I downloaded the latest code by git clone command. Then i followed the step to make. My log:

"helper_math.h" was removed in previous commit, but it is still included in some code file?? commented out this include line leads to other error message.

Thanks.

helper_math.h is from the CUDA toolkit, we had to remove it because of possible copyright issues. This means, it is now taken from the installed CUDA toolkit. Make sure that CUDA_SDK_ROOT_DIR is set in CMake. On my linux system it points to /usr/local/cuda/samples.

raymond00000 commented 7 years ago

thanks, right! I can build now.

Can you explain what below line mean?

Set up environment variable COMPUTE_CAPABILITY with the CC of your CUDA-enabled GPU

Thank a lot!

reini1305 commented 7 years ago

Right, we should probably document that better :) Depending on your graphics card, you can set the compute capability: https://en.wikipedia.org/wiki/CUDA#GPUs_supported

If you don't specify it, it will default to 3.5 which is the minimum necessary.

reini1305 commented 7 years ago

Can we close this issue?

raymond00000 commented 7 years ago

thank a lot!

i have set ' 'export CUDA_SDK_ROOT_DIR=$CUDA_SDK_ROOT_DIR:/usr/local/cuda-8.0/samples'' in '~/.bashrc' and then 'source ~/.bashrc ' but i still have this problem~/.
