Question

I am trying to compile my first CUDA 5.0 project I took the template sample. I have not gotten it to compile it yet and as it shows two errors, I have compared the project settings with those of the template project and they appear to be consistent so I’m stumped. Here are my two errors.

The first occurs when I try to call my kernwl it marks the '<<<'

Error 32 error : expected an expression D:\Virtualbox
Data\Assembla\gul\antares
software\AntaresVisualizerCuda\AntaresVisualizerCuda\kernel.cu 584

Its possible that thar would be fixed by solving the next error:

Error 33 error MSB3721: The command “”C:\Program Files\NVIDIA GPU

Any ideas on this one?

Answer 1

Your kernel call within the comments looks like this:

tracePixel<<< gridP, threads >>>(d_screenOrigin, u_unit, d_u_dir, v_unit, d_v_dir, d_cam_pos, d_minpoint, d_maxpoint, gridLength, min, scale, d_grid, d_buffer,);

If that is indeed what you have and not a typo, then there is an extra ‘,’ after d_buffer which should not be there. Either that or you’re missing an argument.
