Just noticed that DiscoCheck 5.2 has problems mating with the queen. Timecontrol was 60 moves in 60 seconds.

DiscoCheck had 78 seconds left on the clock at move 121, but the mate scores (99.xx) never got realized and the game ended in a draw. Could it be a bug with my Mac compile, or is this on Windows too?

By chance has anyone been able to make a 32 or 64bit build for Linux?

I installed gcc/g++ 4.8 so I could use C++11 but having a heck of a time getting it to build properly.

Don't think it's the compiler since I was able to use it to build another C++11 engine recently.

Used only the provided shell script on my Mac with gcc 4.7.3. Should be the same on Linux and gcc 4.8.

I did one more update to my DiscoCheck 5.2 upload, as well as the Minace 1.0 upload. It seems I needed to include one more dll file to have it run on Norbert's XP SP3 German Edition machine. Hopefully, it should run on all platforms now.

I am using Ubuntu and GCC 4.8, so I am a bit surprised. As you can see from the script make.sh, compilation is straight forward with Linux/GCC:

Code: Select all

g++ ./src/*.cc -o $1 -std=c++11 -Wall -Wextra -pedantic -Wshadow -DNDEBUG \
	-O3 -msse4.2 -fno-rtti -flto -s

So you invoke the script, obviously with a $1 argument to specify the target file (see the -o command in GCC):

Code: Select all

./make.sh ./discocheck

If your CPU doesn't support SSE4.2 instruction set (popcount), use "-msse2" instead (at least you have prefetch).

To verify that your compile is correct, run

Code: Select all

./discocheck bench

The node count at the end should be 4112589. On my i7-3770k machine:

Code: Select all

$ ./discocheck_5.2_sse4.2 bench|tail -2
nodes = 4112589
kn/s = 1390
