Can’t find Stockfish in scope

[mayweed]

Hello Niklas,
Am trying to update my current Pi setting with the new rust fishnet and while running cargo i got this error:

Compiling fishnet v2.2.1-dev (/home/pi/fishnet)
error[E0425]: cannot find value `STOCKFISH` in this scope

    |                  ^^^^^^^^^ not found in this scope

For more information about this error, try `rustc --explain E0425`.
error: could not compile `fishnet`

To learn more, run the command again with --verbose.

Is this because there is no official release of SF for armv7? Se is there an option to pass a self compile sf?

Yes. The current decision is to draw the line for platform support at 64 bit. To check, can you please share the output of ./self-compiled-stockfish bench? I suspect it will be too slow.

Here are the 3 last lines:

Thx

Thanks. Currently, the absolutely minimum acceptable nodes/second is 375000. Looks like the Raspberry could achieve it when using multiple threads, but barely, and it would probably get very hot, unless actively cooled. I don't think it's worth it.

The reason it's now harder to use custom Stockfish builds is that since version 2 the goal is to deliver exactly identical analysis no matter which fishnet client does the analysis, so the exact reproducible builds of Stockfish are tracked in Git.
