Cannot build NVVM using LLVM_CONFIG

[gastrodon]

I'm trying to build the add example, using llvm70 on x86_64-unknown-linux-gnu. I'm unable to get NVVM to build, it looks like a some kind of version mismatch? Lots of incorrect usage, and unresolved imports.

I've included the entire cargo build out: https://pastebin.com/rzggDiNU

The codegen backend requires you to use the same nightly rust version as in our repo, currently nightly-2025-03-02. Add a rust-toolchain file to your workspace like ours and include the components listed as well.

Edit: just realized your using the version 0.3 from crates IO, which is currently on a much older nightly, and may not build properly with its current dependencies. Try using what’s currently in main branch.

Hi @gastrodon , I would suggest use the current main branch's container support to try the add example.

https://github.com/Rust-GPU/Rust-CUDA/tree/main/container

Quote the README here:

Use Rust-CUDA in Container Environments

# The distribution related Dockerfile are located in `container` folder.
# Taking ubuntu 24.04 as an example, run the following command in repository root:
docker build -f ./container/ubuntu24/Dockerfile -t rust-cuda-ubuntu24 .
docker run --rm --runtime=nvidia --gpus all -it rust-cuda-ubuntu24

@gastrodon did main work for you?

Hey thanks for the reply. The thing about the rustc-toolchain file makes sense, I'm currently indisposed, and will see what a build looks like when I'm back on my computer with a cuda-compatible GPU.
