Hello,

I’m trying to compile the “julia_gpu.cu” example in the “CUDA by example” textbook and encounter the following problem:

the command “nvcc -o julia_gpu julia_gpu.cu” returns the error message

I have libglut3 installed and can locate the gl.h, glu.h, glut.h etc. in /usr/include/GL.

I also tried “nvcc -o julia_gpu julia_gpu.cu -Iglut” and “nvcc -o julia_gpu julia_gpu.cu -IGL -Iglut” but get the same error message.

Any idea on what might be the problem?

OK, figured it out… I just typed a capital i instead of a lower case l. Stupid mistake…

Thanks anyway.

Just to make things clear, its supposed to be compiled as
nvcc julia_gpu.cu -lglut -lGLU -lGL

You also need to change
cuComplex( float a, float b ) : r(a), i(b) {}
to device cuComplex( float a, float b ) : r(a), i(b) {}

This is because functions that are declared as __device __ functions can only be called either from device functions or global functions.

Thanks xen_! I was a little stuck on this too. Just out of curiosity, did you learn those flags from the book or was that discovery from somewhere else? Cheers.

Thanks xen_! Feel lucky to find the answer.
It works for me.
