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

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.)

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: https://stackoverflow.com/questions/329059/what-is-gxx-personality-v0-for

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

It sounds like you're trying to link with your resulting object file with gcc instead of g++:
