Chess Engines binaries for Raspberry Pi 4 Linux 64 bits

[AlexChess]

Tried to compile Stockfish-dev (13) for PI4 and Ubuntu ARM64, but from it I get this error:
alex@alex-Parallels-ARM-Virtual-Machine:/test/Stockfish/src$ make -j build ARCH=armv8
Default net: nn-62ef826d1a6d.nnue
Downloading https://tests.stockfishchess.org/api/nn ... d1a6d.nnue
Segmentation fault (core dumped)
make: *** [Makefile:758: net] Error 139
alex@alex-Parallels-ARM-Virtual-Machine:/test/Stockfish/src$

...while doing the same from Mac mini M1 (for M1 architecture) it works perfectly!

Hi!

Is there a way to save Cutechess tournament/layout settings on PI4 / Ubuntu ARM64? Every time I must re-add all engines and setup tournament options...

PS: I have made a desktop launcher to avoid to execute it from terminal, too

[AlexChess]

Could you also try to compile Igel 3.0 NNUE for PI4 / Ubuntu ARM64?

Thank you!

Hi Alex

For igel I had downloaded the release:

https://github.com/vshcherbyna/igel/arc ... 0.0.tar.gz

and in the src directory I did

Code: Select all

mkdir -p weights

In weights I did

Code: Select all

wget -c "https://github.com/vshcherbyna/igel/releases/download/3.0.0/ign-1-139b702b"

cd to src dir and change in makefile with editor:

EVALFILE = weights/ign-0-9b1937cc

to

EVALFILE = weights/ign-1-139b702b

I changed

LIBS = -std=c++17 -mpopcnt -pthread

to

LIBS = -std=c++17 -pthread

because the processor I use does not know this instruction.

save+type make.

Greetings

For Stockfish:

could you do please in terminal:

lspcu
or
less /proc/cpu

and post everything after

Code: Select all

flags:

please?

And: Did it load the net actually, because the segfault happens there?

Hi dear,
Done, but I get errors. Note that Silicon M1 supports popcnt and sse3 | sse41 but not bm2 or avx2 avx 256 avx 512 (at least when I use Windows 10 ARM64 -> intel-x86 translated engines)

Thank you for your support!! 22:00 now but tomorrow I will retry

In src without 'make' please copy+paste+enter:

Code: Select all

g++ -Wall -std=c++17 -pthread -msse -msse2 -msse3 -msse4.1 -O3 -march=native -flto -DEVALFILE=\"weights/ign-1-139b702b\" *.cpp nnue/*.cpp nnue/features/*.cpp fathom/tbprobe.c -DNDEBUG -DEVAL_NNUE=1 -D_BTYPE=0 -DSYZYGY_SUPPORT=TRUE -DUSE_SSE2=1 -DUSE_SSSE3=1 -DUSE_SSE41=1 -o igel

The net is loaded with your instructions, but it gives errors also starting with "g++"
