Cant find -lcudart #25

Closed dineshadepu closed 5 years ago

dineshadepu commented 5 years ago

Hi all.

I want to contribute to this project. I just got my gpu. I installed nvidia drivers and cuda tool kit.

 --------------------------------------
 dinesh@LAPITOP (master #) /home/dinesh/prog/rust/cuda_rust_check $  
|  Dell Laptop=> nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2018 NVIDIA Corporation
Built on Sat_Aug_25_21:08:01_CDT_2018
Cuda compilation tools, release 10.0, V10.0.130

I added cuda libraries as given in readme.

# cuda installation
export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}$
export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export CUDA_LIBRARY_PATH="/usr/local/cuda-10.0/lib64"

I want to show that the libraries are available at here 

 --------------------------------------
 dinesh@LAPITOP /usr/local/cuda $  
|  Dell Laptop=> ls
bin  extras   lib64      libnvvp  NsightCompute-1.0  nvml  README   share  targets  version.txt
doc  include  libnsight  LICENSE  nsightee_plugins   nvvm  samples  src    tools

Now when I run the example given in readme I get,

How to fix this?

rusch95 commented 5 years ago

See issue #15

@bheisler Want me to submit a PR updating the instructions for this in the README

dineshadepu commented 5 years ago

This fixed my problem.

Ideally, cuda-sys should be able to find the libraries on its own - see https://github.com/rust-cuda/cuda-sys/issues/7.
