The file is produced if option --uci is not specified and if the following variable is set in gnuchess.ini:

Typically, this file is named adapter.log, but any other name will do the job.

log.nnn

This file is written if command name was requested. The contents are the opponent’s name and the game in coordinate algebraic notation.

game.nnn

This file is written if command name was requested. The contents are the opponent’s name and the game in portable game notation (PGN).

players.dat

This file is written if command name was requested. The contents are the statistics of games. This is the format of each line:

gnuchess.debug

This file contains internal information that is useful for debugging purposes. For this file to be written, it is necessary to define preprocessor directive DEBUG. Hence, when installing the program, instead of

./configure
make
make install

Use the following commands:

./configure CPPFLAGS=-DDEBUG
make
make install

When analysing a bug, this file could be very helpful. Users are encouraged to provide it.
