INSTALL

The usual procedure should apply. After you have unpacked
the sources, type (in the sources top-level directory)

	make

You may also pass several other options such as compiler options
to configure, just type ./configure --help for advice. In particular,
you may experiment with compiler optimization flags, which are added
easily as (assuming you have a bourne-type shell)

CFLAGS="-O3 -ffast-math" ./configure

The build should work with gcc, it also works with the Sun Workshop
compiler and maybe others.

Test gnuchess by typing

	./gnuchess.exe (or ./gnuchess on Linux/Unix)
	easy
	new
	post
	depth 8
	go
	quit

You should see an 8-ply search. Most machines these
days should finish it within a few seconds. If not,
Control-C out, and do 

	depth 6
	go
	quit

instead.

If you got this far, congratulations.

If you want to install the software in some global directory,
by default /usr/local, become root and type

	make install

If you want to install the sources in some other directory
than /usr/local, replace the first line by

	./configure --prefix=/my/favourite/dir 

You can build an opening book which may enhance the value
of gnuchess quite a lot. In order to do so, get the file
book.pgn (see book/README for instructions on how to get it)
and type the following.

	ln -s ../book/book.pgn
	./gnuchess
	book add book.pgn
	quit

This may take some minutes, depending on the speed of your
machines. The book is quite large (180,000 master games).
If you want a smaller book or you do not want to wait, do the
following instead:

	head -30000 ../book/book.pgn > smallbook.pgn
	./gnuchess
	book add smallbook.pgn
	quit

This will make a much smaller book.
