Issue with global pointer

I am trying to display a picture on VGA and I have SDRAM with 128MB on hardware. But when I place large array off 220*240 pixels in the code it gives me the global pointer error.

I am getting this Error:

warning: Unable to reach (null) (at 0x00047ff4) from the global pointer (at 0x000342cc) because the offset (81192) is out of the allowed range, -32678 to 32767.

I saw that the solution might be to add -G0 in the compiler options. But I do not know how to do this in the Eclipse.

I can not find this option in the Eclipse IDE. Can someone tell me how do I add -G0 in the compiler options ? I need pictures or printscreens.

Help me please.
