makefile实例（2）-多个文件实例

1，源文件依赖关系

                defs.h        command.h        buffer.h
main.cpp        *
util.cpp        *
kde.cpp            *            *
command.cpp        *            *
display.cpp        *                            *
insert.cpp        *                            *
search.cpp        *                            *
files.cpp        *            *                *

2, 源文件

因为这里只是想做一下简单测试，所以很多源文件的内容都是空的。

[[email protected] 1-makefile]#head *.h
==> buffer.h <==
#pragma once
#define BUFFER "BUFFER"

==> command.h <==
#pragma once
#define  COMMAND "COMMAND"

==> defs.h <==
#pragma once
#define DEFS "DEFS"

[[email protected] 1-makefile]#head *.cpp
==> command.cpp <==

==> display.cpp <==

==> files.cpp <==

==> insert.cpp <==

==> kde.cpp <==

==> main.cpp <==
#include <stdio.h>

int main()
{
    printf("Hello World\n");
    return 0;
}

==> search.cpp <==

==> utils.cpp <==

3，makefile 内容（最最原始的）

[[email protected] 1-makefile]#cat makefile
edit :  main.o  kde.o command.o display.o insert.o search.o utils.o files.o
    g++ -o edit main.o kde.o command.o display.o insert.o search.o utils.o files.o

main.o : main.cpp defs.h
    g++ -c main.cpp
kde.o : kde.cpp defs.h command.h
    g++ -c kde.cpp
command.o : command.cpp defs.h command.h
    g++ -c command.cpp
display.o : display.cpp defs.h buffer.h
    g++ -c display.cpp
insert.o : insert.cpp defs.h buffer.h
    g++ -c insert.cpp
search.o : search.cpp defs.h buffer.h
    g++ -c search.cpp
files.o : files.cpp defs.h buffer.h command.h
    g++ -c files.cpp
utils.o : utils.cpp defs.h
    g++ -c utils.cpp
clean :
    rm edit main.o kde.o command.o display.o insert.o search.o files.o utils.o -rf

4，执行make

[[email protected] 1-makefile]#make clean
rm edit main.o kde.o command.o display.o insert.o search.o files.o utils.o -rf

5，运行结果

[[email protected] 1-makefile]#./edit
Hello World

6，执行清理

[[email protected] 1-makefile]#make clean
rm edit main.o kde.o command.o display.o insert.o search.o files.o utils.o -rf
