Re: KnightX v2.1b, June 2020

http://technochess.free.fr/Archive/Knightx21b.zip for the Windows version.

Just replace the appropriate part of the address with the version number you are looking for.

EDIT: I did not succeed the same way with the Linux version, maybe it is named differently.

Re: Orion 0.7 release

Another year, another release :) I'm happy to announce a new version for my little engine Orion ! A lot of work, with a complete rewrite of evaluation function and tuning method. Orion now supports Syzygy tablebases and embeds its own KPK bitbase, both should help a lot in endgame phase. More detai...

Re: GCC 8.1 vs GCC 10.1

Things are worse than I thought. I tried to compile the new Raven 1.00. With GCC 8.1 everything's OK. With GCC 10.1.0-3 I get a 200 kB error file, the start of which is this: That's new with GCC 10 and actually caused by sloppy code. External variables should be declared as "external". Try compilin...

Re: GCC 8.1 vs GCC 10.1

Did you remember to run strip after the compile finishes? That usually reduces the size a lot. If you build a static executable, it will be much larger than one that loads the DLL files dynamically. But if you do not link a static executable, you will have to have the DLL files available for the ex...

Re: GCC 8.1 vs GCC 10.1.

Have you tried -s flag for size? I mean, compiling with -O3 -s instead of only -O3 . It worked with older versions of GCC and G++ though I do not know if this flag still exists or has been removed. The size flag is listed as -Os under this blog article from 2019 , which explains that -Os takes -O2 ...

GCC 8.1 vs GCC 10.1

Hi all, I am not a programmer but still have successfully compiled some C or C++ engines using GCC 8.1. I have now installed GCC 10.1 and I noticed that the file sizes I obtain using it are much bigger than the ones made with 8.1. Also, the executables are slower. I have an i5-4690K (Haswell) CPU an...
