ieee float and fixed point packages

Included the ieee.fixed and float as shown below in top.vhdl. The files are in Quartus/ieee/2008 folder.

library ieee;
use ieee.fixed_pkg_vhdl2008.all;
use ieee.float_pkg_vhdl2008.all;

In compilation, the following error and not sure what these means.

Error (10481): VHDL Use Clause error at PDA_361000893_TOP_FPGA.vhd(31): design library "ieee" does not contain primary unit "fixed_pkg_vhdl2008". Verify that the primary unit exists in the library and has been successfully compiled.
Error (10800): VHDL error at PDA_361000893_TOP_FPGA.vhd(31): selected name in use clause is not an expanded name
Error (10481): VHDL Use Clause error at PDA_361000893_TOP_FPGA.vhd(32): design library "ieee" does not contain primary unit "float_pkg_vhdl2008". Verify that the primary unit exists in the library and has been successfully compiled.

      I tried that and got an error. So removed that and added straight in VHDL file the following and worked.

      library ieee_proposed;
      use ieee_proposed.fixed_float_types.all;
      use ieee_proposed.fixed_pkg.all;

      The error is about the library not compiled. But don't know how to compile the ieee library. Thanks anyway.
