Force virtual destructors? C++

Viewed 2221

I didn't see the answer to this in the C++ Faq lite:

How do I define a base class so every class inheriting it is required to define a destructor?

I tried running this program

struct VDtor { virtual ~VDtor()=0;  };
struct Test:VDtor { virtual ~Test(){}  };
int main() { delete new Test; return 0; }

http://codepad.org/wFcE71w3 With the error

In function `Test::~Test()':
t.cpp:(.gnu.linkonce.t._ZN4TestD0Ev+0x1e): undefined reference to `VDtor::~VDtor()'
In function `Test::~Test()':
t.cpp:(.gnu.linkonce.t._ZN4TestD1Ev+0x1e): undefined reference to `VDtor::~VDtor()'

So, is it possible?
