New release: rofChade 2.1

It crashes the first time you load it , yes. You need to configure it to fill in the Sygygy path, then it works without crashing.

Ok that worked - but all my other engines in arena are happy with the <empty> setting for Syzgy tableses as i dont use tablebases

I tried to find out what is happening in Arena, and it seems that when you add rofChade as a new engine and don't set the specific parameters yet in Arena, Arena sends a setoption command for the SysygyProbeDepth without specifying a value:

Code: Select all

setoption name SyzygyProbeDepth value

rofChade doesn't like that, it expects a value after "value" and it crashes..... When you define the uci options for the engine, SysygyProbeDepth gets its default value in Arena (0) and after that Arena will send 0 as value. I checked the "uci specification document" and it states that with the setoption command you should always specify a value, except for button type options, so technically I think it's an Arena bug..

However, it's also not so nice to let the engine crash when this happens, so I will fix this in the next version.

Thanks for sharing the info!

Hi Ronald,

When can we expect a Raspberry Pi binary?

Thanks,

Al.

Hi Al,

I just added a Raspberry Pi version to the download page on rofChade.nl. I build and tested it on my DGT Pi and it seems to work.

Let me know if it works,

Ronald

Just noticed this post containing some issues regarding PyChess can't install rofChade.
This is because PyChess fails to parse the invalid(!) option line rofChade emits:

option name SyzygyProbeDepth type spin default default 0 min 0 max 127

Notice the 2x "default"!

[Ronald]

option name SyzygyProbeDepth type spin default default 0 min 0 max 127

Notice the 2x "default"!

Oops......

This is to make really really sure the default value is 0....

Stupid mistake which probably also is the reason for the problem with Arena.

I'll fix it in the next version and thanks for noticing and sharing it!
