# Sample makefile for rpng-x / rpng2-x / wpng for SGI using cc and make.

#       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.
