R help - Jun 2022 - Install OpenCL

Hi everyone,

the installation of OpenCL on windows with CUDA 11.7 failed. I can set
up tensorflow in python and communicate with the GPU, so I assume CUDA
is set up correctly. OpenCL headers are also available through the CUDA
toolkit.

However, the package installation of OpenCL in R fails. There is not
much documentation available. Can anyone help with that please?

You will need a working OpenCL SDK with headers
and libraries for both i386 and x64

Set OCL to the root of the SDK

You can also set individial variables OCLINC,
OCL32LIB and OCL64LIB. If they are not set,
the default layout will be assumed.

Dear Quirin,

To be able to install OpenCL on 
ArchLinux, I needed to install 
opencl-headers first, because my system 
complained about CL/opencl.h ...  Maybe 
there is something like that on Windows 
... 

Best,
Rasmus

Admittedly, it's not mentioned in the package's INSTALL file, but as
the configure script says, you need to set the "OCL" environment
variable to the path where you have OpenCL SDK installed. Use
Sys.setenv() to set the variable before running install.packages().

Also, make sure that the OpenCL DLLs are available via the %PATH%
variable.
