stm32f4xx_rng.o stm32f4xx_rtc.o stm32f4xx_sdio.o stm32f4xx_spi.o stm32f4xx_syscfg.o stm32f4xx_tim.o stm32f4xx_usart.o stm32f4xx_wwdg.o 
arm-none-eabi-ar: creating out/libstm32f4.a 
arm-none-eabi-ar: stm32f4xx_adc.o: No such file or directory 
make: *** [libstm32f4.a] Error 1 

時候，在這個看，出/ libstm32f4.a是正確的，但第二句話所有的* .o文件是完全錯誤的，只有out/misc.o被前綴out /文件夾，而不是其餘，導致錯誤？

如何修復我的Makefile以使其在./out/中查找.o文件？我正在使用

vpath %.o out 

不正確，或者是我的arm-none-eabi-ar指令在Makefile中不正確？

Answer 1

簡單地改變

$(AR) -r $(OUT_DIR)/$@ $(OUT_DIR)/$(OBJS) 

到

$(AR) -r $(OUT_DIR)/$@ $(OUT_DIR)/*.o 

DUH！
