OpenCL C FFI bindings for the Rust programming language.
Rust FFI Bindings to the Khronos OpenCL C language headers, see the OpenCL Resource Guide.
OpenCL Packages
The static API for OpenCL versions and extensions is controlled by Rust features such as "static", "CL_VERSION_2_0" and "cl_khr_gl_sharing".
Rust deprecation warnings are given for OpenCL API functions that are deprecated
by an enabled OpenCL version e.g., clCreateCommandQueue is deprecated whenever
"CL_VERSION_2_0" (or above) is enabled.
The Rust FFI files attempt to match the format and layout of the original C source files instead of bindgen output files to ease maintenance.
bindgen ../OpenCL-Headers/CL/opencl.h -o opencl.rs -- -I ../OpenCL-Headers/CL
The library is declared no_std.
OpenCL requires that an appropriate OpenCL hardware driver(s) and an OpenCL Installable Client Driver (ICD) are installed.
OpenCL GPU hardware driver(s) are installed with graphics drivers by the main manufacturers: Nvidia, AMD and Intel.
However, an OpenCL ICD must usually be installed manually by:
- a Linux package manager, e.g.,
sudo apt-get install intel-opencl-icd - or a Windows download and install from https://www.intel.com/content/www/us/en/developer/articles/technical/intel-cpu-runtime-for-opencl-applications-with-sycl-support.html
Note: you do not need to install an OpenCL ICD from the same manufacturer as your hardware.
In general the more up to date the OpenCL ICD, the better.
