The package includes a Makefile for gcc, which has been verified on

32-bit Linux systems. The code can be compiled by entering the directory

"c-code" and typing the command: make. The resulting encoder/decoder/renderer

executables are named "IVAS_cod", "IVAS_dec", and "IVAS_rend". All reside 

in the c-code directory.
