Work around.

Open your .bashrc:

gedit ~/.bashrc

Add this line to the end of the file:

alias g++='g++-6'

Then source your .bashrc:

source ~/.bashrc

One liner:

echo "alias='g++=g++-6'" >> ~/.bashrc; source ~/.bashrc

This doesn't actually solve it. Well... it *does* but not enough so. An alias is not a sufficient fix for something like this. – Slava Knyazev Sep 09 '16 at 21:31

A more proper fix for this would be to make a symbolic link for g++-6 to g++. This will ensure compatibility with many installers and other applications.

To do this:

sudo ln -s $(type g++-6 | grep -oE '[^ ]+$') /usr/bin/g++

This will get the path to g++-6 and create a symbolic like using it to /usr/bin/g++
