VHDL IEEE Library not recognized by RTL Compiler or Genus

Hello,

I guess this is a dumb question but I didn't find any having the same issue as mine or any tutorial to guide me through this process...

I wanted to synthesize a design written in VHDL with either RC or Genus, but I got the same error (and the error repeats for each VHDL file...)

library IEEE;
        |
Error : Missing token. [VHDLPT-672] [read_hdl]
: library clause requires ';', read <identifier> IEEE in file 'addroundkey.vhd' on line 46, column 9.

I guess I need to explicitly point to the IEEE library, which I am not sure how to do. Any insight would be greatly appreciated!
