SiftGPU problem

Hi everyone,
I am new to cuda and gpu. I am using gpu to accelerate the sift algorithm which is used in computer vision. I found a great library called SiftGPU from Dr Chang Chang Wu. Howevery,
during the compilation of the library, I got several errors and warmings. So could some one help me?

  1. Advisory: Loop was not unrolled, inline assembly
  2. /usr/bin/ld: cannot find -lGLEW

thanks a lot!
