Linux compiling for ARM Cortex-A53 processor #7

Closed rontant closed 3 years ago

rontant commented 4 years ago

I tried to compile Tucano on a rock64 SBC running Ubuntu Linux and got errors. Rock64 has the following architecture infos:

Here are the errors:

Please help.

Hi, I don't know if you used the latest source code. I have made some changes related to those functions in order to compile on linux for TCEC. If not try to get the latest version. Let me know the results. I'm not familiar with ARM but please see below the compilation options used, there are some different options, maybe this helps.

gcc -Wall -march=native -g -DEGTB_SYZYGY -O3 -flto -o tucano src/*.c src/fathom/tbprobe.c -lpthread -lm

Thanks for your reply. I have tried again as per your suggestion. Here are the errors I got:

Any idea?

So far I have successfully compiled many engines successfully on this machine such as Stockfish, Xiphos, Winter, Weiss, Vajolet, Ethereal, Fabchess, Marvin, Monolith, Defenchess, Arasan, Demolito, Pedone, Laser, Igel, Rubichess, etc.

Thanks.

Those seems to be errors related to the bitscan functions, that's my guess. I will take a look at tucano and compare to the engines you mentioned. Maybe I am doing something different. I will take a look at let you know. Keep you posted.

Hi, I did some research on those errors and seems to be related to the compile options. Maube you can try to use the ARM flags as described in the makefile for ethereal. seems you can include the flags ARM7 or ARM8, i'm not sure. take a look below. let me know how it goes.

Any idea?

So far I have successfully compiled many engines successfully on this machine such as Stockfish, Xiphos, Winter, Weiss, Vajolet, Ethereal, Fabchess, Marvin, Monolith, Defenchess, Arasan, Demolito, Pedone, Laser, Igel, Rubichess, etc.

Thanks.

That's good news. I will incorporate this information for the compilation. I will help others. Yes, you can remove the -DNDEBUG option. this is used for development and it is defined in the file globals.h. Thanks for compiling it ! that's was good.

With this "makefile" I can use the following command to compile:

root@rock64:~/Tucano/src# make -j4 nopopcnt armv8

My first test pitting it against another chess engine went well.

1) For Tucano 8.29, I got 21520576 as the signature from running "bench". Is it correct?

2) On the main page text for Linux compile command, I suggest you remove the .exe extension.
