CUDA 8.0 on Mac OS/X
November 30, 2016
CUDA 8.0 on Mac OS X 10.12 gave me the following error:
The version ('80000') of the host compiler ('Apple clang') is not supported
So there is a mismatch between the new Xcode 8.1 and the new CUDA 8.0.
$ make /usr/local/cuda/bin/nvcc -ccbin clang -m64 --std=c++11 -O2 -lineinfo --relocatable-device-code true -Xcompiler -arch -Xcompiler x86_64 -gencode arch=compute_30,code=sm_30 -o Main.o -c Main.cpp nvcc fatal : The version ('80000') of the host compiler ('Apple clang') is not supported make: *** [Main.o] Error 1 make: *** [map/Makefile.ph_build] Error 2
I had the following version of clang installed
$ clang --version Apple LLVM version 8.0.0 (clang-800.0.42.1) Target: x86_64-apple-darwin16.1.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
- Download the “Command Line Tools (OS X 10.11) for Xcode 7.3.1” from developer.apple.com.
- Install them
- Set them as the default with
sudo xcode-select --switch /Library/Developer/CommandLineTools
Now clang says it is version 7.3
clang --version Apple LLVM version 7.3.0 (clang-703.0.31) Target: x86_64-apple-darwin16.1.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin
nvcc works again.
Make sure that you do not update the developer tools again. Mac OS X will offer an update of the “command line tools” via the app store as soon as it detects that the older version is active.
Thanks to the developer blog of NVIDIA for pointing this out.
