#include <gtkmm.h>

class examp : public Gtk::Window {

public:

     examp();
    ~examp() { }

private:

    Gtk::Adjustment m_adj;
    Gtk::HScale     m_hscale;

    m_hscale.set_value_pos(Gtk::POS_TOP);
    m_hscale.set_draw_value();
    m_hscale.set_size_request(200, 30);

    add(m_hscale);
    show_all_children();

int main(int argc, char** argv)

I suggest you to turn on warnings on g++ with -Wall and -Wextra
