Ubuntu runtime errors

[flitter]

I used the sticky thread to build makemkv as described and I get these output to the console that I ran it from when I run it. I also installed via heyarje repository and get the same messages.

Code: Select all

$ makemkv

I searched for the first message and found one post but didn't see any replies. Any ideas?

Edit to include uname -a:
