Are you planning to upgrade g++ to 4.9 sometime?


the regex library isn’t supported under 4.8.4, which seems to be what I get currently.



You’re welcome to upgrade it yourself in the many ways one does on ubuntu. :slight_smile:


Like this
sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt-get update sudo apt-get install g++-4.9


Thanks for the directions. That worked fine. People might want to note that you probably then want to change the link from /usr/bin/g++ to the new version of g++
