Greg created a new topic ' Problem buidling kstars on Mint 18.3' in the forum. 1 month ago

I have a Linux Mint system that was on Xenial. I'd been building kstars/Ekos on it for a few years up until maybe 6 months ago. Since then, I could not get kstars to compile. As my other (newer) systems worked fine I decided to upgrade to Bionic 18.3. Unfortunately this did not help, and I am getting the same error which is below. I forced a re-install of all dependencies and this did not help. I also re-downloaded the git repository and started fresh with no success.

Any ideas what is causing this and how to fix it?
