Weird error in ncvhdl

Hi all,

I got error since I use env.cmd file and setenv commands. Below, this is what the compiler show me:

../RTL/analog_mux2_ent.vhdl:
             S  : in real_vector (2**INPUTS_SEL-1 downto 0);
                               |
ncvhdl_p: *E,IDENTU (../RTL/analog_mux2_ent.vhdl,12|24): identifier (REAL_VECTOR) is not declared [10.3].
        errors: 1, warnings: 0

With real type I've gor no error, but with real_vector I've got this error. Can you help please ?
