我有5个源文件(main.c,memory.c等),我想为所有这些文件生成依赖文件。
当我在线搜索时,我发现大多数人只遭受由编译器创建的那些文件的困扰,有些人通过将其强行添加到目录中来解决此问题。但是,我想有意地将它们创建为(main.dep,memory.dep等)
我如何让make通过我的命令为我自动创建它们:
$ make build
我想这将是我要放入CPPFLAGS的某种顺序,然后将CPPFLAGS包含到我的$(TARGET).out配方中,但是我不知道到底是什么。有什么想法吗?
这是我的Makefile:
include sources.mk
# Platform Overrides
ifeq ($(PLATFORM),MSP432)
# Architectures Specific Flags
LINKER_FILE = msp432p401r.lds
CPU = cortex-m4
ARCH = thumb
SPECS = nosys.specs
COMPILE = -DMSP432
LDFLAGS_ARCH = -T $(LINKER_FILE)
CFLAGS_ARCH = -mcpu=$(CPU) -m$(ARCH) --specs=$(SPECS) -march=armv7e-m
-mfloat-abi=hard -mfpu=fpv4-sp-d16
OBJS = $(SOURCES:.c=.o)
DUMP = arm-none-eabi-objdump
# Compiler Flags and Defines
CC = arm-none-eabi-gcc
LD = arm-none-eabi-ld
endif
ifeq ($(PLATFORM),HOST)
OBJS = $(SOURCES_BOTH:.c=.o)
COMPILE = -DHOST
CC = gcc
DUMP = objdump
endif
TARGET = c1m2
LDFLAGS = -Wl,-Map=$(TARGET).map $(LDFLAGS_ARCH)
CFLAGS = $(CFLAGS_ARCH) $(INCLUDES) -Wall -Werror -g -O0 -std=c99
$(COMPILE)
CPPFLAGS =
.PHONY: build
build: $(TARGET).out
.PHONY: compile-all
compile-all: $(OBJS)
CLEANO = main.o memory.o interrupts_msp432p401r_gcc.o
startup_msp432p401r_gcc.o system_msp432p401r.o
CLEANI = main.i memory.i interrupts_msp432p401r_gcc.i
startup_msp432p401r_gcc.i system_msp432p401r.i
CLEANASM = main.asm memory.asm interrupts_msp432p401r_gcc.asm
startup_msp432p401r_gcc.asm system_msp432p401r.asm
.PHONY: clean
clean:
$(RM) $(TARGET).out $(TARGET).map $(CLEANO) $(CLEANI) $(CLEANASM)
%.o : %.c
$(CC) -c $< $(CFLAGS) -o $@
%.i : %.c
$(CC) -E $< $(CFLAGS) -o $@
%.asm : %.o
$(DUMP) -S --disassemble $< > $@
$(TARGET).out: $(OBJS)
$(CC) $(OBJS) $(CFLAGS) $(LDFLAGS) -o $@
答案 0 :(得分:1)
您只需在编译步骤中添加一行即可:
%.o : %.c
$(CC) -c $< $(CFLAGS) -o $@
将成为:
%.o : %.c
# dep generation
$(CC) -MM $< > $<.dep
# compilation
$(CC) -c $< $(CFLAGS) -o $@
如果您希望依赖性文件扩展名是.dep
而不是.c.dep
,则可以调整以下规则:
%.o : %.c
# dep generation
$(CC) -MM $< > $(patsubst %.c,%.dep,%<)
# compilation
$(CC) -c $< $(CFLAGS) -o $@
