代码路径：
代码：
main.cpp
#include<iostream>
using namespace std;
#include "zte.h"
#include "h3c.h"
int main()
{
zte();
h3c();
return 0;
}
zte.cpp
#include<iostream>
using namespace std;
void zte()
{
cout << "hello zte .." << endl;
return;
}
zte.h
#ifndef _ZTE_H_
#define _ZTE_H_
void zte();
#endif
h3c.cpp
#include<iostream>
using namespace std;
void h3c()
{
cout << "hello h3c .." << endl;
return;
}
h3c.h
#ifndef _H3C_H_
#define _H3C_H_
void h3c();
#endif
makefile
基础版：
{
main:main.o zte.o h3c.o
g++ -o main main.o zte.o h3c.o
main.o:main.cpp zte.h h3c.h
g++ -c main.cpp -o main.o
zte.o:zte.cpp
g++ -c zte.cpp -o zte.o
h3c.o:h3c.cpp
g++ -c h3c.cpp -o h3c.o
clean:
rm -rf *.o *.out *.s main
hello:
g++ -o main main.o zte.o h3c.o
./main
}
注：1，g++ -c *.cpp 默认生成对应的.o文件，所以-o *.o可以不写
2，g++或者gcc前面一定要有tab
优化版：变量使用：
{
OBJS = main.o zte.o h3c.o
INC = zte.h h3c.h
TARGET = main
main:$(OBJS)
g++ -o $(TARGET) $(OBJS)
main.o:main.cpp $(INC)
g++ -c main.cpp -o main.o
zte.o:zte.cpp
g++ -c zte.cpp -o zte.o
h3c.o:h3c.cpp
g++ -c h3c.cpp -o h3c.o
clean:
rm -f *.o *.out *.s main
hello:
g++ -o $(TARGET) $(OBJS)
./$(TARGET)
}
精简版：make自动推导依赖文件
{
OBJS = main.o zte.o h3c.o
INC = zte.h h3c.h
TARGET = main
main:$(OBJS)
g++ -o $(TARGET) $(OBJS)
main.o:$(INC)
zte.o:
h3c.o:
clean:
rm -f *.o *.out *.s main
hello:
g++ -o $(TARGET) $(OBJS)
./$(TARGET)
}
执行结果：
[huchangkun@vm64-1 hello]$ make -j
g++ -c -o main.o main.cpp
g++ -c -o zte.o zte.cpp
g++ -c -o h3c.o h3c.cpp
g++ -o main main.o zte.o h3c.o
[huchangkun@vm64-1 hello]$ make hello
g++ -o main main.o zte.o h3c.o
./main
hello zte ..
hello h3c ..
[huchangkun@vm64-1 hello]$
[huchangkun@vm64-1 hello]$ make clean
rm -f *.o *.out *.s main
[huchangkun@vm64-1 hello]$ ls
h3c.cpp h3c.h main.cpp makefile zte.cpp zte.h
[huchangkun@vm64-1 hello]$
