During my installation of torch on Ubuntu 17.04, I ran into a few problems.

giving me something like

error -- unsupported GNU version! gcc >5 are not supported!

After I fixed this I got another error similar to here:

Gcc error: gcc: error trying to exec 'cc1': execvp: No such file or directory

Want to also add here that this is in conjunction with my cuda setup.

I fixed the first error by installing gcc-5:

sudo apt-get install gcc-5

next, it said it couldnt find cc1, so i did

which cc1

which returned a blank. This was because I didn't install g++-5

sudo apt-get install gcc-5 g++-5

we next want to make this our default gcc, so

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 1

and finally

./install.sh

in the torch directory works. This is similar to the approach here:

torch getting started that started it all: http://torch.ch/docs/getting-started.html

hope this helps someone
