Revert Apple Clang Version For NVCC

Question

I am trying to run NVCC to compile a CUDA program on my Mac.

When I try to run NVCC, I am receiving the following error: \"nvcc fatal : The version (\'70300\') of

Answer 1

80100 can work with some nvcc programs

I used "80100" and nvcc work for some of my other programs.

... but not sample

install CLT 8.2 (Command line tool from Apple) it is sort of ok with message about "command line tools instance"

I google and see a discussion about this (https://github.com/arrayfire/arrayfire/issues/1384) about array fire nvcc issue and thanks to the hint to switch to CLT 8.2, the last version not current one. It is sort of ok with warning message about "command line tools instance"

Need to use "sudo make" to compile sample code:

1. Go to https://developer.apple.com/downloads/, log in and then download http://adcdownload.apple.com/Developer_Tools/Command_Line_Tools_OS_X_10.11_for_Xcode_7.2/Command_Line_Tools_OS_X_10.11_for_Xcode_7.2.dmg, and install, as was suggested by fabregaszy.
2. Run the following command to switch to the old version: sudo xcode-select --switch /Library/Developer/CommandLineTools
3. Run the following command to quickly check clang version: clang --version

Answer 3

I came into the same issue.

I think the old command-line tools which can be downloaded from https://developer.apple.com/downloads/

may solve this issue.

Updated:

I downloaded from the link below and installed, the clang version was successfully reverted to Apple LLVM version 7.0.2 clang-700. But please keep an eye on your OS X version.
