Unable to run after compile on Mysys2

[magicianfromriga]

Hi, I ran the make command on Mysys2 after cloning the git repository. I am unable to run Ethereal after it compiles (without errors). Can you please include a way to compile it on the readme like the Stockfish repo? Thanks!

Could you please include more information? I would expect a simple make to work on all systems with at least popcnt support. However,I cannot say I've ever compiled using Mysys2.

Can you provide Mysys2's version, the command you used to make the engine, your CPU name, and what you mean by "unable to run Ethereal"? Does it throw an error message? Does it stall? Does it refuse to open?

Hello all,

Is Mysys2 something like Cygwin ?

For your information, i don't know if on an RBP4 (armv8) i have to use "make release" or make "armv8" , using armv8 option , the option -m64 is not recognised (i can provide details) The first compile line of "release" part is working fine on my Ubuntu-server-aarch64 on the RBP4 I compile (release) it also on an old Core i5 (all versions are working) Il also compare then using bench option and grep OVERALL to see the difference of nps and I was surprised because there is not a lot of difference between the instruction set used AVX2 POPCNT and so on .... I'm very impressed by the very high nps (over 2000000 by core) value that show the coding+compilation directive is optimized

The engine is used on Robot on Lichess (don't believe what i write on description : (it is not anymore Minic Engine and will change soon)

Test it on :

https://lichess.org/@/BotVMinic

https://lichess.org/@/BotVMinic i https://lichess.org/@/BotVMinic will switch on the PC after this mail

Regards

I have an i7-4790k. It supports BMI2 instructions. I ran make first. It compiled, then when I tried to run the engine it said error - libwinpthread -1.dll is missing. This has never happened to me when I compiled cfish or stockfish. Can you please suggest what to do?

Is under Windows a -static compilation ? Under Linux it seems to be

Your compiler is not POSIX compliant. A POSIX compliant compiler is needed to handle Ethereal's threading, as it does not fallback on Windows things. Perhaps you can download that .dll and place it in the same folder. Otherwise, I personally don't recommend non-POSIX gcc installations. https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/8.1.0/threads-posix/seh/x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z is what I use for Windows.

Ok thanks, will try this out!

Hi, Can you please post more detailed instructions? How do we clone it without Mysys2? How do we compile it? I am not that well versed in coding so I don't know how it's done. Sorry for the inconvenience. Thank you!
