Error linking cublas

[subversive-owl]

On a Linux laptop with NVIDIA proprietary dependencies installed, all necessary libraries link properly except for cublas.

Note that building with only native extensions works, but examples return immediately without a result in this case (#5).

log

The initial command was cargo build --release.

[drahnr]

Can you provide a Dockerfile which reproduces the issue? I'd be really happy to dig into this and add it to CI as a test.

[subversive-owl]

I'll have a Dockerfile at the end of the day.

I'm making a docker base image since there is none for PureOS8, which should be ok to upload to the public registry.

[drahnr]

Cool! Concourse CI also works with a rootfs.tar.xz so if you have that, I should be all good too :)

[subversive-owl]

Here's an image: https://hub.docker.com/r/subversiveowl/pureos8-base/

Now I just need to write a dockerfile...

When hitting this issue, consider exporting the following:

export CUBLAS_LIB_DIR=/opt/cuda/lib64
export CUDNN_LIB_DIR=/opt/cuda/lib64

as per [1], [2].
