makefile的几种写法【原创】

方式一、

同一个目录下有多个.c  .h文件

CROSS_COMPILE=arm-none-linux-gnueabi-gcc

#CC=arm-none-linux-gnueabi-gcc

       

TEST_RES := regDebug

objects = main.o uart.o

 

#下面这行表示依赖关系 表示所有的.o文件都是依赖于.c

#  $@是目标%.o

%.o:%.c

        arm-none-linux-gnueabi-gcc -c $< -o $@

 

$(TEST_RES): $(objects)

        #$(CC) $^ -o $@

        $(CROSS_COMPILE) $^ -o $@

       

.PHONY: clean

 

clean:

        rm -rf .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)

 

方式二、

同一个目录下有多个.c  .h文件

CC=arm-none-linux-gnueabi-gcc

       

TEST_RES := regDebug

objects = main.o uart.o

 

$(TEST_RES): $(objects)

        $(CC) $^ -o $@

       

.PHONY: clean

 

clean:

        rm -rf .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)


方法三、

将编译生成的中间文件放在obj中，编译生成的可执行文件放在bin目录下

TEST_RES := bin/regDebug

objects = ./obj/main.o 
                   ./obj/uart.o
./obj/%.o:%.c

        $(CC) -c $< -o $@

$(TEST_RES): $(objects)

        $(CC) $^ -o $@  

.PHONY: clean

clean:

        rm -rf  .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)

        rm -rf  $(objects)


方法四、

用OBJDIR替换了路径

OBJDIR=obj


TEST_RES := bin/regDebug

objects = $(OBJDIR)/main.o 
                   $(OBJDIR)/uart.o

$(OBJDIR)/%.o:%.c

        $(CC) -c $< -o $@


$(TEST_RES): $(objects)

        $(CC) $^ -o $@
       

.PHONY: clean


clean:

        rm -rf  .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)

        rm -rf  $(objects)


方法五、

将uart.c和uart.h放在package目录下

CC=arm-none-linux-gnueabi-gcc

 

INCLUDDIR=-I package

OBJDIR=obj


TEST_RES := bin/regDebug

objects = $(OBJDIR)/main.o 
                   $(OBJDIR)/uart.o

$(OBJDIR)/%.o:%.c

        $(CC) $(INCLUDDIR) -c $< -o $@

 

$(OBJDIR)/%.o:./package/%.c

        $(CC) $(INCLUDDIR) -c $< -o $@

 

 

$(TEST_RES): $(objects)

        $(CC) $^ -o $@

       

.PHONY: clean

 

clean:

        rm -rf  .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)

        rm -rf  $(objects)

 

方法六、

CC=arm-none-linux-gnueabi-gcc

INCLUDDIR=-I package

OBJDIR=obj

TEST_RES := bin/regDebug

OBJECTS = $(OBJDIR)/main.o

-include ./package/obj.mk

$(OBJDIR)/%.o:%.c

        $(CC) $(INCLUDDIR) -c $< -o $@

$(OBJDIR)/%.o:./package/%.c

        $(CC) $(INCLUDDIR) -c $< -o $@

$(TEST_RES): $(OBJECTS)

        $(CC) $^ -o $@

.PHONY: clean

clean:

        rm -rf  .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)

        rm -rf  $(OBJECTS)

 

 

 

obj.mk

OBJECTS += ./obj/uart.o


方法七、

把所有头文件都放在include目录下

CC=arm-none-linux-gnueabi-gcc

INCLUDDIR=-I include

OBJDIR=obj

TEST_RES := bin/regDebug

OBJECTS = $(OBJDIR)/main.o

-include ./package/obj.mk

$(OBJDIR)/%.o:%.c

        $(CC) $(INCLUDDIR) -c $< -o $@

$(OBJDIR)/%.o:./package/%.c

        $(CC) $(INCLUDDIR) -c $< -o $@

$(TEST_RES): $(OBJECTS)

        $(CC) $^ -o $@

.PHONY: clean

clean:

        rm -rf  .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)

        rm -rf  $(OBJECTS)

方法八、

 

#CC=arm-none-linux-gnueabi-gcc

 

#INCLUDDIR=-I include

#OBJDIR=obj

-include rules.mk

TEST_RES := bin/regDebug


OBJECTS = $(OBJDIR)/main.o
 
-include ./package/obj.mk

$(OBJDIR)/%.o:%.c

        $(CC) $(INCLUDDIR) -c $< -o $@

 

$(OBJDIR)/%.o:./package/%.c

        $(CC) $(INCLUDDIR) -c $< -o $@
 

$(TEST_RES): $(OBJECTS)

        $(CC) $^ -o $@
   

.PHONY: clean


clean:

        rm -rf  .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)

        rm -rf  $(OBJECTS)
 

rules.mk文件中

CC=arm-none-linux-gnueabi-gcc

INCLUDDIR=-I include

OBJDIR=obj

方法九、

目录结构如下

bin下为可执行文件

include 下为头文件

obj 下为编译的中间文件

package下为各种c文件

根目录下makefile

-include rules.mk

TEST_RES := bin/regDebug

OBJECTS = $(OBJDIR)/main.o

-include ./package/obj.mk

$(OBJDIR)/%.o:%.c

        $(CC) $(INCLUDDIR) -c $< -o $@ -std=gnu99

$(OBJDIR)/%.o:./package/%.c

        $(CC) $(INCLUDDIR) -c $< -o $@ -std=gnu99

$(TEST_RES): $(OBJECTS)

        $(CC) $^ -o $@ -lpthread -std=gnu99

        chmod a+x $@

.PHONY: clean

clean:

        rm -rf  .*.cmd *.o *.mod.c  .tmp_versions Module.symvers .Makefile.swp $(TEST_RES)

        rm -rf  $(OBJECTS)

根目录下 rules.mk：

CC=arm-none-linux-gnueabi-gcc

INCLUDDIR=-I include

OBJDIR=obj

package目录下 obj.mk

OBJECTS += ./obj/uart.o \

                    ./obj/Console.o \

                    ./obj/reg_data.o \

                    ./obj/func.o \

                    ./obj/run.o \

                    ./obj/revDataOne.o
