NVCC does not support Apple Clang version 8.x

[mlloreda]

Error message: nvcc fatal : The version ('80000') of the host compiler ('Apple clang') is not supported

Steps to fix:

1. Log in to https://developer.apple.com/downloads/
2. Download Xcode CLT (Command Line Tools) 7.3
3. Install CLT
4. Run sudo xcode-select --switch /Library/Developer/CommandLineTools
5. Verify that clang has been downgraded via clang --version

Edit: Update to 7.3 and fail at 8.0

This issue does not affect CUDA >= 8.0

First of all, CUDA 8.0 isn't widely available yet as it hasn't been officially released. Second, even CUDA 8 doesn't work with the current version of the Apple LLVM (version 8.0.0). It produces the following error message:
nvcc fatal : The version ('80000') of the host compiler ('Apple clang') is not supported

^Running into the same error message, @samedling

Thanks for your feedback. Unfortunately, this is an issue for CUDA to handle rather than ArrayFire. We are just a consumer on this front. That's why we have marked it as a known issue.

CUDA 8 has been release as of today. However, as far as I can see, there is no download available for OSX.

[shehzan10]

CUDA 8 for OSX has been released and supports clang version 7.3.
It however does NOT support XCode 8/Clang 8.

Editing this issue to reflect that.

Downloaded CLT from https://developer.apple.com/download/more/.
another issue occurred:

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

@henrythung it looks like you may need to install XCode if you haven't already done so.

I have CUDA 8.0.46, OS X 10.12 and Xcode 8.1 but still have the same issue.

[admercs]

To switch Xcode CLT back to 8.1 run this:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

@Sitin the issue description says you need to downgrade to 7.3 for CUDA to work.
