Official Release of Ethereal 12.00

[mvanthoor]

Congratulations with the new release I hope/dream to ever get my own engine within the top 10. You did well

What Vinvin is pointing out with

Typical search with missing "best" move at some depth : "27/50-" , "27/55-" , "29/65-" , ...
It's always a depth with a minus sign at the end.

Is as expect, as minus signs indicate a fail low, which states that all moves are worse than some score, and we are in no position to say which is better. Up until recently, SF also would have reported no move in this case.

I've never had any issues under Arena or Cutechess, and I've never seen a crash of a disconnect as a result of output not being produced. Without seeing up your the GUI that you use myself, and verifying that the issue is reproducible, there is not much I can do. This is the first I've heard of such issues, despite another user suggesting it to be a long running occurrence. I'm not about to buy either product, but if someone can show an issue with a freely available GUI -- thats something I can work on.

I think what people are trying to point out here is that the log doesn't show a 'bestmove' command from the engine in reply to 'stop'. Failing to send the 'bestmove;'' would be a violation of the UCI specs, and it is quite conceivable that some GUIs would hang forever while waiting for it.

Any progress on this?

No clue, sorry. A best move is certainly sent, so it must be an issue with the output not being flushed. However, I explicity fflush(stdout) after reporting anything to the UCI interface. So unless someone knows of some oddity in this, I can't resolve it, primarily because I can't reproduce the issue in any of my GUIs on any of my machines.

Can you confirm that the engine is still running? IE the binary still shows up in your task manager, despite not reporting the best move to the GUI?

[Krzysztof Grzelak]

I'm sorry to ask where I can find engine versions Ethereal 12.01.

If you are able to compile source, you can get the latest source from here : https://github.com/AndyGrant/Ethereal

Otherwise, I could compile binaries for you and upload them somewhere for you to grab.

Whichever works for you.

I apologize to you but I can not program.

You don't need to program, just setup a compiler.
This https://github.com/glinscott/fishtest/w ... on-Windows step-by-step instructions with some abstraction should also work for Ethereal and several other engines published at github.

When I compile Ethereal on Linux, everything seems fine. But when I run your *exe files on Wine, I get this:

After the stop command, no bestmove but Ethereal is still alive and properly reacts on the quit command.

Ethereal does not work under Wine, and there are no plans to resolve that at this time.
