I compiled a few more chess engines for Mac (x86_64 binaries). I also built up a quick and dirty website for all those engines, as it's still better than the ftp directory I had before. It will get better with time.

New engines :
• Crafty 23.6
• Eia 0.1
• Octochess r5178
• Sting SF 130131
• StockFish 2.3.1
• Vice 1.0

(Yes, I know that Stockfish and Sting SF are a bit old now, but I had them sleeping on my harddisk, so...

)

If you know some engines for Mac that I forgot to add to my list please do not hesitate to contact me. If some more engines could be compiled (or you have compiled them and I didn't) please contact me as well.

Thanks Julien for your Mac support!

BTW, Octochess 5178 compiles well with gcc 4.7.3 (macports) and -flto. So it could be a gcc 4.8.1 compiler issue.

Flto gives about 17% speedup on my old Mac.

gcc 4.7 with -flto:

Code: Select all

./octochess5178-g47 --threads 1 --depth 18 --memory 1 --moves 1 auto
Octochess

Thanks for the info, Max.

Pity they let such a big bug make it to the release. As I'm on holidays I don't think I can update my compiler through my mobile's tethering.

I'll soon release a (big) handful of new compiles though.
