compile a Linux binary ?

[tissatussa]

eg. to use in CuteChess : how to compile Kairuku ?

[ i'm on Xubuntu 22.04 ]

Hi, does CuteChess accept shell scripts as executables? If so it's pretty easy, build the project and make a shsll script running the engine .jar. If not it will become more complicated. Please let me know if you can get it to work, I might be able to provide further assistance like detailed build instructions if you're not familiar with the JVM ecosystem.

..if you're not familiar with the JVM ecosystem..

indeed, i'm not into JAVA .. often i find a .jar asset file and i run it by java -jar [jarfile], CuteChess can handle that, although i often create a small run.sh file contaning just that one line - sometimes this is the only way that works for me in CuteChess, i don't know why .jar files differ here ..

note: i'm on Linux ..

Hi, please try kairuku-engine/target/kairuku-engine-1.0.1-SNAPSHOT-jar-with-dependencies.jar

[tissatussa]

Hi, please try kairuku-engine/target/kairuku-engine-1.0.1-SNAPSHOT-jar-with-dependencies.jar

sorry, i don't see that file in the package ..

it contains a pom.xml file, which i can (normally) use to compile a .jar file, but i get errors .. i can supply a log .. do you have a .jar ASSET ?

[marvk]

I thought you were able to compile successfully.

Make sure you have Maven and JDK 11+ installed on your machine.

You might need to do the following steps so that the build will work:

• Change Line 25 of ./pom.xml to <lombok.version>1.18.32</lombok.version>.

• Delete Lines 63-81 of ./queensgambot/pom.xml.

Then, run mvn clean package in the projects root directory. If the build works, the .jar should be present.

thanks for this info, now the compilation went well :

$ java -version
openjdk version "21.0.2" 2024-01-16
OpenJDK Runtime Environment (build 21.0.2+13-Ubuntu-122.04.1)
OpenJDK 64-Bit Server VM (build 21.0.2+13-Ubuntu-122.04.1, mixed mode, sharing)

i changed the pom.xml as you wrote and i get your mentioned .jar file, but it malfunctions in CuteChess .. i see the cause when running in terminal :

$ java -jar ./kairuku-engine-1.0.1-SNAPSHOT-jar-with-dependencies.jar
uci
id name kairuku
option name ply type spin default 7 min 1 max 7

compare this output to another (working) .jar :

$ java -jar ./Eubos_v3.5-asset.jar 
uci
id name Eubos 3.5
id author Chris Bolt
option name Hash type spin default 256 min 4 max 4000
option name Threads type spin default 1 min 1 max 4
option name Move Overhead type spin default 10 min 0 max 5000
option name Lazy Threshold type spin default 275 min 0 max 1000
uciok

id name and id author are basic, these lines always appear.
and the UCI protocol states the uci command should end with uciok !

[tissatussa]

btw. your code has some uciOK() function but it seems that function is not called .. i'm not into Java though ..

[tissatussa]

did you address the uciok issue yet ?
or was i wrong about that ?

[marvk]

I think I fixed that at some point, locally when using the engine to play my new engine. Need to get that off an old HDD though, I'll hit you up when I get around to it.

[marvk]

@tissatussa Hi, just pushed the fix, please check again.

[tissatussa]

..just pushed the fix, please check again..

congrats !
i just compiled the newest source and all went well : after i did the same changes in those pom.xml files, i get a valid jar file (4.6 Mb) and indeed it does uciok ! CuteChess is happy now and Kairuku won its first game !

i propose you update those pom.xml files and give Kairuku a version number.
it would also be convenient to supply a .jar asset for download.

btw. the dates of your source file(s) didn't change on GitHub, so it's not clear you made this fix .. how does this work ? (i've no experience with PR's etc.)

[tissatussa]

i let Kairuku play a few games and suddenly it had a disconnection in CuteChess GUI :
