Why AVX512? Why not AVX2?
from yaneuraou.
../script/build.sh -a AVX2 -c clang++ -e MATE_ENGINE -t normal
In the latest version of YaneuraOu, use either TANUKI_MATE_ENGINE or YANEURAOU_MATE_ENGINE to build the Mate Engine; specifying MATE_ENGINE is for older versions. Please try the latest version.
Furthermore, I think bench command is not supported by the Mate Engines.

Thanks for that advice. Sorry, I got very confused trying to reproduce errors observed by other developers. I think what they are trying is something like:
#!/bin/bash
../script/build.sh -a AVX2 -c clang++ -e YANEURAOU_ENGINE_NNUE -t normal && \
../build/linux/NNUE/YaneuraOu_NNUE-linux-clang++-normal-AVX512 bench 16 1 5 test.sfen depth
$ ./build.sh
...
./build.sh: line 3: 83466 Illegal instruction (core dumped) ../build/linux/NNUE/YaneuraOu_NNUE-linux-clang++-normal-AVX512 bench 16 1 5 test.sfen depth

Make sure that the binary you build and the binary you launch are the same file. Why are you trying to launch the AVX512 version when you built the AVX2 version?
grep flags /proc/cpuinfo | uniq
In addition, check your CPU environment, because it seems that running the AVX512 version will not work without at least avx512f
or avx512bw
. Maybe other flags are also needed to run, though.

Why do you need three rooks on the board?
A board with three rooks is illegal. Normally there are two.

Good question. @WandererXII advises that for Lishogi this will not be required after all.
