    Makefile  编写

     

    Make  -f  makefile1 指定

    如下是 本人的一点makefile学习笔记，再分享一个不错的写makefile总结的网址：

    http://www.cnblogs.com/wang_yb/p/3990952.html

    Makefile  $@, $^, $< 
    $@  表示目标文件
    $^  表示所有的依赖文件
    $<  表示第一个依赖文件
    $?  表示比目标还要新的依赖文件列表
    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

    方法十、

    obj-m := driver.o
    MAKEOPT :=
    ARCH="arm"
    CROSS_COMPILE="arm-none-linux-gnueabi-"

    ARM_LINUX_KERNEL := "/home/zhangbh/firmware/build_dir/linux-brcm5830_sxxx-prolin2/linux-3.6.5/"

    PWD = $(shell pwd)

    all:
    $(MAKE) $(MAKEOPT) -C $(ARM_LINUX_KERNEL) M=$(PWD) modules

    clean:
    rm -rf .*.cmd *.o *.mod.c *.ko .tmp_versions Module.symvers .Makefile.swp modules.order

    方法十一、

    L_DIR=-L /home/zhangbh/new/firmware/staging_dir/target-arm-none-linux-gnueabi/usr/lib
    I_DIR=-I /home/zhangbh/new/firmware/staging_dir/target-arm-none-linux-gnueabi/usr/include/

    L_FLAG=-losal
    -lcbinder
    -ljpeg
    -lfreetype
    -lpng
    -lz
    -lpthread
    -lrt
    -lcrypt
    -lssl
    -lcrypto
    -lts
    -lprop
    -lcutils
    -lxui

    VBS_t:VBS.c
    arm-none-linux-gnueabi-gcc -o $@ $< $(I_DIR) $(L_DIR) $(L_FLAG)

    方法十三、

    obj-m:=demo.o

    ARCH:=arm
    CROSS_COMPILE:=/home/zhangbh/cygnus/3.5.4-RC2/iproc/buildroot/buildroot/host/usr/bin/
    KERNEL_HEADERS:=/home/zhangbh/cygnus/3.5.4-RC2/iproc/kernel/linux-3.6.5

    build:kernel_modules
    kernel_modules:
    make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNEL_HEADERS) M=$(CURDIR) modules

    clean:
    make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNEL_HEADERS) M=$(CURDIR) clean

    方式十四、 驱动和应用反汇编调试 objdump

    obj-m := kmod-demo1.o
    MAKEOPT := ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
    #CFLAGS := -O2 -DMODULE -D__KERNEL__ ${WARN} ${INCLUDE}
    ARM_LINUX_KERNEL := /home/zhangbh/Prolin_os/si/Prolin/firmware_cygnus/build_dir/linux-brcm5830_sxxx-prolin2/linux-3.6.5
    ccflags-y :=-g
    PWD = $(shell pwd)

    all:
    $(MAKE) $(MAKEOPT) -C $(ARM_LINUX_KERNEL) M=$(PWD) modules

    .PHONY: clean

    clean:
    rm -rf .*.cmd *.o *.mod.c *.ko .tmp_versions Module.symvers .Makefile.swp modules.order

     

    info 可以用来在makefile中打印

include $(TOPDIR)/.config 
$(info tttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt)
$(info $(CONFIG_ENABLE_AA))


include $(TOPDIR)/.config 
ifeq ($(CONFIG_ENABLE_PCI),y)
EXTRA_CFLAGS += -DCONFIG_ENABLE_PCI
endif
 

 ifeq ($(CONFIG_ENABLE_PCI),y)

EXTRA_CPPFLAGS += -DCONFIG_ENABLE_PCI
endif

 编译的时候可以在error时停下

34 #ifdef CONFIG_ENABLE_PCI
35 #error "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
36 printk("

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa===============

");
37 #endif
