[SOLVED] ERROR: HDLParsers:3312

Here's the top-level architecture I'm trying to synthesize.

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;

entity traitement_top is
Port ( mclk : in STD_LOGIC;
btn : in STD_LOGIC_VECTOR (3 downto 0);
sw : in STD_LOGIC_VECTOR (7 downto 0);
hsync : out STD_LOGIC;
vsync : out STD_LOGIC;
red : out STD_LOGIC_VECTOR (2 downto 0);
green : out STD_LOGIC_VECTOR (2 downto 0);
blue : out STD_LOGIC_VECTOR (1 downto 0));
end traitement_top;

architecture arch_traitement_top of traitement_top is

signal clr, clk25, vidon: std_logic;
signal hc, vc: std_logic_vector(9 downto 0);
signal M: std_logic_vector(7 downto 0);
signal rom_addr16: std_logic_vector(15 downto 0);


begin

clr <= btn(3);
U1 : clkdiv port map(mclk => mclk, clr => clr, clk => clk25);

U2 : vga_640x480 port map(clk => clk25, clr => clr, hsync => hsync,
vsync => vsync, hc => hc, vc => vc, vidon => vidon);

U3 : vga_bsprite port map(vidon => vidon, hc => hc, vc => vc, M => M,
sw => sw,
rom_addr16 => rom_addr16, red => red, green => green, blue => blue);

U4 : memory port map (addr => rom_addr16, clk => clk25, dout => M);


end arch_traitement_top;

When I synthesize a VHDL design, the VHDL parser reports one of the following errors:

ERROR:HDLParsers:3312 - "C:/Users/FEMI/Documents/Projects/traitement d'image/Projet_Final/traitement_top.vhd" Line 54. Undefined symbol 'clkdiv'.

Thanks for your help.

When instantiating a component you need to either:
1. Use direct instantiation
2. Add a component declaration.

You have done neither.

Oh my... Jeez. How could I have missed that.
I'll fix that and get back to you. Thanks!

Everything went fine... Thanks again.
