求助：uvm的回调怎么使用`uvm_do_callbacks

oscillator_cn1

各位：
      正在看《A practical Guide to Adopting the Universal Verification
》，正看到第四章最后的回调，将书上的例子跑一下，结果有错，我是新手，不知道遇到这种类型的错误该怎么弄，特来请教大家。
      systemverilog代码：
program test;
    import uvm_pkg::*;
    `include "uvm_macros.svh"

    class street extends uvm_component;
        `uvm_component_utils(street)
        function new(string name, uvm_component parent);
            super.new(name, parent);
        endfunction : new
        task run();
            `uvm_info("INFOl", "I vacationed here in 2010", UVM_LOW)
        endtask : run
    endclass : street

    class city extends uvm_component;
        street  Main_St;
        `uvm_component_utils(city)
        `uvm_register_cb(city,city_cbs)
        function new(string name, uvm_component parent);
            super.new(name, parent);
        endfunction : new
        function void build();// note that we allocate in the build()
            super.build();
            Main_St = street::type_id::create("Main_St", this);
        endfunction : build
        task run () ;
            uvm_component child, parent;
            string pr, ch;
            child = get_child("Main_St");
            parent= get_parent();
            //pr= parent.get_full_name();
            pr = parent.get_name();
            ch = child.get_name();
            `uvm_do_callbacks(city,city_cbs,pre_info(this))
            `uvm_info(get_type_name(),$psprintf("Parent:%s Child:%s",pr,ch),UVM_LOW);
        endtask :run
    endclass:city

    virtual class city_cbs extends uvm_callback;
        function new(string name="city_cb");
            super.new(name);
        endfunction
        pure virtual function void pre_info(city c);
    endclass : city_cbs

    class state extends uvm_component;
        city Capital_city;
        `uvm_component_utils(state)
        function new(string name, uvm_component parent);
            super.new(name, parent);
        endfunction : new
        function void build();
            super.build();
            Capital_city=city::type_id::create("Capital_city", this);
        endfunction : build
        function void end_of_elaboration();
            this.print();
        endfunction : end_of_elaboration
    endclass:state
   
    class my_city_cb extends city_cbs;
        function new(string name ="my_city_cb");
            super.new(name);
        endfunction
        virtual function void pre_info(city c);
            `uvm_info("my_city_cb",$psprintf("pre_info called for city %s",c.get_full_name()),UVM_LOW)
        endfunction
    endclass:my_city_cb

    state Florida=state::type_id::create("Florida", null);
    state New_York=state::type_id::create("New_York", null);
    typedef uvm_callbacks#(city,city_cbs) city_cb;
    my_city_cb cb = new;
    // Start UVM Phases
    initial begin
        city_cb::add(null,cb);
        run_test();
    end
    initial #100 global_stop_request();
endprogram: test
用irun -uvm test.sv运行得到的错误提示：
file: test.sv
            `uvm_do_callbacks(city,city_cbs,pre_info(this))
                                                                                   |
