Compilation errors on Ubuntu 16.04 #516

Closed ghost closed 3 years ago

If I try to compile the git repo on Ubuntu 16.04, I get these errors:

The compile process finishes and I am able to run sam. Are these warnings significant? If so, how can I resolve the issue?

I am bound to use Ubuntu 16.04 for work purposes.

If it finishes and the programs work, I wouldn't stress on the compiler warnings: they're harmless. Ubuntu 16.04 is pretty old, and it doesn't make a lot of sense to special-case it.
