I’ve been using CUDA.jl on windows so far, today I switched to Manjaro, and installed the julia 1.6.1, and tried to install CUDA.jl.  
But there is an error for not founding the lib:

```julia

```

It’s a fresh install, I tried to purge everything in .julia folder, and the problem remains, there is no any download error.  
And aslo I checked the file it claimed not found, it exists, and it has read permission and can be run as program.  
I checked other package involve using artifacts, like Plots, it’s working fine.

I stumbled upon the same error trying to use ReinforcementLearning.jl on Arch Linux with linux kernel 5.12.15 and Julia 1.6.2 and don’t (yet) know how to fix this.  
Precompilation fails because the package `LLVM` fails to precompile `during initialization of module LLVMExtra_jll` (as can be seen in your stacktrace, just wanted to confirm this is exactly what i see too).  
I’m replying in order for this topic to gain some traction, and maybe someone knowing how to fix this comes around.

I had the same issue on both Manjaro and Arch and I fixed it by installing the aur `julia-bin` package instead of `julia` as explained in [LLVMExtra JLL doesn't support USE\_SYSTEM\_LLVM · Issue #253 · maleadt/LLVM.jl · GitHub](https://github.com/maleadt/LLVM.jl/issues/253)

Thank you! Worked for me.
