Compiling Jazz

[Max]

Thanks for Jazz!

While building your engine Jazz r421 on my mac (Core2Duo, OSX 10.5.8) I ran into these small problems.

Code: Select all

$ make
Scanning dependencies of target jazz
[  3%] Building C object CMakeFiles/jazz.dir/src/computer/computer.o
cc1: error: invalid option ‘sse4.2’
make[2]: *** [CMakeFiles/jazz.dir/src/computer/computer.o] Error 1
make[1]: *** [CMakeFiles/jazz.dir/all] Error 2
make: *** [all] Error 2

With removing the options WANT_SSE42 and after

Code: Select all

$ make

removing WANT_WERROR with CMake 2.8.4, your engine Jazz compiled well.

Code: Select all

$ ./ucijazz 
uci
id name Jazz 421 (i386)
id author Evert Glebbeek
option name Hash type spin default 48 min 1 max 1024

Looks like a 32 bit binary was compiled by the generated Makefile. Not beeing familar with CMake (which looks interesting btw), is there an option for creating a 64 bit version? Something like WANT_64BIT?

In the list of options, look for CMAKE_OSX_ARCHITECTURES. I usually set that to "i386; x86_64" which produces a fat 32/64 bit binary.
I lately forgot to include the 32 bit build, as you've noticed...

Thanks Evert,

got it compiled to 64 bit.

Is there an issue with the analyze mode? With Stockfish and Shredder Classic gui, Jazz stops calculating after about 5 seconds. And in SCID the engine output windows remains empty.

Well, that rather depends on your point of view.
I haven't actually implemented a special "analysis mode", so I'm not surprised it doesn't work if you try to use it. I will look into it though, what you describe doesn't sound good...
