手把手教你写makefile【原创】
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：

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("\r\n\r\naaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa===============\r\n\r\n"); 37 #endif
