Linux下如何编译这个程序?

[pressman]

}

int Tdate::IsLeapYear()
{
return((year%4==0&&year%100!=0)||(year%400==0));

void Tdate::Print()

cout<<year<<"-"<<month<<"-"<<day<<endl;

}

int main(void)

Tdate s;
s.Set(2,15,1998);

return 0;
}

#(OS DEBIAN 2.4.20)
上面三个文件放在同一目录下,我用g++ test.cpp -o test编译,出错(当然会错了!)
ERROR CODE:
root@kod:/# g++ ch11_2.cpp -o ch11_2
/tmp/ccbLPF1c.o: In function `SomeFunc(Tdate *)':
/tmp/ccbLPF1c.o(.text+0xe): undefined reference to `Tdate::Print(void)'

/tmp/ccbLPF1c.o: In function `main':
/tmp/ccbLPF1c.o(.text+0x6c): undefined reference to `Tdate::Set(int, int, int)'
collect2: ld returned 1 exit status

不知道要输入什么样的命令才行,是不是要用MAKEFILE?

Tdate都没编译这么link的上呢!

[winux0]

g++ -o test test.cpp Tdate.cpp

[xmzh]

up!

[xmzh]

up

[jacksg]

g++ -c Tdate.cpp -o libTdate.o
ar rcs libTdate.a libTdate.o
cp libTdate.a /lib
g++ test.cpp -o test -lTdate
这应该是你想要的结果吧。

把头文件里面的#include <iostream.h>改成:
#include <iostream>
using namespace std;

然后先编译TDate.cpp: g++ -c TDate.cpp生成TDate.o
再编译test.cpp: g++ -c test.cpp生成test.o
最后连接:g++ -o test test.o TDate.o生成test可执行文件.

[starstargao]

g++ -o test test.cpp Tdate.cpp

[pressman]

还是不行,不过还是结帖吧,谁要我说了呢!

[gettext]

# g++ Test.cpp Tdate.cpp

# g++ ch11_2.cpp -o ch11_2 Tdate.cpp

[blankman]

g++ test.cpp Tdate.cpp -o test

如果要分别检查的话
g++ -c Tdate.cpp
g++ -c test.cpp
这样只编译不连接

[pressman]

再请问:
上面的代码如下编译出现了这样的错误信息!
重复定义?

root@kod:~/# g++ test.cpp -o test Tdate.cpp

/tmp/ccUFZ6F1.o: In function `main':
/tmp/ccUFZ6F1.o(.text+0x144): multiple definition of `main'

请各位帮帮忙,下午下班时结帖!
