Fixed point ieee_2008 compilation errors in xilinx vivado 20

Hello,
I added the fixed_float_types.vhd, fixed_generic_pkg.vhd, fixed_generic_pkg-body.vhd, fixed_pkg.vhd to my project,
I set the library for them to ieee.
I wrote the following code


library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.fixed_float_types.all;
use IEEE.fixed_pkg.all;

entity test_mul is
-- Port ( );
end test_mul;

architecture Behavioral of test_mul is
signal a,b :sfixed(7 downto -6);
signal c:sfixed(8 downto -6);
begin
c<=a +b;

end Behavioral;

I got the following warnings and errors :
