Cannot create an RGBImage instance

[Rambunction]

Right now our robot doesn't have a camera on it so we're trying to run a local program with the wpilibj libraries. We're loading an image taken from last year onto the program but we can't get it to do anything. We simplified the code down to just the declaration:

new RGBImage();

Which results in this error:

What are we doing wrong here?
