Trying to run standalone (headless) on Linux (Ubuntu) - failed at first hurdle

[panagiotis m]

Hello Ben,

For libfreetype, I think you should do:

sudo apt-get install libfreetype6-dev

Also, yes, the "official" supported Ubuntu distros for LC are 14 and 16
LTS. However, LC standalones built from 9.6.6 should run on Ubuntu 18 and
above as well.

Tomorrow I'll try to set up an Ubuntu 18 VM and give it a try.

Kind regards,
Panos
