Notes:

  • Read the PKGBUILD for extra build options.

    • Clang improves performance by about 2.22%
    • Profile-guided optimization improves performance by about 9.75%

  • CPU detection in the Makefile is bypassed because it can result in illegal instruction errors. For specific CPU support, use CFLAGS/CXXFLAGS in makepkg.conf, but performance improves by only about 1.28%.

  • Large boards and all variants are enabled to support xiang qi and shogi. Performance decreases by about 29.97%.

  • NNUE files are not included. Information about what they are and how to use them is available at Fairy-Stockfish/NNUE.

  • Scripts are provided for convenience:

    • xbfs-shogi and xbfs-xiangqi to launch xboard
    • fairyfishgui is included with python-pyffish
