这个程序如何写makefile？
main.c:

C/C++ code

#include "def1.h"extern void function2();extern void function3();int main(){    function2();    function3();    //exit(EXIT_SUCCESS);}

f1.c:

C/C++ code

#include "def2.h"#include "def3.h"void function3() {printf("aaabbbccc");}

f2.c:

C/C++ code

#include "def2.h"#include "def3.h"void function3() {}

f3.c:

C/C++ code

#include "def1.h"#include "def2.h"void function2(){}

[解决办法]
main:main.c f1.c f2.c f3.c
cc -o main main.c f1.c f2.c f3.c
clean:
@rm -rf main
[解决办法]

探讨

main:main.c f1.c f2.c f3.c
cc -o main main.c f1.c f2.c f3.c
clean:
@rm -rf main

[解决办法]
main:main.c f1.c f2.c f3.c
cc -o main main.c f1.c f2.c f3.c
clean:
@rm -rf main

这样就可以
[解决办法]
main:main.c f1.c f2.c f3.c def1.h def2.h def3.h
cc -o main main.c f1.c f2.c f3.c
clean:
@rm -rf main

这样更好
