1 # Sample makefile for rpng-x / rpng2-x / wpng using gcc and make.
3 # Last modified: 2 June 2007
5 # The programs built by this makefile are described in the book,
6 # "PNG: The Definitive Guide," by Greg Roelofs (O'Reilly and
7 # Associates, 1999). Go buy a copy, eh? Well, OK, it's not
8 # generally for sale anymore, but it's the thought that counts,
9 # right? (Hint: http://www.libpng.org/pub/png/book/ )
11 # Invoke this makefile from a shell prompt in the usual way; for example:
13 # make -f Makefile.unx
15 # This makefile assumes libpng and zlib have already been built or downloaded
16 # and are installed in /usr/local/{include,lib} or as otherwise indicated by
17 # the PNG* and Z* macros below. Edit as appropriate--choose only ONE each of
18 # the PNGINC, PNGLIBd, PNGLIBs, ZINC, ZLIBd and ZLIBs lines.
20 # This makefile builds both dynamically and statically linked executables
21 # (against libpng and zlib, that is), but that can be changed by modifying
22 # the "EXES =" line. (You need only one set, but for testing it can be handy
