New release Pedone 2.1

[Wolfgang]

Thanks Fabio,

will there be a release soon(er or later)?

[Fabio Gobbato]

I would like to test some other things and maybe for January I will release a new version.

Hello Fabio,

Just to confirm you that your armv8 build I working on a Rasperry Pi 4 with Linux 64 bits.

Would be Nice if you tell what choices you made for compiling (gcc? Flags?)
Many armv8 builds don't work on Pi 4 because they are only adressed to Android it seems with ndk and/or Android specific libs.
So it's interesting to know why yours is working like a charm on this platform.

I don't know exactly why but this is the compilation command:

Code: Select all

aarch64-linux-android21-clang ./main.c -s -static -pthread -O3 -flto -std=gnu11 -DNDEBUG -Wall -Wextra -lm -march=armv8-a -fPIE -o ./Pedone_armv8

Maybe -fPIE could make the difference but I'm not an expert of arm environments.

I don't know exactly why but this is the compilation command:

Code: Select all

aarch64-linux-android21-clang ./main.c -s -static -pthread -O3 -flto -std=gnu11 -DNDEBUG -Wall -Wextra -lm -march=armv8-a -fPIE -o ./Pedone_armv8

Maybe -fPIE could make the difference but I'm not an expert of arm environments.

Thanks for your input. I don't know why either ^^ It could be one flag or perhaps the compiler itself or even the OS you are using. Your clang compiler mentions linux and android and i know some compile with ndk and others with gcc...

Now it's just a matter to compare with methods of other people that do build for armv8 but that only work with android and do not work with aarch64/Arm64 Linux architecture, and see if they can reproduce with same compiler as you.

Thanks again Fabio.

Fabio makes static builds. May be your environment needs static builds (with all necessary libraries in the executable).

Yes it could be that also. May be you could try add -static to one of your armv8 android build and let me try it on rpi4 to test it. But i think we cannot follow this talk on Pedone topic. If you agree to do some testing please tell me on this topic : http://www.talkchess.com/forum3/viewtop ... =2&t=75909
