Stockfish 1.7.1 for Mac OS X

[Tord Romstad]

Hi all,

The Mac OS X version of Stockfish 1.7.1 for Mac OS X is now finally available for download from our web site. This is almost identical to the test version I posted in the main Stockfish 1.7.1 thread two days back, but has a very slightly faster 64-bit binary, and some extremely minor bug fixes in the GUI. The program requires an Intel Mac (please let me know if someone needs a PowerPC version) and Mac OS X 10.5 or later. Actually it has only been tested on OS X 10.6.3, but I think it should work in 10.5 as well.

Thanks to everyone who helped me test this!

Thank you very much for this great engine for Mac users! We now have a chess engine equivalent to Rybka on our Macs and that is really cool

As you mentioned the GUI is not state of the art, but it _works_! And perhaps - as time goes bye - it will be improved. Far more fun to play with than with Scid (that has his advantages in other areas).

Vielen, vielen Dank!

Apparently not. The app is fine, but I get this exception (sf171 quit unexpectedly) as soon as the engine loads.

Perhaps Tord needs to recompile with $CFLAGS = -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5

Hi Tord,

unfortunately the app does not start on my MacBook running OSX 10.5.8 (Core 2 Duo). Got this error message instead:

Any idea?

Do you have execute/write permission on the folder sf171?

Hello Max,

That's the same problem Ian reported earlier in this thread: Unfortunately, it seems that the engine binary doesn't work in 10.5, even though I tried to compile a 10.5-compatible binary.


I'll keep trying.

The reason why I ask is because some cured this kind of problem by upgrading from 10.5.5 to 10.5.8. You already have 10.5.8 although, so it might be something else, like a corrupt/erroneous permissions.

The error code itself relates to LC_DYLD_INFO_ONLY which was introduced in 10.5.6. It is normally thrown as Louis says when the program is compiled on 10.6 and then run on 10.5.x.

After checking I cannot see where Tord makes an allowance for older versions.

It should be easy to recompile with -isysroot/blah.sdk and gcc -mmacox-version-min=10.5.8

Well, that are indeed good news! Looks like a compile of the engine only on _my 10.5 system_ and copied as sf171 into Stockfish.app/Contents/Resources/ should solve this, right?

Ever wondered what this 5gb Xcode developer folder is good for. I'll try my very best.

Thanks,
Max
