Error installing Torch on OS X Sierra - CUDA 8

[NataliaDiaz]

I am using Mac OS Sierra 10.12.4, CUDA 8, on 8GB RAM, and I get this error when doing
torch user$ ./install.sh:
...

[kabrio]

here too :(

@kabrio @NataliaDiaz CUDA 8 doesn't support latest Xcode. You will need to downgrade it to an older version.

[pavanky]

FYI, here is how you downgrade Xcode to the right version: arrayfire/arrayfire#1384 (comment)

[NataliaDiaz]

I have followed the steps and unfortunately keep getting same error as above :(
clang --version Apple LLVM version 8.0.0 (clang-800.0.42.1) Target: x86_64-apple-darwin16.5.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin

[pavanky]

@NataliaDiaz did you try deleting the build directory before trying again ?

[NataliaDiaz]

yes I did. My clang version is now:
Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin16.5.0

I was having the same issue. The renaming method specified here seems to fix it for me: arrayfire/arrayfire#1384 (comment)
