Hi Marc,
Sorry to hear you're having trouble getting Melkhior's running. I haven't tried it on Linux since it was released a year ago, I think that was on Ubuntu 20. I've just tried it on version 22 and I can't get it to run at all, which is odd. I'll try and find some time to look into it over the next few days, I might need to rebuild it. Have to say, I'm not a Linux person, so I'm not sure how far I'll get with it.
Cheers,
Rich.
