I was having difficulty running install.packages("forecast") after a new install of CUDA 9.1 on Ubuntu 17.10, with the error

#error -- unsupported GNU version! gcc versions later than 6 are not supported!

I fixed this problem by first following instructions here running from command line

sudo ln -s /usr/bin/gcc-6 /usr/local/cuda/bin/gcc

I then got the error 

gcc: error trying to exec 'cc1plus': execvp: No such file or directory

This is due to GCC 6 not having a G++ to go with it. Simply install G++6 with:

sudo apt-get install g++-6
