The error occurs regardless of what NNUE is used and no EXE is being generated.

Last but not least, could you tag the corresponding neural book to your future releases. I would guess that version 12 uses signalis-epoch15.nnue, correct?

[cosmobobak]

You appear to be compiling an old version of Viridithas. You'll have to compare dates on the viridithas releases and viridithas-networks releases if you want to match nets to releases. Old versions of viridithas find the network path via the EVALFILE environment variable, so set EVALFILE=signalis-epoch15.nuue if you want to compile with that.

[ArminiusTux]

Indeed version 12 was only accepting the signalis.nnue, so I renamed it and was able to compile it via:

EVALFILE="viridithas.nnue" RUSTFLAGS="-C target-cpu=native" cargo build --release --features syzygy,bindgen

The result however is unstable (also tested the latest commit and even without syzygy). After 12 seconds the viridithas.exe drops to 0 cpu load and then times out - no moves occur.
