Intro to Makefile

Abstract
This blog would show you what to write a "makefile" file.

1. Concept
A makefile is a file containing a set of directives, directing a complier to link a program in a certain order.

2. An Example
File1.h

#ifndef file1_h#define file1_hvoid tool1(char *);void tool1(constchar *);#endif

File1.cpp

#include <stdio.h>#include "file1.h"void tool1(char *str){    printf("This is file1 print: %s\n",str);}voidchar *str){    printf("This is file1 print: %s\n",str);}

File2.h

#ifndef file2_h#define file2_hvoid tool2(char *);void tool2(constchar *);#endif

File2.cpp

#include <stdio.h>#include "file2.h"void tool2(char *str){    printf("This is file2 print: %s\n",str);}voidchar *str){    printf("This is file2 print: %s\n",str);}

Main.cpp

#include <stdio.h>#include <stdlib.h>#include "file1.h"#include "file2.h"int main(){    char"hello";    tool1(str1);    constchar"hello";    tool1(str1_c);    char"hello";    tool2(str2);    constchar"hello";        tool2(str2_c);}

Makefile
