Sorry, Let's see at a complete example:

I define a *great* class: A.
A::A()
{
    cout << "A::A()" << endl ;
}

>g++ -c -g -fpic A.cpp
>g++ -g -shared -o A.so A.o   (2)

An *amazing* main.
int main ()
{ A  a ;}

>g++ -c -g -fpic main.cpp
>g++ -g -o main main.o A.so (4)

I set LD_LIBRARY_PATH, to use the current dir.
And... all works fine !

>./main
A

Althrough the things are alrights, maybe I've miss some compiler options !

Should I add the -fpic flag at the (2) & (4) compilation lines ?
It works whether I set it or not.
