Stockfish 18 Bookworm

[Peter Eßer]

Hello. First of all, thank you very much Robert for your reply! Unfortunately, I'm stuck due to a lack of knowledge and need expert help.

Previously, a compiled version of Stockfish was provided as an ISO or IMG file. I wrote this to an SD card using Rufus. I have a Raspberry Pi 5 and a DGT 3000 watch.

Hello Peter,

sorry for my late answer i was very busy.

So if you need further assistance with compiling stockfish18 on your device you need a terminal window via ssh from your local pc or in x-windows environment.

you should first check and install the compiler:

sudo apt-get install build-essential

then download the source files:

wget https://github.com/official-stockfish/Stockfish/archive/refs/tags/sf_18.zip

then unzip the downloaded file:

unzip sf_18.zip

then change to the new source directory:

cd Stockfish-sf_18/src

then start the compiler this will need some time to compile all:

make -j profile-build

when the process finished without errors you should have three new files. one named stockfish thats the engine an two nnue files nn-*.nnue

you must copy these files to the correct directory:

cp stockfish /opt/picochess/engines/aarch64/NNUE/

cp nn-*.nnue /opt/picochess/engines/aarch64/NNUE/

when you are done with that come back here.

Hello. Thanks for your effort! Unfortunately, as a layperson, I can't offer any support. I'm also unable to follow your instructions! I've always used Rufus to put the provided Stockfish ISO onto an SD card and inserted it into my Raspberry Pi 5. I admit, it's very convenient. So I'll have to wait until someone has time to upload Stockfish 18 as an ISO. Regards, Peter
