Issue with compiling Opengl and glut

i am trying to compile a program on my imac, that runs neural network using opengl and glut. i am using framework for mac to compile opengl and glut but still i get this error. i have a feeling that i am missing some library to compile.

Here is the output:

$ gcc gpu.c -o gpu -lfann -lm -framework OpenGL -framework GLUT

I think you're not including the proper code or library.

It looks like your code is related to the FANN library, but the linked page says:

The code is still expremental and is not included in the FANN library but is available for the user to try out if he wishes.

So, your -lfann won't help to get these functions defined, you need something else.
