如何在Ubuntu Linux下编译C++?

我剪切并粘贴了以下代码 a previous question 进入名为“avishay.cpp”的文件,然后运行

gcc avishay.cpp

只从链接器获取以下错误消息。怎么了,我该怎么办?

carl@carl-ubuntu:~/Projects/StackOverflow$ gcc -static avishay.cpp

C++代码(不是我的代码,我只是想运行它):

#include <iostream>
using namespace std;

class A
{
private:
   int _dmember;

public:
   void func()
   {
     cout<<"Inside A!! "<<endl;
     cout<<_dmember; // crash when reach here.
   }
};

int main ()

{

    A* a= NULL;

    a->func(); // prints "Inside A!!!" 

    return 1;
}
