compiling marlin for graphic display

I'm trying to put a discount graphic display on my robo3d r1 plus. I downloaded from marlin the proper firmware. I take it to my arduino ide and it compiles with no errors. I commented out the LCD and uncommented the discount graphical display, and it faults out while compiling. I did include ( #include U8glib.h ). The compile faults out when I include U8glib.h. Even if I just comment out the LCD, the compile will fault out. I went to sketch and added my zip lib ( U8glib.h), and it shows at the bottom of my library list.
Please, any ideas how to get my discount graphics controller to work.

How do I know when I get an answer?
Do I stay logged into this page?
How do I get back to this page to get an answer?
I see no procedure for operating in here.

I am new at this...

Firstly you need to post the error message so we have some chance of giving you the correct information.

Then you need to provide anything that might be helpful to know like. What operating system are you using. What version of the Arduino IDE. Where you got the firmware from (in case it was not from the official marlin site). What controller you using. etc
Some of these are answered in the error log.

Are a bit of googling I found that the robo3d R1 + seems to come with a standard ramps/mega2560 controller.
