question about VHDL library

Hi all,

when I compile my VHDL design, there is always a error saying that * design library "book_lib" does not contain primary unit "utils_pkg"*.

Does anyone know how to fix it?Thanks

Following is my code:

library ieee,book_lib;

use ieee.std_logic_1164.all,book_lib.utils_pkg.all;

--bla bla bla

    You need to find the file that contains package utils_pkg, and add it to your project, in the book_lib library.

    library uses are usually ended with a semi-colon (;).

    Not necessary: you can write a comma separated list of things to use. 

    use ieee.NUMERIC_BIT.all, ieee.std_logic_1164.all;

    is the same as: 

    use ieee.NUMERIC_BIT.all;
use ieee.std_logic_1164.all;

    But this error means you have not compiled the utils package into the book_lib library.

    I am not familiar with VHDL, but is it supposed be a comma after "all" ?
