Hello everyone!

I am having some issues with CUDA.jl. At first I thought it was an issue with the drivers from NVIDIA or the CUDA installation on my PC, so I uninstalled the drivers, the cuda toolkits, everything. However when I installed the nvidia-driver-470, it identifies a CUDA 11.4 instalation before I re install CUDA.

Anyways, CUDA seems to work well when I run some pytorch codes. The problem is when I try to using CUDA.jl. So I tried running `Pkg.test(“CUDA”), I get the following

Does anybody know what could be wrong with my settup? Thanks already 🙂

Update your packages: this is [Both ExprTools and LLVM export "parameters" · Issue #214 · JuliaGPU/GPUCompiler.jl · GitHub](https://github.com/JuliaGPU/GPUCompiler.jl/issues/214), caused by a new export in ExprTools.jl.

This worked! Thanks so much!

Hi Maleadt,

I have the same problem when testing CUDA

```julia
 Testing Running tests...
ERROR: LoadError: LoadError: UndefVarError: parameters not defined
Stacktrace:
  [1] call!(builder::LLVM.Builder, rt::GPUCompiler.Runtime.RuntimeMethodInstance, args::Vector{LLVM.ConstantExpr})
    @ GPUCompiler ~/.julia/packages/GPUCompiler/XwWPj/src/rtlib.jl:57

```

I have still updated both packages

```julia

(@v1.6) pkg> update LLVM
    Updating registry at `~/.julia/registries/General`
  No Changes to `~/.julia/environments/v1.6/Project.toml`
  No Changes to `~/.julia/environments/v1.6/Manifest.toml`

(@v1.6) pkg> update ExprTools
    Updating registry at `~/.julia/registries/General`
  No Changes to `~/.julia/environments/v1.6/Project.toml`
  No Changes to `~/.julia/environments/v1.6/Manifest.toml`

```

but this did not change anything when testing CUDA. Are there further steps neccessary?

Problem already solved after deleting Manifest.toml and Project.toml and installing all needed packages again
