error: could not compile `ocl3` (bin "ocl3") due to previous error
error: failed to compile `ocl3 v0.1.0 (C:\Users\rdas6\OneDrive\Desktop\codespace\rust\ocl3)`, intermediate artifacts can be found at `C:\Users\rdas6\OneDrive\Desktop\codespace\rust\ocl3\target`

here is my cargo.toml

[package]
name = "ocl3"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
opencl3 = "0.8"

I am having opencl Compatiable drivers

+ I have downloaded the OpenCL from https://developer.nvidia.com/opencl but not sure where to place the OpenCl.lib

Rust Version

rustc 1.71.0 (8ede3aae2 2023-07-12)

Any assistance or insights on resolving this issue would be greatly appreciated. Thank you!

[Leikoe]

this worked for me PlasmaPower/nano-vanity#16 (comment)

[Dainerx]

Add LIB as system env variable. It should contain the path of the OpenCL.lib you installed. For my case, on my Windows machine, LIB resolves to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.3\lib\x64

Btw, this issue has nothing to do with this crate.

[kenba]

This issue seems related to dynamic linking, see: kenba/cl3#36 and kenba/opencl-sys-rs#2.

The fix for kenba/cl3#36 was to add static and dynamic features and to make dynamic linking the default feature. I believe that this crate should incorporate the change from cl3 to fix this issue.
