coupla n00b Q's on libraries

Hi

so have

library  ieee, work;
use  ieee.std_logic_1164.all, work.basic_func.all;

at the start of my code now, with basic_func.vhdl stored in my project directory

but still have same errors. the main one being

Error: VHDL Use Clause error at buzzer.vhd(4): design library "work" does not contain primary unit "basic_func"

then

Error: Ignored construct buzzer at buzzer.vhd(6) because of previous errors -thus-

Error: VHDL error at buzzer.vhd(11): entity "buzzer" is used but not declared

and strangely

Error: VHDL error at buzzer.vhd(14): object "std_logic" is used but not declared

as if even the ieee.std_logic_1164 package is not being used????

once again any help is much appreciated and much thanks for the help so far :)
