Error:HDLCompiler:104: Cannot find float_alg_pkg in library ieee_proposed

Question

When I synthesize the VHDL code from Vivado HLS in Xilinx ISE, some errors appeared.
All the errors are caused by the ' aesl_fp_wrapper.vhd ' file and the first one is described like below:
ERROR:HDLCompiler:104:HDLCompiler:104 - "/home/xq32/code/rvc-cal/shared-cal-programs/meanShift/HLSBackend0801/HLSBackend/TopVHDL/aesl_fp_wrapper.vhd" Line 681: Cannot find <float_alg_pkg> in library <ieee_proposed>. Please ensure that the library was compiled, and that a library and a use clause are present in the VHDL file.
The code is like:
Library IEEE;
use IEEE.std_logic_1164.all;
Library work;
use work.all;
Library ieee_proposed;
use ieee_proposed.float_pkg.all;
use ieee_proposed.float_alg_pkg.all; (ERROR HAPPENED HERE)
entity AESL_WP_FLog is
  generic (
    NUM_STAGE : INTEGER := 13;
    din0_WIDTH : INTEGER := 32;
    din1_WIDTH : INTEGER := 32;
    dout_WIDTH : INTEGER := 32);
  port  (
    clk, reset, ce : std_logic;
    din0 : in std_logic_vector(din0_WIDTH-1 downto 0);
    din1 : in std_logic_vector(din1_WIDTH-1 downto 0);
    dout : out std_logic_vector(dout_WIDTH-1 downto 0));
end AESL_WP_FLog;
More information:
The Vivado HLS generate a folder: ieee_FP_pkg
The following files and folder are inside it:
aesl_fp_wrapper.vhd     fixed_pkg_c.vhd  fuse.xmsgs
fixed_float_types_c.vhd  float_pkg_c.vhd  isim
Within the isim folder: isim>work>fixed_float_types.vdb
Does anyone have idea?
Many thanks

You should add a library which means <float_alg_pkg> .add to library
