XST issue / Answer record does not help

I'm facing an issue using TextIO in initialising a ROM block in my design...

Here's the code snippet with the issue ::

architecture Behavioral of roms2 is type rom_mem_type is array (0 to 31) of std_logic_vector (15 downto

impure function rom_function(temp : in string) return rom_mem_type is variable line_buffer : LINE ; variable count: integer := 0; variable word: bit_vector(1 to 16); variable rom_word_buffer : std_logic_vector(15 downto 0); variable rom_buffer : rom_mem_type;

begin for I in rom_mem_type'range loop

readline (rom_file_ptr, line_buffer);

exit when endfile (rom_file_ptr); read (line_buffer, word);

-- exit when endfile (rom_file_ptr); rom_buffer(I) := to_stdlogicvector(word); end loop; return rom_buffer;

end function;

signal rom_mem : rom_mem_type := rom_function("") ;
