It has been tested with gcc 2.7.2.3 under Linux and -Solaris and with Microsoft Visual C++ 5.0 under Windows 95. Brief -instructions for compiling the programs are included at the top of the -makefiles; makefile.unx is the Unix version, and makefile.w32 is (you -guessed it!) the version for 32-bit Windows. libpng and zlib are required. - ----------------------------------------------------------------------------- - -License - -The source code to the demo programs may be used and distributed freely -(even if you didn't buy the book--but feel free to do so at any time), -subject to the terms of the following BSD-like license: - - Copyright (c) 1998-1999 Greg Roelofs.
