Error while installing torch about torch.github.io HOT 2 OPEN

Are you on Arch Linux? Looks like GCC 6.1.1 doesn't play nicely. If you have CUDA installed, you can edit the install.sh file to run with GCC/GCC++ provided by CUDA.

I changed

# If we're on OS X, use clang
if [[ `uname` == "Darwin" ]]; then
    # make sure that we build with Clang. CUDA's compiler nvcc
    # does not play nice with any recent GCC version.
    export CC=clang
    export CXX=clang++
fi

because the latest Arch provided clang doesn't seem to work so I don't care about it to:

export CC=/opt/cuda/bin/gcc
export CXX=/opt/cuda/bin/g++

And also because Arch installs cuda to /opt/cuda, I changed the path_to_nvcc to:

path_to_nvcc=$(which nvcc)
if [ $? == 1 ]; then { # look for it in /usr/local
  if [[ -f /opt/cuda/bin/nvcc ]]; then {
    path_to_nvcc=/opt/cuda/bin/nvcc
  } fi
} fi

When installing other stuff with luarocks I get the same errors, so to get around that for example...

CC=/opt/cuda/bin/gcc CXX=/opt/cuda/bin/g++ luarocks install inn

Hope this helps a bit. Keep in mind this would only work on Arch Linux with cuda installed. Good luck!

Thanks @skatardude10 for the response.

Yes I was on Arch Linux, but I had some urgent work so I switched to Ubuntu for time being. But since I am an Arch fan, I will return to it soon and try installing the torch with the given suggestion.

In the meanwhile, I hope this would also help other Arch fans out there. 😄
