Problems using member function as custom deleter with std::shared_ptr

by 
std::shared_ptr<SDL_Surface>(SDL_LoadBMP(....), [=](SDL_Surface* surface)
{
    std::cout << "Deleting surface\n";
    SDL_FreeSurface(surface);
});

or

void DeleteSurface(SDL_Surface* surface)
{
    std::cout << "Deleting surface\n";
    SDL_FreeSurface(surface);
}

std::shared_ptr<SDL_Surface>(SDL_LoadBMP(....), DeleteSurface);

EDIT:

Seeing your updated question, DeleteSurface should be a non-member function, otherwise you need to use std::bind or std::mem_fn or some other member function pointer adapter.
