# Sample makefile for rpng-x / rpng2-x / wpng using gcc 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?  Well, OK, it's not
#	generally for sale anymore, but it's the thought that counts,
#	right?  (Hint:  http://www.libpng.org/pub/png/book/ )
#
# Invoke this makefile from a shell prompt in the usual way; for example:
#
#	make -f Makefile.unx
#
# This makefile assumes libpng and zlib have already been built or downloaded
# and are installed in /usr/local/{include,lib} or as otherwise indicated by
# the PNG* and Z* macros below.  Edit as appropriate--choose only ONE each of
# the PNGINC, PNGLIBd, PNGLIBs, ZINC, ZLIBd and ZLIBs lines.
#
# This makefile builds both dynamically and statically linked executables
# (against libpng and zlib, that is), but that can be changed by modifying
# the "EXES =" line.  (You need only one set, but for testing it can be handy
# to have both.)
