如何在 Makefile 中使用通配符？

Question

以下片段：

... rest of makefile ...
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usb_bsp.c
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usb_core.c
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usb_dcd.c
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usbd_cdc_core.c 
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usbd_cdc_vcp.c 
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usb_dcd_int.c 
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usbd_core.c 
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usbd_desc.c 
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usbd_ioreq.c 
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usbd_req.c 
SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/usbd_usr.c
... rest of makefile

编译，但如果我将其替换为：

SRCS += $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/$(wildcard *.c)

make命令returns链接器错误：

FingerCell/Source/STM32F4-DISCOVERY_USB/User.o: No such file or directory

STM32F4-DISCOVERY_USB 目录不包含除第一个代码片段中列出的文件之外的其他 .c 文件。 我在这里使用的通配符不正确吗？

Answer 1

SRCS += $(wildcard $(BASEDIR)FingerCell/Source/STM32F4-DISCOVERY_USB/*.c)
