Posix ports of some recent version of Toga II

These are posix ports of some recent versions of Toga II. They have been reported to work on Linux, MACOSX and BSD.

Sources

toga2-14b5c_posix.tar.gz
toga2-142JD_posix.tar.gz
toga2-1.4.1SE_autoconf_eng.tar.gz (this is a version that uses autoconf and automatically installs an .eng file so that it will be visible in xboard and any other GUI supporting this standard).

Some linux binaries

License

Toga II is a Fruit 2.1 derivative. Fruit 2.1 is licensed under the GPL v2 or later. The same applies to these ports.

Remarks

I think the sources will still compile and run under windows but I have not seriously tested this.
The following patch contains the difference between the windows and posix sources.
Here is Doxygen generated documentation of the port of Toga II 1.4.1SE.
Toga II 1.4.1SE has now made it into the Debian Sid and Ubuntu Jaunty repositories! See http://packages.debian.org/sid/games/toga2 and https://launchpad.net/ubuntu/jaunty/+source/toga2/1.4.1.1SE1-1. This small patch was used to make the number of threads a configurable UCI option. Hopefully Fedora and the BSD's will follow soon.
For the time being the Intel compiler (a free download) generates faster code than gcc. The binaries were compiled with the Intel compiler using this makefile. Note that the big secret for generating fast binaries (both with gcc and icc) is "profile guided optimization". See the instructions in the supplied makefile.
For profiling or to quickly test a compile you can use ucibench.
These ports include a fix for a small bug in the opening book handling code of the MP versions of Toga II.
There was a beta version of Toga II 1.4.3JD here but I removed it as it would give a bad binary with the Intel compiler (it worked fine with gcc). The final version of Toga II 1.4.3JD should be out soon.

More stuff

Here is an experimental version of Toga II 1.4.1SE which allows you to set the number of threads at arbitrary times (it compiles fine in Linux and Windows). Cyclone and Deep Learning Toga are other versions with this capability. This feature is required to make Toga compatible with the upcoming "cores = N" command in Polyglot (the "cores=N" command is part of the new winboard protocol specification at http://home.hccnet.nl/h.g.muller/engine-intf.html).

Here is roughly how to change the number of threads in Toga II 1.4.1SE.

Other Fruit/Toga derivatives

Cyclone 2 (binary: cyclone2-1cpu-linux.intel)
Cyclone 2.1

IMPORTANT: Cyclone is a fork of Toga II 1.4b5 which has been relicensed under the GPL 3. Code from Cyclone cannot be reused in Fruit/Toga which is GPL 2+.

GrapeFruit 1.0 alpha 3
DeepLearningToga 1.5.21a (binary: DLT1.5.21a.intel )

More ports by Benigno Hernandez (untested).
