Re: [Boost-users] Fwd: bind, template member function and thread

Why do you need a function instance at all?

Just use boost::bind and that's it...

    Profile p;
    boost::shared_ptr< TTImage<unsigned char> > image(new TTImage<unsigned
char>);

    boost::thread t(
        boost::bind
            (
                &Profile::template ComputeRadiometries<unsigned char>
            ,    p
            ,    image
            ,    BICUBIC
            )
        );

This code compiles fine for me.
