- # Sample makefile for rpng-x / rpng2-x / wpng for SGI using cc and make.
- # Greg Roelofs
- # Last modified: 7 March 2002

- # The programs built by this makefile are described in the book,
- # "PNG: The Definitive Guide," by Greg Roelofs (O'Reilly and
- # Associates, 1999). Go buy a copy, eh? Buy some for friends
- # and family, too. (Not that this is a blatant plug or anything.)
- #
- # Invoke this makefile from a shell prompt in the usual way; for example:
- #
- # make -f Makefile.sgi
- #
- # This makefile assumes libpng and zlib have already been built or downloaded
- # and are both installed in /usr/local/{include,lib} (as indicated by the
- # PNG* and Z* macros below). Edit as appropriate--choose only ONE each of
- # the PNGINC, PNGLIB, ZINC and ZLIB lines.
- #
- # This makefile builds dynamically linked executables (against libpng and zlib,
- # that is), but that can be changed by uncommenting the appropriate PNGLIB and
- # ZLIB lines.
