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:

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 # [email protected]是目标%.o %.o:%.c arm-none-linux-gnueabi-gcc -c $< -o [email protected] $(TEST_RES): $(objects) #$(CC) $^ -o [email protected] $(CROSS_COMPILE) $^ -o [email protected] .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 [email protected] .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 [email protected] $(TEST_RES): $(objects) $(CC) $^ -o [email protected] .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 [email protected] $(TEST_RES): $(objects) $(CC) $^ -o [email protected] .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 [email protected] $(OBJDIR)/%.o:./package/%.c $(CC) $(INCLUDDIR) -c $< -o [email protected] $(TEST_RES): $(objects) $(CC) $^ -o [email protected] .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 [email protected] $(OBJDIR)/%.o:./package/%.c $(CC) $(INCLUDDIR) -c $< -o [email protected] $(TEST_RES): $(OBJECTS) $(CC) $^ -o [email protected] .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 [email protected] $(OBJDIR)/%.o:./package/%.c $(CC) $(INCLUDDIR) -c $< -o [email protected] $(TEST_RES): $(OBJECTS) $(CC) $^ -o [email protected] .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 [email protected] $(OBJDIR)/%.o:./package/%.c $(CC) $(INCLUDDIR) -c $< -o [email protected] $(TEST_RES): $(OBJECTS) $(CC) $^ -o [email protected] .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 [email protected] -std=gnu99
$(OBJDIR)/%.o:./package/%.c
$(CC) $(INCLUDDIR) -c $< -o [email protected] -std=gnu99
$(TEST_RES): $(OBJECTS)
$(CC) $^ -o [email protected] -lpthread -std=gnu99
chmod a+x [email protected]
.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
