HTTP API for Syzygy (and Gaviota) tablebases. Based on @ddugovic's Stockfish with variant support, and libgtb by Miguel A. Ballicora.
Install libevent2:
sudo apt-get install build-essential libevent-dev
Build and install libgtb
git clone https://github.com/michiguel/Gaviota-Tablebases.git
cd Gaviota-Tablebases
make
sudo make install
Finally:
cd src
make -f Makefile.regular ARCH=x86-64-modern build
make -f Makefile.atomic -B ARCH=x86-64-modern build
make -f Makefile.giveaway -B ARCH=x86-64-modern build
Via BitTorrent: http://oics.olympuschess.com/tracker/index.php
Atomic and Suicide/giveaway tables are not beeing widely distributed, so they probably have to be generated.
