rPi 2 & ofx, weird 'undefined reference' errors when building most projects

Hey gang. Yesterday was the first day I fired up a rPi 2 and ofx. All was going smooth. But now, I am unable to ‘make’ projects. The ONLY project I can make is videoGrabberExample, but I get this mess of errors for all other projects. I have no clue why videoGrabberExample will compile and run but no other examples will. As I said, this is my first time. Probably, it is something obvious. Thanks in advance :]

it goes on and on and on

reinstalled everything, fixed.
