Link error "undefined reference to `__gxx_personality_v0'" and g++

Undefined Symbol ___gxx_personality_v0 on link

I have a problem with the following program.

// fkt.cpp

#include "fkt.h"

int add2(int a, int b)
{
    return a+b;
}

And the header:

// fkt.h

int add2(int a, int b);

Now I compile this with:

g++ -c fkt.cpp

Now I run nm and get:

00000000 T _Z6add2ii
         U __gxx_personality_v0

When I want to use the function anywhere I get:

(.eh_frame+0x12): undefined reference to `__gxx_personality_v0'

How can I solve this problem? (I'm using Ubuntu Linux.)
