Sorry, the latest upstream release is 5.0 however, 4.0 and later
cannot be built in current cygwin because LLVM package is old.
This update is up to 3.1.
- Enable CUDA support.
Curiosity, how do we support CUDA on Cygwin ?
nvidia cuda toolkit is used in build stage of user programs.
Although this is not very desirable for cygwin package, I thought
that the advantage of being able to use the GPU was greater than
the disadvantage.
However, on the second thought, cuda support should be a separeted
package from the base package, and suggest installing cuda toolkit
in the install stage of of that package.
Let me consider a bit. If you have any idea, please let me know.
Please note CUDA is Nvidia proprietary closed source - I do not think we can or
should touch it when OpenCL 3+ supports Nvidia devices.
Fedora does not support CUDA although others do in their non-free "sources".
We do not touch CUDA itself or distribute its binaries, but just use binaries
distributed by NVIDIA. Source code in pocl is not NVIDIA proprietary. In that
sense, cygwin itself uses microsoft proprietary closed source modules.
Cygwin provides and runs open source tools, headers, and libraries to perform
the builds and execution, calling proprietary interfaces to support POSIX.
So, enabling CUDA support in pocl should also be allowed, I think.
I believe not if the Nvidia tools do not have sources available to build with
Cygwin tools built from sources.
