*Fixed the compiler errors thanks to Antonio, also fixed the malformed UCI ID-String

On Ubuntu 16.04 I get:

tamas@tami:~/bin/Opental$ ./opental
./opental: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by ./opental)

[Scally]

in main.cpp add "name" in line 39 between "id" and the engines name. like this:

Code: Select all

printf("id name OpenTal 1.1"   [...]

the UCI protocol expects the ID string to look like this.

That’s it, brilliant!

Thanks very much

Al.

Hi Bajusz,

You get that error because the executable is compiled with a newer version of glibc/libstdc++ than yours.
You can compile opental yourself following instructions of my earlier post.

Kind regards,

Antonio

that is quite possible because I used ubuntu 17.10 with the latest libraries.

Maybe someone here has a solution to getting this engine operable in a linux environment. With much online searching I didn't find a solution. Maybe it is out there and I missed it.

I made a compile for macOS - a few changes were required as I recall , but generally if it can be done for macOS , it can be done for Linux.

BTW, for Brendan and Ulysses: iCE 3.0 is a very interesting engine, worth testing and playing with.

Thanks! Will check it out!

I still have to pinch myself now and then when I realize there are so many strong and interesting engines stronger than Zappa Mexico II that I still haven't checked yet

Is this engine any different from rodent 3 using the Tal personality?

The Rodent III Tal personality should be a little more conservative than OpenTal. It will play in Tal's style, but might shy away from the really speculative sacrifices Tal played during his career (which engines these days just laugh at, although his GMs opponents lost to them).

OpenTal will play them to with the intention of completely emulating Tal - "weaknesses" and all!

The end user is likely much weaker than Tal's opposition (OpenTal is designed for humans to train against) and can experience playing against true Tal craziness.

BTW, for Brendan and Ulysses: iCE 3.0 is a very interesting engine, worth testing and playing with. Thomas Petzke left a great deal of endgame knowledge in the engine, even when he discovered that, Elo wise, it was not worth much. But it's a gift for analysis and for use without TBs. Thomas' blog is also worth reading.

Thanks, will check it out!

*edit* nothing to see here

I get this:

/usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by ./opental)

I tried sudo apt-get install GLIBCXX but it is not available in the defaults repositories.

Where can I find this library ? Which repository ?
