这是makefile代码，我使用“ make”执行它。

CC=arm-none-eabi-gcc
CXX = arm-none-eabi-g++
BUILD_PATH = ../../build
dir_guard=mkdir -p $(@D)
STATIC_OPENTHREAD_LIB = $(BUILD_PATH)/third_party/libopenthread.a
AR = arm-none-eabi-gcc-ar -cr 

TARGET_OPENTHREAD_SRC_PATH = openthread


NRF_802154_MODULE_NAME = nrf_802154
NRF_802154_MODULE_PATH ?= $(PROJECT_ROOT)/third_party/$(NRF_802154_MODULE_NAME)

TARGET_NRF_802154_PATH = $(NRF_802154_MODULE_PATH)

ALLOBJ := $(addprefix $(BUILD_PATH)/, $(CSRC:.c=.o))

all:$(ALLOBJ)

%.o: %.c
    echo $^

clean:
    rm -rf $(BUILD_PATH)

但是失败，并显示以下错误消息：

make: *** No rule to make target '../../build/openthread/third_party/NordicSemiconductor/drivers/radio/nrf_802154_notification_swi.o', needed by 'all'.  Stop

似乎无法识别模式。

％模式必须识别正在调用的规则，但不能正常工作

我想做的是我的源代码在另一个目录中，我想构建一个可以编译C并在另一个目录中创建对象的makefile，然后要使用AR创建.a库。

您的模式规则无法匹配，因为您要在两侧匹配整个路径名。但是您的路径前缀不一样，例如

  • 源文件$(TARGET_OPENTHREAD_SRC_PATH)/third_party/...
  • 目标文件../../build/$(TARGET_OPENTHREAD_SRC_PATH)/third_party/...

简单的解决方法是：

ALLOBJ := $(addprefix $(BUILD_PATH)/, $(CSRC:.c=.o))

$(ALLOBJ): $(BUILD_PATH)/%.o: %.c
        .... compiler command line goes in here ....

但是更简单的方法是改为使用VPATH，即告诉make在哪里查找源文件并从源文件中完全删除路径：

# location of the source files (you can have multiple source directories too)
VPATH += $(TARGET_OPENTHREAD_SRC_PATH)/third_party/NordicSemiconductor/drivers/radio

CSRC += nrf_802154_notification_swi.c

ALLOBJ := $(addprefix $(BUILD_PATH)/, $(CSRC:.c=.o))

$(ALLOBJ): $(BUILD_PATH)/%.o: %.c
        .... compiler command line goes in here ....
