the benchmark run good , ascii graphics is working

Hi @cerberuscl,

you need a Linux desktop environment with X11 to run with INTERACTIVR_GRAPHICS. The make.sh compile script does not detect a monitor on your system, so it compiles without linking the X11 library, and then compiling fails if you have INTERACTIVR_GRAPHICS enabled. If you have only a command line interface available, use INTERACTIVR_GRAPHICS_ASCII or only CLI interface and render images to hard drive with enabling the GRAPHICS module.

Kind regards, Moritz
