(1)创建目录结构

(2)输入"tree"命令，查看目录；若没有则安装tree命令 (sudo apt-get install tree )

[html] view plain copy print ?

1. //f1.c  
2.   
3. #include "../include/myinclude.h"                                                                              
4. void print1()  
5. {  
6.     printf("Message f1.c\n");  
7.     return;  
8. }  

[html] view plain copy print ?

1. //Makefile (/f1目录下的)  
2.   
3. ../$(OBJS_DIR)/f1.o:f1.c                                                                                       
4.     $(CC) -c $^ -o $@  

f2.c 和f2目录下的Makefle和f1目录下的除名字外内容相同

[html] view plain copy print ?

1. //main.c   
2.   
3. #include <stdio.h>                                                                                             
4. int main()  
5. {  
6.     print1();  
7.     print2();  
8.   
9.     return 0;  
10. }  

[html] view plain copy print ?

1. //Makefile (/man目录下的Makefile)  
2.   
3. ../$(OBJS_DIR)/main.o:main.c                                                                                   
4.     $(CC) -c $^ -o $@  

[html] view plain copy print ?

1. //顶层目录下的Makeflie文件  
2. cc=gcc                                                                                                         
3. SUBDIRS=f1 \  
4.         f2 \  
5.         main \  
6.         obj  
7. OBJS=f1.o f2.o main.o  
8. BIN=myapp  
9. OBJS_DIR=obj  
10. BIN_DIR=bin  
11. export CC OBJS BIN OBJS_DIR BIN_DIR  
12.   
13. all:CHECK_DIR $(SUBDIRS)  
14. CHECK_DIR:  
15.     mkdir -p $(BIN_DIR)  
16. $(SUBDIRS):ECHO  
17.     make -C $@  
18. ECHO:  
19.     @echo $(SUBDIRS)  
20.     @echo begin compile  
21. CLEAN:  
22.     @$(RM) $(OBJS_DIR)/*.o  
23.     @rm -rf $(BIN_DIR)  

[html] view plain copy print ?

1. //Obj目录下的Makefile  
2.   
3. ../$(BIN_DIR)/$(BIN):$(OBJS)                                                                                   
4.     $(CC) -o $@ $^  

[html] view plain copy print ?

1. include目录下的myinclude.h 文件  
2. #include <stdio.h>
