Rust binding to [CUDA Driver (`libcuda.so`)](https://docs.nvidia.com/cuda/cuda-driver-api/index.html)

and [Runtime (`libcudart.so`) APIs](https://docs.nvidia.com/cuda/cuda-runtime-api/index.html)

This crate does **NOT** include CUDA itself. You need to install on your own.

CUDA Installation

------------------

- You should install CUDA from [the official installer](https://developer.nvidia.com/cuda-downloads).

- or use [`nvidia/cuda` container](https://hub.docker.com/r/nvidia/cuda/)

  - This container does not add `libcuda.so` to dynamic link path.

    You need to add it to your ld path `LD_LIBRARY_PATH=/usr/local/cuda/lib64/stubs` or using `ldconfig`.

CUDA_LIBRARY_PATH environment variable

--------------------------------------

- If you use system installer (e.g. `apt`, `yum`, `pacman`, and so on), the install path may be different.

- `$CUDA_LIBRARY_PATH` (e.g. `/opt/cuda/lib64`) environment value adds paths to the list of library searching.

  - `$CUDA_LIBRARY_PATH` is not required on Windows when CUDA is installed via [the official Windows installer](https://developer.nvidia.com/cuda-downloads).

- To verify that cuda-sys can find your CUDA installation, you can check that the `CUDA_PATH` environment variable has been set.

Q & A

------

Q. Program does not *start* (can be compiled) with following error message:

```

error while loading shared libraries: libcuda.so.1: cannot open shared object file: No such file or directory

```

A. Driver API (`libcuda.so`) is sometimes installed in a separate directory. You need to find it, and add to `LD_LIBRARY_PATH`:

```

LD_LIBRARY_PATH=/usr/local/cuda/lib64/stubs

```
