xvier is a simple game where you and your opponent alternately throw stones into free columns. The stones pile up in the columns, and the goal is to get four stones in a row, in a column or diagonally. The game compiles without modifications at least on Sun Sun4 SunOS 4.0, 4.1.1 Sun Sun3/60 SunOS 4.0 IBM RS6000 AIX 3.1 HP 9000/720 HP-UX 8.05 HP 9000/350 HP-UX 8.00 DEC VS3100 Ultrix-32 V3.1 DEC DS5400 Ultrix 4.2 Sequent Symmetry Dynix 3.0.17.9 To install xvier: 1. If you use Makefile.std, copy it to Makefile and choose locations for the X11-binary (default: /usr/local/bin), the game program (default: /usr/local/lib), and the manual page (default: /usr/local/man/man6). If you use imake, type "xmkmf" and "make depend". 2. Type "make". 3. Test the game with "./xvier -prog ./xvier_prog" 4. If it works, type "make install" (and "make install.man" with imake). If you have problems with the compilation, look at the comments in Makefile.std or Imakefile. The game program uses a simple search tree, and the levels correspond to the depth of this tree. Thus the higher levels are quite slow, but normally I don't need them to get a good opponent ;-) It's interesting that level 1 seems to be weaker than level 0.
